• Dropbox icon dissapears right after login

  - by garvamel

  Even though Dropbox's app indicator dissapearing from the tray area seems like a recurrent enough problem, my issue is a litte different. When I login, I can see the app panel populating, and the dropbox icon does indeed appear (config'd as startup application), but after some other icons show up (bluetooth, battery, etc.) it's gone. It's still running though. I'm guessing it's having issues with staying pinned, and I don't know how to start addressing this problem. I have tried many if not all solutions provided here in the forums for the "icon missing" questions. So far: I've whitelisted everything regarding panel Uninstalled-reinstalled (with and without rebooting in between) Overwritten current installation Purged installation from terminal Installed from Software Center and from .deb file batch deleted every "dropbox" ocurrences from terminal (files and folders) and reinstalled Ran sudo apt-get install libappindicator1, it installed, but didn't solve anything I'm on Ubuntu 12.04 LTS - 64 bits. Any insight would me much appreciated!

• Need an alerting system if my cloning script fails

  - by rahum

  I've configured a nightly rsync to mirror one server to a standby offsite backup server. The total datastore on the primary is 1.5TB. In the course of getting this working, I ran into numerous instabilities with the environment, which I seem to have sorted out, but even though it's now working, I am still nervous. This is intended to be a disaster-scenario standby server, and if disaster strikes and the standby does not have all the proper data synchronized, I'm out of a job. Thus, I want to script a system that will confirm, after each nightly sync, that the destination data matches the source. I realize that rsync does this, but if rsync doesn't complete fully (which was happening during the setup troubleshooting), I need to know. Any suggestions? I'm best with Ruby, if that is relevant for the solution.

• create vmware virtual machine via command line on linux system

  - by tom smith

  evaluating/investigating vmware, and how you create a "virtual machine" using the command line for rhel/centos. basically, i want to be able to create a test virtual machine and then be able to run the VM on another system using the virtual player. so, i'm looking for pointers/articles/instructions that detail what i need (in terms of tools/apps) and the steps needed to accomplish this. i've seen a few articles/sites that discuss creating virtual machines, but they all involve using the GUI. thanks update:: while vmware is the company. there are different tools/apps provided to create a Virtual Machine. Basically, I want to do a test, to ultimately have a Virtual Machine/Image that can be run on a separate server using the vmplayer app I've seen docs that discuss using the GUI to create the VM, but haven't found any (yet) that discuss how to accomplish this using the command line approach. thanks...

• How to delete system default printer forms?

  - by matt wilkie

  On Windows there are system default printer forms which can't be deleted from the Print Server Properties dialog. Is there some other way they can be removed? We are never going to use page sizes like Envelope, B5(JIS), US Std Fanfold, etc. and I'd like to save users (and myself!) from having to scroll through a big long list of noise. Our print servers are Windows Server 2003 if that makes any difference. thanks.

• Create a custom shortcut that types clipboard contents

  - by briankb

  I want to paste my clipboard contents to a remote session such as VNC, IPMI, or Raritan. To accomplish this, I installed xdotool and clip. Then I wrote a simple command that types the clipboard contents: xdotool type "$(xclip -o)" This works if I stay in a terminal window, and type that command myself. It types back my clipboard contents when I run the command. Of course now I want to make this into a hotkey that works in any window. However, if I create a custom shortcut using Keyboard settings, it doesn't work. If I assign a hotkey Alt+K to the shortcut, nothing happens when I press it. If I use Ctrl+K, unexpected behavior occurs to whatever window has focus. e.g. my terminal window size shrinks (it's somewhat amusing, actually). Similar results occur if I save it as a script and call the script, or if I encapsulate the command with sh -c. How can I make practical use of the powerful xdotool type command?

• Ubuntu 14.04 liveusb boot screen graphic errors

  - by user568109

  I am trying to install Ubuntu 14.04 on my Lenovo Y500 laptop. It came preinstalled with Windows 8. I want to install it in a separate partition with a USB drive. I have tried both Unetbootin and universal usb installer. But for some reason the screen after booting is crappy. The screen goes blank after selecting try ubuntu or install. If I try with nomodeset option the screen only displays on a small strip on the top. Which again is split into three. Each seem to be identical. It is not decent enough to begin installation. The graphic card in my laptop is Nvidia GT650M, if it helps. Maybe the problem is related to that. Can anyone help in fixing this error when installing Ubuntu.

• Optimal dir strcuture for keeping millions of files on an ext4 system

  - by Alex Flo

  I need to keep millions of files on an ext4 system. I understand that having a structure with multiple subdirectories is the general accepted solution. I wonder what would be the optimal approach in terms of number of dirs/subdirs. For example I tried a structure like 16/16/16/16 (that is, (sub)directories from 1 to 16) and I found that I am able to move 100K files to this structure in 2m50s. When trying to move 100K files to a 8/8/8/8/8/8 structure it took 11 minutes. So the 16/16/16/16 approach seems to be better but I was wondering if anyone has some empirical experience with an even better dir/subdir distribution.

