  • Windows 7 remains powered on when restarting

    - by BombDefused
    I'm running windows 7 x64 on an MSI P67A-GD53 motherboard, in an Antec P280 Super Midi Towercase with a Corsair 650w PSU. I've just installed a second instance of windows 7 x64 on a separate disk (this is to keep my games separate from my work OS). The problem is that it appears now that I cannot restart from either instance of Windows 7. The shut down command, and sleep commands work as expected. When I try to restart, the shutdown happens but the system never reboots. Everything remains powered on, until I hold down the power button to force the power off. Ithink (but am not 100% sure) this has only started since I installed the second OS, and am assuming this has something to do with the motherboard needing to know which OS to run up again? Some other forums I've read suggest that the PSU has a major role in restart and could be at fault. Changing the boot order of the disks in the BIOS does not change anything. Any suggestions greatfully recieved! Update: I now have a reproduceable issue: I think the secondary OS install may have been a red herring. It was when windows tried to reboot during the install that I noticed the issue. After playing around with installing drivers, and rebooting many many times, I have found that it is the OC genie setting on the MSI motherboard that seems to trigger the problem. This makes sense as I only started using the OC genie feature a couple of weeks ago, and probably hadn't used restart in that time. However... simply turning off OC genie does not make the issue go away. I have to turn off OC genie, shutdown, start enter bios, go to the "Save and Exit" menu "Restore Defaults" yes to "Load optimized defaults", which will reset to clear the problem. Now when the PC boots into windows, I can restart as normal (and from the OS on either HDD). I only know how to control the issue, and don't still know the root cause. I'd like to be able to use the OC genie function if anyone can suggest a why I'm seeing this problem. Could it be that I'm drawing too much power when using OC feature?

  • nginx reverse proxy subdomain is redirecting

    - by holtkampw
    So I have a frontend nginx server which will proxy to several other nginx servers (running Passenger for Rails apps). Here's the part of the frontend nginx config in question: server { listen 80; server_name git.domain.com; access_log /server/domain/log/nginx.access.log; error_log /server/domain/log/nginx_error.log debug; location / { proxy_pass http://127.0.0.1:8020/; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_max_temp_file_size 0; client_max_body_size 10m; client_body_buffer_size 128k; proxy_connect_timeout 90; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffer_size 4k; proxy_buffers 4 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; } } server { listen 80; server_name domain.com; access_log /server/domain/log/nginx.access.log; error_log /server/domain/log/nginx_error.log debug; location / { proxy_pass http://127.0.0.1:8000/; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect off; proxy_set_header X_FORWARDED_PROTO https; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } } Finally here's the backend for git.domain.com: server { listen 8020; #server_name localhost; root /server/gitorious/gitorious/public/; passenger_enabled on; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect off; proxy_set_header X_FORWARDED_PROTO https; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } So here's the problem. When I type in git.domain.com, my gitorious install will redirect to domain.com. It works perfect there, but it ignores the subdomain. At first I thought it was the server_name construct. I have tried git.domain.com, domain.com, localhost, and currently none. Any ideas?

  • Is dual-booting an OS more or less secure than running a virtual machine?

    - by Mark
    I run two operating systems on two separate disk partitions on the same physical machine (a modern MacBook Pro). In order to isolate them from each other, I've taken the following steps: Configured /etc/fstab with ro,noauto (read-only, no auto-mount) Fully encrypted each partition with a separate encryption key (committed to memory) Let's assume that a virus infects my first partition unbeknownst to me. I log out of the first partition (which encrypts the volume), and then turn off the machine to clear the RAM. I then un-encrypt and boot into the second partition. Can I be reasonably confident that the virus has not / cannot infect both partitions, or am I playing with fire here? I realize that MBPs don't ship with a TPM, so a boot-loader infection going unnoticed is still a theoretical possibility. However, this risk seems about equal to the risk of the VMWare/VirtualBox Hypervisor being exploited when running a guest OS, especially since the MBP line uses UEFI instead of BIOS. This leads to my question: is the dual-partitioning approach outlined above more or less secure than using a Virtual Machine for isolation of services? Would that change if my computer had a TPM installed? Background: Note that I am of course taking all the usual additional precautions, such as checking for OS software updates daily, not logging in as an Admin user unless absolutely necessary, running real-time antivirus programs on both partitions, running a host-based firewall, monitoring outgoing network connections, etc. My question is really a public check to see if I'm overlooking anything here and try to figure out if my dual-boot scheme actually is more secure than the Virtual Machine route. Most importantly, I'm just looking to learn more about security issues. EDIT #1: As pointed out in the comments, the scenario is a bit on the paranoid side for my particular use-case. But think about people who may be in corporate or government settings and are considering using a Virtual Machine to run services or applications that are considered "high risk". Are they better off using a VM or a dual-boot scenario as I outlined? An answer that effectively weighs any pros/cons to that trade-off is what I'm really looking for in an answer to this post. EDIT #2: This question was partially fueled by debate about whether a Virtual Machine actually protects a host OS at all. Personally, I think it does, but consider this quote from Theo de Raadt on the OpenBSD mailing list: x86 virtualization is about basically placing another nearly full kernel, full of new bugs, on top of a nasty x86 architecture which barely has correct page protection. Then running your operating system on the other side of this brand new pile of shit. You are absolutely deluded, if not stupid, if you think that a worldwide collection of software engineers who can't write operating systems or applications without security holes, can then turn around and suddenly write virtualization layers without security holes. -http://kerneltrap.org/OpenBSD/Virtualization_Security By quoting Theo's argument, I'm not endorsing it. I'm simply pointing out that there are multiple perspectives here, so I'm trying to find out more about the issue.

