Some notes which might help various people. AMD Catalyst (fglrx) 13.1 was released in January 2013 and brought official support for X.Org Server 1.13 and "production support" for Ubuntu 12.10.
Anyone with AMD Radeon HD 7xxx graphics and wanting to use the open- source driver instead of fglrx will need at least kernel 3.9, although it is faster with later kernels. Ubuntu 13.10 "Saucy Salamander" is based on the 3.11 kernel. Although support for hybrid graphics arrived in the 3.5 kernel (when used with xserver 1.13), runtime power management support was not enabled on ATI/AMD Radeon graphics hardware until the 3.13 kernel - it has support for dynamically powering down discrete GPUs on PowerXpress systems - see http://lists.freedesktop.org/archives/dri- devel/2013-November/048316.html and http://lists.freedesktop.org/archives/dri- devel/2013-September/045650.html for details. Ubuntu 14.04 "Trusty Tahr" now has the 3.13.0-12.32 kernel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1069199 Title: 1002:682f Unity does not start after installing fglrx-updates Radeon HD 7700M Series To manage notifications about this bug go to: https://bugs.launchpad.net/fglrx/+bug/1069199/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
