I turn my display port connected monitor off over night and when I turn it back on in the morning, I get no video (no valid video anyway). This used to happen a while back, then it stopped, now it is happening again.
I find this nonsense in the Xorg.0.log:
... [ 53942.071] (WW) NVIDIA(0): MetaMode [ 53942.071] (WW) NVIDIA(0): "DP-0:nvidia-auto-select{ViewPortIn=1366x768,ViewPortOut=3840x2158+0+1}" [ 53942.071] (WW) NVIDIA(0): could not be re-validated against the current hardware [ 53942.071] (WW) NVIDIA(0): configuration; removing.
It was talking to it fine, but now it wants to "re-validate?" Since the monitor is powered off, it is no wonder it can't re-validate :-).
Any obscure nvidia driver options I can use to make it stop the "re-validation" nonsense?
If I download the EDID and load it from lib/firmware on the kernel command line, will that make the driver happy even when the monitor is off? (Or with nvidia not doing KMS do I need to point at the EDID in the xorg.conf.d directory)
I have no answer for you. But you may want to consider taking this question over to https://devtalk.nvidia.com/default/board/98/linux/