  • Embedded linux Development learning

    - by user1797375
    I come from a windows background and i am proficient with the .net platform. For work, i need to bring up a custom embedded system platform. We have bought the pandaboard ES as the test platform. The application is to stream images over the wifi. If you think about it, we are building something similar to a netgear router - the only difference being when you log into the device it serves images. Because my background is in windows i am not quite sure how to start off with embedded linux development. in reading through various sites i have come to the conclusion that going to linux as development host is the best option. Can some one point to me in the right direction regarding the set up. I have a windows machine that will be used for development purposes. I can either do a virtual box or setup a partition for linux. But the finer details are what throwing me off..what i need to know is 1) once i install linux what other software do I need - Code blocks, 2) what about toolchain 3) How to debug - through serial port ? 4) Is there a way to send the image built directly to the CF card? Thanks

  • Moving from Ubuntu desktop to Ubuntu Server via SSH

    - by Daniel Elessedil Kjeserud
    So a little while ago I installed regular Ubuntu for a home server, but that gave me a lot of extra packages. What I should have done was to install Ubuntu Server, since I don't even own a screen to connect to it. Does anybody know of a way to convert my Ubuntu machine to a Ubuntu Server machine in one big swoop? It has to be done over SSH, since I don't have a screen to connect to it, like I said. It's currently running 9.10, about to be upgraded to 10.4.

  • iStack for iPad

    - by Jonathan
    The below image is the current, and hopefully final, look of the front screen, the app will remember which stack site you have chosen so the user will only see this screen the first time, but they can always go back and change it. The red bar is only there when a new site is added (the StackOverflow is just a test as no site has been added since I implemented this) and can be gotten rid of by tapping the X on the right side (which isn't in the screenshot). Each column now has an edit button where the sites can be rearranged and moved from favourites to non favourites and this is persistent between app launches, moving a site in one column moves it in all of them. I've removed site icons in order to put them in properly so they load lazily and theres no UI freezing. Printing Functionality all implemented and working, thanks to systempuntoout's stackprinter.com works with AirPrint, which means this app will be iOS 4.2 minimum. Current features: 3 columns Email link to question, open in safari and copy link actions History for both questions and sites visited In app notification (red bar at the top) when a new site makes it into beta. StackPrinter in the app, without needing safari, and AirPrint functionality. Facebook Intergration Planned: Local Favourites Watching (a list of questions your watching, like short term favourites, with eventually push notifications) Web service to access local favourites and watches on non-iPad devices. Twitter integration. Safari bookmarklet to open question in iStack from safari In app notification for when site progresses from beta to normal. In app notification history

  • In Windows 8, how do you disable the unlock password for Microsoft Accounts?

    - by Huckle
    In Windows 8, in the scenario where there is a single user that has a Microsoft Account (i.e., they have created their account via a Microsoft email address) how does one disable the password prompt when unlocking the screen? The Windows 7 analogy would be to disable the screensaver password prompt. I can do this on a "local" account (one not backed by Microsoft) but the setting seems to have no effect on connected accounts. To replicate: create an account using [email protected] or [email protected] Lock the screen with WinKey+L Attempt to unlock, by clicking the mouse, without entering a password.