• Corrupt mysql system tables

  - by psynnott

  I am having issues with the columns_priv table in the mysql system database. I cannot add new users currently. I have tried repairing it using mysqlcheck --auto-repair --all-databases --password but I get the following output: mysql.columns_priv Error : Incorrect file format 'columns_priv' error : Corrupt Is there any other way to repair this table, or how do I go about replacing it with a blank table? What would I lose by doing that? Thank you Edit (Additional Info) mysqld is currently using 100% cpu constantly. Looking at show processlist, I get: mysql> show processlist; +-----+------------------+-----------+-------+---------+------+-------------------+------------------------------------------------------------------------------------------------------+ | Id | User | Host | db | Command | Time | State | Info | +-----+------------------+-----------+-------+---------+------+-------------------+------------------------------------------------------------------------------------------------------+ | 5 | debian-sys-maint | localhost | mysql | Query | 1589 | Opening tables | ALTER TABLE tables_priv MODIFY Column_priv set('Select','Insert','Update','References') COLL | | | 752 | root | localhost | NULL | Query | 0 | NULL | show processlist | +-----+------------------+-----------+-------+---------+------+-------------------+------------------------------------------------------------------------------------------------------+ 2 rows in set (0.00 sec)

• Resizing a System Partition Windows Server 2003 VM (Getting GParted Error)

  - by Dina

  I am getting an error while trying to resize System Partition for Windows 2003 Server (this is a VM on a Hyper-v Windows Server 2008) using GParted Live CD ISO. Followed this tutorial: http://malaysiavm.com/blog/how-to-resize-windows-2003-server-virtual-disk-on-vmware-esx/ and GParted Doc http://gparted.sourceforge.net/larry/resize/resizing.htm (They are very similar) The VM has a Dynamic VHD file, I have already increased it using Hyper-v. GParted doesn't give any clues or details for the error. Just simply errors when trying to grow the partition. Any ideas what I can do? Thanks! Using version of Gparted: gparted-live-0.13.1-2

• How can I efficiently update only the entities that matter in a given frame?

  - by lezebulon

  I'm making a RTS, which can potentially have lots of units in one map (think Age of Empires). I'm looking for a way to update my units. I want to avoid calling a virtual Update() method every frame on every entity. On the other hand, units that are not in view should still be updated and behave "normally." I'm assuming this is a fairly standard question; what would be a way to handle this situation?

• Converting an ancient RH8 system to VMware ESXi

  - by donatello

  I am curious to know what options I have to convert a very old RedHat8 machine to a virtual one on ESXi. Looking at VMware Converter it seems there's an option to login to the RH8 using SSH, and from there it will convert to the ESXi-server. That makes me a bit nervous though, exactly what is happening there? The RH8 machine is slightly critical, and if anything messes up it'll likely result in many hours extra work. :( Another option I thought of was to boot a LiveCD on RH8-system and create a raw "dd dump" of the disk. The similar method is used to restore the image, I boot a LiveCD on the VM in ESXi and use "dd" to write it to disk. Is there any other option I could use? I'm using the cheap version of ESXi, hence I have no access to the Converter BootCD so these rather cumbersome methods is the only I can think of. :)

• Looking for a good free or cheap task tracking system

  - by JWood

  I've finally decided that pen and paper/whiteboards are not up to the job as my workload increases so I'm looking for a good task tracking system. I need something that can track tasks in categories (projects) and allow me to assign priority to each task. I've tried iTeamWork which requires projects to have an end time which is no good for me as at least one of my projects is ongoing. I also tried Teamly which was required tasks to be set to a specific day which is no good as tasks sometimes take more than a day and I would like them organised by priority rather than specific days. Preferably looking for something hosted but I'm happy to install on our servers if it supports PHP/MySQL. Oh, and an iPhone client would be the icing on the cake! Can anyone recommend anything?

• Configure xfce4-screenshooter settings

  - by rubo77

  xfce4-screenshooter is the standard screenshot program in XFCE on Xubuntu. How can I configure the settings about which format it saves the screenshot in and in which folder? I noticed, that my settings I made in shutter also affect the settings of xfce4-screenshooter (but not all). EDIT: The man page sais, there is an -o option to open it with an external program. How can I make this default? Then I could set there an external program, that automatically compresses the screenshot to an emailable size

• Windows 8 gives "system thread exception not handled" after update

  - by Shobhit

  I have a 64-bit dell laptop which I recently upgraded from Windows 7 to Windows 8. Since then, it's creating a havoc in my life. The metro apps are not working; the system crashes once in a while and none of my games are running because I don't have the correct drivers for my graphics card (ATI 5000 series). Some days back, Windows downloaded an update and prompted me to restart. After that day, whenever I log in and fire up my desktop, I get all kinds of blue screen errors. The most common one looks something like this: - SYSTEM_THREAD_EXCEPTION_NOT_HANDLED. Please help me with how I can fix this, optionally how to go back to windows 7. Thanks.

