Comment 6 Thierry Vignaud 2011-03-16 15:02:42 CET

Your trace looks like it has been edited (no commands, C line not printed, ...).

Can you do a "print driDriverAPI.InitScreen" from GDB?

Also, if you think this patch fixes it, can you try it?

BTW, Bug #383 is a duplicate.

Comment 8 Thierry Vignaud 2011-03-16 15:05:51 CET

Reinout, you're not using KMS (which is prefered now, still the driver shouldn't segfault when using UMS).
Does it works once you enable KMS?

I don't know why the driver didn't select KMS (I didn't use UMS on purpose) but I'm happy to report that with updated Mageia packages, the problem does not occur any more.
