This would be very helpful for me. You might also try, in nouveau_accel_init: if (device->chipset == 0x96) return; It works without nouveau.noaccel=1 and has no scrambled screen (at least for the GUI and the console, except for a tiny moment of full garbage (boot logo?) but it gets cleared away after), but it is unstable (hanged up some times at boot) and it spams a lot (more than 1600 lines) of nouveau E[PFB][0000:03:00:0] trapped write at 0x0000546000 on channel 0x0000fee0 [unknown] BAR/PFIFO_WRITE/FB reason: PAGE_NOT_PRESENT Strangely, when connecting an external monitor to the laptop (MacBook Pro mid 2009, same cards), the GUI isn't scrambled any more and the console still is, but in a "better way". I'll try to find why with an external monitor or with acceleration on the 9400, the handover goes well. -- You are receiving this mail because: You are the assignee for the bug.
