My laptop incorrectly recognises screen DPI (or PPI, whatever).
Fonts look way to small and antialiasing is not applied as intened.
Manually set DPI for Xorg (not just font DPI).
My correct value is 118x118 dpi.
Providing /etc/X11/xorg.conf OR /usr/share/X11/xorg.conf.d/60-monitor.conf files with options like (none helped):
Editing /etc/X11/xinit/xserverrc to contain line like (strange, but did not help):
DisplaySize 272 204
Option "DPI" "118 x 118"
The things that worked:
exec /usr/bin/X -dpi 118 -nolisten tcp "$@"
Firstly straightforward method of uncomenting /etc/alternatives/lxdm.conf file to override server args like:
did not help as well,
arg=/usr/bin/X -nr vt07 -dpi 118 -nolisten tcp
but after some debugging the solution was found in putting arg value within double quotes, like follows:
arg="/usr/bin/X -nr vt07 -dpi 118 -nolisten tcp"
Alternative solution (found in Archlinux wiki):
And place this string in appropriate startup script (like /etc/xdg/Lubuntu/autostart for Lubuntu) if You like this solution.
