• New entries on the GRUB

  - by Kiewic

  Hello. I updated my Ubuntu, and after that there were two new lines on my GRUB screen. Ubuntu 9.04, kernel 2.6.28-16-generic Ubuntu 9.04, kernel 2.6.28-16-generic (recovery mode) Ubuntu 9.04, kernel 2.6.28-11-generic Ubuntu 9.04, kernel 2.6.28-11-generic (recovey mode) Ubuntu 9.04, memtest86+ Other operating systems: Microsoft Windows XP Home Edition Do I have two kernels installed? Do the old entries are still useful? Each kernel takes up space? :P And that's not all, when a get into the old version of Ubuntu, the wireless card stops working on any Ubuntu version until I get into Windows and then go back to Ubuntu. Thanks for your help.

• Triple-display setup using AMD drivers

  - by Halik

  I am currently running a dual display setup with nVidia 8800GTS video card, on a Ubuntu 12.10 box. The current setup uses nVidia TwinView to render the image on a 1920x1200 display and 1600x1200 one. I'm planning to add a third, 1280x1024 display to the setup. The change will require me to upgrade my GFX card to one supporting triple displays. I'll probably go with Sapphire Radeon 7770 (FLEX edition, to avoid additional active DP-DVI adapters). Before I invest in new GFX I wanted to ask - how well the AMD drivers will support such a setup. It does not matter whether it's fglrx or the OSS ones. If I remember correctly, when running Fedora on a Radeon x800, I had 'void' areas above and below the working area on my second display. The desktop was rendered in 1920+1280 width and 1200 height (which left 176px of vertical space accessible for my cursor and windows but not displayed on the screen - I'd prefer to avoid that). It may have very well been my misconfiguration back then. Generally, are there any solutions from AMD on par with TwinView? Or is it a non-issue at all? Also, I'm wondering about the usual stuff - hardware h264 decoding support, glitch-free flash support, any issues with Compiz/Unity?

• What is the easiest way to get perfmon counter names into a text file?

  - by Bill Paetzke

  I'd like to create a settings file for my logman command. I expect to have lots of perfmon counters. Is there any easy way to get all the perfmon counters' exact text anywhere? The only thing I thought of was to create a Perfmon Counter Log through the GUI and then export the list of selected counters--but I don't see an export option! I guess I could manually copy what I see on the screen, but that seems inefficient. I'm going to be dealing with tens of counters. Maybe there is a list somewhere? That'd be easier to copy and paste from.

• How to shutdown Windows 8 PC without using mouse?

  - by Gopinath

  Windows 8 sports a re-imagined desktop and tablet user interface with touch friendly Metro looks. One of the major changes in Windows 8 for a common users  is the lack of start menu, with which we got friended for more than a decade. On Windows 8 we would be missing it. As there is no start menu in Windows 8, the way you shutdown a Windows 8 computer is a bit different. To shutdown using Mouse, you need to hover on the top right edge of the screen to open the hidden menu,  go to "Settings"  tab -> "Power" -> Then choose for "Shut down", "Sleep" or "Restart".  That’s a lot of Mouse movement work and if you are a power user then you may not like to do that. How about shutting down the PC using Keyboard? Here are the two ways to shutdown the PC using keyboard Keyboard shortcuts With the help of keyboard shortcuts you can navigate to Power options of Windows 8. Press Win + C to bring the Settings Charm and use Arrows and Enter keys to navigate to access Shutdown menu. This is one of the easiest way to shutdown the PC without using Mouse. Run Command If you don’t like to go through the Setting menu, you can use the traditional Run commands. Press Win + R to open Run dialog and enter the command shutdown -s -t 0 to immediately shutdown the PC.

• I receive the error 'grub-install /dev/sda failed' while attempting to install Ubuntu as the computer's only OS.

