Yes, Catalyst has been the only driver that has been working for me so far. I don't believe the radeon driver was working before either, I remember having a similar problem when I upgraded to 15.10.
Thanks for the debugging tip. However it didn't work. Immediately after running the modprobe command the screens go blank, lose signal input, and then after about 5 seconds the machine reboots. After logging in again, I found that dmesg didn't have a chance to pipe its output to the file either. Definitely seems to be a bug closer to the kernel / drm -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1568429 Title: Radeon won't work with KMS enabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1568429/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
