I have strange issue. I use my PC mostly to run some Java app, execute some command line, watch movies and use browser (Chromium), eg. to watch YouTube, play some Flash games and read. Not much more.
Some time ago I spotted some issue with one of the processes taking a lot of CPU and causing low frame rate (2-4FPS or similar, even though the sound is okay) until I restart my machine. The command is as follows, when viewed using
/usr/bin/X :0 -background none -verbose -auth /var/run/gdm/auth-for-gdm-EirVFF/database -nolisten tcp vt7
From http://askubuntu.com/a/179795/18697 it looks like that may have been caused by bad driver or some extra features taking too much processing speed.
From Settings->Details->Graphics I know, that the driver setup is "Intel® Sandybridge Mobile", but I have not found the ability to change that, nor I found any other settings (eg. related to Compiz). According to my PC specs, the card I have is NVidia GT520MX.
I could mess with various configuration files, try to install various external libraries, but I think there is some standard way to deal with that.
How can I fix this problem, so X stops taking so much CPU and the PC works faster?
I applied tips listed here, which came down to typing the following commands:
sudo apt-add-repository ppa:xorg-edgers/ppa sudo apt-get update sudo apt-get install nvidia-current nvidia-settings
But when I run
sudo nvidia-settings, I see the following message:
You do not appear to be using the NVIDIA X driver. Please edit your X configuration file (just run `nvidia-xconfig` as root), and restart the X server.
The problem is, that
nvidia-xconfig is not found in my system, and installing
nvidia-current does not change it.
Any additional clues?
