Kalandozó ATI felhasználó, második rész: a radeonhd meghajtó

Újraindítás után a két megjelenítő jó dolgozik össze, egymás mellett lévő munkafelületként viselkedik, így simán áthúzható az egyik ablak a másikra. Megjegyezendő, hogy a modern xorg.conf szemléletnek megfelelően a konfigurációs állomány egy Device bekezdést használ. Az ablakok kezelését xrandr segítségével oldom meg.

Elrettentésül, például, segítségül és kijavítandó feladatnak közlöm a jelenlegi xorg.conf állományomat:

# xorg.conf (X.Org X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the xorg.conf manual page.
# (Type "man xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.

# If you have edited this file but would like it to be automatically updated
# again, run the following command:

Pár beállítás azonban itt csak a radeon driver öröksége, azaz nem úgy működik radeonhd meghajtó alatt. Ezeket a X.org nem veszi figyelembe. Például a HDMI kimenetet beállító részt a radeonhd driver egyszerűen más néven nevezi:

DVI-D_1 connected 1920x1080+1440+0 (normal left inverted right x axis y axis) 708mm x 398mm
   1920x1080      50.0*+
   720x576        50.0  
   640x480        60.0  

A fenti példafájlban már átírtam a kimenetek elnevezését. Sajnos köztes felbontást nem sikerült elérni a HDMI kimenet számára. Mondjuk a 1360x768 felbontás lenne a cél. De a HDMI kimenet képátvitele így is jól működik, videot jól lehet rajta nézni, hang azonban még nincs sajnos.
