I’m on Arch Linux (technically Antergos, but updated daily) with a Sager NP8153, with a GTX 1070 Mobile.
Randomly multiple times a day my screens will go black. There seems to be no rhyme or reason to it, I don’t have to be doing graphics intensive things, even writing in libreoffice or just being in Chrome can cause it. It does seem to happen most often while doing video conferences though.
I’ve checked my GPU temperature while it’s been happening, and have run gpu_burn, but the GPU stays around 47-50 degrees. I also verified that all fans are running while the laptop is on.
In the logs, there’s an error:
kernel: NVRM: Xid (PCI:0000:01:00): 79, GPU has fallen off the bus.
I’ve tried disabling monitor sleeping in case it was acpi (just through gnome power settings), downgrading the nvidia driver from 381.22-3 to 375.66, tried nvidia-beta in AUR, have disabled G-SYNC, flipping, and vblank, and added rcutree.rcu_idle_gp_delay=1 to my grub menu due to a forum post I found, but they seem to have no affect.
I’m at a loss, and imagine it to be a hardware issue, but just thought that I’d check here first. Thanks!
I’ve tried with both a blank Xorg.conf file and the newly generated installed Xorg.conf file from the nvidia installer.
I also tried briefly to get nouveau working, but it wouldn’t launch X so I gave up rather quickly.
I’m using an external monitor, and both screens turn off completely.
Also, I’ve had the laptop for about a year, but the problem just recently started happening…I’d say within the last two weeks.
