Ubuntu :: 11.04 Hanging After Going Blank In After The Lock Screen?
Jul 7, 2011
Ubuntu hangs after the lock screen menu disappears. When it goes into the lock screen and the menu disappears Ubuntu stops responding. Moving My mouse or typing on my keyboard doesn't help. The password screen does not appear. It does not appear to be this bug: as it stops responding within a second of the screen disappearing. I have confirmed that nothing is wrong with my monitor or video card using my brothers setup.
I installed CentOS 5.5 last night using the DVD ISO (from a USB drive thanks to the Universal USB Installer). I selected the Server and Virtualization packages, and finished the install all the way through. At the end, the installer asked me to remove any installation media and reboot the system. After rebooting, the system hangs on a blank screen with a blinking cursor in the top left corner that does not accept text. This is before the GRUB screen appears. For partitioning, I created a 4GB swap partition on sdb and a 16GB ext3 partition on sda, mounted at /, with the remaining free space on sdb mounted at /storage.
Does anyone know why this system is hanging before the GRUB menu?
I have 2 servers, I set the first one up so that I can remote to it and connect with VNC over ssh by following:[URL]ServerThe 2nd server I did the same, but I cannot connect! When I do, vncviewer prompts for a password and then opens a window of the correct size, but it is all white and then my ssh session is locked! I can't enter any more commands, I have to kill the session.
I installed the new 9.12 cat drivers in the usual way (init 3; rpm -e the old drivers; generate new rpm; rpm -i new drivers; init 5), but instead of starting like I expected, I got a blank screen and what appeared to be a hard lock (keyboard lights don't toggle, Ctrl + Alt + Backspace and Ctrl + Alt + F1 don't do anything).
I switched back to radeonhd, but I'd like to get the proprietary drivers working if possible.
I am having the same problem, as soon as X tries to load my screen just goes blank. I have an ATI Radeon 9550. At first I tried switching between VGA and DVI as well but upon ruling that out, I switch to my on-board video card and that is working thus far, but I'm trying very hard to figure out a way to be able to switch back. Anyways I'll check back in later on if I have any new information I will post.
I have experienced that the button in my main menu "Lock Screen" does nothing, so I can not lock my screen. What could be the problem? Is there any command in terminal what I could write, so I can see is there an error output or something?
When i use my computer (whether it's going online, typing, playing a flash game, or coding) I get these "Black Flashes" that are becoming longer and more frequent. A "Black Flash" is when my computer screen turns blank (but you can still see the backlight) and i have to press the NUMpad ENTER button, shake my mouse furiously, or click my mouse, which sometimes causes undesired actions, but gets me my screen back. sometimes the Black Flashes last a milisecond or 5 seconds or i have to hold the power button and restart because it won't come back on.
When I hit Alt+Ctrl+L my system is starting the ScreenSaver but not locking the screen. The keybinding is correctly set. This is happening in only root account but in another user account it works perfect !
I just recently installed updates from Ubuntu and the system is hosed. I get the Ubuntu screen that flashes real quick then it goes to the Nvidia like cursor. I am pretty sure something is hanging up on startup. I cannot get to a console, cannot do anything but reboot with ctrl alt del. Then I get the briefest flash of the screen but not long enough to see where it was hanging up at. I ran the same updates on this machine, if I could get the old school informitive startup screen instead of the windows like tell you nothing start up screen I might at least know where to start looking. Right now I have zero clue as to what the updates broke. I cannot even get to log files as there's no console, no ssh, nothing. version is Ubunto 10.4 LTS.
I have some trouble booting the current KDE Live Cd (11.2) on my Laptop. I tried USB and CD both. The laptop hangs on the bios bootscreen and I cant select any further option like a boot device. No problem I have with an Ubuntu CD.
I just installed OpenSUSE 11.4 on a completely blank machine, empty disks, etc. using a Network Install. The install appeared to run OK, but when it rebooted to do the configuration, it hung. I tried a manual reboot a couple of times, then booted in FailSafe mode - came up OK and ran through the auto-config. Now, it still boots up ok in FailSafe, but in normal mode I get the wallpaper on the screen, but it hangs there.
Is there a known problem with the Lubuntu 10.10 image here? I have downloaded it to two different computers, then burned the images to two different blank CD's (different brands) and neither loads. Both only get as far as the Lubuntu menu, once ENTER is pressed at that point to load the LiveCD, a blank screen eventually appears with a flashing cursor at the upper left of the screen, that's it. They were both burned using the slowest burn speeds available.
