Login as myself, girlfriend wants to use her login to check something, all good.I switch back to myself, I get a black screen with just my cursor. Most annoying. I have to ctrl-alt-f1 to reboot. I've tried killing various process from the term, but nada. I've also tried uninstalling gnome-screensaver as was mentioned in another thread when I searched, but no joy there so far.

I'm using Ubuntu 11.04 64bit. Mainboard Gigabyte GA-H55M-S2V. My LCD is a HDTV monitor which is plugged to onboard graphic card.
I don't know what happen with my Ubuntu. It sometimes goes black when I try to wake my PC when it's suspended previously. The screen is black, but I still can move mouse cursor. I also can do blindly click on stuff on screen (I could play a song last time by clicking randomly). This problem also happens sometimes when I switch back to PC from TV (My LCD is a HDTV monitor).
The only action I can do when it happened is reset my PC.
I have a problem with Switch User on a newly installed Ubuntu 10.04 on Asus Eee 1101ha.When I try to use Switch User, I just get to the Lock Screen of the currently logged in user, where I'm asked to enter a password.There is also "Switch User" button on the Lock Screen - the screen gets black and then gets back to the same Lock Screen. Login Screen is not displayed.

View 11 Replies View RelatedI've run into a strange problem with GDM that I haven't managed to find a solution for yet, either by trying myself or googling, and I have run out of good ideas. I'll just infodump here about the problem and what I've tried etc;
I installed Ubuntu on a new PC a few weeks ago, setting it up with autologin for my mom and a separate user for myself, using the on/off-icon menu in the top-right corner to switch to my own user and back as needed, and logging the user out when done. This worked quite well.
However, a few days ago, this stopped working; logging out or trying to switch now leaves me with a blank black screen, without even a mouse pointer (but not off, the backlight is on).
EDIT: To clarify, this is an issue that only affects the GDM login screen, but that affects it whenever it is used, wether it is on boot (when not set to autologin), after logging out, or when trying to switch user.
At this point, I can usually use Ctrl-Alt-F1 to get a textmode login, and Ctrl-Alt-F7 to get back to the auto-logged in session (assuming I tried to switch, not logout).
I can't think of anything specific I did or installed around then that should be related in any way...
I tried disabling autologin and restarting gdm, which left me with the same black screen (which is still there after rebooting), instead of the expected login window. I managed to re-enable autologin by manually editing the /etc/gdm/custom.conf file, so that it would at least work for mom.
I've also tried to change which user is auto-logged in, thinking it might be a problem with my user account, but both users get an automatic session just fine when I restart gdm.
I thought it might be a problem with the video driver, but that's not the case - if I run zenity --info as root with DISPLAY set correctly, the dialog box appears on the screen just fine. It has no borders or titlebar (there's no windowmanager), and is apparently without keyboard focus, so since there's no visible mouse pointer I can't click the OK button... But since it appears, X is apparently up and running just fine, just has nothing to display other than a black background.
I tried purging and reinstalling gdm and gnome-session(-bin|-common), but that didn't help any.
Running ck-list-sessions after trying to switch indicates that there's a new session there, with session-type = 'LoginWindow', so it appears to think everything's fine.
Enabling debug output in the /etc/gdm/custom.conf file did get me some more debug output in the gdm logs, but it didn't really tell me anything, there weren't any obvious problems that I could see.
After some looking around, I've guessed that it's supposed to be running gdm-simple-greeter, which I assume would display a login box; trying to run it manually doesn't work though (it's missing some environment variables, and trying to add them based on the abovementioned debug output doesn't really help).
I've searched the web and these forums and I don't seem be the only one with this problem yet I couldn't find a cure for it; 2 users are logged in, one of them logs out and the screen goes blank. Nothing works except shutting off the computer manually.Does anyone know if a cure has been found for this problem by now?

When I enter my normal user name and password, the screen blinks, a black page appears and after a couple of seconds I get the login screen again. I deleted /tmp files but no changes. I tried to login using command mode. So I hit Ctrl-Alt-F1 and log into root in command mode, then ran init3, then switched user to my normal user and ran startx. It worked and I logged into my normal account, but I can not do this process every time. So, what is the problem? How can I solve this problem? I used to work with my normal user flawlessly. I installed a bunch of software and also copied some folders to my home directory, but I don't know whether these activities caused the problem or not. I'm using KDE4 under openSUSE 11.2.

