Qilz, If xgl is hogging CPU, then you don't have OpenGL direct rendering turned on or your driver does not support it. Try the following and see if you have direct rendering on.
[EMAIL PROTECTED]:~$ glxinfo |grep direct direct rendering: Yes If it is "No" and you believe your driver supports it, then enable it on xorg.conf Section "Module" Load "glx" EndSection --------------------------------------- I have a similar issue where firefox hangs using up max CPU, mostly it happens when you right click to open a link on a new window consistently. Has anyone experienced this on fresh install of gusty with latest firefox?.
