Okay I'm not sure where I should post this but I'll try here..
I have been running two 17" samsung monitors with VGA connectors connected to my graphics card via a DVI converter.
I have always been able to change the 'primary' monitor with just switching which cable goes into which connector in the computer.
However, I recently bought a 24" monitor to change one of my 17" monitors.. Using DVI with this monitor, I cannot manage to change the primary monitor to this new, DVI-connected monitor, no matter what I do. I always get a lot of tearing in videos, unless i disconnect my second monitor (the 17") which is incredibly annoying. I'm using the nvidia drivers, here are the relevant parts of my xorg.conf:
Section "Monitor"
Identifier "Philips"
HorizSync 30.0 - 92
VertRefresh 50-160
EndSection
Section "Device"
Identifier "6800GT"
Driver "nvidia"
Option "TwinView" "true"
Option "RenderAccel" "true"
Option "AllowGLXWithComposite" "true"
Option "NoLogo" "true"
Option "TwinViewOrientation" "LeftOf"
Option "SecondMonitorHorizSync" "30.0-81"
#Option "SecondMonitorHorizSync" "74.8"
#Option "SecondMonitorVertRefresh" "70"
Option "SecondMonitorVertRefresh" "56-75"
Option "TwinViewXineramaInfoOrder" "DFP"
# Option "MetaModes" "1920x1200,1280x1024;1280x1024,1920x1200"
Option "MetaModes" "1280x1024,1920x1200;1920x1200,1280x1024"
Option "UseEdidDpi" "false"
Option "DPI" "81 x 81"
Section "Screen"
Identifier "Screen 1"
Device "6800GT"
Monitor "Philips"
DefaultDepth 24
Subsection "Display"
Depth 24
Modes "1920x1200" "1280x1024" "1024x768" "800x600" "640x480"
ViewPort 0 0
EndSubsection
EndSection
Any help would be greatly appreciated. Note that what I want is to have the metamodes say "1920x1200,1280x1024", the "TwinViewXineramaInfoOrder" doesn't actually change the primary monitor.
Update: I was thinking that I could change the "Sync to Vblank on display device" in nvidia-settings to my dvi connected monitor, however, that just tells me:
ERROR: The attribute 'XVideoSyncToDisplay' specified on line 50 of configuration file
'/home/insertusernamehere/.nvidia-settings-rc' cannot be assigned the value of DFP-0 (the currently enabled display
devices are CRT-0, DFP-1 on nodame:0.0).
Any ideas why not? Are the nvidia drivers just really bad? :S
