My mouse keeps getting stuck on DISPLAY=:0.1.
Three monitors on two cards with two X Screens.
- Radeon HD 6950 (00)
- Monitor 1 over HDMI
- Monitor 2 over DVI
- Radeon HD 6950 (01)
- Monitor 3 (named 7 by aticonfig) over DVI
Previously on 12.10/12.04, I have been able to get a similar setup working by invoking
aticonfig --init=dual-head and then
aticonfig --set-pcs-val=MCIL,DigitalHDTVDefaultUnderscan,0 (The latter makes sure my displays have no black boundaries/No Underscan).
While I am aware of bugs in Nautilus/Compiz that make a second X Screen buggy and messy, I have never had my cursor get trapped on it.
