• How can see what processes makes my server slow?

  - by Steven

  All my websites on my server are extremely slow or not loading at all. Even server admin (Plesk) will not load some times. There's been no changes to the sites for the last coupple of months. How can I see what processes is making my server slow? My environment looks like this: Server: VPS running Linux 2.8.x OS: Centos 5 Manage interface: Plesk 9.x Memmory: 1024MB CPU: 2.2GHz My websites run on PHP and MySQL. I finally managed to telnet (Putty + SSH) in to my server. Running top did not show any processes using more than max 2% CPU and none were using exesive memmory. I also got a friend to install a program that checks the core files, and all seemed fine. So I'm leaning towards network issues or some other server malfunction. But I'm not able to find out what can be wrong. Here are some answers to Sean Kimball: I don't run mail services on my server yet There are noe specific bandwidth peaks. Prefork looks like this <IfModule prefork.c> StartServers 8 MinSpareServers 5 MaxSpareServers 20 ServerLimit 256 MaxClients 256 MaxRequestsPerChild 4000 </IfModule> Not sure what you mean with DNS question. But I think it's up and running. There are no processes running wild Where can I find avarage load? Telnet is disabled and I have to log in using SSH :)

• No access to Windows 2003 admin shares

  - by ARomo

  This is the environment: Several Win 2003 SP 2 servers and several Win XP SP2 & SP3 clients. All in the same LAN. Firewall is disabled everywhere. No recent Windows updates or configuration changes. This is the problem: Since last Thursday, I log on to any other server or workstation as any regular (non-admin) user and I fail to be able to open ADMIN SHARES ONLY (namely \\server1\c$, \\server1\e$ and \\server1\admin$). The error message is: "\server1\c$ is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions. Multiple connections to a server or shared resource by the same user, using more than one user name, are not allowed. Disconnect all previous connections to the server or shared resource and try again." I can, however, open the same shares if I use FQDN or IP address: \\server1.domain.local\c$ \\172.0.0.1\c$ Other shares do not have this issue and I can open them without any issue. Any ideas or suggestion would be truly appreciated. Thank you in advance.

• Is there an Installer Analyser tool that can list what Registry Keys will be created?

  - by EvoGamer

  I can think of 3 ways to achieve my goal: Create a clean VPC, install a given piece of software, and compare the before and after states. Somehow reverse-engineer the installer. Somehow redirect the output of the installer in question so that all registry calls and copy/move file commands are recorded, but not executed. The first option can be done manually, or potentially automated, but I feel it's rather OTT for my needs. The second could cause all sorts of licencing issues, not to mention it may not always return a correct result. Also, without delving into hex editing, I can't think of a way that it would be possible to do manually (some installers - eg Anti-Virus software - may react unfavourably on automated attempts to investigate the installer). The third option shows the most promise, although if the first could be stripped down into a lightweight throwaway environment, it would work pretty much the same way. However, I'm not sure how to do it. So my question is: What tools are available (if any) and/or how could I find out this information manually? I'm not looking to reverse-engineer anything (if I can help it), but I just want to know exactly what changes are being made to my PC by a given piece of software.

• Oracle: 1 Large Server vs. 2 Smaller Servers?

  - by nvahalik

  We are in the planning stages of setting up our production Oracle 10gR2 environment. Our budget gives us the ability to buy 2 processor licenses of Oracle DB Standard Edition. We have minimal experience with Oracle so I'll defer to anyone who has used it. We are trying to decide if we should set up a single dual quad-core box or 2 individual quad-core boxes in a RAC configuration. Our DB right now is about 60 GB, and at our peak, we'll have up to 150 concurrent users. Most of the big stuff is done via batch processing at night. My gut tells me that having 2 boxes in a RAC configuration can't be a bad thing because it provides a true hardware failover solution. DB stored in a shared LUN on a SAN via iSCSI. Plus if we ever need to add capacity, we already have boxes in place that can be upgraded with extra procs (I assume with zero downtime, since it's set up in a RAC config) if we add extra licenses, or RAM. Does RAC have any performance penalties? Will it add extra latency? Is there any true advantage for having dual processor boxes running these systems? If we build out the Oracle boxes with special hardware: hardware iSCSI cards, TOE NICs, will these boxes be solid? We are deploying on 64-bit Windows. So what would you do? One box or two?

