Hi, I switched over from radeohd to radeon/ati for testing and encountered two problems with dualhead setup and xrandr; maybe someone here can me help out a bit.
Setup is as follows: T60 Notebook in docking station (display "LVDS" and resolution 1400x1050) and two external displays via DVI (display "DVI-0" and resolution 1280x1024) and VGA (display "VGA-0" and resolution 1280x1024). Goal is to disable the notebook display and have a dualhead on the two external displays. =1= xrandr initially reports back as maximum resolution 1400x1400 (the biggest screen). For dualhead on the two external display (2560x1024) to small. I have workarounded it by adding a subsection in my xorg.conf: Subsection "Display" Virtual 2560 2560 EndSubsection Just wondering what is needed to autodetect this, because radeonhd set it correctly to this without needing the hint of a subsction? =2= Trying to enable the dualhead on the external displays fails. I disabled the LVDS display via "xrandr --output LVDS --off" and tried to enable the external displays in dualhead mode "xrandr --output VGA-0 --left-of DVI-0". Which does not change anything. After toying around a bit with "xrandr --output X --pos XxY" it seems that both VGA-0 and DVI-0 are modified together when changing a parameter of one, e.g. setting "xrandr --output DVI-0 --pos 100x0" moves both DVI-0 and VGA-0 100 pixel right. What can be wrong here? Versions are (Mandriva Cooker RPMs): * x11-server-xorg-1.5.99.3-1.20081222 * x11-driver-video-ati-6.9.0 Thanks for any help. _______________________________________________ xorg-driver-ati mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-driver-ati
