My mouse keeps getting stuck on DISPLAY=:0.1.


Three monitors on two cards with two X Screens.

  • Radeon HD 6950 (00)
    • DISPLAY=:0.0
    • Monitor 1 over HDMI
    • Monitor 2 over DVI
  • Radeon HD 6950 (01)
    • DISPLAY=:0.1
    • Monitor 3 (named 7 by aticonfig) over DVI
  • xorg.conf

enter image description here


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.

How stuck? Like STUCK? Or sticky edges stuck? – Kyle Macey Mar 12 '13 at 16:39
Not sticky edges. I've been diagnosing/troubleshooting for weeks now. The cursor becomes trapped inside of :0.1. When the cursor is brought to the edge of the screen (to return to :0.0), it completely resets to the other side. It's like playing Super Mario Brothers 3 on one of those levels where you can go through either horizontal side and return to the other side, except it's only one directional: it always appears back on the left side in the same exact vertical/horizontal position. I have to reset X (logout/login) to reset my cursor to :0.0. – earthmeLon Mar 12 '13 at 16:44