View 4 Replies View RelatedWhen playing a video file, the system suddenly "crashes" and loads the switch user screen, as if I had selected a different user in the switch user/shutdown panel at the top right of the screen. This seems to most commonly occur with .mp4 files, but also occurs with .avi. I have gotten this problem while playing videos in Totem Movie Player, VLC, and Banshee. My system has 4GB of Ram and Intel Dual Core T4200 processor (2.00 Ghz).

A simple integrated card, but should be enough for watching videos. Perhaps a driver upgrade is what I need.

I was messing around with the screen orientation and thought it would be funny to orient it sideways. 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.

View 1 Replies View RelatedI've been running Ubuntu Maverick as a fresh install since release, and for the last 2 days, I'm having to log in twice! This is only on a locked screen, not on reboot or switch users. After the first login, I see the desktop for a second, then the screen goes blank. I wiggle the mouse and the login screen is there again. The 2nd login goes as normal.
I have gradually been installing things as I need them over the week since install, but I can't pin it down to any of those. It's getting pretty annoying when the screen saver kicks in!
i have noticed that if vista is not the active partition, hybernate does not work. it just goes black and then back to the user icon screen to log back in. another "slight" problem was that i was not able to apply a service pack. after restoring vistas dominance i was able to install the pack. is there any other work arounds for hybernate? even though you might not be interested in cleaning up after microsoft.

I have 4 HD. Primary drive has Windows Vista, Secondary no OS installed. Sata1 HD Ubuntu 10.04, Sata2 Windows 7. Prior to installing windows 7 all was perfect but once I did it, grub got all screwed up. The only way I can boot into grub is if I manually select my Sata1 which has Ubuntu on it and only then it allows me to select Linux or Windows OS. How can I change that so it can boot up normally as before? I'm assuming that grub was installed in the primary drive which has vista on it, but once I installed windows 7 it got deleted and when I tried reinstalling Ubuntu, the grub was not installed in the primary drive.
I have spent the better part of 2 days perusing these forums for assistance. Here is the short story:I run a 7 year old custom build with a 82865G Intel Chipset and a NVIDIA FX5200 graphics card. Had been running a sluggish XP and after adding 2GB of fresh RAM wished to start fresh with my old friend, Ubuntu.
I've tried 10.04 LTS with and without my NVIDIA card installed with no luck. I have successfully installed 10.04 using the alternate install, but this also goes to black. I can hold shift to see GRUB and play around there, but no luck so far. I've also tried 9.10 but have not gotten past the pulsing Ubuntu image. I've seen plenty of support for NVDIA and Intel onboard graphics chips suggesting boot commands like nomodeset and i9015.modeset=0/1...it's all falling short.
I'm heavily leaning towards just installing an earlier LTS or a different linux distro all together. If there no one can help me debug, maybe someone can suggest a distro that will make me happy.
I've installed ubuntu 10.04 onto my Dell Latitude e6510 (through the wubi installer), but I can't get anything except a black screen. I'm pretty new to ubuntu, but after a bit of looking around at graphics issues I found a bunch of boot parameters and tried different combinations of them. i915.modeset=0 Gave me the purple loading screen, until the screen went black and I got flashing caps lock and scroll lock lights.xforcevesa gave me a completely black screen -- not receiving power at all
I also tried noapci, acpi=off, irqpoll, and pci=routeirq as parameters. None of those had any success.I've also tried letting ubuntu boot with a black screen until I heard the African drums and pressing Ctrl+Alt+F1 to go into the console, but the screen stayed black then as well.
I have downloaded Last version of Ubuntu 11.04 and installed it. The installation went correctly with some flickering in display during installation. But the real problem starts after installation, when I turn on my PC and select Ubuntu from GRUB, the screen flickered a lot and then went black and PC got hanged.

