High CPU usage in Mint

[devils casper]

Hi and Welcome !

Have you executed top command to check which process is taking most of CPU Cycles?

[DiFS]

Yes I did it, and it is Xorg.

It looks like Hardware drivers option haven't installed correct driver. Re-install Driver using envy. Its available in Ubuntu Sources.

sudo apt-get install envyng-gtk

Either use its Graphical Interface or execute envyng command in Terminal. Remove existing driver and re-install again.

Sorry Casper, I was using Vista for not overload the CPU, but I start Mint again, Xorg is using 10 - 15 % of CPU, even if firefox open. It is the correct value?
Thanks.

Hi Casper,
I still have problem with Xorg. I installed envyng and removed the drive. I installed recommended drive ( old version ), but the problem persist.
Do you have any more idea?
Thanks.

I had similar problem with Linux mint 7. I usually like to stay one release behind on what ever distro I am using in order to avoid immediate release bugs.

anyways.

When you go to Start (menu) > Administration > Hardware Drives.

It recommends that you use NVIDIA drive (version 180) [Recommended]
So that is what I did. So I noticed that my cpu never droped below 50% in Idle.

I went back and changed the driver to NVIDIA driver (version 173).

since then my idle CPU is around 3 to 5 %.
