Hello all, I've juste installed a new computer and I feel like I'm having trouble with my NVIDIA GPU but it could be something else so I've enclosed detailed output. As you can see in [lspci] output, my GPU is `NVIDIA Corporation GM107M [GeForce GTX 850M] (rev a2)` whose specification can be found in [specs].
The trouble I'd like to solve has the following symptoms: --> Sometimes during booting process, it issues a lot of lines like `nouveau E[ PFIFO][0000:01:00.0] SCHED_ERROR [ UNK06 ]` (see [dmesg] output for full details). This seems to appear randomly: sometimes the computer has to reboot automatically two or three times before being able to boot correctly, sometimes it just needs once and doesn't have nay troubles. --> Some other times, windows appear to stop responding with no reasons. I have to move the pointer off so the window display will unfreeze and then I can put the pointer over again. I've found it seems to be related to lines like this one `nouveau E[ PIBUS][0000:01:00.0] HUB0: 0x000001 0x00000002 (0xbad00100)` in [dmesg]. It starts at timestamp 28.115820. --> Sometimes, even my window manager (Gnome 3) freezes and I have to go to a tty to have a chance to unfreeze it. It doesn't always work then sometimes I have to reboot my computer because it has become absolutely frozen (no mouse, no keyboard, even the keyboard CAPS light responds no more). I'm quite puzzled by this and I don't know whether the last symptom is a bug or a feature (maybe multiple user simultaneous outputs). I've also enclosed for your information my [Xorg.0.log] file and [lsmod] output. One suggested me to share that with nouveau mailing list: maybe you don't have any GeForce GTX 850M to test. I would agree to take time and perform test for you if it can help to improve the way driver nouveau handles recent GPU :) Just feel free to ask any further data you'd need about my configuration. Thank you in advance for you reply and have a good week!
