- I can't seem to get it so that the VGA monitor is at e.g. coordinates -1600x0, so it doesn't affect the contents of the LCD. My CRT is on the left side of my desk where the laptop is on the right, so it would be useful if I could somehow get the CRT to simply use negative coordinates instead of having everything move over to the CRT when switching to multiple monitor mode.
There are no negative coordinates. You can, however, move your panel to the right (xrandr --output PANEL_LCD1/LVDS/TMDS --right-of VGA_CRT1/DAC_A). Theoretically, --left-of should produce the same result, practically there are some bugs lurking in RandR.
It seems that this is also an issue with the Intel RandR 1.2 driver. There's a thread about it on the X.org mailing list[1], and it seems that it has to do with the fact that LVDS is on CRTC 1 while VGA is on CRTC 0. The old non-RandR Radeon driver had an option "MergedXineramaCRT2IsScreen0" that allowed the Xinerama screen IDs to be flipped, but I'm not sure if this is applicable to RandR 1.2.