  • x11vnc is slow, but using only 10% of available bandwidth

    - by mmm
    I am using x11vnc over 15Mbit/s network with 20ms latency. When the screen is changing a lot x11vnc is slow - for example when I switch a tab in a browser, it takes almost two seconds until the view is fully redrawn. The strange thing is that max connection speed of x11vnc is even during slow redrawing only about 10% of the available bandwidth. Why is x11vnc not using available bandwidth to speed the redrawing up? For example scp is using 100% of available bandwidth without problems. How can I identify what is the bottleneck for x11vnc on my system? So far I think: 10% network usage = network is not a bottleneck fb read rate: 601 MB/sec = reading fb is not a bottleneck Any ideas how can I further profile x11vnc and find out what is causing a slowdown? For example is there any switch for x11vnc to show how much data it is handling and how long it takes to grab a screen, process and compress it and send it over the network?

  • Cannot boot from USB on my Mac mini

    - by Thai Tran
    Two weeks ago I installed OSX 10.8 on my Mac mini. After that, my system started to hang a lot, so I tried to erase it and install OSX 10.7 again. I used carbon Copy Cloner to make the bootable USB and it can load successfully on another Macbook. However, on my Mac mini, when I press on the option button to select the USB, it loads the white screen with a ban symbol at the center of the screen. After a moment, my machine automatically shuts down. Does anyone know how to solve this problem? Edit: this is exactly the problem I have now http://forums.macrumors.com/archive/index.php/t-1207168.html Update 1: the hdd seems ok (from disk utility). I restored the booting partition by disk utility (drag the dmg file to that partition). After restarting and using that partition to boot, prohibited symbol is still there

    - by Pinal Dave
    Here is the list of selected articles of SQLAuthority.com across all these years. Instead of just listing all the articles I have selected a few of my most favorite articles and have listed them here with additional notes below it. Let me know which one of the following is your favorite article from memory lane. 2007 FQL – Facebook Query Language Facebook list following advantages of FQL: Condensed XML reduces bandwidth and parsing costs. More complex requests can reduce the number of requests necessary. Provides a single consistent, unified interface for all of your data. It’s fun! UDF – Get the Day of the Week Function The day of the week can be retrieved in SQL Server by using the DatePart function. The value returned by the function is between 1 (Sunday) and 7 (Saturday). To convert this to a string representing the day of the week, use a CASE statement. UDF – Function to Get Previous And Next Work Day – Exclude Saturday and Sunday While reading ColdFusion blog of Ben Nadel Getting the Previous Day In ColdFusion, Excluding Saturday And Sunday, I realize that I use similar function on my SQL Server Database. This function excludes the Weekends (Saturday and Sunday), and it gets previous as well as next work day.

DBCC SHRINKFILE Takes Long Time to Run If you are DBA who are involved with Database Maintenance and file group maintenance, you must have experience that many times DBCC SHRINKFILE operations takes a long time but any other operations with Database are relatively quicker. mssqlsystemresource – Resource Database The purpose of resource database is to facilitates upgrading to the new version of SQL Server without any hassle. In previous versions whenever version of SQL Server was upgraded all the previous version system objects needs to be dropped and new version system objects to be created. 2009 Puzzle – Write Script to Generate Primary Key and Foreign Key In SQL Server Management Studio (SSMS), there is no option to script all the keys. If one is required to script keys they will have to manually script each key one at a time. If database has many tables, generating one key at a time can be a very intricate task. I want to throw a question to all of you if any of you have scripts for the same purpose. Maximizing View of SQL Server Management Studio – Full Screen – New Screen I had explained the following two different methods: 1) Open Results in Separate Tab - This is a very interesting method as result pan shows up in a different tab instead of the splitting screen horizontally. 2) Open SSMS in Full Screen - This works always and to its best. Not many people are aware of this method; hence, very few people use it to enhance performance. 2010 Find Queries using Parallelism from Cached Plan T-SQL script gets all the queries and their execution plan where parallelism operations are kicked up.

