        <pre>00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI]
Mullins [Radeon R4/R5 Graphics] (rev 05)
I had to change /etc/X11/xorg.conf to Option “NoAccel” “True” to get xorg
start.
EXA not supported.
Old/other kernel same issue. So it’s not the kernel.
X Server version did not change (1.19.6) I can’t find any libs that changed.
I can not figure out which package did this.

Can anyone please recommend how to troubleshoot to find the culprit?
