    Dear All,
    I have a problem with X in RedHat 8.0 on several systems.
    I use systems with Intel 845 chipset with onboard VGA and LVDS output.
    There is an Samsung LTN104S2-L01 touchscreen connected to the LVDS output
    and noting is attatched to the vga output.
    I also have an extra CT69000 pic card installed as second display with a 10"
    LCD.

    I've put X & in the /home/myuser/.bashrc to startup X without any Window
    manager. I just want to start my own graphical application as well from
    within the .bashrc

    It seems that in 10% of the reboots, I get a black screen on my LVDS monitor
    although everytinh seems to work fine on the second display.
    X is started and I can see everything when I use X0rfbserver to see what the
    LVDS is showing.

    The problem is that I have got several (30) exact systems like this and only
    +/-5 of them seem to show this problem.
    I've compared dmesg/lspci on systems that have the problem and others and
    haven't found any "big" differences.
    Below is some information of the systems that shows this problem most of
    all.

    this is an LSPCI of this machine:
