• Windows 7 Blank Screen on Boot / Login

  - by Greg

  I have a new system that's having a few problems... sometimes (seems to be when the PC is cold, i.e. has been switched off for a while, though that could be my imagination) I get a blank blue screen when I boot up. The system boots normally and auto-logs-in. The desktop loads and I'm even able to launch applications, but then everything disappears and the screen goes to the default windows desktop blue colour (not the desktop image, just a plain blue with no mouse cursor). At this point the machine completely locks up - I'm unable to even toggle Num Lock and have to hold in the power button for 5 seconds to kill it. Interestingly if I manage to launch some applications before it goes blank, they will usually crash... sometimes explorer.exe will crash too. When I reboot, the system is fine and stable. I've installed the latest graphics drivers and run memtest86+ for 6 passes (and counting) with no errors. The system specs are: CPU: Intel I7 2.66 @ 3.4GHz RAM: 6GB (3 * 2GB DDR3) HDD: 128GB Crucial M225 SSD Motherboard: Gigabyte EX58-UD3R Gfx: ATI Radeon Sapphire 5870 1GB Note: There are a few similar questions but I haven't found one that matches my symptoms

• HTML tabindex: Put some links last without complete enumeration

  - by Emanuel Berg

  I know I can use the HTML anchor attribute tabindex to set the tabindex of links, i.e., in what order they get focused when the user hits Tab (or Shift-Tab). But, I have a home page with tons of links, and to enumerate all those is a lot of work. The actual case is, I have four image links that by default gets index 1, 2, 3, and 4 (well, the behavior is equivalent, at least). But, I'd much rather have the first non-image link as number 1. Check it out here and you'll understand immediately. I tried to give the first non-image link (the link I desire to have tabindex 1) - I tried to give it tabindex 1 explicitly, hoping that it would cascade from there, but it didn't (i.e., the first image link got implicit tabindex 2). I also tried to give the image links ridiculously high tabindexes, but that didn't work: as the other links didn't have tabindexes at all, those highs were still "first". As a last resort (the solution currently employed) I gave the image links all tabindex -1. That makes for logical tabbing, but, it is suboptimal, as those image links are excluded from the tab loop - a user tabbing away will probably never realize that the images are clickable. I'd like them to be reachable with tabbing, but last, after all the ordinary links. If you wonder why I'm so determined to achieve this, it has to do with my own finger habits: I almost exclusively search for links, tab back, tab forth, etc., and very seldom using the mouse. Note: I'll accept a script to change the actual HTML for a complete enumeration, if you convince me there is no "set" way to solve this problem.

• X11 performance problem after upgrading from Centos3 to Centos5 with an ATI Rage XL

  - by Marcelo Santos

  After upgrading a computer from Centos3 to Centos5 an application that does a lot of scrolling took a very high performance hit. top tells me that X is using a lot of CPU and that was not happening before. The machine has an ATI Rage XL with 8MB and X is using the ati driver as there is no proprietary ATI driver for this board on linux.

• Suggestions for Windows 8 migration [closed]

  - by Big Endian

  I'm thinking of migrating to Windows 8. At first I hated it, but I'm pretty sure the Windows 8 model is the future, and I don't particularly want to end up hating the future like my parents, frustrated and bewildered by anything past Windows XP. I'm currently running Windows 7 and my system has been accumulating some problems. It's probably an accumulation of issues from installing too much software, changing firewall settings, installing Ubuntu alongside Windows, and... well I'm not sure, but my computer has been buggy in unexpected ways lately (freezing and unfreezing, display driver crashing and recovering, and what I call "deep freeze/thaw cycle" where the mouse won't even move for a while). I'm good at solving computer problems, but I can't seem to get to the root of these and my best idea for fixing them is making sure I've backed up every file then re-installing the entire OS. Luckily for me, a new OS is just around the corner so this would be a good time to get two things out of the way at once. The problem I see is that the upgrade options I see are all "seamless". I don't want a seamless upgrade. I want to wipe the slate clean and start all over. Does this mean I will have to buy a full, new copy of Windows 8 rather than one of the cheaper upgrading options? Or does it not make since for me to go to Windows 8 given that I have a laptop, not a tablet? Maybe I should just re-install Windows 7, or even call good enough good enough, try to eliminate the bugs, and start with a fresh slate in 2-3 years after this computer eventually dies entirely from (inevitable) hardware failure. What would be the advantages or disadvantages and costs of each option, how would I go about upgrading to Windows 8 if that's the option I choose, and what is your personal opinion about my situation?