View 6 Replies View RelatedAfter the upgrade from 9.10 to 10.04 resulted in a black screen after reboot, I decided to don't waste more time, backed up my data and made a fresh installation.
First Issue [solved]: After I inserted the Kubuntu 10.04 Live-CD and started the system, I got to the CD's boot-mode selection menu. When I selected "Install Kubuntu", I got the Kubuntu bootscreen, but the system hang up then. I was able to solve this problem through pressing F6 in the boot-mode selection menu and setting "nomodeset". I also had to remove "quit splash" from the boot-entry line. Afterwards the installation process was fine.
Second Issue: I wanted to boot my new installated system, but, off course, got the blank screen again. So I edited the Grub-entry for recovery mode in the grubmenu (replaced "quit splash" with "nomodeset") and booted into recovery mode. I selected "netroot", and installed the proprietary nvidia-drivers with "apt-get install nvidia-current". Afterwards I ran "nvidia-xconfig" to generate the xorg.conf. To solve the blank screen issue, I edited the /boot/grub/grub.cfg the same way I described above and rebooted. Now I don't get a blank screen anymore, but I also don't get an XServer. The system boots now (off course without splash and "unquit"), but drops me into the tty1... When I type "sudo service kdm start", I get into KDM and can login, but I get many errors and crash-reports there. I also don't have any internet. I only have internet when booting in recovery mode and select "netroot".
I'm a bit surprised that Ubuntu released a LTS-Version that causes so much trouble (I've searched the forum and it seems that I'm not the only one with such big problems). Has Ubuntu droped support for NVidia-users?
I tried to install Ubuntu 9.10 on one of them by default installation. For the moment there is only one user declared. The installation seems OK, except that Ubuntu didn't find my PPPoE connexion. When I logged in, I got a blank screen with the mouse cursor (it moved, but when I left or right-clicked nothing happened) and on the left something looking like two 1-pixel wide menus, as if the system had understood there were a dual screen. These menus could roll and unroll, and I think I even once managed to shutdown by going to the last invisible item thanks to the keyboard arrows (I'm not sure, because I had also clicked on ctrl+alt+suppr, so it could be a delayed effect of that).
I restarted the computer several times, to get no more than that. When I'm in Gnome safe, everything is OK but I don't have any root privilege there (I guess it's normal): for instance, I can't set up the internet connexion. My 20" 4/3 Philips screen is recognized. Then I changed the screen frequency: it's still OK for Gnome safe session, but now, in the Gnome normal session, instead of a black screen with 1-pixel wide menu, I get a black background picture with white light coming from above and reflecting to an otherwise invisible floor. The mouse cursor is moving, but this is the only thing which works.
Last weekend, I upgraded my old PC and installed Ubuntu 9.10 on a brand new pc. It worked perfectly for 5 days. When I got home tonight, it wouldn't boot and got stuck on a black screen.

I really am a newby here but I think that the blkid command gives me my uuid. The uuid in the /dev/disk/by-uuid directory is in blue so I'm guessing that this is a symbolic link. And then, when I try to create a symbolic link with the ln command, it already exists... But the issue is that the UUID that is referenced in the error displayed is not the same as the UUID in my /dev/disk/by-uuid directory.
So I decided to upgrade from 9.04 to 9.10 today, I was quite sure there wouldn't be no problems. Well, at least not in the installation, and apparently the system works well too, but there's just one thing...When I boot to the new kernel (2.6.31-19), it does show the new white Ubuntu-logo, but after it's gone, some text flashes through extremely fast, and after that the screen turns black, having two small and white horizontal lines on top of the screen. Soon after this, I can hear the login-window sound. I can log in by pressing enter, and then typing my password, and soon after I press enter again, I can hear the login sound. But still, the screen is black, having those same white horizontal lines on top of the screen, making the use of computer "quite" hard.Right now I'm using the older kernel, but the problem is that the sounds won't work, the resolution is still low like when I had 9.04 (problems with Intel hardware), and CD's won't still be read when inserted into the CD-drive.Here's my "lspci" in case someone wants to know of my hardware a little:

I just Installed Ubuntu on my PC (win XP-pro) using wubi, by downloading the .iso from webpage and burned it to cd. The installation went fine, but when I login the screen goes black.

I have downloaded the liveCD for 10.04 and this is a massive failure. All I have is about a .25 inch wide space that I have any video of. And this is trying to just run from the disc or trying to do a clean install.
I am getting pretty aggravated and ready to scrap the whole system and re-install 9.10 if necessary. The ONLY thing I see is the new Kubuntu loading screen. Nothing else.
