Package: xserver-xfree86 Version: 4.2.1-3 Followup-For: Bug #163815 Hi, this bug is very related to the bug I filed (#164446), probably the same problem. Try driver from http://www.xfree86.org/~alanh/, then powercycle (halt and turn the computer on again, without it you won't see the fix). Please report, if it fixed the problem for you.