• Mod_pagespeed, Varnish and Apache cache issues after new code pushes

  - by WerkkreW

  I have a rather strange issue. In my environment we are running a load balanced cluster of 8 apache servers with a master-master MySQL backend. In front of apache we have Varnish in the cache layer. We have been running Apache mod_pagespeed for several weeks now and for the most part it has been working great. The issue arises when we do fresh code updates from Git, and and/all of the JS/CSS assets change. Basically the problem appears to be two fold. One, after the code push we generally take the opportunity to flush varnish, restart apache, and restart varnish. In doing this all of the mod_pagespeed combinied/minified files are cleared out ensuring that all of the new JS/CSS assets are fresh. The problem is, upon doing this the file names that mod_pagespeed creates change, but the old files (appear) to be still cached for many people client side leading to very unexpected results. However, if we do not restart apache, the changes to the files may or may not appear client side due to the cached minified assets. The simple solution is to disable mod_pagespeed, however I would rather not do that as it has made a fairly large impact in performance. I feel as if there must be a better way to deal with the inconsistencies in cache between the client and server to prevent having people to go to great lengths or perform a large number of page refreshes to see a working page. I can provide configuration snippets if anyone needs them. If you would like to inspect the site, source, headers, or anything try the following addresses: http://wellplayed.org http://wellplayed.org/tv Thanks in advance!

• What needs to be considered when setting up for Linux Development? [closed]

  - by user123586

  I want to set up a box for Linux development. I have a working linux install with the usual toolchain and an IDE. I'm looking for advice on how to approach structuring accounts and folders for development. As the Perl folks say "There's always more than one way to do it." Left to my own devices, I'll come up with several unproductive ways of doing it before figuring out what an experienced Linux programmer would think obvious. I'm not looking for instructions to follow for a specific set of tools or a specific software package. Instead, I'm looking for insight into what decisions need to be made and how to make them, with understanding of the advantages and disadvantages of each individual choice. These are some of the questions that come up: Where to put sources Where to put built object files and libraries where to install what to set in environment variables what compiler flags matter and how do you manage them across several types of builds what configuration entries to make in an IDE how to manage libraries to support multiple environments how to handle different build versions such as debug vs release, or cross platform builds If you are an experienced Linux developer, the answers to these questions may seem trivial and obvious. I'd like to learn to make decisions about these questions that result in as little manual configuration as possible, given some existing sources, a particular IDE, or no IDE at all, a paticular set of development libraries etc. At this point you're probably thinking: Can you be more specific? Sure. But remember that I'm trying to learn how to think about this stuff, not just follow a recipie for a specific set of results. Example: Setup a project that uses CMake for some of its components, autogen.sh followed by configure for others and just configure for a few more: debug builds without an IDE debug builds in NetBeans debug builds in Eclipse debug build in Visual Studio all of the above with release builds for Linux, Mac and Windows. So... **What are your thoughts on an approach that works for all four? Do you have any advice on what to read?**

• Mercurial hook fails on Windows

  - by Nick Hodges

  I am trying to use the headcount hook (https://bitbucket.org/dgc/headcount/overview) with my main develop repository. I pulled the code and placed it in C:\Python26\Lib\site-packages. I made the following entries into my hgrc file: [hooks] pretxnchangegroup.headcount = python:headcount.headcount.hook [headcount] push_ok = * commit_ok = * warnmsg = %(headcount)d new heads detected. You may not push new heads to this repository. debug = False All this is as per the install instructions. I then cloned the repository, created a branch, committed a change to that branch, and then issued: hg push -f as a test. However, this fails with: C:\junk\htmlwriter>hg push -f pushing to c:\code\htmlwriter searching for changes adding changesets adding manifests adding file changes added 1 changesets with 1 changes to 1 files transaction abort! rollback completed abort: pretxnchangegroup.headcount hook is invalid (import of "headcount.headcou nt" failed) I then ran this: C:\Python26>python c:\Python26\Lib\site-packages\headcount\headcount.py Traceback (most recent call last): File "c:\Python26\Lib\site-packages\headcount\headcount.py", line 2, in <modul e> import mercurial.node ImportError: No module named mercurial.node I'm far from a python expert, so can someone help me figure out how to get the headcount hook to run inside my mercurial environment? Details: Windows 7, Mercurial 1.7.2, TortoiseHg 1.1.7

