Hi how to I'm also experiencig this problem. Was your installation an upgrade or a fresh install? I experienced the same problem on an upgrade but after a fresh install I could log on, but the card now cuts out after a few minutes/secs.
I've tried the fglrx driver but experience the cut out issue. When I get 5mins I'll install the linux non-free firmware and the fglrx updates. The card might need the firmware to run the window system according to the Debian wiki's. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1309969 Title: Garbled display on 14.04 with ATI Radeon HD 7750 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1309969/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