• How can I run Gnome or KDE locally in Cygwin?

  - by John Peter Thompson Garcés

  Apparently it is possible to do this using cygwin ports, as can be seen in screenshots. I followed this how-to to get apt-cygports set up, and I used it to install gnome-session. This how-to supposedly gives the commands needed to run Gnome or KDE, but whenever I try to run Gnome, a blank X-window pops up and then quickly disappears. Here is the terminal output: $ startx /usr/bin/dbus-launch gnome-session xauth: file /home/jpthomps/.serverauth.4168 does not exist Welcome to the XWin X Server Vendor: The Cygwin/X Project Release: 1.10.3.0 OS: Windows 7 Service Pack 1 [Windows NT 6.1 build 7601] (WoW64) Package: version 1.10.3-12 built 2011-08-22 XWin was started with the following command line: /usr/bin/X :0 -auth /home/jpthomps/.serverauth.4168 (II) xorg.conf is not supported (II) See http://x.cygwin.com/docs/faq/cygwin-x-faq.html for more information LoadPreferences: /home/jpthomps/.XWinrc not found LoadPreferences: Loading /etc/X11/system.XWinrc LoadPreferences: Done parsing the configuration file... winDetectSupportedEngines - DirectDraw installed, allowing ShadowDD winDetectSupportedEngines - Windows NT, allowing PrimaryDD winDetectSupportedEngines - DirectDraw4 installed, allowing ShadowDDNL winDetectSupportedEngines - Returning, supported engines 0000001f winSetEngine - Using Shadow DirectDraw NonLocking winScreenInit - Using Windows display depth of 32 bits per pixel winFinishScreenInitFB - Masks: 00ff0000 0000ff00 000000ff Screen 0 added at virtual desktop coordinate (0,0).

• Does AMD Cool n Quiet Slow Down Your System?

  - by Software Monkey

  I discovered today that having AMD Cool n Quiet enabled in my BIOS appears to be slowing down my Windows XP SP2 system by about 29% on memory & CPU intensive workloads. I was wondering if (a) anyone else had encountered this, (b) anyone can offer an explanation, (c) there are any negatives I need to be aware of if I keep AMD CnQ disabled. With some superficial testing so far, I don't immediately notice any difference with CnQ off (other than the performance being what I expected from this new hardware). It seems to ramp up the CPU fan a little bit as my program maxes out 1 core, but that's the same as with CnQ on. And when I let the system idle the CPU fan slows down and the systems as quiet as a mouse (after years of 6 small fans churning like they want to go into orbit it's nice to again have a system where I can hear the HDDs seeking). Bonus question: Does CnQ cause issues with system stability? I ask because the reason I disabled it was because I have had a few freezes and 1 spontaneous reboot with my new hardware.

• Selective Pointer device remapping in linux

  - by user6368

  I just got an HP 2710p (hp tablet, with digitizer), and I've played around with linux for a while now, and thought I would go ahead and install it. Everything works fine, excepting normal tablet functions, which is to be expected. I'm working on the screen rotation, and there are on-screen keyboards, etc, but I'm having issues with the stylus. I can tap and left click with the stylus as normal, but the side button (which in windows functions as a right mouse button) appears as a 'button 2' to xev (a middle/scroll wheel button). I can switch 'button 2' and 'button 3' universally using xmodmap, but I'd like to do so exclusively for stylus so I don't screw up regular pointing devices. Altering xorg.conf (which is surprisingly bare) with the recommended sections (adding sections for each of the stylus buttons) does nothing. I'm running crunchbang, which is an ubuntu/debian varient with openbox as the windows manager. Thanks Also, as a seperate note, does anybody know how to detect when I rotate and/or latch the lid shut? I was thinking maybe I could run a script to switch the buttons when I close it, but I can't find any information.

