Hi

Some where in the forum is a post on getting the screen resolution correct for the ubuntu desk top underneath XBMC. I have searched but can't find it. If any one has it bookmarked could you post it hear. My desktop is way out with lots of underscan.

Thanks

/var/log/Xorg.0.log is the file you need to look at. Post it to pastebin.

Disable overscan in your TV

That's Xorg.0.log

However be careful as I'm afraid there might be two issues in the log. I have just started using a Yamaha receiver RX-V573 and it occasionally changes the screen resolution of XBMC to 720. A reboot of the machine resets XBMC to 1080. This is new and has nothing to do with ubuntu desktop being under-scanned.

That's a log were it came up in 720 due to the receiver and a reboot fixed it.

Actually, I have just found AMD catalyst in XBMCubuntu and the res is set smaller than the screen size. So that's the problem. However I can't get Catalyst to start in super user mode. On installation I setup 1 user and password. Clearly I need to log in to X as root?

Never log in to X as root.

I assume you are talking about the amdcccle control program. If so run it via gksudo, as in

Code:

gksudo amdcccle
