I've just installed Ubunto and LMCE, but when I reboot the resolution is too high for my screens, I've tried a screen that supports 1280x1024 resolution, but no luck with thatone either. Is there any way of lowering the startup-resolution?
If your getting out of range errors from your display I would suggest using lmce Web Admin to set the resolution/refresh to one that your screens can handle;
At Web Admin go to Wizards -> Devices -> Media Directors and select the 'Resolution & Refresh' button for the MD you want to set the resolution for. Now set the resolution/refresh to one you know your display is happy with and click ok, and then confirm this on the subsequent web admin screen once you have a good picture. If you have never run the AVwizard on this MD before you should now run that and set the same resolution/refresh again and step through the wizard to the end - otherwise everytim you restart your MD your resolution may get reset.
Hope this helps.