SQL SERVER – Interview Questions and Answers – Guest Post by Malathi Mahadevan – Day 26 of 31 Malachi had asked a simple question which has several answers. Each answer makes you think and ponder about the reality of the IT world. Look at the simple question – ‘What is the toughest challenge you have faced in your present job and how did you handle it’? and its various answers. Each answer has its own story. SQL SERVER – Interview Questions and Answers – Guest Post by Rick Morelan – Day 27 of 31 Rick Morelan of Joes2Pros has written an excellent blog post on the subject how to find top N values. Most people are fully aware of how the TOP keyword works with a SELECT statement. After years preparing so many students to pass the SQL Certification I noticed they were pretty well prepared for job interviews too. Yes, they would do well in the interview but not great. There seemed to be a few questions that would come up repeatedly for almost everyone. Rick addresses similar questions in his lucid writing skills. 2012 Observation of Top with Index and Order of Resultset SQL Server has lots of things to learn and share. It is amazing to see how people evaluate and understand different techniques and styles differently when implementing. The real reason may be absolutely different but we may blame something totally different for the incorrect results. Read the blog post to learn more. How do I Record Video and Webcast How to Convert Hex to Decimal or INT Earlier I asked regarding a question about how to convert Hex to Decimal. I promised that I will post an answer with Due Credit to the author but never got around to post a blog post around it. Read the original post over here SQL SERVER – Question – How to Convert Hex to Decimal. Query to Get Unique Distinct Data Based on Condition – Eliminate Duplicate Data from Resultset The natural reaction will be to suggest DISTINCT or GROUP BY. However, not all the questions can be solved by DISTINCT or GROUP BY. Let us see the following example, where a user wanted only latest records to be displayed. Let us see the example to understand further.

  • FreeBSD 8.2 + Apache 2.2 + mod_auth_pam2: unable to authenticate

    - by zneak
    I've installed Apache 2.2 and mod_auth_pam2 from ports, but I can't get local UNIX authentication to work. When I access the protected part of my local website, I do get the authentication request, and with pam_permit.so, it works. However, when I change pam_permit.so to the real thing, pam_unix.so, I get this message in httpd-error.log: [error] PAM: user 'foo' - not authenticated: authentication error This is the relevant part of my Apache config, though I don't think it's the problem as it works with pam_permit.so: <Location /foo> AuthBasicAuthoritative Off AuthPAM_Enabled on AuthPAM_FallThrough off AuthType Basic AuthName "Secret place" Require valid-user </Location> This is my /etc/pam.d/httpd, though I don't think it's the problem either, since it works with pam_permit.so: auth required pam_unix.so account required pam_unix.so So what am I missing? What does it take to have pam_unix.so work for httpd under FreeBSD?

  • What does the number after 7-zip's -m switch mean?

    - by AndreKR
    7-zip has a command line switch to set the compression method, -m followed by a number, e.g. -m0=LZMA. What does the number (0 in the example) mean? Different numbers produce slightly different compression results and performance: time 7z -m0=LZMA -mx=9 -ms=on -mmt=off real 0m2.292s user 0m2.190s sys 0m0.080s time 7z -m1=LZMA -mx=9 -ms=on -mmt=off real 0m2.405s user 0m3.240s sys 0m0.070s time 7z -m0=LZMA -mx=9 -ms=on -mmt=on real 0m1.038s user 0m1.920s sys 0m0.150s time 7z -m1=LZMA -mx=9 -ms=on -mmt=on real 0m1.187s user 0m2.800s sys 0m0.130s

  • Acer aspire 5520 power light blinks no boot

    - by Shawn Mclean
    My laptop was working fine last night, I hibernated it and went to sleep. Got up, pressed the power button. The power light comes on for 4 seconds and the hdd light blinked a few times, then it turned off for a second then repeats the process. The only way to stop this process/power down is to remove the AC and take out the battery. It does not even reach a boot screen, nothing shows up on the screen, fan does not start. People on this forum has the same problem but they suggest to put the laptop in a oven and heat it (reflow). What could be the problem? Is there another solution other than a reflow? I dont feel like putting my motherboard in the oven.

