Dell Inspiron E1505 screen freezes frequently
I am using Ubuntu 11.10 with Gnome shell in my Inspiron e1505 laptop.
Intel Core 2 Duo Processor T7200
ATI X1400 graphics card
My problem is frequently, the screen freezes completely. Only the mouse pointer can be moved, no click or other interactions. Restarting gnome-shell or display manager does not fix the problem. I have to reboot system to clear the problem.
I tried gdm instead of lightdm and the problem is the same.
To try my luck, I installed 12.04 alpha and the problem is still there.
Although, when I used Fedora in the same laptop, I didn't have the problem.(but I prefer to stick to Ubuntu)
Please any suggestions or solutions.
