Hi,
I have a AMD 780 based board (Gigabyte GA-MA78GM-S2H) as HTPC connected to an Panasonic TH42 PX80E (via HDMI).
The box is running under Gentoo with Catalyst 8.10.
X is running with 1280x720 @60 Hz, the TV recognises it as "720p". With Overscan turned off in the TV Menu, I get black borders around the screen (~ 3 cm).
aticonfig --set-pcs-val=MCIL,DigitalHDTVDefaultUnderscan,0 didnt change anything.
After running
aticonfig --set-dispattrib=tmds2i,positionX:0
aticonfig --set-dispattrib=tmds2i,positionY:0
aticonfig --set-dispattrib=tmds2i,sizeX:1280
aticonfig --set-dispattrib=tmds2i,sizeY:720
the black borders are gone!
The Problem occurs at the next Xorg start/restart: Xorg doesnt start any more, I get only a black screen! WTF ?!?
aticonfig stored the position / size changes in /etc/ati/amdpcsdb.
If I delete the changes made by aticonfig, Xorg starts again, but naturally the black borders are there again!
I deleted /etc/ati/amdpcsdb to make sure that this is not a problem with legacy settings from older catalyst versions. After running aticonfig again, Xorg doesnt start. I didnt found any significant error message in the Xorg log.
Does anybody know how
x aticonfig can be prevented to store these settings in amdpcsdb?
x or how could Xorg be persuaded to start in spite of these settings in amdpcsdb?
Thanks,
Dominik