  - by Liath

  I am attempting to install Ubuntu on a box which was previously running Windows 7. I have also experienced the dreaded "Unable to install GRUB" error. I am not attempting to dual boot. I have previously run a Windows boot disk and removed all existing partitions. If I run the Ubuntu 12.04 install CD and click install after the config screens, I get the error Executing 'grub-install /dev/sda' failed. This is a fatal error. (It is the same error as this question: Unable to install GRUB) All the questions I've read while looking for a solution are related to dual boot. I'm not interested in dual boot, I'm after a clean out the box Ubuntu install. How can I achieve this? (For my sanity, please use very simple instructions when responding. I don't claim to have any talent either for linux or as a sysadmin) Additional details copied from comments dated: 2012-05-29 ~15:19Z After booting from the CD, clicking Try Ubuntu, and then sudo fdisk /dev/sda I get fdisk: unable to seek on /dev/sda: Invalid argument sudo fdisk /dev/sdb gives Device contains neither a valid DOS partiion table, nor Sun, SGI or OSF disklabel. Building a new DOS disklabel with disk identifier 0x15228d1d. Changes will remain in memory only until you decide to write them. After that of course, the previous content won't be recoverable. Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite). Command (m for help): I should add the Live CD desktop is graphically bad. I've got missing parts of programs and the terminal occasionally reflects to the bottom of the screen. But I can't imagine this is related.

• Disable new window taskbar blinking

  - by muntoo

  You know that annoying orange taskbar blinking? I use Pidgin (among other programs), and I hate it when my taskbar appears with the orange blinking when I am in the middle of something. My taskbar is on auto-hide and set up to the left side of the screen. I cannot click the window I am working to make it overlap the taskbar. (I could disable "Keep taskbar on top of other windows", but it completely hides the taskbar then.) Ideal scenario: Orange light blinks, and I click somewhere (i.e. my maximized window) to hide the taskbar again.

• Dell Vostro 1510 slow boot

  - by pkswatch

  I have an old Dell Vostro 1510 with Ubuntu and Windows 7 on it. When it is switched on, it shows the following message: NO TPM OR TPM HAS ERROR SYSTEM BIOS SHADOWED VIDEO BIOS SHADOWED Then it waits on the same screen for about 70-80 seconds before showing up the grub. I read about tpm problems but did not get anything about shadowed problems. So my guess is tpm isn't the reason for this slow booting (am I right?) But then what is it exactly? Please help..

• DVI to HDMI - displaying bad.

  - by TutorialPoint

  I currently have a computer with a ASUS EAH5770 (ATi Radeon HD 5770) 1GB GDDR5 video card, and 4GB ram, 2.6 GHZ i5 processor. I just switched from a DVI (the blue one) to an HDMI cable. (Bigben Flat cable HDMI 1.3c) I use a Samsung SyncMaster 2032 MW, which has a HDMI input. The weird thing is, that my screen is off-the-corner of the tv (so it's too wide) (1920x1080), and windows icons and text are not displaying well, though 1080p videos in YouTube are looking brilliant, just like pictures. So i think it has something to do with Windows. I already have the ATI Catalyst Control Center with the drivers i received with my video card. I do not currently know how to fix these problems. Do i have to reinstall Windows or so? Or is it (hopefully) easier?

• Internet Explorer defaults to 64-bit version

  - by Tim Long

  My IE8 has suddenly started defaulting to the 64-bit version. I have no idea how or why this has happened, but I suspect it might be linked to the Browser Choice Screen that Microsoft was recently forced to display by EU law. However, many web sites will not display correctly in IE8 x64 (eg. sites that use Adobe Flash or Microsoft Silverlight). I have the 32-bit version of IE pinned to my taskbar and if I launch it manually, everything is fine. But when I click on a URL from another program and IE is not already running, then the 64-bit version gets launched. This really messes with programs like BBC iPlayer which rely heavily on Adbobe Air and Flash. So, how do I get IE8 32-bit version to be the default version again? I've tried using the "default programs" control panel and that doesn;t make any difference (in fact, it doesn't give the choice between x84 and x64 versions, it just lists "internet explorer").