  • Xubuntu login hangs after Cancel Button click

    - by akester
    I'm running Xubuntu 12.04 (I installed using the alternative installer.) running in Virtaulbox 4.1.20 My issue is with the login screen (lightdm-gtk-greeter). It usually runs just fine, and allows users to log in and out but it will hang if the user presses the cancel button. The interface is still working (ie, shutdown menu is still available, I can switch to a different tty) but the username or password field (depending on when the button is hit) is disabled. Restarting lightdm will reset the screen, but the problem still exists. The issue is only with the cancel button. The login, session, and language buttons/menus as well as the accessibility and shutdown menu appear to work normally. I've modified some of the config files for lighdm-gtk-greeter, specifically /etc/lightdm/lighdm-gtk-greeter.conf to change the background image and /etc/lightdm/lightdm.conf to disable the user list. I did not check to see if the error existed before the changes took place. The changes have been restored the default settings but the problem persists. Here is the output of /var/log/lightdm/lightdm.log when the screen is hung: [+0.00s] DEBUG: Logging to /var/log/lightdm/lightdm.log [+0.00s] DEBUG: Starting Light Display Manager 1.2.1, UID=0 PID=2072 [+0.00s] DEBUG: Loaded configuration from /etc/lightdm/lightdm.conf [+0.00s] DEBUG: Using D-Bus name org.freedesktop.DisplayManager [+0.00s] DEBUG: Registered seat module xlocal [+0.00s] DEBUG: Registered seat module xremote [+0.00s] DEBUG: Adding default seat [+0.00s] DEBUG: Starting seat [+0.00s] DEBUG: Starting new display for greeter [+0.00s] DEBUG: Starting local X display [+0.02s] DEBUG: Using VT 7 [+0.02s] DEBUG: Activating VT 7 [+0.03s] DEBUG: Logging to /var/log/lightdm/x-0.log [+0.04s] DEBUG: Writing X server authority to /var/run/lightdm/root/:0 [+0.04s] DEBUG: Launching X Server [+0.05s] DEBUG: Launching process 2078: /usr/bin/X :0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch [+0.05s] DEBUG: Waiting for ready signal from X server :0 [+0.05s] DEBUG: Acquired bus name org.freedesktop.DisplayManager [+0.05s] DEBUG: Registering seat with bus path /org/freedesktop/DisplayManager/Seat0 [+0.28s] DEBUG: Got signal 10 from process 2078 [+0.28s] DEBUG: Got signal from X server :0 [+0.28s] DEBUG: Connecting to XServer :0 [+0.29s] DEBUG: Starting greeter [+0.29s] DEBUG: Started session 2082 with service 'lightdm', username 'lightdm' [+0.36s] DEBUG: Session 2082 authentication complete with return value 0: Success [+0.36s] DEBUG: Greeter authorized [+0.36s] DEBUG: Logging to /var/log/lightdm/x-0-greeter.log [+0.36s] DEBUG: Session 2082 running command /usr/lib/lightdm/lightdm-greeter-session /usr/sbin/lightdm-gtk-greeter [+0.58s] DEBUG: Greeter connected version=1.2.1 [+0.58s] DEBUG: Greeter connected, display is ready [+0.58s] DEBUG: New display ready, switching to it [+0.58s] DEBUG: Activating VT 7 [+1.04s] DEBUG: Greeter start authentication for andrew [+1.04s] DEBUG: Started session 2137 with service 'lightdm', username 'andrew' [+1.09s] DEBUG: Session 2137 got 1 message(s) from PAM [+1.09s] DEBUG: Prompt greeter with 1 message(s) [+17.24s] DEBUG: Cancel authentication [+17.24s] DEBUG: Session 2137: Sending SIGTERM

  • SQL Monitor Alerts in Outlook Without Configuring Email Settings

    - by Fatherjack
    SQL Monitor is a Red Gate tool that I have a long history with and I have worked closely with the development team from a time before it was called SQL Monitor. It is with that history in mind I am a little disappointed in myself that I have only just found out about a pretty cool feature. Out of the box SQL Monitor keeps itself to itself, it busily goes about watching over your servers, noting down when things look suspicious, change drastically or are just out and out wrong. You have to go into the settings and provide email details (SMTP server, account details etc.) before it starts getting at all intrusive with warning and alerts on the condition of your servers. However, it was after installing the most recent version that I was going through the application screen by screen looking for new and interesting changes that I noticed something that had avoided my attention. On the Alerts tab there is an option in the left hand menu. I don’t know how long ago it appeared or why I have never explored it previously but it appears that you can see your Alerts in the format of an RSS feed. Now when you click that link you are taken to a page that is the raw RSS XML – not too interesting but clearly you can use this in an RSS aggregator. Such as Outlook. Note the URL in the newly opened page take it with you into Outlook. For me it is in the form of http://SQLMonitorServerName/Alerts/Inbox/Feed. Again, this is something that I have only recently noticed – Outlook can aggregate RSS feeds. Down below the Inbox, Drafts folders etc, one up from the bottom is RSS Feeds. If you right click that and choose to Add a feed then you can supply the URL for SQL Monitor Alerts: And there you have it, your SQL Monitor Alerts available in Outlook where you can keep an eye on the number of unread items and pick them off at your convenience.

