System freezes after upgrading Xorg server to 1.10
After upgrading Xorg server to version 1.10 I stated experiencing screen flickering and frequent freezes, especially when using KDE4 with compositing enabled.
Most crashes occur when maximizing windows.
The whole system is dead, you cannot even move the mouse.
nv driver work fine.
Also installing old Xorg version 'solves' the problem.
