I read you Phoronix comment while updating my own copy from 14.04. Personal update went fine while using almost same card (HD 5750.) but was already using radeon driver.
>From what I gather you were using catalyst before update. Any idea if radeon driver worked with older version? X with disabled KMS isn't supported. Your X logs essentially are from trying this. Something to try; Add "modprobe.blacklist=radeon" to GRUB command line. >From terminal; sudo modprobe radeon ; sleep 1 ; dmesg > dmesg.log If no errors startx. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
