[Bug 292214] Re: Xinerama broken since intrepid on MGA

 

I spoke a little too soon.  Things *mostly* work, but there's an
irritating bug I've hit 3 times  where the mouse cursor rapidly flashes
and the mouse locks up.  It looks as though it's confused about which
monitor it's on and some of the flashes are on the far right of my
leftmost monitor and some on the far left of my right monitor.  In
earlier release I've seen a couple other quirks where there's some
confusion about which area is part of which monitor, but this is teh
first time there's a lock up.

I've attached my /var/log/Xorg.0.log.   There're some errors in there
that might be informative if (unlike me) you actually know what you're
doing.  Here's the bit that caught my attention:

[mi] EQ overflowing. The server is probably stuck in an infinite loop.
