--- Comment #6 from [email protected] --- cat /proc/cmdline returns nouveau.runpm=0 correctly, but optirun glxinfo is still failing with the exact same error and: [ 250.843476] nouveau E[ PBUS][0000:02:00.0] MMIO write of 0x00000000 FAULT at 0x418880 [ IBUS ] [ 250.843564] nouveau E[ PIBUS][0000:02:00.0] GPC0: 0x419eb4 0xbadf1000 (0x3800820c) [ 250.843617] nouveau E[ PBUS][0000:02:00.0] MMIO write of 0x3f800000 FAULT at 0x405804 [ IBUS ] [ 250.843773] nouveau E[ PIBUS][0000:02:00.0] HUB0: 0x404170 0x00000012 (0x0e008201) [ 252.845769] nouveau E[ PGRAPH][0000:02:00.0] HUB_INIT timed out [ 252.845777] nouveau E[ PGRAPH][0000:02:00.0] 409000 - done 0x00000204 [ 252.845787] nouveau E[ PGRAPH][0000:02:00.0] 409000 - stat 0x00000000 0x00000000 0x00000000 0x00000000 [ 252.845796] nouveau E[ PGRAPH][0000:02:00.0] 409000 - stat 0x00000000 0x00000000 0x00000002 0x00000009 [ 252.845799] nouveau E[ PGRAPH][0000:02:00.0] 502000 - done 0x00000300 [ 252.845804] nouveau E[ PGRAPH][0000:02:00.0] 502000 - stat 0x00000000 0x00000000 0x00000000 0x00000000 [ 252.845808] nouveau E[ PGRAPH][0000:02:00.0] 502000 - stat 0x00000000 0x00000000 0x00000000 0x00000000 [ 252.845810] nouveau E[ PGRAPH][0000:02:00.0] init failed, -16 And as for what is concerning PRIME, commenting the AutoAddGPU device didn’t changed anything, except for Xorg.0.log reporting this obviously: [ 136.219] (==) Automatically adding GPU devices It think the issue is somewhere here (from the page you’ve linked): KMS drivers for both GPUs loaded. DDX drivers for both GPUs loaded. nouveau does not load automatically at boot, I need to modprobe it manually. Is there a way to check or ensure nouveau KMS is loaded? -- You are receiving this mail because: You are the assignee for the bug.
