https://bugs.freedesktop.org/show_bug.cgi?id=27501 --- Comment #28 from Pierre Moreau --- I've made some progress on this bug, enabling Nouveau to be loaded with acceleration enabled. However, X is **absolutely not** usable: complete garbage screen, lots of Nouveau errors, only action available is power down the computer (or reboot). But for using Nouveau with acceleration in console mode, it works fine. There are (at least) two main problems: * 9400M acceleration is broken (resulting in Nouveau locking up on boot); * it seems there is a lockup when starting a working X with both cards enabled. -- You are receiving this mail because: You are the assignee for the bug.
