was able to solve the issue by adding a subsection to my xorg.conf file. In the screen section I added "Virtual 3840 1080 ", which is the combined total of both of my desktops.
This is my xorg.conf file: Section "ServerLayout" Identifier "aticonfig Layout" Screen 0 "aticonfig-Screen[0]-0" 0 0 EndSection Section "Module" Load "glx" EndSection Section "Monitor" Identifier "aticonfig-Monitor[0]-0" Option "VendorName" "ATI Proprietary Driver" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true" EndSection Section "Device" Identifier "aticonfig-Device[0]-0" Driver "fglrx" Option "UseFastTLS" "1" BusID "PCI:1:0:0" EndSection Section "Screen" Identifier "aticonfig-Screen[0]-0" Device "aticonfig-Device[0]-0" Monitor "aticonfig-Monitor[0]-0" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 Virtual 3840 1080 EndSubSection EndSection I hope this helps, and there should definitely be a way for ubuntu to either figure out the virtual size for itself, rather than me having to add it in, when it is such a simple calculation -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/858025 Title: amdcccle crashes in 11.10 beta when trying to enable dual monitors To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/858025/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
