• Dark screen when wake / Unable to control screen brightness

  - by John

  Running Ubuntu 11.04 on Lenovo ThinkPad with an Nvida graphics card. The unit goes to sleep when the lid is shut. (The unit goes to suspend mode (not to disk/hibernate), AC gets turned off, running on battery) Upon lid-open sometimes the screen is almost too dark to read. I'm really not sure of the exact cause, (very low batt??). The only fix is a reboot. The screen brightness buttons have never worked in Ubuntu. I have messed w/ the power management preferences. No change. At one point I messed w/ the gnome settings. No change. I have tried a few cmds: echo 9>/sys/class/backlight/acpi_video0/brightness setpci -s 00:02.0 F4.B=10 xgamma -gamma .75 None of these help. Most have zero effect. I think it is and acpi thing, but that is just a guess. I'm out of idea's, and looking for suggestions. Thanks

• Screen doesn't turn back on after resume on a Lenovo Thinkpad T420

  - by Wojtek

  Every time I suspend my notebook (Lenovo Thinkpad T420 - Intel HD graphic card) on Oneiric Ocelot 11.10 and turn it back on, the screen is black. The backlight is on and the system itself loads fine, but the display somehow doesn't get back. The first time after a fresh reboot the screen isn't black, it is mostly white/light-gray and it looks a bit like a distorted image. The pixels fade in until it gets almost completely light-gray. I've got a workaround for this: I switch to the first terminal (CTRL+ALT+F1) and back to X (CTRL+ALT+F7). In most cases that helps. Sometimes, when there's still a problem, I log in on the first terminal and run "unity --reset". Then go back to X - this helps always. I can tell that the system comes back, because I can log in with my fingerprint reader (or wait a bit and put in the password) "blindly", then do the workaround - I am logged in after the screen comes back. So it's only the display that is not working. Any help or advice where to look would be appreciated.

• GNU screen multiuser mode is broken in OS X 10.6 (Snow Leopard)

  - by schustafa

  I'm using GNU screen for remote pair programming. Let's call the local account for the remote user 'pairpair'. I have the following lines in my .screenrc: multiuser on acladd pairpair I have run sudo chmod u+s /usr/bin/screen. However, when the remote user tries to connect to my screen with the command screen -r [my_account_name]/[pid_of_screen] I receive the following message: Attach attempt with bad pid(xxx) The pid listed in the error message matches the pid of the screen process run by the remote user. The remote user's screen process hangs; my screen session continues happily along after the error message disappears. I've tried using both the built-in screen (at /usr/bin/screen) and the screen available from MacPorts, but I get the same error in both cases. This worked on OS X 10.5 (Leopard). I've googled around for the error message, but most of the hits relate to some BSD bug from 2003 or so (which was fixed). Has anyone else seen this behavior? Does anyone have any idea how to make multiuser support in screen work in SL?

• Desktop bigger than screen

  - by alex

  I am using MSI U115 11" netbook (OS: Windows XP Home, graphics card: Intel Graphics Media Accelerator 500) and today after I switched it on, desktop was bigger than screen. To be exact: screen resolution was set to the lowest possible and I could move mouse outside of screen (but only below - left, right and up worked normally, mouse could not exceed screen boundaries). I changed resolution back to normal, but the problem with desktop being bigger than screen remained (as before, only lower part - cannot see task bar, etc. When I hit windows button on keyboard, only upper part of menu start is visible). What I already tried was changing all kind of graphics and screen settings - none of them helped. I also tried to restore the system to few days before, but it didn't help neither. What can I do to make the desktop look "normally"? EDIT: Some additional info regarding screen: Sorry it's in polish - but let me explain. There are two screens I can choose (Monitor domyslny means default screen), but the second one (the default one) is not available. After I choose it and click apply number 1. is used (and as you can see it has only two resolutions available. There are more in the second one - but without 1024x600 though). The two ticked and grayed out options here are Use this screen as the main one and Enlarge Windows desktop to match this monitor's size. Too bad I cannot change them. When I choose the second screen, the first box is unchecked and grayed out. The second box is available to be changed but it doesn't matter anyway as after applying changes it reverts to the first screen anyway. EDIT: Intel Graphics Media Control Panel screenshot.

