I have a really strange X (?) problem. My physical setup is:
Dell Optiplex 990
VisionTek 210 nV DMS59 PCIe video card (with a DVI splitter)
dual Dell P2411H monitors
I’m running OpenSuSE 11.4 (x86_64 fully patched) with the current nvidia drivers and kernel module. I’m running KDE and kdm in case that matters.
I’ll be happy to provide the xorg.conf file (written automatically by nvidia-settings) if that would be helpful.
If I power off the two monitors, and then power them on again, the right monitor will come back on. The left monitor (which is the primary one… it’s the one where the login screen appears when you are first logging in) reports that it is in power save mode. Wiggling the mouse, typing, etc., do not wake it up. The only thing that wakes it up is the detach the DVI cable from the monitor and reattach it (and sometimes it takes a couple tries).
I have used two (identical) video cards and splitters, and the problem occurred with both, so the problem doesn’t appear to be with either of them. I also swapped monitors, but after the swap, the problem still occurred on the left monitor, and the old left monitor (which was now right) came on fine, so it doesn’t appear to be a monitor problem.
I’m baffled. For now, I just won’t turn off the monitors (or at least not the left monitor). Anyone have any better suggestions, or even better, a fix?
