I had very strange issue , I rebooted my PC (Ubuntu 10.10) , when the login screen comes back, what ever user I select it expands the password field and collapses it again in less than 1 second.
Some services like ssh
, vnc
don't work so I can't login to it remotely, however I can login in tty but still can't login via GDM.
I tried to reinstall gnome via sudo apt-get install --reinstall gnome-desktop
and many other command about reconfigure gnome , but nothing help.
I recorded a video of the problem via my mobile camera (sorry about the low quality )
some of my error logs xserver log
and its the same in the startup error log
:
(ww) warning , couldn't open module nvidia
(EE) Failed to load module 'nvidia' ( module doesn't exist , 0 )
(EE) no drivers avaliable
fatal server error :
no screens found
and now i was stuck in the recovery mode ,
normal mode isn't working any more
2- in the recovery mode + failxsafe : i had tried to create a default configuration for my hardware and after a reboot , with no luck the same problem again .
3-i had tried to reinstall nVidia driver as Jorge suggested in these setps :
sudo apt-get install nvidia-glx-96 /// i took a while
sudo nvidi-setting -r to write new config
and after reboot nothing changed
4- i tried to install sudo apt-get install nvidia-173
and after reboot the same error ,
i ran sudo nividia-setting
and the new error was
ERROR : the control display is undefined , please run
nvidia-setting --help
for usage information
5- beofore this problem i was having this bug , but i wasn't know any thing about it :
Screen Blanks/Monitor Turns Off
Using a laptop with a GeForce Go card, or connecting the sole display via DVI on a dual-head system sometimes results in the screen not receiving a picture. This is caused by the driver outputting video to the VGA port on the graphics card, instead of DVI.
The usual hint that you have this problem is when you hear the startup sound but nothing appears on the screen. If you do not hear any sound, you are more than likely experiencing unrelated problems.
This is a launchpad bug about displays on digital outputs being blank when using NVIDIA binary driver, and can be resolved by editing your /etc/X11/xorg.conf file:
Switch to the console (Try using ctrl+alt+F1, or reboot and select recovery mode from the GRUB menu.)
Use your text editor to open /etc/X11/xorg.conf. (try sudo nano /etc/X11/xorg.conf)
Find the line that says Section "Screen"
Insert a new line that says Option "UseDisplayDevice" "DFP".
Save the file. If you had to restart into recovery mode, type reboot, otherwise restart your display using sudo /etc/init.d/gdm restart.
and i went to vim /etc/X11/xorg.conf
and tada the file is empty .
and ubuntu had backup file called xorg.conf.backup
, so i went to replace it and reboot ....... same error in the video .
Any help or suggestion is really appreciated.
Ctrl + Alt + F1
to enter the command line locally (andCtrl + Alt + F7
to switch back).
