I suffered from the fglrx SRU in 12.04 too. Being forced to fix the problem I tried the saucy enablement stack (https://wiki.ubuntu.com/Kernel/LTSEnablementStack). In order for radeon to work properly, fglrx has to be uninstalled. I had to blacklist the vesafb driver, otherwise I'd get a GPU lockup during boot.
WARNING: fglrx-8.x is incompatible with the saucy stack! In order to operate fglrx-8.x after experimenting with the saucy enablement stack, one has to downgrade back to the precise stack (kernel+X11+mesa). I was positively surprised by the performance of the open source radeon driver in saucy. 3D unity performance is on par with the fglrx, while things which did not work before (e.g. DVI output on docking station) work now like a charm. I don't do gaming on the laptop, so I can't tell how well the open source radeon driver performs with 3D in general. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1276379 Title: fglrx-installer 2:13.101-0ubuntu0.0.1 fails with some "legacy" devices (Radeon HD 2000 3000 4000) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/1276379/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
