    Default screen does not wake up from suspend or hibernate

    Hi,
    I have been trying to figure this out from existing posts but can't seem to get any traction.
    I am running OpenSUSE 11.4 with Gnome 3.0. and an nVidia Card. My machine seems to go into suspend and hibernation fine. I hit my start button to wake it up and it seems to come back successfully except I don't have video. Any help is greatly appreciated.
    thanks!
    Peter

    is this a super computer that fills an entire floor, or maybe a laptop?

    if the latter, does it have an Fn key combo to turn off the display? if
    so, what happens if you try to switch the display on? or maybe, try the
    Fn+screen_brighter

    or ??

    if not a portable, and no Fn key, is your monitor going to sleep
    also...can you press the power button on it, and see what happens..

    Hi DenerD,
    Thank you for your help!
    I don't have a super computer, just a laptop.
    It is a Toshiba Tecra A9 with an nVida Quadro NVS 130m video card. I am running the Quadro NVS 130M/PCI/SSE2 Driver also.
    I actually just got both hibernate and suspend to come back on but only when I have a monitor attached. If I detach the monitor and boot with just the integrated laptop screen I get the same blank screen.
    Perhaps it is looking for that monitor and does not fully restore because it is looking for this attached second screen but not finding it.
    When I look in the nVidia application it shows that I have the integrated Toshiba LCD screen. But when I look in the Gome 3.0 display module it says Unknown. I am not sure how to edit these settings but think that I may be able to solve this if I can get this correct.

    I don't have this hardware, or the definitive answer, so can only offer pointers

    1. Try googling 'nvidia resume solved how to' and similar. It will take some solid searching and reading, but you may stumble on a solution that works for your hardware.

    2. This thread may offer some clues. In particular, I have seen references to using nvidia-xconfig (as root) to generate a working /etc/X11/xorg.conf file, then adding Option "NvAGP" "1" to the Device section. Another thread on the same topic (ref post #7).

    Maybe others familiar with this hardware can offer better solutions...

    Thank you Deano, I will report back with the solution. I am a lot closer to solving this than I was when I first posted. I think it is the monitor set up I have. I believe that when I originally changed to OpenSUSE awhile back I had the monitor plugged in. So I think it is looking for the other monitor.
    Best,
    Peter

    It may well be, but only if you created xorg.conf after installing the proprietary driver, either with nvdia-xconfig or nvidia-settings (as root) AFAIU. Otherwise, any attached monitor should be detected automatically by X at startup.

    Try generating a basic xorg.conf with nvidia-xconfig as root or try the following

    Code:
    sudo sudo touch /etc/X11/xorg.conf
    sudo nvidia-settings
    Make any display config changes as required, then select 'Save to X Configuration'. See how that goes.
