Bug#618733: x11-common: startx as non-root no longer working
Grumble. I apologize for the noise, I should have been more thorough. Apparently somewhere in the mists of time, while trying to solve things myself, I decided to hand-edit the startx script. And while I did reinstall everything X-related, I apparently did not reinstall xinit itself. A simple sh -x on the startx script showed that it wasn't even trying to run /usr/bin/X... Again, my sincerest apologies for taking your time. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe. Trouble? Contact listmas...@lists.debian.org

Hi Julien, Julien Cristau (jcris...@debian.org on 2011-03-18 10:53 +0100): the -logfile option makes X drop privileges. Ah, that explains what the man page was trying to tell me. From the wording there, I had expected Xorg to bail out with an error, not silently drop privileges.

you're missing /usr/bin/X? Yes, it appears so: aschuring@neminis:~$ file /usr/bin/X /usr/bin/X: ERROR: cannot open `/usr/bin/X' (No such file or directory) aschuring@neminis:~$ apt-file search /usr/bin/X | grep -w X xserver-xorg: /usr/bin/X But that shouldn't really be surprising given that xserver-xorg is not installed. Like I said, reinstalling xserver-xorg does not help, at least not by itself. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

Yet, I have no issues with X when started through my ?dm flavour of the month (currently gdm3). Cue eerie twilight-zone soundtrack... Maybe I'm just misreading this, but from the changelog I had assumed that not having xserver-xorg installed is a valid configuration: xorg-server (2:1.9.4-2) unstable; urgency=low * Put an end to the dependency hell! Now that we have proper dependencies between drivers and the server, remove xserver-xorg from xserver-xorg-core's Depends (Closes: #362313). In a nutshell, one may want to choose between installing: - xserver-xorg-core: the server itself, with no strings attached. - xserver-xorg: pulls the server and drivers, contains the X wrapper and some documentation. - xorg: pulls xserver-xorg as well as various X11 clients and fonts. -- Cyril Brulebois k...@debian.org Wed, 16 Feb 2011 23:17:07 +0100 Nevertheless, the original bug still stands: I can't startx as normal user even with xserver-xorg installed.
