Description Bryce Harrington 2011-05-05 20:08:00 UTC 
Starting after updating to linux 2.6.38, -radeon 6.14.0 and the xserver 1.10 pre-beta snapshot several months ago I've found that on my dual head display, the mouse pointer disappears when it is moved near the left edge of the right monitor.

The same behavior does not happen on the left monitor, on any edge.

I've been keeping an eye out for anyone else reporting this problem but so far haven't run across any similar reports.  I wonder if this is something you've seen?

How near to the edge 2-3 pixels? 5 pixels? 20 pixels?  If it's just a few pixels, I suspect the randr code in the xserver is just hiding the cursor on the right display as soon as the cursor hotspot crosses over to the left monitor since the hotspot is usually on the far left of the cursor.

Looks like 5 pixels.

(Just enough to make selecting text in an xterm a bit of an annoyance).

Is there a way to tune this?
