I have some issues with my fresh ZBox
I was seeing some video tearing; the 5.1 isnt working (yet) and I have this annoying issue with the cursor showing after having switched away from the ZBox HDMI.
Apparently the 5.1 issue is solved in the newest proprietary Catalyst 11.12 driver and the installing info is at Ubuntu Oneiric Installation Guide. Reading through the text I couldn’t start changing stuff since we’re watching the box right now 🙂 The text however held a few other very interesting tips
Video Tearing : aticonfig –sync-video=on
And this seems to be solved 🙂 Or at least very much improved 
Research is necessary
ACPI : aticonfig –acpi-services=off
I’m thinking that switching away from the HDMI triggers an ACPI event, so why not try disabling it 😉 Testing is required.. though this might be a long shot Edit: Long shot taken an proven wrong. Enabling ati, Cursing at the little center screen cross. And if only ‘xte -x :0.0 “mousemove 100 100″‘ would give some temporary relief but that doesnt do it either. Or adding ‘Option “HWCursor” “False”‘ to the device in the /etc/X11/xorg.conf – back to the drawing board 🙂
And to refer to last weeks XKCD; “If you really hate someone, teach them to recognize tearing” *sigh*
Next up though; installing Catalyst 11.12 drivers!!