• Office 2010 Trust Center settings: How to enable data connections in the "old" way?

  - by GSerg

  We're planning an upgrade Office 2003 - 2010 and have identified a big problem. In Office 2003, if the workbook you're opening contains a query table that fetches data from a data source automatically (upon file open or in certain intervals), then a security dialog pops up - whether you want to allow that. If you say Yes, the queries will refresh automatically when they need to. If you say No, the queries will not refresh automatically, neither on file open nor on time intervals, but you will be able to refresh any of them manually at any time by right-clicking and selecting Refresh. There is also a registry parameter to say, Don't display that dialog, just allow the queries. This is exactly what we want. On users' computers we have the registry parameter applied, so the users never see any dialogs. On developers' computers the parameter is not applied, so every time a file is opened the developer decides whether to allow the auto-refreshing for the current session. Usually the answer is No, because for developing, it is essential to not have quieres refresh when they want to, but instead, refresh them when the developer wants. The problem is that in Office 2010 which we are testing we can't find a way to achieve this functionality: The allow/disallow messages are now grouped into one yellow button, that either allows everything or disallows everything (including, say, macros, if macro security is set to "Disable, but ask"). If you don't click the yellow Allow button, the queries are disabled completely, not just for automatic execution. You cannot right-click and refresh a particular query -- doing that would summon a security dialog prompting for enabling queries, and if you say Yes, all queries in the document will be enabled for auto-execution and will start executing immediately. This sort of ruins our development environment. Is there a way to get the trust thingies in Office 2010 to work in the same way as before? Is there a yet another registry parameter to say, Prompt for auto-refresh, but allow manual refresh even when auto-refresh is disabled?

• Fake demostration software for command line

  - by Joe

  I'm looking for some software that would be useful for giving demonstrations. I regularly have to show the effects of scrips ect to classes while talking about their effects, and equaly regularly I have finger trouble and have to rewrite various commands - wasting class time and general energy. I'd like to be able to record a sequence of commands in advance, and then play them back at the speed of my choosing. So I might have a file that containes the commands: echo "hello world!" ls ls -l ls -l | sort I'd like to be able to play these commands back by typing similar ones in. So I'd have a blinking command prompt and if I typed 'echo "hxxx' the command prompt would read home$echo "hell and if I typed any other letters the terminal would fill up with the remainder of the command until I press enter, when it executes the command. The point is that even if I screw up the command when typing it, the command that I'd prepared in advance would be executed. My question is - does similar software exist for giving demonstrations? or even, is this an easy thing to script up...? EDIT - two quick things first of all I'm on osx - but it would be nice to get a general solution for other people who arrive here from google. and second a lot of the comments/answers are concentrating on, in effect, making it fast and easy to enter long commands by means of hotkeys and the like. Actually I'd like it to at least look like I'm typing live - that's why I put in the bit about the one-to-one keymapping, but I don't think I explained that quite as well as I could have...

• Tried to install Mint to a Flash Drive. Now I can't boot from the main hard disk.

  - by Dan

  Hello, all. I'm kind of new to Linux and I need some help. I wanted to install a Linux distro to a flash drive so that I can have a portable OS with all my settings, programs, etc. wherever I go. So I fired up a Linux Mint Live CD and installed Mint to the flash drive, and this seems to work OK. But now, whenever I try to boot up my system normally without the flash drive plugged in, it doesn't seem to work. It basically hangs for a bit, and then I get the following prompt: error: no such device: (some long hex val) grub rescue> However, when I try powering my system up when the USB is plugged into the computer, it gives me an option between using the OS installed on my USB and the OS installed on my HD. Selecting the latter, everything loads up just fine. I'm guessing that installing Mint to the flash drive somehow messed with my native Grub installation, but, again, I'm kind of new to Linux, so I'm not sure exactly why. Any help is greatly appreciated.

• Anyone have a script to delete a specific local windows profile?

  - by Jordan Weinstein

  I'm looking for Powershell (preferred) script, or .CMD or .VBS, to delete a specific user profile on a workstation (WinXP) or terminal server (2000, '03 or '08). I know all about the delprof utility... That only allows you delete based on a period of inactivity. I want a script to: prompt admin for a username delete that username's profile and to delete the entire profile - registry hive too (not just the folder structure within Documents and Settings). The same way it would if you went to My Computer Properties Advanced tab User Profiles Settings and deleted profiles from there. Any ideas? All I can think of is doing an AD lookup to get the SID of the user specified, then using that to delete the correct registry hive too... something simpler would be nice though... Basically, my HelpDesk used to be local administrators on our Citrix servers and a common fix for various issues was for them to delete a user's profile on the citrix server(s) and have that user log back in - voila, whatever issue they had was resolved. Going forward, in new Citrix environment, they will no longer be local admins on those boxes, but still need to be able to delete profiles (deleting the entire profile: folder and reg hive is key). thanks.

• postfix email gateway

  - by k-h

  I am setting up a postfix email gateway. It will not hold any mail but will accept email for my domain and forward it to another internal mailserver and relay mail out from the internal server. One of the main problems is that I am working on a live running system and this will be an upgrade so I am using a test domain which I will change at some point to the real domain. I tried various methods but found the simplest way (that worked) was to use a script to create an aliases file (from ldap entries). There are various problems with this method. The main one being that the entries can't be of the simple form [email protected] because the gateway doesn't know where to send them. They have to be of the form: [email protected]. What I would like doesn't seem hard but I can't get my head around the postfix documentation. There seem to be various ways but none of them seem to work. Most of the examples I have found on the web assume the mail is going to end up on the server. I want a list of users somewhere, preferably of the form: user1, user2, etc rather than [email protected] (I can easily generate this list) and I would like postfix to forward all email to example.com to a particular server: ie realmailserver.example.com. Can anyone suggest clues as to how I might do this?

• Multi-partition USB stick

  - by nightcracker

  In my freelance job as "the dude that fixes your computer" I have an extremely handy tool, a bootable USB stick with Ubuntu LiveCD that allows me to recover and investigate in a known, working environment. Now, I want to reformat this USB stick and reinstall with Casper-RW persistance. I did this a few times before with a FAT-formatted USB stick. It was a horror. The USB drive corrupted constantly, by people accidently removing the USB stick, the computer not properly shutting down, ETC. Now what I want to create a multi-partition USB stick so I can put Ubuntu on a ext partition, but still be able to store some Windows stuff in it, by having a secondary FAT partition. However I read somewhere that Windows will only check the first partition on USB sticks, giving a problem with the first bootable linux partition. Is this possible on some way? EDIT Perhaps it wasn't clear what the problem is. The problem is that I read somewhere that Windows will only recognize the first partition on a USB stick. But I want two partitions, a ext partition and a FAT partition. No issues so far, but in order to be bootable the ext partition must be the first one!

• Many clients on a wireless AP for UDP broadcast packets

  - by distorteddisco

  I asked this question on StackOverflow and was directed over here, so I'd appreciate any advice. I'm deploying a smartphone application as part of a live music performance that depends on receiving UDP broadcast packets from a wireless access point. I'm guessing that between 20 and 50 clients will be connected at any one time. I'm aware that a maximum of 20 clients per access point is advised, but as the UDP broadcast packets are ground through the LAN, how would I be able to link multiple APs together? I'm looking for recommendations on a suitable AP for this. The actual data transmission rates are very low - only a few kB/s - as I'm just sending small messages to the smartphone apps, and there will be no WAN internet connection. I tried it with a few connected peers on an adhoc wireless connection without any problems, but ran into dropped packet issues on an old WRT54G running ddwrt, though it's in pretty rough shape. What's the best way to do this? I suppose I could limit concurrent wireless connections to 20 clients... but more would be nice. EDIT: I should also say that it's purely one-way communication; the smartphone application is only receiving broadcast packets, not sending anything.

• is there a way to run a command before puppet implements a change?

  - by Patrick

  I want to have puppet run a specific command before performing any type of change. I am aware of the prerun_command option in the main puppet.conf, but this is not what I'm looking for. I want the command to only run if something is about to change, not on every puppet run. Here's the scenario. Let's say I have a bunch of web servers behind a load balancer. I then want puppet to update the web site files. But in order to prevent issues where some files have been updated, but other files haven't, and the mixed versions causing problems, I want to take the server out of the load balancer pool. I could write a script which when run will tell the load balancer to remove the box from the pool. Then puppet can do the change, and use postrun_command to put the box back in the pool once complete. But I need a way to run that script to remove the server from the pool. The only solution I can think of is to keep 2 copies of the files on the box. One a staging copy, and when puppet updates that, use a notify action to trigger the removal script, and then copy from staging into the live location. But I was hoping for something a little more generic that would work on any change being performed (upgrading a package, restarting a service, creating a user, anything).

• RAIDs with a lot of spindles - how to safely put to use the "wasted" space

  - by kubanczyk

  I have a fairly large number of RAID arrays (server controllers as well as midrange SAN storage) that all suffer from the same problem: barely enough spindles to keep the peak I/O performance, and tons of unused disk space. I guess it's a universal issue since vendors offer the smallest drives of 300 GB capacity but the random I/O performance hasn't really grown much since the time when the smallest drives were 36 GB. One example is a database that has 300 GB and needs random performance of 3200 IOPS, so it gets 16 disks (4800 GB minus 300 GB and we have 4.5 TB wasted space). Another common example are redo logs for a OLTP database that is sensitive in terms of response time. The redo logs get their own 300 GB mirror, but take 30 GB: 270 GB wasted. What I would like to see is a systematic approach for both Linux and Windows environment. How to set up the space so sysadmin team would be reminded about the risk of hindering the performance of the main db/app? Or, even better, to be protected from that risk? The typical situation that comes to my mind is "oh, I have this very large zip file, where do I uncompress it? Umm let's see the df -h and we figure something out in no time..." I don't put emphasis on strictness of the security (sysadmins are trusted to act in good faith), but on overall simplicity of the approach. For Linux, it would be great to have a filesystem customized to cap I/O rate to a very low level - is this possible?

• Workaround for Dell "Power Supply Not Recognised" issue

  - by Haedrian

  So, I have a Dell Inspirion and the power supply port appears to be damaged. Basically when I plug it in I get a nice popup telling me that it couldn't detect that its a Dell power supply so it won't charge the battery and underclocks the system. It still works for other purposes (that is, giving power) I thought it was the actual power supply cable so I bought a new one, that worked for a while, provided I inserted it at JUST THE RIGHT angle. But now that's not working anymore, so I assume its the part which connects to the computer. The battery charging I can live without, the underclocking I can't. I'd like a way around this issue. Things I've tried: Updating the BIOS Replacing the power supply cable Inserting it at different angles Turning it off and on again Swearing at it Twisting it while inserting it So, is there a workaround somehow? I'd like to avoid taking out my soldering kit and risking permanently damaging expensive equipment if that's allright. I'm hoping for a software solution. Added: The exact model is a Del Inspirion N5010