• Screen Flickering: Hardware or Software?

  - by Wesley

  I have a Samsung N120 netbook (upgraded to 2GB DDR2 RAM) and there has been a screen flickering issue for some time now. However, I have not been able to accurately determine whether it is a software or hardware issue. Here are some of the symptoms: The flicker is white-colored and shows up as vertical lines. Flickering or not, there may be occasionally some random blue patterns (no image distortion) The screen tends to flicker more when the screen is not tilted back all the way. When tilting the screen back and forth, the screen will usually flicker. Some images on the screen may randomly distort without full-on flickering. The screen will flicker only on certain websites, but not on others. A certain part of a webpage may constantly be distorted randomly, even when scrolling. While flickering, the mouse will not move though I'm moving my finger along the touchpad. A connected external monitor does not have any problems. The flickering is completely random and does not seem to follow any CPU/GPU usage trends. Flickering usually gets worse when the screen brightness is turned higher. There will be flickering on battery and while plugged in. Search up "Samsung N120 - Screen Flickering" on YouTube for an idea of what the flickering looks like. However, there is no visible distortions and the flickering seems to stop when the screen has dimmed. Since the problems started, I tried formatting and using Windows 7, then formatted again and went back to Windows XP. The screen was also replaced sometime during this past summer. The uninstallation of the Samsung Battery Manager (on the original install of XP) seemed to reduce the flicker partially, but eventually got worse. So, what could possibly be the problem?

• How to Always Load Internet Explorer 9 in Full Screen Mode

  - by Lori Kaufman

  Internet Explorer 9 has a minimal interface by default, with the tab bar and the toolbar and address bar on the same line. However, you can gain even more viewable space by pressing F11 to go to full screen mode. If you like full screen mode and want to use it most of the time, you can have Internet Explorer open in that mode automatically, by editing a setting in the registry. To begin, enter “regedit” (without the quotes) in the Search box on the Start menu. When the results display, click regedit.exe or press Enter when it’s highlighted. NOTE: Before making changes to the registry, be sure you back it up. We also recommend creating a restore point you can use to restore your system if something goes wrong.

• Display date/time in Ubuntu lock screen (cinnamon-like)

  - by 3l4ng

  I was using Ubuntu 13.04 till a few days ago. I had installed Nemo and I guess cinnamon got installed too (I was still using Unity nonetheless). One of the good things about that was the lock screen somehow changed to mimick cinnamon's (with the background as a darkened version of desktop background and date/time displayed), something like this: I have no idea how this happened, but it looked great. It does not seem to work on Ubuntu 13.10. Anyone has any ideas to get a similar lock screen? I just need to display the date/time on one side with the bg as a darkened version of my desktop wallpaper

• Can't boot into ubuntu, black screen after grub menu

  - by wim

  Ubuntu is not booting properly for me anymore. The grub menu comes up, and whether I choose a linux recovery mode or the normal one I get a black screen after a few seconds. There is a brief message about vga=791 being deprecated, but I am not able to read it fully because the black screen covers it up almost immediately. I have googled for hours for solutions, and most people seem able to solve similar problems by editing in grub and adding nomodeset into the line starting with linux /boot... but this solution is not working for me, I still don't get any GUI. Sometimes I am able to get the dmesg rolling past, I think it was when I removed quiet splash from that line, but still no GUI - the computer seems to be on and working because it responds to a ctrl-alt-del and reboots. I have tried with 3 different graphics cards (2 nVidia and 1 ATI) and swapping them doesn't seem to change the behaviour at all. What else can I try?

• Black Screen on boot on a Lenovo IdeaPad Z575

  - by Davis

  So I tried to install Wubi. On boot, when I select Ubuntu it starts then I get a purple screen then black screen. My monitor is like completely off. So then I have to hold down my power button and shut it off. I boot it up then held shift and typed in "nomodeset" after the second to last line, but then when it boot it went into the command prompt thing and just stopped after "checking battery" or something. This is my first time installing any linux distro. I want to install it alongside windows and dual boot it with wubi because that is easy and simple. This is the laptop I have: http://www.newegg.com/Product/Product.aspx?Item=N82E16834246328

• Black screen with blinking cursor! [closed]

  - by Draco

  Possible Duplicate: My computer boots to a black screen, what options do I have to fix it? From my Windows XP SP3 machine, I downloaded the live image file for Ubuntu 12.04 LTS. I then burned a bootable CD. Then I went into the BIOS and set installation settings to (first) CD drive and (second) disabled. However, when I boot I only get a black screen with a blinking cursor. After some time I might get some error messages. Even if I leave it for hours I get nothing. FYI: I don't know how to go to the GRUB menu. Please make the answers easy since I am a young beginner.

