I’ve tried that option and server sees it:
[ 42.095] () NVIDIA(0): Option “ConnectedMonitor” “CRT-0, DFP-1”
[ 42.095] () NVIDIA(0): ConnectedMonitor string: “CRT-0, DFP-1”
But this doesn’t help. I still get the skips and EDID spam in /var/log/Xorg.0.log
HOWEVER, after even more testing, I finally found what’s causing this.
Turns out, having the “GPU” meter enabled in gkrellm (version 2.3.4) makes it run:
nvidia-settings -q ‘[gpu:0]/GPUCoreTemp’
every 5 seconds. And when that happenned, I got this full stop of Xorg for a short while.
In fact, each time I run nvidia-settings interactively or nvidia-settings -q GPUCoreTemp, I got that spam in Xorg.0.log.
So I checked nvidia-settings version:
nvidia-settings: version 280.11
So I’ve packaged a newer one:
nvidia-settings: version 313.18
…and the problem looks like fixed. I’m going to reboot some more and test things now, wish me luck.