• XBMC remote control key repeat

  - by Amigable Clark Kant

  Those who have used XBMC with a WiFi remote, such as an Android or iOS device with the official XBMC remotes, have probably seen this at one time or another: your remote stops working, when you press a key, that key is repeated very fast. Sometimes you can break the key repeat loop by pressing that same key again. Sometimes (as this particular morning) you can not. This problem has existed for literally years (it even occurs on the old XBOX only builds) but there seems to be no definite explanation as to what is causing it. I am asking for a workaround. (If you Google, you can find threads were people are ridiculed for bringing up this problem, which is one reason I ask here instead of on the official forums. Also the fact that this problem has persisted for so many years.) I am running, right now, XBMCBuntu Live Eden and the latest official iOS remote. Although, I have seen this problem on all combinations of remotes and XBMC versions I have tried over the years, which are many. (XBMC on Windows, Linux, OSX, remotes on Android and iOS.) Link to bug #136 for the Android remote. It's marked as "fixed" as of client version 636, but the problem is seen again in rev 730. Go figure. There is something fundamentally wrong with how keypresses are sent from the various remotes to XBMC, since this problem is seen across time, XBMC versions and iOS/Android.

• Internet compression proxy for low speed broadband?

  - by user23150

  I live in a rural location, using high-latency wireless off a local ISP's tower. My speed tests vary day to day, but I can get around 1Mb up/down. The problem is, I work with large files, uploading and downloading (HD videos, development software, etc.). It can be painful to wait sometimes. Plus I do some side contract game development, and it can be very difficult to playtest with other developers (200ms ping is a good day for me). Now, obviously it's not going to be easy to solve the latency problem without different wireless hardware. But speedwise, I am wondering if I can use some kind of compression technology on a proxy. For instance, my work computer has full access to a 26Mb down, 10Mb up connection, that is totally unused at night and the weekends. If I could run some kind of compression technology on our server, and use it as a proxy to route to my home computer, I could stand to gain some major speed. I realize that by bogging down a system with compression, I could potentially lose whatever speed gain I had. But the proxy server is a quad core xeon, and the receiving computer is a pretty decent i7 computer, so that shouldn't be a concern. I found http://toonel.net/ but it seems more geared toward very slow narrowband users, like dial-up. Plus, I would prefer to just be able to point my browser to a proxy server, rather then install software on my client machine. EDIT I thought about my question a little more, and realize I am going to need to install software on my client in order to decompress, and possible compress (for uploading). That's not a huge deal.

• Help in recovering partition

  - by goshopedero

  Okay so i had one NTFS partition and i wanted to resize it, but while resizing it with partition magic some error occurred and now i am not able to enter in my partition anymore. I have slackware 13 also and i tried mounting the partition from there but it didn't succeed. One friend of mine came to my house with some live-cd os called backtrack3 and when he booted from cd, he was able to mount the damaged partition - and was able to read/write on it anywhere. I saw my files, they are all there, so nothing's erased just the partition is somehow damaged. But strange thing was that from backtrack we weren't able to mount some of the working partitions of my comp, and we could mount the damaged one. So i am asking for some help here: My files are all there, and i saw them from backtrack. What can i do to fix the partition so it would be usable from windows/slackware again ? Please tell me anything you've got because i have some important data on it. Thank you.

• customer wont provide ssh access - ftp only

  - by Max

  Eh, here is my problem: I am working in a webdevelopment agency (thats a problem but not the real problem, read on). Most of the time I choose the live server myself when creating a new website project. But now the customer already has a "server" (10 GB on a cheapo host!) and the "admin" refuses to give me ssh access to it. But I need to access the server via shell because many files will be transported (need to be able to upload and extract a tar) and I need to insert or create mysql dumps via command line. He argues FTP and phpmyadmin should be enough... as far as I know the webspace was just ordered to host the website, so no security critical apps are running there. How can I either convince the admin to give me the ssh login or tell management that we need our own server? Anyone with similiar experiences? This is really annoying as this is a very small project that should be done fast and now one has to fight in order to just get the work done...

• How can I extract data from Toshiba Satellite with a dead Windows installation?

