    one screen of 3 blacks out

    I have just switched my work pc to Ubuntu (gnome) from Gentoo and am having a strange issue.

    I am running Xinerama across 3 monitors, using 2 video cards:

    Screen 1 (left) is a PHILIPS 109B6 (CRT-0)
    Screen 2 (middle) is a PHILIPS 109B6 (CRT-1)
    Screen 3 (right) is a HP L1740 (CRT-0)

    Screen 1 is running on a Quadro NVS 50 PCI
    Screens 2 & 3 are running on a GeForce 7100 GS (dual card output)

    I left the computer on last night and when I arrived in the morning and turned the monitors on,the 1st screen (left monitor) had no X output (black screen, could see no background or windows), except I could see the white cursor moving in the screen if I moved the mouse to that screen.

    I restarted X and the left monitor came back.

    I then did an hour of work and stopped to make a cup of coffee... when I came back, it had happened again

    I will attach my xorg.conf below in case it helps.

    Any thoughts would be appreciated.

    Cheers,

    Ding
