I have the same problem in my Ubuntu desktop, then

  • if I change the X.Org X server-Nouveau driver for the NVIDIA one, the display crashes next reboot (even in recovery mode) so only reinstall option remains.

  • the /etc/X11/xorg.conf file doesn't exist

  • the display settings only show 1024x768 and 800x600 resolutions

description: CPU product: AMD Phenom(tm) II X4 955 Processor vendor: Advanced Micro Devices [AMD] physical id: 3 bus info: cpu@0 version: AMD Phenom(tm) II X4 955 Processor serial: To Be Filled By O.E.M. slot: CPU 1 size: 3200MHz capacity: 3200MHz width: 64 bits clock: 200MHz

So, please, these are my questions:

  • Can somebody advice me how can I have a stable ubuntu OS?
  • Some suggestion about configure or add a file concerning to graphics?

Thanks, Gbrunati

  • Try running (if you can) sudo dpkg-reconfigure xserver-xorg and sudo dpkg --configure xserver-xorg. – TheWanderer Apr 21 '15 at 23:28
  • thanks Zacharee, gbrunati@conse:~$ sudo dpkg-reconfigure xserver-xorg dpkg-query: package 'xserver-xorg' is not installed and no information is available Use dpkg --info (= dpkg-deb --info) to examine archive files, and dpkg --contents (= dpkg-deb --contents) to list their contents. /usr/sbin/dpkg-reconfigure: xserver-xorg is not installed gbrunati@conse:~$ sudo dpkg --configure xserver-xorg dpkg: error processing package xserver-xorg (--configure): no package named `xserver-xorg' is installed, cannot configure Errors were encountered while processing: xserver-xorg – Gordiano Brunati Apr 23 '15 at 3:47
  • Oh sorry. It seems like Nvidia replaces the X server with its own thing. – TheWanderer Apr 23 '15 at 10:04

You could try upgrading to the latest:

sudo add-apt-repository ppa:xorg-edgers/ppa -y 
sudo apt-get update
sudo apt-get install nvidia-current

If this doesn't work can you send us the results of lspci -v | grep VGA so we know what card you have.

Also what version of Ubuntu are you running?

  • These are my specs: ubuntu 14.04 LTS gbrunati@conse:~$ lspci -v | grep VGA 00:0d.0 VGA compatible controller: NVIDIA Corporation C61 [GeForce 6150SE nForce 430] (rev a2) (prog-if 00 [VGA controller]) – Gordiano Brunati Apr 23 '15 at 3:37
  • If I try to install NVIDIA, then it will froze when I open and try to use Chrome – Gordiano Brunati Apr 23 '15 at 3:38