• GameState management hierarchical FSM vs stack based FSM

  - by user8363

  I'm reading a bit on Finite State Machines to handle game states (or screens). I would like to build a rather decent FSM that can handle multiple screens. e.g. while the game is running I want to be able to pop-up an ingame menu and when that happens the main screen must stop updating (the game is paused) but must still be visible in the background. However when I open an inventory pop-up the main screen must be visible and continue updating etc. I'm a bit confused about the difference in implementation and functionality between hierarchical FSM's and FSM's that handle a stack of states instead. Are they basically the same? Or are there important differences?

• Ubuntu live session crashes and boots to a black screen

  - by Bsc

  I heard about Ubuntu from a friend and wanted to test it out. I made a Pendrive Ubuntu 12.04 with a persistent file using Universal USB Installer. The first time I booted Ubuntu from the USB everything went like usual. I was just a bit exploring Ubuntu and had installed a few apps nothing more. Today after using Windows 7 for while again, I wanted to boot Ubuntu again. When I boot it, the usual loading screen comes up but after that it crashes and gave me a black screen. Is there a possibility to check the USB on errors or do I need to reinstall Ubuntu on the USB?

• Ubuntu doesn't give the intended screen resolution

  - by JMCF125

  I have recently created a Ubuntu 12.04.2 64 bit virtual machine on VirtualBox, and I am not very used to Linux (I used Linux Mint for a few weeks some time ago), so please refer the full name of stuff, not just "the what-not-command". The problem is I can't set the full resolution my computer supports (I think it is 1366 by 768), I have found similar questions and tried most of the respective solutions, thy did not work. If I type xrandr to the terminal I get: xrandr: Failed to get size of gamma for output default Screen 0: minimum 640 x 480, current 1024 x 768, maximum 1024 x 768 default connected 1024x768+0+0 0mm x 0mm 1024x768 61.0* 800x600 61.0 640x480 60.0 As you can see, the maximum is too low. And in the settings of the screen (I mean, with GUI) only 1024x768 and 800x600 appear. I don't remember exactly which answer of those questions, but it was one in the terminal (again, with xrandr) that made the resolution I wanted appear (although it gave an error when selected, not even changing to the 1366x768 resolution first and then back to 1024x768).

• Screen has 1px vertical dead area on the right side

  - by pileofrocks

  Meaning that I can not click anything on that 1px vertical area (such as scrollbars). Illustration (purple = screen, black = the dead area): I am thinking Compiz has to be the main suspect, especially as on a guest account, this problem does not exist. I have a dual-monitor setup and this does not happen on the 2nd screen. However, turning off the 2nd display does not make any difference. I had this issue already before upgrading to 13.10 and while doing that, I also resetted all Compiz settings and re-loaded my profile configuration file. I have tried disabling all Compiz plugins under "Window Management" What next?

• Cannot login via Unity login screen after upgrade to 12.04

  - by codesurgeon

  Logging in via the shell accessed through Ctrl+Alt-F1 and logging in as guest via the graphical user interface work 0O When I try to log into my standard user account via the graphical interface, the screen flashes to black for a couple of seconds and bumps me back to a pristine login screen. Entering a wrong password for my user account yields the standard error message - my user account and credential verification seem to be OK. I suppose that my individual graphics configuration causes problems ... I'm not sure how to reset that. I've tried stopping the UI via sudo service lightdm stop executed sudo nvidia-xconfig and restarted the UI sudo service lightdm start to no avail. My workstation has a Nvidia GeForce 560-448 graphics card. I've tried getting this fixed with the latest Nvidia 64-bit drivers (cURL'ed from the official website), that is 295.49 and the latest beta driver 302.07. Anybody have an idea how to get this fixed? Your help is appreciated :)

