Hi all, |
2 |
|

I'm suffering screen tearing when moving windows around, watching |
4 |
videos, and some other situations. I've tried almost all popular desktop |
5 |
environments, including KDE, gnome(both traditional gnome 2 and new |
6 |
gnome 3), and xfce, the issue always exists except in gnome 3. For the |
7 |
main difference between these window managers, is gnome 3's window |
8 |
manager (mutter) is based on opengl, I think there may be some problems |
9 |
with my card's 2D acceleration. But'cat /proc/mtrr' shows everything is |
10 |
well. |
11 |
My graphical card is Nvidia Geforce GT240M, and I'm using the official |
12 |
Nvidia drivers. |

Does anyone have any suggestions on how to troubleshoot this issue? Any |
15 |
help much appreciated! |
