Comment 19 for bug 85449

I can confirm this bug but my problem is a bit different from what has been described above.
Here is my card description:

01:00.0 VGA compatible controller: nVidia Corporation NV11DDR [GeForce2 MX 100 DDR/200 DDR] (rev b2) (prog-if 00 [VGA])

Problem 1:
X refuses to load and shows a screen with B&W bars blinking.
Switch to another session (Crt+Alt+F1) and then switch back to the current session (F7) solves the problem but I have to do that every time X is loaded/reloaded.

Problem 2:
The 9639 driver causes artifacts on alpha channels. I can't fix this problem.

PS: Just for the record, it does matter if all extensions are disabled or enable, the problem persists.
