I have an Kodi buntu install on an Acer Aspire Revo R3600 nettop that refised to display in my TV's native resolution of 1080p. I could manually change the reselution to 1920x1080, however when the Revo R3600 nettop went to sleep, it would wake up and be back to outputting at 720p. After a lot of messing about i found its pretty easy to force 1080p by editing your xorg.conf Note: If you install the XBMCbuntu Gotham release (xbmcbuntu-13.0~gotham_amd64.iso) you will not have an xorg.conf by default. You can however copy the example configuration then follow my instructions below. To copy it simply type the following: First ssh is in your XBMCbuntu or OpenELEC install, then type the following command: Now you need to add the following to your xorg.conf: Option "metamodes" "1920X1080_60 +0+0" Modes "1920x1080_60" You can see where i made the changes below: Save the changes by pressing ctrl+o Then reboot your Kodibuntu / XBMCbuntu or OpenELEC install and you should now find that your device will always output in 1080p, even after it resumes from sleep.
