Hi,
I’ve been stuck on this problem a while now and have no idea what causes it specifically.
Config is:
HP x360-spectre with GTX 1050Ti,
Ubuntu 19.04
kernel : 5.3.0-46-generic
nvidia-driver-435(proprietary) installed through ubuntu-drivers as default
The problem is:
If PRIME is set on nvidia, after a few minutes (1-2) of no activity, screen would freeze and I am unable to <Ctrl-Alt -fx> to another session. This also happens sometimes by random when there is some activity (I notice that it’s usually when the fans stop). When this happens only thing I can do is hard reboot, so I am unable to run bug-report.
If PRIME is set on on-demand, in the same moments as before, nvidia-smi reports that GPU is lost
(Unable to determine the device handle for GPU 0000:01:00.0: GPU is lost. Reboot the system to recover this GPU
). I ran bug-report prior to that (when gpu is present and driver is loaded) and after that (when gpu is lost) and attached it here as log (pre and post) files.
If Prime is set on intel, no such incidents occur.
Same problem occurred on Ubuntu 18.04, previous versions of linux kernel, and 440(open-source) driver.
pre-nvidia-bug-report.log (2.0 MB)
nvidia-bug-report.log (2.4 MB)
I am mainly using nvidia GPU for cuda and tensorflow and I managed to get that working during those brief moments when GPU is present and driver is loaded. However, I am unable to make it work consistently over long periods.
Any advice/help is appriciated.