• Restrict Administrators from changing system time - Windows XP machines (no domain)

  I need to write a script that will remove all users under Local Computer Policy > Computer Configuration > Windows Settings > Security Settings > User Rights Assignment > Change the system time from the local group policy (gpedit.msc) on all Windows XP machines. These machines are not on the domain. I DO have a way to distribute and run the script automatically. Can someone point me in the right direction for creating a script like this?

• Mount Docker container contents in host file system

  - by dflemstr

  I want to be able to inspect the contents of a Docker container (read-only). An elegant way of doing this would be to mount the container's contents in a directory. I'm talking about mounting the contents of a container on the host, not about mounting a folder on the host inside a container. I can see that there are two storage drivers in Docker right now: aufs and btrfs. My own Docker install uses btrfs, and browsing to /var/lib/docker/btrfs/subvolumes shows me one directory per Docker container on the system. This is however an implementation detail of Docker and it feels wrong to mount --bind these directories somewhere else. Is there a proper way of doing this, or do I need to patch Docker to support these kinds of mounts?

• Installing VMWare Tools in Windows Server 2008 fails system startup

  - by Hoghweed

  I recently created a vmware virtual machine with windows server 2008 enterprise as Guest. My host is Ubuntu 10.04 on my Lenovo laptop. I fall into a big trouble which makes my created VM unusable after I've installed VMWare Tools. After installing tools I'm able to run the system only in safe mode. After some event manager analysis I found the issue is with drivers installed by vnmware tools. Any one has got the same issue? Is there any good practice for doing that? The configuration of vm machine is the following CPU : 1 RAM : 1020 HD : 40GB Splitted files, SCSI CD : IDE Thanks in advance

• Any good phone system on a Windows Environment ?

  - by Kedare

  Hello, I am looking for a phone system that integrate well with a (almost) 100% Microsoft. I would like something that can integrate with Exchange and Active Directory (in-phone searching/calling by name (is this possible using SIP ?), etc) and if possible something not too expensive (Bye bye Cisco !), what do you recommend me ? I've heard of 3CX as IPBX and Aastra as Phones, are they good for this ? Or do you know something else good at this ? I've also seen some Alcatel IP Phones doing this (search by name, but I think that was a separated address book and not loaded from AD/Exchange) Thank you !

How do I do this, I have Windows 7 and a pile of Linuxes handy so any tool / scripting language is fine.

• Ubuntu 14.04 install fails with Via S3 UniChrome Pro graphics

  - by WizardNo.7

  I am trying to install Ubuntu 14.04 on a Fujitsu Siemens Amilo Pro laptop(it's quite old yes, has about 30GB Hard Drive and I think 192mb of RAM) which currently has Windows XP installed (which I'd like to keep for the time being). I have downloaded the 32-bit Desktop ISO and used unetbootin to create a Live USB for this laptop. When I boot from USB, I arrive at the unetbootin Grey and Blue menu and pick either "Try Ubuntu without installing", or "Install Ubuntu". The menu goes away and an Ubuntu loadscreen showing UBUNTU and four dots which progressively change between white and orange. At about the second color changing cycle a white underscore symbol appears next to the fourth dot and flickers. There is some leftover text from the kernel boot still visible, but there is no graphical desktop. After this I have to hard reboot or shut-down. $ lshw -c video *-display UNCLAIMED description: VGA compatible controller product: CN700/P4M800 Pro/P4M800 CE/VN800 Graphics [S3 UniChrome Pro] Vendor: VIA Technologies, Inc. physical id: 0 bus info: pci@0000:01:00.0 version: 01 width: 32 bits clock: 66MHz capabilities: pm agp agp-2.0 vga_controller bus_master cap_list configuration: latency=64 mingnt=2 resources: memory:f0000000-f3ffffff memory:d1000000-d1ffffff

• Sync, share and backup policy using NAS

  - by Cue

  Trying to come up with a way to keep in sync while sharing and keeping a backup of my music/photos and movies. Currently I have an iMac in Greece and a MBP with me in the UK. As a result I've ended up with 2 iPhoto and iTunes libraries not to mention Documents scattered here and there, user settings etc. I also like to have a backup in case of a drive failure or the need to clean install. It seems that iPhoto and iTunes don't work really well with networked libraries. The way I think about it is to have a NAS where I keep my iTunes and iPhoto library but also rsync daily to my MBP to have a local copy. That way my files are shared across the network as well as act like a backup. In addition I get to have my files wherever I take my MBP but also have the ability to clean install. The tricky part comes from keeping in sync the iMac which is miles away. Again I'm considering a mirror setup (NAS, rsync to the iMac) as well as an rsync between the two NAS. It pretty much resembles the way Dropbox works, sans the requirement to go through their servers but I'm no "superuser" and don't really know if it is even feasible to have such a setup. Looks like there are so many things that can go wrong.
