[Bug 1007765] Re: brightness adjusting crashes system

 

Hello to you all!
I am showing up here because I have the same issue. I found this thread this morning after blaming the hardware on my notebook for a year but rethinking this to be a software issue this morning. I will try out the solutions here to contribute on this this evening.

Please, how are the actual informations on pinning down this issue to a
subsystem?

What I want to contribute at first is technical stuff. I have exactly
the same issue on this constellation (all tried out in 2013):

Dell Studio 1558 with BIOS A04 and A12, HD4500 ATI 
debian or archlinux installed
several installed linux-3.1n.x versions
several recent fglrx catalyst legacy drivers
several recent open source radeon drivers

Yes, no ubuntu launchpad issue at all!

Yes, all the same crash but the pattern on screen after crash is
different: fglrx is flashing a couple of chars in the pattern, radeon
displays a mor simple pattern with no flashing chars.

Kind Regards
Konsti
