Removing the Modes line (in fact I removed DefaultDepth + Entire "Display" subsection from the Screen Section) had no effect on this. > > When I try to lower the resolution to 1280x1024 using kcontrol, the > > external screen becomes black and a 1280x1024 image is shown only on the > > laptop screen. > > kcrontrol is probably not xrandr 1.2 compliant and probably uses the > old xrandr 1.0 API which only affect one of the outputs and leads to > problems on multi-head systems. Ok, maybe kcontrol isn't up to the job, I have heard before that it does not support xrandr 1.2. I tried to use xrandr manually to change the desktop size using xrandr with --mode and --output options. I managed to get a 1280x1024 resolution on the laptop screen after putting the "Modes" line back into xorg.conf (otherwise 1280x1024 was not listed as a mode for the LVDS). But the desktop image was cropped at the bottom on both screens. I did not manage to get a 1280x1024 "desktop geometry" to correspond to the 1280x1024 screen resolutions on the LVDS and external screen. But I will do some more investigating on how the xrandr command works, I guess there is some way to do it.