• Add directory to $PATH if it's not already there

  - by Doug Harris

  Has anybody written a bash function to add a directory to $PATH only if it's not already there? I typically add to PATH using something like: export PATH=/usr/local/mysql/bin:$PATH If I construct my PATH in .bash_profile, then it's not read unless the session I'm in is a login session -- which isn't always true. If I construct my PATH in .bashrc, then it runs with each subshell. So if I launch a Terminal window and then run screen and then run a shell script, I get: $ echo $PATH /usr/local/mysql/bin:/usr/local/mysql/bin:/usr/local/mysql/bin:.... I'm going to try building a bash function called add_to_path() which only adds the directory if it's not there. But, if anybody has already written (or found) such a thing, I won't spend the time on it.

  I've Archlinux installed on my laptop Fujitsu Amilo Pi 2*** and I cannot find any log at /var/log that has the StackTrace. The Kernel panics ALWAYS when I try to modify screen brightness.

• 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.

• Sneak Preview - New CodePlex UI

  We have been busy the last several months working to improve the overall experience for the CodePlex community. We have been working through some of the top requested items, such as our big announcement last week enabling Git. Something that is not explicitly on the feature request list are requests to update the web site look and user experience.  As Brian Harry mentioned, the Future of CodePlex is Bright, so it is time to start brightening up the place. Goals As with any sizeable change you need to decide the scope of changes you want to tackle. We decided that we would optimize on incremental improvements verses taking months to get a completely new experience released. Our goals with this user experience work is to refresh the look and feel of the site, introduce new visual elements and set up the site for future structural changes. So this is not the end, just the beginning. Early Views I want to set a few expectations first, these screen shots are not final, and we are still working through the content and final element placement. Feedback is always welcome, just take that in mind as you review the images. New CodePlex Home The navigation changed a good bit on the home page and we have moved the search to a more consistent location across the site.   User Profile Users Home Page The goal was to make it easier to find and take action on common tasks such as creating projects. Project Home Issue Tracker   This should give you a taste of where we are going with the new user experience.     As always we love the feedback, either comment below, find us on Twitter @codeplex or @mgroves84, or create or vote up suggestions.

• Intermittent freezing on a Macbook Pro 7,1

  - by LR0

  I recently installed Ubuntu 12.10 on my MacBook Pro 7, 1. I used to have 11.10 on it. I've encountered a problem were I can boot up and the login screen works flawlessly. When I attempt to log into my account I set up during install it would only show the default wallpaper and the mouse was frozen. In other words it was logging on but froze up. Is what it seems like. When I rebooted I attempted to log into the guest account. I was able to log in and it seemed everything worked so I tried to update everything figuring it may be the problem. After updating and restarting as prompted I tried to login to my account. It still froze up but this time showing "glitched up" (you can see the dock and status bar but they don't look like they should) and still freezes. This is all happening on the guest account to. I was unable to find a similar article on the Internet therefore I am asking; Any thoughts Ubuntu?

• Creating new games on Android and/or iPhone

  - by James Clifton

  I have a succesfull facebook poker game that is running very nicely, now some people have asked if I can port this to other platforms - mainly mobile devices (and I have been asked to make a tablet version, do I really need a seperate version?) I am currently a PHP programmer (and game designer) and I simply dont' have the time to learn Android and other languages - so I have decided to pay third parties to program them (if viable). The information I need to know is what programming language is needed for the following four devices - Android mobile phone, iPhone, iPad and tablets? Can they all run off a central sql database? If they can't then i'm not interested :( Do any of these run FLASH? Have I covered all my main bases here? For example if a person programs for a ANDROID mobile phone is that to much differant to an ANDROID tablet? They will have slightly differant graphics (because the tablet has a greater screen area might as well use it) but do they need to be started from scratch? Same goes for iPhone/iPad, do they really need to be programmed differantly if the only differance is the graphics?

• Unity in 12.10 comes up behind other windows

  - by ams

  I've just upgraded from 12.04 to 12.10. For the most part, everything works fine, but I have a few small problems with Unity, or maybe Compiz. When I hit the Super key, or click on the dash launcher, the dash sometimes comes up behind the other windows on the screen. As you can imagine, this makes it somewhat tricky to use. Once it has started coming up behind, no amount of trying again will convince it to come back to the front. Possibly related, the Alt-Tab switcher doesn't show either. It maybe that there isn't one, or maybe that's behind also? Alt-Tab does switch the windows, but there's no visual indicator. When I hit Super-W, the windows do all do the zoom thing, but it's slow and juddery where it used to be smooth in 12.04. I'm using the standard "radeon" driver, same as before, with a triple-head monitor setup (and that works fine). I've not tried the proprietary drivers as I've previously found the multi-monitor support much weaker than the default driver, but maybe that's the way to go now? Video play fine. Even WebGL seems ok. Do other see this problem? Is it a bug? Or have I just got some left-over config from 12.04 in the way?