What happens is that I resorted to deleting my .kde directory after my kid destroyed my profile where title bar, menu, konsole get broken. After deleting, I login again thus regenerating the .kde directory. To avoid my kid from messing my desktop, I tried to lock it. It does not lock.
It just need a KDE full restart perhaps since when I login the other day, it now works.
I'm updated to Slackware current for almost a month already and have not played a lot on KDE desktop (busy programming stuff).
However, on day I tried to lock the desktop in KDE to avoid the kid from destroying my cool desktop setting, but it didn't lock. Cool, so I tried screen saver and add an option to lock the screen.
When I test screen saver, it displays. But when I wait for 1 minute(I set it that way), it doesn't fire up. Not even after 15 minutes which I think the default.
It usually work before (several months ago) using the lower version of KDE. It is just last Saturday that I noticed it.
I tried to dig the profile management but I could not find anything relevant there.
The day started as usual until I got the very bright idea to install Ubuntu. A new OS along side W7, that sounded great. I checked some guides on the Internet, it was all very straight forward. Install it and Grub will show you the OS:es when you boot up. I installed Ubuntu, rebooted. After the BIOS messages the screen goes blank and my screen on-button begins to blink, as if trying to find a signal, I press enter, it reboots instantly. After BIOS messages I get to a screen that says "GRUB error: uknown filesystem grub rescue>"
I've looked through everything here and nothing works. I've tried to fix the mbr-thingy using Windows Repair and even though it says "one partition was updated with new boot-thingy" when I reboot, I get into that very same grub rescue. I think my setup has something to do with it. I run RAID0 (2x360Gb hard drives), first having C: at 50Gb and then the rest as F: for programs and such. What I did was that I shrunk the F: part and then used that as partition for Ubuntu. Also please have a look at these screenshots, my partitiontables and such seems completely wacky to the raid: Where should the boot-loader go? I'm very, very new at this. I've had Ubuntu Netbook remix on my netbook for a time but still treat me as an utter beginner.
I'm trying to test out using xubuntu 10.04 on my one computer and keep getting a black/blank screen after selecting the 'try' menu option.Is there a way to fix this?I have tried some of settings via F6 with no luck.
FYI -The CD works fine as I have tested it on other machines.The version I am trying is xubuntu x86 (although I have tried ubuntu 10.04 x86 with similar results).I can Alt+Ctrl+F1 fine and get to the cmd prompt
I fixed this issue on 10.04, but just recently (1 hour ago) upgraded to 10.10 and am having the same issue. Machine boots fine, but the screen is blank for most of the boot, and plymouth is up for about a half second before I get to the login screen.I've tried searching the threads, but for the life of me I can't find the solution and can't remember what I did to fix it on Lucid.
like any other Linux newb, I came to Ubuntu because my Windows crashed one time too many. And I chose Ubuntu because "it just works". But these past few days that hasn't been true. I'm posting this from a netbook with Ubuntu, and am having no problems whatsoever, but normally I use an Acer Aspire 5920G laptop. I'll include the specs as written on the sticker:
* Intel Core 2 Duo processor T5250 (1.5GHz etc) * Up to 1024 MB Nvidia Geforce 8600M GS Turbocache * 2 GB DDR2
Let me know if you need more details, and I'll add them later. Now, what happened was I clicked "hibernate" while leaving Firefox open. (I've done this hundreds of times, no problem) And when I went to turn it back on the next day there were weird graphical glitches in the loading screen, and it booted to the "tty1" prompt screen. I did a lot of googling and found quite a few posts about it, but the solutions either didn't work, or I didn't understand them. After trying several different suggestions from this forum and others, I managed to delete the graphics drivers. That enabled me to boot in low graphics mode, and naturally, I tried a whole bunch of things to make it work properly again. That only made it worse. Now it went straight from the loading screen to just blanking out and turning the display off. So, I tried new things. Over and over. The weird thing is even when I disconnected my harddrive and ran from a Live USB, the problem persisted. Could there be an issue with the graphics card itself? Anyway, after reconnecting the harddrive I tried to boot again. And it suddenly worked. Even HDMI to my bigger screen worked.
I have been running 10.04 quite successfully, when I upgraded to 10.10, I have a problem with the newer kernels. If I let it boot into the latest one 2.6.35-23, I get the Ubuntu 10.10 splash screen for a second then a blank screen, same with 2.6.35-22. I have to run with 32-25 to get it to load the gui.
