@Pali: I am glad it worked for you, but this is not an acceptable solution for less technical users who just want Ubuntu to work straight after boot.
I currently dual boot with Debian unstable, which is running kernel 3.13, mesa 10.1, xorg 1.15 and GNOME 3, and I have none of these problems. Both the opensource and proprietary drivers worked painlessly. I don't know whether the probblem comes from Unity itself or the patched kernel that Ubuntu runs, but, as of today, I cannot use the opensource driver because of this bug and cannot use the proprietary driver because Unity refuses to load (same as reported here: http://www.phoronix.com/forums/showthread.php?93838-Ubuntu-14-04-Kernel-3-13 -and-AMD-Catalyst-issue). The only option that works is with nomodeset (Unity running software acceleration), great ! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1301839 Title: AMD Radeon HD 8670A/8670M/8690M[1002:6660] Low-graphic mode with Trusty To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/1301839/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