• SFML 2.0 Too Many Variables in Class Preventing Draw To Screen

  - by Josh

  This is a very strange phenomenon to me. I have a class definition for a game, but when I add another variable to the class, the draw method does not print everything to the screen. It will be easier understood showing the code and output. Code for good draw output: class board { protected: RectangleShape rect; int top, left; int i, j; int rowSelect, columnSelect; CircleShape circleArr[4][10]; CircleShape codeArr[4]; CircleShape keyArr[4][10]; //int pegPresent[4]; public: board(void); void draw(RenderWindow& Window); int mouseOver(RenderWindow& Window); void placePeg(RenderWindow& Window, int pegSelect); }; Screen: Code for missing draw: class board { protected: RectangleShape rect; int top, left; int i, j; int rowSelect, columnSelect; CircleShape circleArr[4][10]; CircleShape codeArr[4]; CircleShape keyArr[4][10]; int pegPresent[4]; public: board(void); void draw(RenderWindow& Window); int mouseOver(RenderWindow& Window); void placePeg(RenderWindow& Window, int pegSelect); }; Screen: As you can see, all I do is un-comment the protected array and most of the pegs are gone from the right hand side. I have checked and made sure that I didn't accidentally created a variable with that name already. I haven't used it anywhere. Why does it not draw the remaining pegs as it should? My only thought is that maybe I am declaring too many variables for the class, but that doesn't really make sense to me. Any thoughts and help is greatly appreciated.

• Login screen theme and background lost

  - by Sebastian Potasiak

  I tried to change my LightDM background and theme in Ubuntu 12.04 LTS beta 2, changing /usr/share/glib-2.0/schemas/com.canonical.unity-greeter.gschema.xml file (I don't even know if it would work, but I couldn't find any other way), and I failed and restored original file. Also, durning the same session I installed gnome-shell-extensions package, but it didn't work either. (I didn't remove it) Now my login screen looks a bit coarse, without theme and background. (It looks like MS Windows 95 a bit - square buttons and text fields) My question is, how to repair login screen (or how to customize it propely) and how to make gnome-shell-extensions work.

• HP DL360 G4 screen resolution problem

  - by dogmatic69

  I just bought an old blade server to mess about with at home and cant get the thing to work. I have run the installer 11.10 x64 server and that was fine. After installing and rebooting, POST is fine but when grub kicks in the screen shows a popup type box complaining that it cant use the resolution. I have tried different screens and its always the same. I can reboot and go back into the installer and the screen is fine. I tried to follow some guides on-line about changing the resolution but I cant get a terminal. I found one in the installer but that is using the ram as /. the installer says 'the drive is mounted as "/target"' but I don't see that, nor /mnt/target. Could anyone help me configure this and get it running. Thanks.

• Kubuntu 12.04: Change login screen background?

  - by drezabek

  I am having trouble changing my login screen background. I can select the default wall paper, the Kde-default one, but when ever I select my own custom wallpaper, there is no image, just a solid color. Normally, I would just ignore it, but the thing that bugs me is that this is a fresh install of Kubuntu 12.04 64bit, and the OS before this one, the one I overwrote, I had no trouble using the exact same image as the background... Settings In the System Settings application, Login Screen settings, Background tab, enable background, Under "Background", selected Picture, under options, selected Position: Scaled. Colors: Single Color. Blending: No Blending.

• Can't change screen resolution Ubuntu 10.04 (BT)

  - by Universal Coder

  I'm using Backtrack 5 R2 , what is based on Ubuntu 10.04 LTS. It is installed on Samsung Laptop , and default screen resolution in Windows for it is 1366x768 , but BT/Ubuntu Screen Resolution GUI tool (System=Preferences=Monitors) shows that only resolution available is 1024x768 , and called my monitor as "Unknown". Found a solution , that I have to change resolution in /usr/share/xresprobe/xorg.conf , but I did it , logged out/in and restarted many times , but it took me nowhere. Tried with xrandr , but it shows only mentioned 1024x768 as only solution , and when I tried to input needed resolution , but it did not accept it , because it is not available. As much as I googled , there are a lot of people that had similar problems with BT , but most of them solved with VirtualBox additional tools , but it can't help me , because I've installed it as second OS. In one forum read , that same problems is in Ubuntu 12 , so I ask this question here.