I have an AMD Sempron 2800, 1.6GHz pc, but I'm not sure if it's running 64bit.
I've been running Ubuntu 10.10 very smoothly for a while now. Decided to upgrade to 11.04 - managed to corrupt the hard disk the first time by letting the laptop hibernate part of the way through but reinstalled from a live CD of 11.04 and it's now working except for this issue.
If I shut the screen on my laptop (or press the screen off button) either the screen won't come back on or it will but frozen (I can move the mouse but not click on anything etc.) In this state music continues to play (from spotify under wine) and if I press my hibernate shortcut (power button) the computer hibernates, only to wake into the same situation. I've got a Dell Latitude D520, upgraded to a bigger hard disk and more ram - the ubuntu partition has 50gb. Windows is working fine.
Edit: I noticed a sticky thread which includes something about a blank screen but I think this is a different issue?
i have just put a Geforce 7300 GT graphic card into my machine the problem is the max resolution I can get is 1024x768 at 60 hz the screen is a benq fp71g+. also the screen goes blank when i click on the display icon in system settings. i know that the screen can be run at 1280x1024 so I don?t know where the problem is.
I'm trying to use 'gnome-screensaver-command --lock' to lock my computer so that when my girl is on it I can **** her off
I can run the command from the terminal and it works just fine, but when I ssh into my computer and try to do it, I get the error
Code: ** Message: Failed to connect to the D-BUS daemon: /bin/dbus-launch terminated abnormally with the following error: Autolaunch error: X11 initialization failed. It'd be nice to be able to lock my screen from wherever.
I am using Ubuntu 10.04 LTS. I leave the pc for only a few minutes and when I come back the screen is black. I press a a key or pass the cursor over and it opens but I have to enter my password then press the unlock button.I am none to happy with this happening each time I happen to step away from my computer for a couple of minutes. I would like to know if there is a way to disable or turn off this function
Sometimes after I enter my password after the screensaver has locked the screen, it will not take my password (even though entered correctly). It seems to lock up. After about 2 mins it says something about a time-out (wish I could do screencaps). Then it will reset and have a gray window the same size as the password input window but on the upper portion of the screen, and a password entry window as normal, but in the lower part of the screen. This time, it accepts the password and logs me in.This is a 2-part post.First, how to bypass having to wait for the timeout (for whatever is timing out).The second is to see if anyone knows an answer to the problem and a fix.After it freezes, hold CTRL-ALT and tap F1.This will taking you to a virtual terminal. Log in with your username and password. Then type:
Code: $ pkill screensa This will match gnome-screensaver and kill the program that is frozen. You then need to type
I upgraded to latest 10.04 live x64 desktop today. Clean, fresh install.Before I was using 9.04 and had the same issue at first.I don't want the password lock screen when resuming from suspend.I disabled everything, lock in screensaver settings, all lock entries in gconf-editor. I also tried setting LOCK_SCREEN in /etc/default/acpi-support to false.Nothing helps Is this maybe a bug, since it's still beta? I don't know what else to do
I am experiencing a really annoying issue with ubuntu 10.04. Wether the "lock screen when screen saver is enabled"option is ticked or not, it will anyway request me to insert the password.
And that's but the lighter problem: Screen saver keeps poping on while I write, browse and whatever, and changing its properties won't help at all. It just keeps pestering me! (while i'm writing this, i've already had my screensaver popping in about 15 times)
And last but not least, even if I log as administrator and unthick the "request password"... it will always keep asking ... what to do?
my desktop cannot be locked anymore. Furthermore, after waking up from suspend, I am straight in the desktop, it does not ask me for my password anymore. The screensaver also does not activate anymore either. I'm still using Ubuntu 9.10 on a Dell Latitude D820.
Living with others, I've made it a habit to lock my laptop if I walk away from it (Ctrl+Alt+L), but with the recent upgrade to 11.4 I've run into a problem: when I go to unlock my laptop it just gives me a black screen instead of the "enter your password" menu. All I get is the mouse.
The only work around I have for this is to log into a TTY and then restart the laptop.
In case it's significant, the exact process I go through is as follows: Lock my screen (Ctrl+Alt+L), close the laptop lid (power management is set to just blank the screen instead of suspend), walk away for 10+ minutes, open lid, and then I run into my error.
