<pre>Chris, okay, so its partly an X11 limitation, yet meanwhile I am setting
DisplaySizes for both displays:
martin@merkaba:~> egrep -i "using (monitor|initial)" /var/log/Xorg.0.log
[ 9.503] (II) intel(0): Output LVDS1 using monitor section Notebook
[ 9.503] (II) intel(0): Output DP2 using monitor section Extern
[ 9.504] (--) intel(0): Output LVDS1 using initial mode 1920x1080 on pipe 0
[ 9.504] (--) intel(0): Output DP2 using initial mode 1920x1080 on pipe 1
And it even appears to use some display size:
martin@merkaba:~> grep -i "physical" /var/log/Xorg.0.log
[ 9.689] (II) intel(0): Setting screen physical size to 508 x 285
which is neither
martin@merkaba:~> grep DisplaySize /etc/X11/xorg.conf.d/anzeige.conf
DisplaySize 344 193
DisplaySize 531 299
And also it calculates standard DPI value of 96:
martin@merkaba:~> xdpyinfo | grep -i dots
resolution: 96x96 dots per inch
But well if it uses the 24 inch display as compat device, it may even make some
sense. The fonts still looked really small on it. But 1920x1080 on 24 inch is
certainly a much lower DPI than 1920x1080 on 15 inch.
Well, if its something that cannot be solved differently with X.org, I think I
will wait for Wayland and KDE Frameworks / Plasma 5 to deal with that, and use
the KDE setting for now. It works well enough.
So feel free to close the bug report.</pre>
