I have been trying to find a solution to the problem. First I thought Nouveau might be the problem. So I uninstalled and blacklisted Nouveau and started X again without a driver. Still the problem persisted. After that I installed the Nvidia 290.10 driver from the Nvidia website successfully, but still the problem was there. Next, I tried to downgrade Xorg/xserver, following the advice of this thread on page 5 http://forums.debian.net/viewtopic.php?f=6&t=69341&p=397479&hilit=xorg+cpu+wheezy#p397479, which resulted in a broken X system. I reinstalled X, deleted the Nvidia driver and now I am back on Nouveau, with still some occasional sluggishness.
Now my question is if there is any way to configure Xorg to use less CPU, or what issues might be causing Xorg's high CPU load. According to htop this instance is causing the CPU load;
- Code: Select all
/usr/bin/X :0 vt7 -br -nolisten tcp -auth /var/run/xauth/A:0-eHlQEa
