Two monitor setup:
GPU 0 - Quadro FX 380
DFP-0 + DFP-1: HP LA2405
In xorg.conf (Screen section):
Option "TwinView" "1"
Option "metamodes" "DFP-0: 1920x1200_60 +0+0, DFP-1: 1920x1200_60 +1920+0; DFP-0: 1920x1200_60 +0+0, DFP-1: NULL;"
I have two shortcuts set up in KDE4:
xrandr -s 1920x1200 - To shift to single (left) monitor display.
xrandr -s 3840x1200 - To shift to expanded display across the two monitors.
After the latest f/w upgrade, the command to expand across two monitors no longer works:
xrandr -s 3840x1200
Size 3840x1200 not found in available modes
This has been working well for some 5+ years, so I am unsure as to what the change is.
Any help is appreciated... I need the choice for dual display on command back!
