Gt 710 with nouveau
Manjaro Xfce fully update
kernel 5.4 and 5.9
basicaly in 50% of the cases it fails to start X, even startx from console fails
this is a clean install, nvidia proprietary drivers have never been installed, no hardware change (already said it’s a clean install)
Xorg.0.log doesn’t really say much when it fails

this is what I see when it fails.
full log: Xorg.0.log - Pastebin.com
dmesg between when it starts and when it fails has only a minor difference (this log is from when in works, DRM loaded at 5,0, X ended up at the DRM part at 5,6 so no issues):

the part that you see here at 5.00 it’s at 5.70+ when it fails. Compared to my other machine with a GT 1030 the DRM part is considerable slower, on the GT 1030 there is no 1,5-2 seconds delay, it basicaly follows in under 0,2s
lspci -knn (it’s the same in both cases, when it works and when it fails)

I kinda understand that it fails because the DRM part is not really loaded when X tries to start. What I don’t understand is why it takes so long…
I can wait as much as I want it will still be a nice blackscreen. Droping to console and trying to start X result in a failure. Only thing changed in the Xorg.0.log is
parse_vt_settings: Cannot open /dev/tty0 (Permission denied)
DRM part is already loaded in dmesg.
Any suggestion on how to speed up the DRM part that is lagging?
Alternative how do I add a delay before X starts? Hopefully the DRM part will be loaded by then…