• How can I find out what site a popup ad came from?

  - by ændrük

  This is the situation: I've been browsing the web for an hour in pursuit of some bit of technical information and have visited several dozen websites that I don't even remember anymore. I've finally found what I need so I start closing the web browser, only to discover that — aaargh! — there's a popup ad hiding underneath! My blood boils. What insidious website is responsible for this circumvention of my browser's popup blocker? I want to make it pay for its crime. I'll write angry emails. Leave bad reviews. Even block it from my Google search results — yes, that'll show it! But I've reached an impediment. The offending site has already been closed. Is it too late to deduce the advertisement's origin? Or can I somehow un-pop the popup? Here's a test page. With only the popup left on your screen, can you deduce that it was caused by visiting PasteHTML?

• VGA cable casuing resolution issue

  - by LatishS

  Hello, I recently bought a new VGA cable . When connected Windows 7 detects my monitor as a generic plug and play monitor. The resolution goes bad with the screen blurred. This problem disappears when i connect my original VGA cable. Also Windows 7 detects my LG monitor correctly in this case. I am pretty sure it is something to do with the VGA cable but have no idea what could be the possible issue. Any pointers would be very much appreciated.

• Get error (Repair Filesystem) 1 # when I install 4 new Hard drives in RedHat Linux 5 on a Dell PowerEdge 2900

  - by Alos Diallo

  Hi I am using a Dell PowerEdge 2900 running RedHat 5. I had 4 drives in the system using a Raid 5, I purchased and installed 4 more drives keeping the configuration the same. Set up the Vertual disks in PERC 6/i. When I exit out and reboot the system I get the following: fsck.ext3: No such file or dirrectory while trying open /dev/ddb1 [FAILED] ***An error occurred during the file system check. ***Dropping you to a shell; the system will reboot ***when you leave the shell. Then am prompted for the root pw. I enter it and am then prompted with: (Repair filesystem) 1# if I type fdisk -l I get some info on the disk along with: Disk /dev/sdb doesn't contain a valid partition table I am then prompted for (Repair filesystem) 2# If I reboot I am taken to the same screen again. The system was working before this happened. Does anyone know why this is happening and or what I can do to fix it? Thanks

• unable remove/reinstall libxss1:amd

  - by mono

  Whenever I try to install anything (software-center or apt-get) I get an error report stating that libxss1:amd is in a "very bad inconsistent state" (translated from german) and that I should reinstall it. That would not bother me much but I am never sure if the stuff I'm trying will be working in the end. It really resists from being repaired apt-get install, apt-get remove, apt-get -f install, and all the usual suspects - nothing works. It always comes to: dpkg: Fehler beim Bearbeiten von libxss1:amd64 (--configure): Paket ist in einem sehr schlechten inkonsistenten Zustand - Sie sollten es nochmal installieren, bevor Sie die Konfiguration versuchen. Fehler traten auf beim Bearbeiten von: libxss1:amd64 E: Sub-process /usr/bin/dpkg returned an error code (1) I posted the error as is, since my translation might not be exact. But I guess you can figure from my text. I found out that this file is the X screen saver. Maybe I should kill it before handling that file. If thats so, than please tell me how. Thanks for your help, thomas

• What is the pixel clock setting on my monitor actually doing?

  - by codecowboy

  I am experiencing display interference on a dell 24" flat panel monitor.I find that if I adjust the pixel clock settings up or down in the monitor's on-screen menus, the interference goes away for a while. The monitor is attached to a Macbook Pro using a mini display to VGA adapter. I have found that in a different house, I get the interference problem less so it might be related to electricity supply or possibly even ethernet powerline (total guess). What does the pixel clock setting actually do and does this behaviour point to a likely cause of the interference?
