Comment on attachment 741293 [details] var/log/Xorg* and var/log/messages* The method the logs have been acquired: sudo rm /var/log/messages* && sudo rm /var/log/Xorg* THEN, immediately reboot, switch in BIOS to Intel, let system boot and hang. THEN, switch back to radeon, boot up, put the logs in an archive.
The driver I currently use is Catalyst Legacy 13.1 installed per https://ask.fedoraproject.org/question/10924/how-to-install-updated-amd-catalyst-131-for-legacy-chipsets/ The first time I encountered the problem was with Ubuntu 12.04 and Catalyst Legacy 12.6 installed the official way.
It's a closed source driver issue. We can't support fglrx, fglrx bugs should be directed to AMD.
