If I try to logout or switch user, I end up with a black screen and a blinking cursor. I can type and the letters show up on the screen but don't do anything. I can do Ctrl-Alt-F1 and then "sudo service kdm restart", but I'd rather fix the underlying problem..Google gives several pages with similar problems but they all seem pretty old (2007), and they don't seem to apply to 10.10.
View 8 RepliesEvery time me or another user uses the "log out" option were faced with a black screen that does not go away, unless the computer is restarted. i've left it for an hour thinking it might have just slowed down or something but that was a no go, and it happens each time you try to use it. the strange thing is if the black screen is up programs still run. i have a media server running most of the time and i have no problem accessing it while the black screen is showing.
Another problem im having is that sometimes when a user logs in they have no sound. the sound icon is showing that no sound is installed, but when another user logs in there is no problem and sound works fine.
Lastly i dont know if this is a feature or a problem. the first user to log in will always have control over the network connection. for example if my mother logs in first the icon to switch connections will show up on the top of her screen and she has full access to what connections she wants to use, also her account is just a basic user account. now when i log in i wont have the network icon on the top of my screen, and my account is the main admin account.
After updating my Slackware-Current (there was kernel and glibc package updates), I just get a black screen with a blinking "_" in the top-left corner when I logout.
I checked /var/log/kdm.log and found these errors:
Code:
I've found a workaround: uncommenting "TerminateServer=true" in kdmrc.
I'm trying to run Slackware 13.37 64-bit in a VirtualBox virtual machine. My VirtualBox version is 3.2.12. I had to disable compositing to keep the X-Server from reporting a segfault.Now the problem is that on logout from KDE I get a completely black screen. I can switch to a console session and type commands to get the login screen again.
telinit 3
telinit 4
I tried editing "kdmrc" to add the line "TerminateServer=true" but it had no effect on the problem.I had this working with Slackware 13.1 at one time, but I can't seem to get it working properly now even without desktop effects.I'm trying to avoid changing my VirtualBox software since each version seems to just introduce new and different bugs. The 4.X versions are not yet very stable.
I have Lucid setup for multi user. Whenever 2 users are logged in and one logs off, it freezes on a black screen. It looks like it logs off OK and is on its way to the main login screen but never gets there. I found some older posts describing this problem but no solution. I tried to post to that thread but got a message saying I was not permitted. I am new to Linux and am struggling to figure out how to problem solve issues in Ubuntu.

Big mistake The screen went black.I can force a shutdown, login and I get the same black screen. I tried hooking up an external monitor and the monitor showed no input so I'm guessing my laptop doesn't have that capability with Fedora.This is my main computer.

Whenever users click logout they're logged out, however after that all i get is the background screen with the cursor. The cursor is able to move, but no login screen.If i go to a terminal window alt+f1 and do a service gdm restart, then the login screen goes back to normal.
View 3 Replies View RelatedHowever, there are one or two stability issues. In particular, over the last couple of days, I have seen two occasions where my screen suddenly goes blank, and after about 3 seconds I am presented with the login manager. I can then log in, and the desktop works fine again. Of course, everything I was doing is gone... So, where do I look to find what is causing the problem? I'd like to find out and either fix this here or submit a useful bug.

As a normal user I have activated the functions of the Quit applet, i.e. Logout, Shutdown and Restart are active buttons. I am able to restart or shutdown, no problems. But when I use the Logout button I don't get logged out, just returned to the login shell & I am still logged in as my user. I don't have a display manager installed and I do NOT want to use a display manager such as XDM or GDM. How do I get the Logout button to actually logout the user? It appears I am only getting logged out of the x-session, but I want complete logout.

