http://i.imgur.com/qi14xgu.png

I have the problem that maximized windows use only what looks like the top-left 1024x768 pixels.
I think that's also the area used by the boot screen.

Actually it's a little more complicated: It depends on the original position and the size of the window whether it maximizes to the full screen or the smaller area you see in the screenshot. Even that is inconsistent: smplayer needs to be partially in the area and partially outside on the bottom-right, youtube videos in chrome need to be completely outside, ...

What's going on here? Where should I start looking? Kernel or Xorg config?


edit:

Code:
sisyphos@sisyphos ~ $ xrandr
Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 32767 x 32767
LVDS1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
   1024x768       60.0*+
   800x600        60.3     56.2 
   640x480        59.9 
VGA1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 477mm x 268mm
   1920x1080      60.0*+
   1440x900       59.9 
   1280x800       59.8 
   1152x864       75.0 
   1024x768       70.1     60.0 
   800x600        60.3     56.2 
   640x480        66.7     60.0 
   720x400        70.1 
DVI1 disconnected (normal left inverted right x axis y axis)
TV1 unknown connection (normal left inverted right x axis y axis)
   848x480        59.9 +
   640x480        59.9 +
   1024x768       59.9 
   800x600        59.9 
VIRTUAL1 disconnected (normal left inverted right x axis y axis)


Sadly I have no idea how to read that.

edit2:
Code:
xrandr --output LVDS1 --off
seems to have fixed it, although I still have no idea what is going on.

You are probably using your notebook with the screen lid closed. The way that that works, is that the screens are displaying the same image, but your external monitor has a greater resolution. When you hit fullscreen, mplayer or whatever is using the lowest screen resolution as "fullscreen". So you have a fullscreen video on your notebook, and a borderless "window" on your external monitor.

I'm on a normal desktop PC. Do you know what LVDS1 is, how I can add a full resolution mode or whether I need it at all and what for?

LVDS is the conector used on laptop screens, that's why I supposed you had a desktop. Just turn it off, it's your driver somehow misinterpreting it's presence:
xrandr --output LVDS1 off
or something, don't quote me on that.

Do you have an idea how I can turn off LVDS1 for good? Via xrandr I have to repeat the command every reboot.

You use KMS? Add video=LVDS-1:d to kernel command line.