• Thin client - cloud machine - to run via iPad, iPhone, most Androids etc

  - by Carl Lindberg

  I'm tired of having a laptop macbook that breaks down or having files that I need to sync via dropbox etc all the time via the machines to different OS installations. It sucks. I want a thin client where I can login on any machine - my iPhone, PC desktop, iPad etc to one running machine. I would like to replace a modernly powerful desktop iMac with a thin client running via my iPad. I will connect the iPad with a keyboard/mouse too so you get the idea. But I want to be able to use some of the Android phones as well (I guess most Android phones today has a good enough performance/resolution etc to run a thin client). Of course it has to be able to have input/output in sound. Printing can be solved by PDF/emailing etc - so no direct communication to the printer ports to USB etc is necessary. Is there such a service today? It should cost somewhere under something like $40/ month. I will run stuff like CPU heavy duty ableton for music production, xCode for making iOS apps, some games etc. And on the thin client also run virtual machines. VM of Ubuntu and Windows.

• Misconfigured external monitor on Mac OS X Snow Leopard 10.6.3

  - by Mike

  I have an external monitor (specifically, an HDTV) hooked up to my 2.53GHz 13" macbook pro. This display works fine and I use it with my mac in clamshell mode (eg. with an external keyboard/mouse and the laptop closed and the built-in mac screen turned off) My Mac has multiple users on it. For User A I can use the mac with the external monitor in both clamshell and dual-monitor setups. For User B, I can use the monitor in a dual-monitor setup, but whenever I switch to clamshell mode the Mac switches to an incorrect output resolution or frequency setting that my HDTV doesn't recognize, resulting in a blank screen and a message about Unsupported Resolution. Chances are I did this to myself by misconfiguring my display settings at some point in the past, but I have no idea how to undo it. I (obviously) can't seen the display to change the settings when it's borked. I can see the display settings if I switch to Dual-monitor mode, but those settings only affect the dual monitor setup; no matter how I change the settings in dual-monitor mode, the clamshell mode setup remains borked. How can I dig myself out of this hole?

• Spots appear in a rectangle area on screen, ubuntu gnome 13.04, nvidia driver

  - by frozen-flame

  I am using Ubuntu Gnome 13.04 with nvidia-310 driver installed. My GPU is GeForce GTX650. Strange spots freqently appear on screen, with following traits: Spots are restricted in one or two rectangle areas at any instant. When typing, the pattern of spots change. Possibly increase, or all disappear when one key pressed. Mouse movement also influences. This problem last within one boot. The only way can I get rid of this problem is to reboot. It can be detected as soon as entering desktop if it appears. Simultaneously, the "power off" option is lost in the top-right menu of Gnome3. Never such problem when using windows 7 on the same computer, neither ubuntu with Nouveou driver. Seldomly, half of the screen become black. I googled a lot. Similar conditions are described, but no confirmed solution. Uninstall-r einstall strategy does not work. Any clue solving this will be appeciated.

