running x as root

debian sid

these 2 variables are set in ~/bashrc
Code: Select all
mac ~ # echo $XAUTHORITY
mac ~ # echo $DISPLAY

but to run an x app in root, i constantly have to do
Code: Select all
mac ~ # rm .Xauthority
mac ~ # cp /home/<user>/.Xauthority . -v
'/home/<user>/.Xauthority' -> './.Xauthority'
mac ~ # xauth generate :0 . trusted
mac ~ # gparted
libparted : 3.2

what has changed that is causing this?

I have no need to run any X apps as root. :? Something is wrong with your habits, not your Debian.

This needs root permissions to access /dev/dri/card0
Code: Select all
[    78.097] (II) Initializing extension DRI2
[    78.106] (II) modeset(0): Damage tracking initialized
[    78.106] (II) modeset(0): Setting screen physical size to 338 x 253

systemd takes care of the permissions AFAIKT from the contortions I've seen wrangling with X on sysv in stretch. It's not the same in testing and sid - but it's probably similar when running systemd.

check the X log to see if it helps locate it -
(check the date ls -la of files in .local/share and /var/log to make sure it's the current log )
- or check systemd for how it handles X permissions.
good luck with the mac stuff too - ever dive into darwin at all?
I looked inside a few times when they first released.
