I had a short possibilty to borrow the D830 again. I've tried the Kubuntu Karminc beta 1 i386 LifeCDROM and the bug is still there.
After boot the latitude D830 (1680x1050) + Dell 24'' TFT via DVI of the docking station choose on first common resolution: 1152x864. So the fonts are way to big (see attachment 1-xrandr.after-login)
What's different from bug 437173 ss that when I turn of the LVDS, with xrandr --output LVDS --off, that the TMDS does not scale
to 1920x1600 automaticly not does xrandr --output TMDS --auto convince the driver to use the native resolution of the external TFT (that works in the GM45 case).
