Description me.mark 2014-09-03 21:11:18 UTC
Hi,

I recently installed opensuse 13.1 on two machines (one old, one new). I am unable to "switch users" on the new machine, but it works fine on the old machine. I get the following error in /var/log/Xorg.1.log:

[449668.708][449670.362] (EE) mga: The PCI device 0x534 at 10@00:00:0 has a kernel module claiming it.
[449670.362] (EE) mga: This driver cannot operate until it has been unloaded.

I was on mga version 1.6.2, but I updated to 1.6.3 provided on an opensuse forum (https://forums.opensuse.org/showthread.php/500676-opensuse-13-1-KDE-switch-user-fails-returns-to-and-locks-current-session?p=2662667). Version 1.6.3 did not fix the issue.

Am I missing anything? I included some relevant info from /var/log/Xorg.1.log below.

Thanks!

I emailed Tilman Sauerbeck (the current default assignee on MGA bugs). He let me know that he no longer works on MGA and believes there is currently no development on it. He did suggest that I get a different video card, however. This makes sense to me because I didn't buy a dedicated video card.

Hope that helps someone else.
