Thanks for the bug report. We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue. Please attach your X server config file (/etc/X11/xorg.conf) and X server log file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file attachments using the bugzilla file attachment link below. Could you please also try to run without any /etc/X11/xorg.conf whatsoever and let X11 autodetect your display and video card? Attach to this bug /var/log/Xorg.0.log from this attempt as well, please. We will review this issue again once you've had a chance to attach this information. Thanks in advance.
It doesn't even get that far, so it doesn't write any logs: [angenenr@shutdown ~]$strace -ff -eopen Xephyr :2 2>&1 | grep log [angenenr@shutdown ~]$ This is without xorg.conf in place.

Attaching complete strace files: strace -ff -o Xephyr.strace Xephyr :2 Still without xorg.conf in place.
Created attachment 311461 [details] strace -ff -o Xephyr.strace Xephyr :2
Created attachment 311462 [details] strace -ff -o Xephyr.strace Xephyr :2 (second file)
Attaching my xorg.conf and Xorg.0.log (there's no Xorg.[12].log which confirms what Ralph wrote). I can't restart my Xserver now (it's my work machine), so I can't post what happens with an empty xorg.conf file.
Created attachment 311464 [details] Xorg.conf file
Created attachment 311465 [details] X server log file