  - by msanford

  I've got a Toshiba Satellite (unknown model number but bought early 2010) running Windows Vista which throws a kernel error on boot. We don't have the restore/recovery CD any more to restore the Windows partition. I have managed to boot to a Live CD version of Ubuntu 10.10 and have mounted the internal hard drive (which takes nearly 8 minutes). I suspect that the hard drive is malfunctioning, however, because copy tasks of even 30 megs of data to an attached and mounted USB flash drive takes over an hour, and some files are mysteriously inaccessible (not a permissions issue). When browsing folders, it takes many minutes to populate the folder window even with a single tiny file. During the copy tasks, the hard disk sounds like it tries to sleep several times in rapid succession, then continues accessing, it sounds, at full throughput. I initially tried using scp (from the shell) to copy data but I encountered the same local problems. I don't know the S.M.A.R.T. status of the hard disk, either. Is there a more effective way of going about recovering the data on the internal disk, assuming that I can't use a recovery CD and am too cheap to bring it in (for now, at least)?

• Good support to multiple desktops AND multiple monitors in Linux (Ubuntu)?

  - by Somebody still uses you MS-DOS

  I'm starting to have A LOT of opened windows in my machine. Sometimes within a project, I have e-mail/task management/personal e-mail/twitter, and a lot of different opened applications/terminal in my Linux environment. Nowadays I have 4 worspaces: Corporate management (e-mail) and corporate messenger; Work (Documents, Requisites) Dev (Development, All gVim windows, terminal and Firefox for development) Personal (Personal stuff: personal e-mail, delicious, twitter and so on) Sometimes it would be interesting to have different workspaces to projects instead of this configuration I have nowadays that are classes of work (bad name, I know, but I think you got the idea). I'm starting to think about using two monitors: one with Corporate Management, Work and Personal. The second monitor is only the development state: each workspace here is about a project being worked on instead of groups of works like before. A workspace may be implementing different classes for example. My question is: I just want to change to a second monitor using the mouse. I want to still be able to change workspaces in the same monitor using keyboard shortcuts. The keyboard shortcuts wouldn't change monitors, just worskpaces on the same monitor. Does Linux (Ubuntu 10.04 Lucid Lynx) support this envisioned setup? If so, how?

• Java in a browser on Ubuntu

  So I am running an old version of Ubuntu and all of a sudden, my capabilities to run Java in a browser have stopped and it no longer executes properly. Someone else set this up for me, but I believe it's running icedtea plugin 6 and jre 6. What would be the best ways to troubleshoot this? I suppose I could try downloading icedtea 7 and jre 7 (sun or openjdK) and see if that works? Also, in general, is installing icedtea, installing a java runtime environment, and then symlinking something to the plugins directory of your browser the best way to get Java working on most Linux systems? Unfortunately, there are many guides all over the internet offering totally different solutions, but this is probably the most common I've seen (not sure how well it works). My main use is downloading an executing .jnlp files (browsers should open it automatically). Although, I've seen people using "javasw" to run the file outside of a browser. Is this something I could consider doing? I can't seem to find javasw packaged for my version of Ubuntu.

• Laptop keyboard stopped functioning properly

  - by galdikas

  Basically today out of blue my laptop keyboard started acting up. For example I press "s" but I see "`s" on the screen. Some keys don't work at all. And the weird thing is it keeps changing, in a sense that for example in the morning I press "s" and I get "`s", then few hours later "s" works correctly.. but pressing some other key output multiple characters. Then sometimes it spontaneously will start outputting some character onto any input field that is available as soon as I click on it to gain focus. And it will just keep on going and going, as if I keep a button pressed (which I don't). At first I thought this was a virus, but I have a dual boot of Windows 7 and Ubuntu, and I get same problem on both. I even tried to boo live CD, and still had same problem. Anyone had this kind of problem? It's a Toshiba Satellite c660-258. It is around year old, but quite well kept. Never spilled anything on it, or dropped it. And my wireless USB keyboard works perfectly on it (appart from the spontaneous character inputs, which I can stop by hitting NUM LOCK key)
