Posted: Thu Aug 04, 2022 2:33 pm Post subject: Excluding unwired display(s) output from Xorg init? [solved] |
|
|
xrandr returns: Code: | DP-1 disconnected (normal left inverted right x axis y axis) | which is unwired here indeed, e.g. has no output plug. Intel intgrated GPU here.
Any way having Xorg to discard this device? ( i.e. in such a way it doesn't show up in Xorg.log anymore).

I had the similar issue: Xorg.log show 3 monitors connected, though I have only one monitor. I just put this into xorg.conf:
Code: | Section "Monitor"
Identifier "DP-1"
Option "Ignore" "true"
EndSection
Section "Monitor"
Identifier "HDMI-2"
Option "Ignore" "true"
EndSection
|
There may be erroneous ports enumeration in xrandr output, so try different "Identifier" options _________________ GNU is Not Usable |

Interesting...
Once patched for DP-1 here, this device is excluded when xorg-server initializes, i.e. Code: | [ 54.010] (II) modeset(0): Output DP-1 using monitor section DP-1
[ 54.010] (**) modeset(0): Option "Ignore" "true" | which avoids latter previously reported EDID resolution for the same device, i.e. Code: | [ 48.502] (II) modeset(0): EDID for output DP-1
[ 48.502] (II) modeset(0): Output HDMI-1 connected
...
[ 48.502] (II) modeset(0): Output DP-1 disconnected | In this respect, xrandr doesn't refer to DP-1 anymore; which is nice .
Is there any benefit beyond leaner logs and command output, I can't tell.
xorg-server doesn't seem to load any faster enough to impact user experience.
Could be that memory usage being marginally reduced though.
Same for log files.

I used this option exactly for reducing boot time, it helped a lot in terms of booting faster. _________________ GNU is Not Usable |

Out of curiosity, do you initrc, systemd, initramfs?
