To clarify "without docking station" means i) without external screen - or ii) with external screen attached?
If you can do ii) as well, it would be great.
So laptop was not in docking station and external display (DELL U2312M) was connected with VGA cable. Unfortunately, the display was not recognized correctly, so I was only able to set 1024x768 within the KDE display settings applications, although if connected via docking station + DVI the full resolution, which is 1920 is available. I may have to file a new bug
This could be your monitor/cable as well. You should replug it and see if it starts working again. Your chipset is a Hawsell GT2 (PCI dev ID: 0x0416) - the same one I've got here on an HP machine: I have no problems detecting the correct video mode. If you see this issue with a different monitor/cable combo as well, please provide the following: 1. output of 'xrandr -q --verbose' when this monitor is connected. 2. Add 'drm.debug=0x4' to the kernel command line, reboot and provide the output of 'dmesg'.
for that. Anyway, after 4 days and waking up by pressing the power button, the external display showed the desktop again (in 1024).
OK.
Another bug surfaced by doing the above: Now, when in docking station, the desktop is ONLY shown on the external display as well as the laptop display, when the VGA cable is connected. When disconnecting the VGA cable, all screens turn black (so signal). So since I connected the VGA cable once for trying to fix the resume issue, it broke the entire display settings. I tried to remove .kde4 as well as .config, but that didn't help. I guess I need to open a new bug for that?
Yes, but most likely not with me. This looks very much like a KDE issue.
I'm not even sure how to help you over this hump: It is difficult to operate
the desktop configuration tool when you can't see. If KDE still keeps the
authoirzation file in the standard location, you can do the following: log into
your account from remote (this way you will get your authorization file),
change the DISPLAY variable to :0 (export DISPLAY=:0) then use 'xrandr -q' to
query the available outputs. You should see the LVDS and the DVI on the docking
station marked connected. ON the mode lists below you will see the currently
enabled mode marked with a '+'. Pick the mode you want ('*' marks the
preferred, ie. native mode) and do 'xrandr --output
