Bug 501448 – x11-drivers/ati-drivers-? - aticonfig/amdcccle segmentation fault

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description Jerrod Frost 2014-02-16 06:50:55 UTC]

attempting to use aticonfig with an option besides "--help" causes segmentation fault. Attempting to change resolution on video card using amdcccle and clicking apply/OK causes segmentation fault and resolution remains unchanged. This removes my ability to use eyefinity or my triple monitor setup. All three monitors are stuck in clone mode. 

Not sure if it is related, but Crossfire abilities are greyed out. Possibly because the aticonfig tool cannot even tell how many adapters are in the machine due to segmentation fault any time its used.

Trying to alter the resolution via krandr only causes issues or black screen.


Seems someone may have found the reason behind it and its something to do with finding Xinerama Libraries?

1) Please post your `emerge --info x11-drivers/ati-drivers' output in a comment.
2) Please attach the output of a full backtrace - you quit gdb right before the good bit.[1]
