Segmentation fault and complete freeze with GT520
I bought a new graphics card, a GT520 silent. But it seems to make X Segfault when switching VT, not always but usually at least once a day.
I have the 285. drivers installed which had this fix, hoping it would help:
"Fixed a bug causing the X server to crash after a VT-switch while running an OpenGL stereo application which is a member of a swap group."
I have no idea what an OpenGL stereo app would be, I'm just running Gnome 3.2 with two or more X sessions running at the same time. With my old 6200 LE card everything works.
