hello jens,

thank you for reporting this.

it's not so much the log files i'd need but the output of the following
commands:

(i don't know your background, so i'll explain in as much detail as i
assume is helpful)

open a terminal window from the applications menu, and enter the
following lines (you can't paste them to the terminal window with
ctrl-v, but you can use the edit/paste menu for it):

xrandr --query --verbose > xrandr-qv.out 2> xrandr-qv.err

xrandr --query > xrandr-q.out 2> xrandr-q.err

xrandr --verbose > xrandr-v.out 2> xrandr-v.err

xrandr > xrandr.out 2> xrandr.err

arandr > arandr.out 2> arandr.err

it can happen that the symptoms you described occur after one of those
lines, in which case i you don't need to execute the other lines.

don't wait for any output, the lines save their output to .out and .err
files in your home directory, which i'd ask you to attach to this bug
report, along with the log files /var/log/Xorg.0.log and
/var/log/Xorg.0.log.old (the latter assuming you just reproduced the
error and rebooted, i hope that it's the right file then).

best regards

Here are the output files. The Xorg.0.log and Xorg.0.log.old will follow later. At the moment I cannot reproduce it.

All the *.err files were empty files (0 Bytes) which I did not attach therefore.

thank you.

as the outputs don't contain anything suspicious, and as this happens at
startup, i assume that it is plugging-related.

you might be able to reproduce it when you run arandr right after
plugging your laptop into the docking station. if you find a way to
reproduce the freeze, please run the mentioned commands instead of
arandr (as you would normally make the freeze happen) to see which of
those commands triggers the problem.

It seems I cannot reproduce this bug anymore, instead I get a different symtom now (see clip attached). Should I file a new bug?
