[[Category:Westminster]]= Objective =
To get my four monitor X-Windows configuration to work properly with Xinerama. Currently, the mouse pointer moves among all monitors, but cannot seem to drag open application window between monitors of differing cards.
= Appearance =
Below are side-to-side screen shots of virtual screen0 (left-hand side) and virtual screen1 (right-hand side)...<br />
Basically, you are looking at what I see across 4 monitors...<br />
Notice spanned wallpaper is repeating for virtual screen0 and virtual screen1.

=== Additional Information ===
'''Xrandr Commands''' (at system startup- Added to "Startup Application"): * <span style="font-family:courier">xrandr --output VGA-0 --mode 1440x900 --pos 1440x0 --screen 1</span> # (right two monitors)* <span style="font-family:courier">xrandr --output VGA2 --mode 1440x900 --pos 1440x0 --screen 0 </span> # (left two monitors) === Other Observations === * Able to get 4 monitors running in XWindows with mouse pointer spanning all 4 monitors (but can't span open applications between cards).* Need to set PCI card as then primary Video default in BIOS to make 4 monitors work (auto didn't seem to work correctly).* When enabling xinerama (i.e. In "Server Layout: '''Option "Xinerama" "1"''' ), screen 0 is mirrored, and does not allow mouse pointer to move to other card (although other card's monitors span correctly. Background picture shows in screen 1, but only background colour displays in screen 0).* '''Radeon error''' upon boot-up: '''error during ACPI method call'''* I seem to have better luck when setting Nvidia card to older driver such as '''"nv"''' ''as opposed to "radeon"''. Unfortunately, also seem to lose better graphics capabilities... Additional information from '''grep radeon /var/log/messages''':
