Rootless X11 in -current
by bl0tt0 from LinuxQuestions.org on (#6DAHB)
I noticed that the newest release of sddm-0.2.0 includes the ability to run it as an unprivileged user, and being curious about how this works on Slackware-current, I decided to give it a test by setting 'DisplayServer=x11-user' in /etc/sddm.conf (I had already rebuild the xorg-server packages with ROOTLESSX=YES). It failed to load, but the sddm.log file was giving the following output:
Code:[17:42:13.838] (EE) HELPER: Failed to take control of "/dev/tty1" ("root"): Operation not permitted

Anyways, I discovered I can get the unprivileged display server to launch by commenting out the /dev/tty1 line in /etc/inittab and rebooting. After that, I was able to launch sddm as the unprivileged user on /dev/tty1 and log in. I had to manually switch to /dev/tty7 to see the session, but thus far it seems to be working well.
If anyone else is interested in running unprivileged Xorg, I would recommend giving it a try and seeing how it works for you too.