• Looking for an application that scrolls or pans netbook screens running Windows

  - by Rob

  I'm looking for a Windows 7 and XP compatible Windows desktop panning/scrolling tool. This is to solve a problem where some applications for example MSN have settings/preference Windows that are not resizeable. I have a Netbook with a small maximum screen resolution e.g. 1024x600. The fixed non-resizeable windows are too large for this display screen size so I cannot see all of the items on these windows, particularly the OK button to save settings. What I would like is a desktop scrolling/panning tool where if I move my mouse pointer to any edge of the display, it pans to show the region of the too-large-fixed window that I could not see. I use a Samsung N110 and Toshiba NB100 netbooks. I'm looking for: A general program that provides desktop panning/scrolling/expanded resolution to allow all regions of a non-resizeable fixed window Preferably a non-graphics hardware specific program but will accept a solution that works with both the above machines I'm NOT looking for (i.e. unsatisfactory answers others have asked that I've already searched and found): Advice on what programs to use that DON'T have the problem of fixed windows Alternative operating system solutions Plugging in an external monitor with larger resolution - I use this option but I need a solution when one is not available, e.g. while travelling etc Advice about not using small screen netbooks - I enjoy the compact convenience of them Advice about change the dpi settings in the Control Panel Display settings Advice about guesswork with the tab key to move the focus the off-screen item I cannot see Thank you in advance.

• Mac: window manager frozen, have ssh access

  - by Bernd

  I have a Mac which regularly runs into a problem. The user interface stops reponding, showing a "frozen" user interface. The mouse is still moving but clicking does not trigger anything. This happens about once a week. Solution so far is to force switch-off the Mac and reboot it. I have ssh root access to the Mac. Killing (kill -9) the active application has no visible impact on what is shown on the screen. Any ideas on how to diagnose this? Is there a way to restart the window manager from the ssh shell? Killing /System/Library/Frameworks/ApplicationServices.framework/Frameworks/CoreGraphics.framework/Resources/WindowServer seems not to be possible. The Mac is an early 2008 iMac and runs Lion with latest updates. /Library/Logs/DiagnosticReports is empty. Update: Problem stays after update to Mountain Lion. The WindowServer process is in "uninterruptible wait" state ("U" flag in ps output set): imac:~ root# ps ax|awk "NR==1|| /WindowServer/"|grep -v awk PID TT STAT TIME COMMAND 86 ?? Us 50:51.69 /System/Library/Frameworks/ApplicationServices.framework/Frameworks/CoreGraphics.framework/Resources/WindowServer -daemon Any idea for diagnosing what blocks the process? Any idea for "waking up" the process?

• Strange focus bug in Firefox (chrome vs content)

  - by Marius

  Here is a strange bug I'm experiencing in Firefox: I can only use either the chrome, or the content, not both at the same time! For example, I can click on tabs and the toolbar icons, focus the search bar and write in it as well as the address bar, but if I try to click on anything in the content (eg a link or a textfield to write something), then nothing happens. The mouse pointer doesn't change either, it just stays a pointer when I hover over things, and the links I hover don't react either. But if I alt-tab to another program (or click on it in the taskbar), then back to Firefox, then I can use the area that I click on. So if I click somewhere on the webpage to get focus back to Firefox, then I can click on links and write things (like this text), but I cannot click on tabs or refresh or anything else in the chrome. I can't even click on the minimize, restore and close icons! To get focus back on the chrome I have to alt-tab to another program, and then click on the chrome to get back to Firefox to be able to use the chrome again. I've tried closing and starting it again, but the bug is still there. I have experienced this before, but I don't remember what I did to fix it. This bug seems to occur sometimes when I wake up the computer from standby, but I leave by computer in standby all the time, so that is not the only factor.

• Cannot Connect To VMWare Guest OS Using Either RDP or VNC

  - by Humanier

  Hi, I have a PC (Windows XP SP3) with VMWare Workstation 7 installed. The VMWare hosts Windows Server 2003 Enterprise Edition R2. RealVNC (4.1.3) is installed on both OS'es. Both of them use Hamachi2. Host OS (WinXP) also runs ZoneAlarm Firewall. Hamachi network is set as trusted. My goal is to allow RDP and VNC connections to be made to the guest OS (Windows Server 2003). Both options work absolutely fine if I connect from the host OS. However I have problems when other computers from our Hamachi network try to connect the guest OS (Win2K3). 1) RDP connections. RDP window opens, shows black content and after 15-20 seconds displays following error: http://lh6.ggpht.com/_yQhsRRimgKU/TArRrtiteQI/AAAAAAAABZA/e96za-y9wzo/rdp_error.JPG 2) RealVCN connections. Users are able to connect but all they see is a black screen inside VNC window. At the same their input (keystrokes or mouse moves/clicks) are visible when looking at the console window of the Win2K3. I really appreciate any ideas on how to resolve mentioned problems. Thank you in advance.

