[gentoo-user] change dpi in xorg

[Michal Kurgan]

Hello!
I want to know if dynamic changes of dpi are possible in xorg, and if yes how 
to do it... here is more specific explanation of my problem.
Recently i had fun with tv-out, i want to connect tv through radeon 9700 and 
fglrx driver, it worked, better or worse. But i found that when i change 
resolution, which is needed in my situation (i use 1280x1024 on crt monitor, 
and tv works on 1024x768 maximal resolution), dpi changes too, fonts are 
smaller, and unreadable, 1024x768 isn't very bad but using this may be 
hard... Also when i add second monitor to x dpi settings changes if i don't 
specify my own setting. I never used smaller resolutions than my default so i 
don't even notice this problem earlier. So there is my question if i can 
change dpi dynamically, i can do it when starting x, with kdm kdmrc file (kde 
3.4.1 version) or DisplaySize section in xorg.conf but this works in "static" 
way, once for one resolution, if i use RandR to change resolution dpi setting 
will be recalculated.