Only ever use the KDE desktop so completely removed XFE and the rudimentary Gnome left behind on the install.
Not a desperate problem just an annoyance.
Everything works fine, except if I logout the next login screen is using a really tiny font and I can't seem to find anywhere to change it.
The DPI must be about 10, as I can't even read it when blown up on my projector.
Recently I've been having an issue where every now and then, all of a sudden fedora logs me out and takes me to the login screen.
All my unsaved work is lost and I have to log back in again.
Is there any way to diagnose this problem and figure out how to solve it?
I'm using Slackware 13.1.
Whenever I logout of KDE and go back into console mode, the characters at the console screen become unreadable gibberish. Is anyone else having this problem?
I can ctl+alt+F? to work at another console screen, but the ctl+alt+F1 screen remains unreadable until I reboot.
I have a problem with garbled graphics after resuming from hibernate or logging out (when the screen blinks and goes back to the display manager). It only occurs when I do either, about half the time. What happens is the edges of everything "bleed" horizontally (left to right) in red and green colors and black text on a white background becomes entirely unreadable (but white text on a black background is readable and just looks a little bolder). If I shut down or restart the computer (softly) when the screen has garbled, then it will freeze and not even the SysRq keys work (I have enabled it in /etc/sysctl.conf). Then the only thing left is to do a hard restart (in which case there's a voice saying "System failed VGA test" before BIOS/GRUB loads) or poweroff. Powering it off and then starting it again works fine. I did a google image search and this is sort of how it looks when it freezes: link
Once the screen has garbled (but only if it hasn't frozen) I can use SysRq to issue S E S I S U O to shut it off and then power it on, and that works: then I get a non-garbled command line after sigterm and it shuts off and starts up properly. If I issue B instead of O (to restart) I get the "System failed VGA test" on boot (but it doesn't freeze when shutting down). Hibernation is easy enough to fix by just turning it off (it's not a laptop so I don't need it anyway), but it still happens sometimes when I log out. So as long as I never change users the system works perfectly and this never happens. I've tried GNOME, Xfce4, OpenBox without any DE, gdm3 and SLiM and the problem persists in all of them.
Some system details:
Debian Squeeze i386 (using only software from the stable main repository)
Kernel: 2.6.32-5-686
Video card: ATI Radeon 9600SE (using the preinstalled open source drivers)
Motherboard: ASUS P4P 800-E
By the way: sometimes when it's in the process of shutting off (when the display hasn't been corrupted), after it kills all graphical applications, I can see that the CLI text gets the garbled look, but at that point the poweroff works without freezing. This is the most similar sounding bug that I could find: [URL]. Unfortunately I can't find a solution to it, and most people who have similar problems seem to get either the garbled graphics or the freezes, but not both. Also: how safe is it to keep shutting off with SysRq to recover from this? Can I get disk errors?
When trying to "Leave" the system (either via the small button on the lower right of the taskbar or by right clicking on the Desktop and selecting "Leave") the logout / shutdown / restart screen comes up. I have the "Logout" desktop effect activated, which is supposed to desaturated the background when the Leave screen appears. However, instead of simply greying out the background, the image on the desktop and the rest of the screen also gets slightly distorted, with seemingly random distortion effects cropping up all over the place (e.g. horizontal lines or large blurs).
These distortions are different every time the Leave screen comes up. The Leave screen itself is displayed fine, and apart from the dodgy background I have no other issues with the whole process (the system shuts down or restarts properly according to my choice). I am using the Radeon drivers, and all other desktop effects I have on (Magic lamb, cover switch, present windows, etc) work fine and without a hitch. It's only the Logout effect that seems to glitch. Are the distortions intentionally created by the effect in order to emphasize the focus on the Leave screen?
Alright guys. I need to find a way to enable a black screen screensaver (or turn off the monitor, or something to avoid burn in) while the machine is sitting at the login screen and completely turn off the ability for the computer to sleep. how I can accomplish that?
View 1 Replies View RelatedI have recently installed 11.04 natty on Intel Core i3-2100 3.1 GHZ using its own graphic accelerator. When the screen is idle for a long time, more than 1 hour, I get a black screen with the mouse arrow but nothing else. the mouse moves the cursor and Ctl+Alt+F1 does work. How to fix this problem?
View 4 Replies View RelatedI installed Ubuntu 11.04 today as the main OS on my laptop.I had deleted my XP partition, and repartitioned it according to a guide I had found. (http:url)......Basically it was setup like this: 500mb ext2 primary partition, has the grub folder, I believe this is either the '/' partition, or the '/boot' partition 2gb swap space logical partition
