[Solved] X server sporadically fails to start

SJ · 2019-10-02 15:33:15

I'm using X with modesetting driver on a laptop only with onboard Intel graphics. The server is started automatically with xinit, I have this line in my .bash_profile

[[ -z $DISPLAY && $XDG_VTNR -eq 1 ]] && exec xinit

.xinitrc:

#!/bin/bash
exec i3

.xserverrc:

exec /usr/bin/X -keeptty -nolisten tcp -br +bs vt1

And this is my /etc/X11/xorg.conf.d/20-modesetting.conf:

Section "Device"
    Identifier  "Intel Graphics"
    Driver      "modesetting"
EndSection

I cannot reproduce the behaviour, sometimes starting X throws an error, sometimes not. This is a log from a failed start:

[    22.187] (EE) Server terminated with error (1). Closing log file.

So there are two errors:

[    22.104] (EE) systemd-logind: failed to take device /dev/dri/card0: Operation not permitted

Looking around here it seems that this is not a critical error. I'd like to know anyway how I can solve it.

[    22.173] (EE) modeset(0): drmSetMaster failed: Permission denied
[    22.173] (EE) 
Fatal server error:
[    22.173] (EE) AddScreen/ScreenInit failed for driver 0

And this seems to be the real cause. Other questions here about AddScreen/Screen init failed were answered with "Install the appropriate xf86-video-xxx driver". I tried out xf86-video-intel. It shows the same error.

The issue appeared with systemd 243 and can be worked around by enabling early mode KMS.

The message above the screen failure is relevant, enable early KMS for i915 . While we are already here, your .xinitrc is incomplete for a proper session see the blue note boxes
