This hangs X and all user input stops working (mouse, tablet, keyboard..). It does not happen very often so I have not spent any time trying to figure out what is causing it. >I am running the nvidia driver with a 7950 card. It has been doing this for >some time with different versions of the x server and different versions of the nvidia driver. >Hal Dear Hal: Thanks a lot for your reply! I forgot to say the xorg I used is xorg 1.7.6, and I encounter this at every time, if this happens, the input (mouse, tablet, keyboard..) still active, just the cursor can not move to the second screen center, when I using the SW cursor this still happens, whether can I say there is some relationship with xorg code?