10gb ext4 logical partition -- this is either the '/' or the '/boot', it contains the 'bin,boot,cdrom,dev' etc folders 243gb (the rest of my hard drive, with the exception of a partition that contains documents and files from my XP OS, formatted to NTFS) ext4, this is the one that has all my desktop/documents/etc folders.After Ubuntu was done installing, I had some message pop up about installing an ATI proprietary driver for my ATI graphics card (an ATI Radeon HD 4330, I believe, I may have messed that number up). I installed it and rebooted, no problem.
Next, I had another update window pop up with 198 items checked and ready to download and install. I went through all of this, and rebooted, again, no problem.Next thing I did was install some apps that were essential for me to have to use for my work (an ide, chat programs, etc). No problem with any of that.Last thing to install was the OSE Virtualbox, and then I installed WindowsXP Pro and Windows Vista Business, then installed the guest addition addon for VB. This all worked without any issues whatsoever.
Time goes on, and I notice my computer is heating up much more than (seemingly) normal. I begin to wonder if its my graphics card. So I shut down the computer and let it cool down. Reboot, and no problem, still working fine.Then I opened a couple of apps and tried a simple game (can't remember the name) I believe it was a simple 3d topdown, as I wanted to test my graphics card. This is where things seemed to start to go wrong. My laptop began hanging, not even allowing me to access the terminal via ctrl+alt+f2. The screen flashed and I saw the blue/green/grey fuzz that I get when the graphics card is starting to heat up too much. Then everything hangs and I can't do anything at all, including move the mouse. I did a hard reboot (I believe this is what you call pulling the plug/pressing the power button, correct me if I'm wrong). I then rebooted, saw a chkdisk, then it booted seemingly normal, but it hung right after the purple screen after the grub screen.
This is pretty much where I'm at right now. I strongly suspect the fault is with the ATI drivers, but have been completely unsuccessful in my attempts to fix it. I've googled just about everything I could think of, along with searching these forums. I've tried just about everything listed in the forums, but to no avail.I've tried the commands that are supposed to purge the ati drivers, but all I get are errors that say they can't remove the 'virtual drivers'.
Right now I'm booting off a live cd, so I know the computer still works fine, just not my actual installed OS. I'd really like to get the issue resolved without having to reinstall, as it took quite awhile just to get it usable in the first place, but this has already taken so much time, I may just resort to that if we can't solve it any other way. Got too much work to catch up on as it is.As a re-instated note, perhaps if you have any tips, but not particularly about fixing the OS, my laptop (I'm strongly guessing my graphics card) is heating up much more than normal, compared to that when XP was installed. Is this more than likely just a driver issue, as is the rest of it? Also, I did have Compiz installed, though I didn't choose for it to be installed, I believe it came pre-installed. I've heard it could cause some issues, though I have no idea as to the validity or relation to this particular issue.
Edit:
I just remembered while searching for a solution, I found a post somewhere that said something about the information not being sent to the monitor from the graphics card properly, thus no desktop. I'm guessing that'd still fall under the driver issues, but again, I'm unsure. I would think that wouldn't be entirely true anyway, since I can still see my mouse fine, just no desktop, only a black screen.
I have Ubuntu 10.04 running kernel .26 installed on my Dell Dimension 2350 with 512mb of memory. The problem I have been having is, When I am using the computer mostly Internet stuff for no reason the monitor will go black then on the screen it will be at a terminal screen, kind of like when you start up the computer, I don't remember what is all on it but the last thing in the list was: checking battery state: OK after that the screen will flash in multiple colors and then it goes into a loop of just black screen than a colorful flash and back over to a black screen. the only way I can fix that is by holding down the power button. this will happen mostly on face-book on the games and just on the profile page, but it does happen just checking my gmail or play solitaire it does this around 4-8 times a day.

This obnoxious bar has just appeared in Smplayer at the top of the screen. It stays there even when I go full screen. Now full screen isn't full screen and there are black edges on both sides of the screen. I have not be able to figure out how to hide it. I do not need or want this onscreen display. How can I configure Smplayer to make this go away? How can I get my 16:9 full screen aspect ratio back? I have done nothing to mplayer or smplayer as far as editing any or changing any configuration files. I tried several videos and it displays on all of them. It was not there last time I used Smplayer.
