I have a Dell Precision M4800 with two graphic cards:
- 00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06)
- 01:00.0 VGA compatible controller: NVIDIA Corporation GK106GLM [Quadro K2100M] (rev ff)
My Ubuntu version is 12.04. I am having an issue where the resolution is extremely low, and I cannot change it. I tried to install the NVIDIA graphic card. I went to the NVIDIA website and I found that the version of NVIDIA for my graphic card is 340.96, so I downloaded this version Then I ran these below steps:
sudo apt-get purge nvidia*
2- reboot the system.
3- CTRL + ALT + F1
sudo service lightdm stops
chmod +x NVIDIA-Linux-x86_64-340.96
NOTE- I faced the error that my graphic card does not support this version but I did not pay attention and continue the installation
8- restart the computer
When the computer booted up, the resolution was at the lowest.
9- I tried to run nvidia x server setting but there is this below error:
You do not appear to be using the NVIDIA X driver. Please edit your X configuration file (just runnvidia-xconfig
as root), and restart the X server.
So I did this:
Resulting in this:
Using X configuration file: "/etc/X11/xorg.conf". Backed up file '/etc/X11/xorg.conf' as '/etc/X11/xorg.conf.backup' New X configuration file written to '/etc/X11/xorg.conf'
13- then run this below command to restart the xserver:
sudo service lightdm restart
But the system went black with this error:
Could not write bytes:Broken pipe
And I could not do any thing except shutdown. I would really appreciate it if someone would help. Thanks.
