    Default Mouse freezes on right side of screen after video card install

    I just installed my ATI 4850x2 video card using the directions on http://wiki.cchtml.com/index.php/Ubu...allation_Guide

    I restart my computer like it said. When Ubuntu loaded, my mouse kept freezing when it reached the right side of the screen. Ie, where the scroll bars for applications is. It stops for a few seconds and is able to move again. But whenever I bring my mouse back to the right side of the screen it behaves this way. It's very annoying and I cannot find any solution to this.

    This is my xorg.conf file:

    Code:
    Section "ServerLayout"
            Identifier     "aticonfig Layout"
            Screen      0  "aticonfig-Screen[0]-0" 0 0
            Screen         "aticonfig-Screen[1]-0" RightOf "aticonfig-Screen[0]-0"
        EndSection
    
        Section "Files"
        EndSection
    
        Section "Module"
        EndSection
    
        Section "Monitor"
            Identifier   "aticonfig-Monitor[0]-0"
            Option        "VendorName" "ATI Proprietary Driver"
            Option        "ModelName" "Generic Autodetecting Monitor"
            Option        "DPMS" "true"
        EndSection
    
        Section "Monitor"
            Identifier   "aticonfig-Monitor[1]-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:4:0:0"
        EndSection
    
        Section "Device"
            Identifier  "aticonfig-Device[1]-0"
            Driver      "fglrx"
            BusID       "PCI:5:0:0"
        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
            EndSubSection
        EndSection
    
        Section "Screen"
            Identifier "aticonfig-Screen[1]-0"
            Device     "aticonfig-Device[1]-0"
            Monitor    "aticonfig-Monitor[1]-0"
            DefaultDepth     24
            SubSection "Display"
                Viewport   0 0
                Depth     24
            EndSubSection
        EndSection

    I set up a computer for my father using an r600 and fglrx, through the hdmi output. I had the same issue you described. It was a case of the computer wanting to extend the desktop on to the second monitor (which wasn't there).

    Unfortunately I only got it working after a fresh install. Maybe there were some remnants of the older fglrx version causing trouble.
