fix for large fonts in Xorg under -current with intel driver
 

I recently posted a comment in a different thread complaining that xorg from -current with the intel driver gave insane fonts. The reason for the insane fonts was poor reporting/detection of my screen's dimensions (my screen is about 330x210 mm, but it was being reported/detected as 229x21 mm ... the resulting font scaling in KDE made things completely unworkable).

If anyone else is having this problem, a good fix, until the driver itself is repaired, is to set the "DisplaySize" option in your "Monitor" section and also the "NoDDC" "true" option in your "Driver" section. In my case, things look as follows ...

In the monitor section I have added

DisplaySize 330 210 # mm

and in the driver section I have added

Option "NoDDC" "true" # [<bool>]

This seems to have fixed everything.

Note that simply setting DisplaySize is not good enough since the DDC stuff will override whatever you put in for DisplaySize.

***Is it possible to move this thread to a more apropriate place? I suspect that this is a KDE/driver problem, and not a Slackware problem.


I have the same problem now. In Arch Linux 2008.6, I have tried with Fluxbox and KDE, and I have also tried Kubuntu 8.10.

xdpyinfo shows a screen size of 229x21 mm, and a dpi setting that is insanely high. In Fluxbox, I manage to get the menu fonts small by using a ~/.fonts.conf file with a pattern matching element setting dpi to 75.

Below is my xorg.conf.
In Arch Linux, I use the open source radeon driver with an ATI Mobility Radeon Xpress 200M card. (On a HP Pavilion DV5134EA laptop). In Kubuntu, i don't know what driver is used, or what settings.

I have tried the fix suggested in this tread without success. Does anyone have some other suggestion?

Fredrik
