Adam - According to a few sources via google, yes, and I've tried a kernel with the option for support both enabled and disabled. I'll attach my current configuration file.
Markus - I'm using gentoo. Drivers were installed via emerge ati-drivers. I've tried both stable and unstable/latest with the same result. Stable is 11.3, latest is 11.4.
uname -a output: Linux blackwaterpark 2.6.37-gentoo-r4 #10 SMP Thu May 5 04:28:04 EDT 2011 x86_64 Intel(R) Core(TM) i7 CPU Q 740 @ 1.73GHz GenuineIntel GNU/Linux
I've run aticonfig --initial and rebooted several times to no avail. I will attach my dmesg output with the xorg.conf file that aticonfig --initial generates, as well as my kernel config file.
Just FYI, I've tried several guides from different sites with multiple kernel configurations, etc. which never worked, I'll link to them so you can get a better idea of what hasn't worked. Hopefully it's helpful.
None of the troubleshooting info helped either.
Also, there's been an interesting post in my identical thread over on the gentoo forums. Here's a link: http://forums.gentoo.org/viewtopic-t-876645.html
. The part about the ucode is of particular interest because it's been set up the way the first guide I linked describes, whereas the poster in that forum claims I need to remove all of it. I will go and give his post a whirl and post results/new info here!
Thanks in advance!
