Bug Description
Binary package hint: xserver-
This has been happening in this system ever since the drm changes landed in the lucid kernel. it seems to be related to new_pll .
Initially the problem with the guest session would occur if i start it immediately itself.
But when i used new_pll=0 , it just causes the problem to occur hours later.
Problem also exists with the latest maverick kernel from leann's ppa
~$ uname -a
Linux Aspire-5670 2.6.35-23-generic #34~pre20100922
Which is supposed to have a solution for this problem : <http://
Because of this problem i had been using the mainline kernel for a very long time[.33, .34 and .35], but i have never had this problem with the mainline kernels.
Only with the Ubuntu stock kernel i get this issue.
