- As noted on github, GDM needs different parameters for X.
- Making xserverArgs a true list instead of concat-string helps to
filter it and it feels more correct anyway.
- Tested: gdm+gnome, lightdm+gnome. There seems to be no logout option
in gnome, and gdm doesn't offer other sessions, but maybe these are normal.
It was lacking the dbus configuration to bind to
org.freedesktop.DisplayManager, and it was passing fixed TTY/display
numbers to the X server (see 9be012f0d4).
- added numlock on boot switch
- simply add :
services.xserver.displayManager.sddm.autoNumlock = true;
to configuration.nix and sddm will start
with numlock enabled.
These options allow setting the start and stop scripts for the display
manager. Making these configurable is necessary to allow some hardware
configurations. Upstream ships empty scripts by default, anyway.
The most complex problems were from dealing with switches reverted in
the meantime (gcc5, gmp6, ncurses6).
It's likely that darwin is (still) broken nontrivially.