  • Hyper-V 2012 and VM web server http

    - by Syrus
    I have a a few windows 2008 R2 Datacenter machines and a few windows 2012 Datacenter machines. I was runnin RedHat 6.2 VM on 2008 and all my other servers could access it over http until I put a VM up on 2012. No mater what I have done, (turned off selinux, firewall, iptables), on both RedHat servers has allowed them to pass http traffic. They can ping each other and ssh to each other but not http. I tried turning off the windows firewalls to, but no joy. I then moved the RedHat VM to the 2012 server and now the two RedHat VM's can http to each other, but none of the other vm's on other 2012 and 2008 servers can communicate over http. Anyone have some insight?

  • SQL SERVER – 2011 – Multi-Monitor SSMS Windows

    - by pinaldave
    I have a dual screen arrangement at my home system. I love it because it’s very convenient. When I am working with SQL Server 2008 R2 or any earlier versions, I would want to use both of the Monitor so I open two separate SQL Server Management Studio and work along with it. I have no complaints with my system, at all. I am totally fine with it. However, sometimes I face small issues, like when I just want a small code open in a separate window but I do not want the windows to take over the whole of another window. But then again, I am already used to this current system. Recently when I was working with SQL Server 2011 ‘Denali’ CTP1, I dragged one of the windows by accident, and suddenly it magically appeared out of its ‘Shell’ of SSMS and was appearing on a separate monitor. I played around a bit and figured out that SSMS now supports multi-monitor (or multi screen) support with single SSMS instance. We can now drag out and drag in any window and resize them at any size. Fantastic! If you are multi-monitor user, I am sure you will like this feature. This leads me to ask you question? Do you use multi-monitor system while working with SQL Server? Leave a quick comment.

  • Why do things change between using a LiveCD/LiveUSB and installing Ubuntu?

    - by ahow628
    Here have been a couple of weird experiences I've had with a Ubuntu LiveCD or LiveUSB: 1) I had one of the original Chromebooks (CR-48). I ended up wiping ChromeOS and installing only Ubuntu 12.04.0 just after it came out. It worked like a charm. About a year later, I broke something and reinstalled Ubuntu using 12.04.3 on a LiveUSB. The LiveUSB worked perfectly - screen resolution, wifi, trackpad all worked fine. I installed it (once installing updates, once stock from the USB drive) and both times screen resolution, wifi, and trackpad all broke. I ended up downloading 12.04.0 and installing it then upgrading to 12.04.3 after the fact and everything worked perfectly once again. 2) I purchased a Toshiba Portege z935 and the LiveUSB worked perfectly, namely the wifi. After install, wifi was extremely slow and basically couldn't load any pages. The answer was that Bluetooth conflicted somehow with wifi and Bluetooth had to be disabled to get wifi to work. Yet both could be enabled in the LiveUSB version, no problem. So my question is, why does this happen? Why does everything work perfectly from the LiveUSB version but then get broken when installed on the system? Is there a different way to install Ubuntu that would allow things to be installed over exactly as they were on the LiveUSB version (drivers, settings, etc)? Are there assumptions that the install makes that I could override somehow?

  • X locks up with konqueror on comics.com

    - by retracile
    If I browse to comics.com using konqueror under KDE on Fedora 11, X will, after a delay, lock up. The mouse will move, but no keyboard input is recognized, and the screen does not react to the mouse passing over objects on screen. I am able to ssh into the machine and issue shutdown -r now and have that work. The machine is a Dell XPS M1330 with Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c), and Fedora 11 is fully updated. Visiting the same site in Firefox does not cause a lockup. I am booting with nomodeset since it won't boot into X otherwise. I tried the other two accel options: EXA (still locks up) and XAA (X won't start). Any suggestions on how I can debug this? bugzilla

  • How can I display and log PHP errors on IIS7?

    - by Ben
    We're running PHP 5.2.5 on an IIS 7 Server and we're having problems making PHP errors visible... At the moment whenever we have a PHP error the server sends back a 500 error with the message "The page cannot be displayed because an internal server error has occurred." This might be a good setting for production websites but it's rather annoying on a development server... ;-) I have tried configuring php.ini to display errors to the screen as well as log them to a specific folder but it seems that the Server catches all errors before and prevents and handling by PHP... Does someone know what we have to do to make IIS display PHP errors on screen? Any links, tipps or tutorials on the subject would be appreciated!
