    wake from hibernation - screen display problem

    Some times, not always when i wake from hibernation the screen will display a scrambled view, you can see the desktop, but its all over the place.

    this can be instantly fixed by turning the screen off and on again. I can't find a pattern to this, it seems to be random, maybe one in 10 resumes it will do this. quite annoying.

    does anybody know of any setting i can alter to avoid this?

    setup is:

    Mac mini running xp sp2
    carnetix CNX-P2140
    LinITX.com 7" touchscreen plugged directly into mini, no hub.

    I'm having a similar problem on initial boot. Seems to happen only when the car has been sitting a while. Sometimes I have to turn the monitor off and on multiple times before it's fixed.

    Running xp on mac mini with Xenarc touchscreen.

    I'm thining it could have to do with the order that windows is recognizing devices as it boots up? I'm not using hibernation, but your issue may not be hibernation related.

    Maybe using devcon to stop and start USB devices would help.

    yes, i thought it was to do with it sitting for a while as well. it didnt seem to happen in winter either, so i thought it could of been heat related?

    but as you say, i'm sure its more likely to be the way windows turns on the USB ports.

    because the resume screen will come up fine. then it'll go black and then when it comes back on it'll be messed up again.

    I did try once using xport to turn on and off the touchscreen, but it always caused the touch screen to not work untill it was reinstalled?!

    which is odd, as the xport works great for everything else. i looked at devcon, but it just baffled me

    I have the Carnetix P1900. I've only had it installed for a couple of weeks. It's almost like the connection is loose -- but then you'd think it would happen when driving too. I'll post back if I learn anything.

    It sounds more like the monitor didn't sync up right.

    Here's something you can try if you're already using XPort. It turns on monitor standby for 2 seconds after coming out of hibernation (and when it starts. Sorry, just a quick hack for now).

    So just replace the existing xport.exe with this one?

    Yep. That's all you need to do. There's about a 5 second delay, and then your screen goes off and back on. Tell me if it works and I'll add it to the settings.

    This worked for me! Thanks! I didn't notice a delay, but I was in a hurry ... just noticed the screen booted up corrupt, and the next time i looked I was looking at my rr menu. By 5 second delay do you mean that 5 seconds after xport loads, it sends a screen reset or (off then on)?