• Firefox crash on first load on Ubuntu Linux on Windows Laptop

  - by Ira Baxter

  I've had a Dell Latitude laptop since about 2000 without managing to destroy it. A month ago the Windows 2000 system on it did something stupid to its file system and Windows was completely lost. No point in reinstalling Windows 2000, so I installed an Ubuntu Linux on the laptop. Everything seems normal (installed, rebooted, I can log in, run GnuChess, poke about). ... but ... when I attempt to launch Firefox from the top bar menu icon, I get a bunch of disk activity, the whirling cursor icon goes round a bit and then everything stops: disk, icon, mouse. Literally nothing happens for 5 minutes. Ubuntu is dead, as far as I can tell. A reboot, and I can repeat this reliably. So on the face of it, everything works but Firefox. That seems really strange. The only odd thing about this system when Firefox is booting is that while it has an Ethernet port (that worked fine under Windows), it isn't actually plugged into an Ethernet. As this is the first Firefox boot since the Ubuntu install, maybe Firefox mishandles Internet access? Why would that crash Ubuntu? (I need to go try the obvious experiment of plugging it in).

• Windows XP over two monitors, but one of them switches off at boot... how to fix? How to switch bac

  - by jae

  When booting into XP (x64, Athlon II X2 245, 4GB RAM), my main monitor (got two 19" TFTs hooked up, two gfx cards, a 4650 (1GB, the primary monitor's on this) and a 4350 (512MB)) switches off. Logging in blind (cursor down key, typing password) gets me one screen, the secondary. Booted correctly until about two days ago. No clue what's the cause, last change was (if I don't overlook something) installing the ATI 9-12 hotfix. And booting into Windows 7, after returning from 7, it was like this. For some weird reason, I cannot start Catalyst Control Center (I right-click desktop, choose the CCC entry, the pointer changes to hourglass for a half-second... and nothing. Likewise with "Properties"... I think, as all windows open on the primary (off) screen, and no entry appears in the task bar for Properties) Completely stumped. Windows 7, same setup, works w/o a hitch. The primary monitor appears to run in some unknown, but pretty low, resolution, as the mouse pointer only moves onto it at about half-height. But, w/o CCC or display properties, I cannot check. And, obviously, not change anything. Hope this was not too long-winded. And I'm sure I still forgot essential stuff. :P

• Annoying trackpad freeze on MacBook [solved]

  - by Hafthor

  NOTE: Question marked answered because it was forced after being put up for bounty. Actual solution was to have Apple repair it. Trackpad usually works, but sometimes stops responding for around 5 seconds and then suddenly starts working again. Seems to happen when I switch between typing and moving + button-clicking and also when I do a lot of double-clicking. Tried turning off the "Ignore accidental trackpad input". Apple replaced the keyboard/mouse under warranty. Problem remains. Any ideas? Edit: White non-unibody Late-2008 13" MacBook - fully up-to-date OS. Doesn't seem to matter if it is plugged in or not. Edit: Updated to Snow Leopard - seems to have made it worse. Edit: Applying even a little pressure to the left palm rest creates this condition. Apple replaced the top case again and this time it seems to have fixed it. Although, it looks like they may have added a spacer on the left palm rest to "fix" it.

• How can I recover a Fedora 12 installation that is showing signs of disk errors?

  - by Bob Cross

  I am currently overseas (i.e., very far from my normal library of tools) and my primary machine that would normally act as the data server in the performance test that we're trying to run is failing to boot to Fedora 12 properly. This is a machine that, as of yesterday, was booting fine. However, this morning, very strange portions of the boot process were complaining with messages such as "unexpected 0x0 in rpcbind" and "bad file descriptor" (I don't have the error in front of me - scavenged a windows installation to get onto serverfault). Eventually, the boot hung for a long time at the NFS service and then brought up what looked like the KDE login screen but neither the mouse nor keyboard functioned. In olden days, I would try to get to a point where I could manage to run fsck and pray that the bad sectors would come back into alignment just long enough for me to scrape the critical data off of the machine. However, now that we live in the future, it seems like our options in situations like this should be a little more varied. Is there a way to recover a Fedora 12 installation with bad disk sectors that won't boot properly? For completeness, I am comfortable working with bootable recovery distros-on-CD and such but I don't know which one is likely to work best with modern Fedora. In the absence of guidance, I'm frantically torrenting the Fedora 12 Live CD and DVD, hoping to try rescue mode before tomorrow morning.

• System freezes during boot process

  - by slugster

  Hi everyone, i have a machine running Win7 Ultimate. It was running fine, then it just froze - all the stuff i was doing was still on the screen, but mouse and keyboard input was ignored, any animation that was happening on the screen stopped, the machine literally just froze. So i rebooted (power off button), from then on the machine will reboot, but it ultimately freezes again. The instance when this happens will vary - i have made it as far as the Windows login screen, but mostly it will do the POST, then give me the option to press F1 to continue or Del to enter BIOS settings (but of course pressing a key has no effect - it's frozen!). I have disconnected everything not necessary for the boot process, the only peripheral that remains attached is the keyboard. (even the network cable is disconnected). Prior to this the machine was operating fine. The install of Win7 is only 2 days old, and it was a fresh reinstall (i.e. not an upgrade or repair). Can anyone give me an indication of what may be wrong here? I'm not sure if this question should be here or on SuperUser, please migrate it if i have chosen the wrong board.

• Can Vista Windows Explorer be repaired/fixed?

  - by gurun8

  I'm running Windows Vista Home Premium on a Sony Vaio laptop. I think somehow my Windows Explorer has become corrupted. I don't recall any certain inciting incident like installing an unreputable 3rd party app or hardware failure but just recently my system won't wake after it's been left idle longer that 20 minutes and goes to sleep. I've also had problems launch certain apps, like Adobe InDesign CS3, that just basically freeze the system but leave mouse movements functioning for a short time before freezing the entire system which requires a hard reboot to resolve the freeze. The system seems to run normally when used but I fear there's a looming possibility that this is a house of cards and will all come crashing down soon. My question is this, can Windows Explorer be repaired/fixed? Before reformatting the system and starting over, which is most likely what I'm going to be forced to do, I'd like explore (no pun intended) my options in fixing the problem with a patch or reinstall or something of that nature. Reformatting my system will eat up a day or two of my time and I just don't have the time to spare right now.

• Black Screen on Logon (windows 7 home premium)

  - by Blacknight334

  i have been having some trouble with a dell Xps 15 laptop that i recently purchased. it is under a month old, and a problem has occurred, upon logging on just after start up, the computer will just sit on a black log on screen (with the mouse still visible and active) for a few minutes. it is extremely annoying, especially when im in a rush. the laptop is under a month old. So far, i have tried to update the drivers, all windows update, and still, nothing. also, it doesnt seem to do it when i log into safe mode, or if it does, it will do it for less than 10 seconds, then load the desktop (in normal boot, it usually takes a few minutes). i have also run a number of the inbuilt diagnostics, but found no errors. i want to avoid having to do a system restore for as long as i can. does anyone know anything that can help? (the laptop is running a 500gb SSD, 2gb Nvidia 640m, 8gb ram, 3rd gen i7 quad core with 8 threads) thanks.
