--- Comment #8 from Eric <knoppix1337 at yahoo.com> ---
Tested with current openchrome as of this date
Current setup: Wyse Vx0LE 
lspci shows: [S3 Unichrome Pro] (rev 01), 
Dual HP LP2065 4:3 monitors, one DVI mode, one VGA mode (DVI/VGA "Y" adapter)
1600x1200 60hz. 
Kernel 3.2.0-101-generic

Previously when you ONLY had the VGA connected, it would boot fine with mouse
cursor present.

When testing with the recent openchrome, the mouse cursor is not present when
booted with ONLY the VGA connected.

ARandR shows a NEW Output LVDS-1 as active. If you fool around till you can
uncheck "Outputs> LVDS-1> Active" and Apply, you get the mouse back. 

LVDS-1 only haS 1 resoulution, 1600x1200. 

This board has some un-populated connector pads on it. I don't know if it is a
false detection or if the board has some un-used hardware on it.

When booted with BOTH VGA and DVI connected, it behaves as it did with previous
versions as originally described, except that the LVDS-1 now shows up, but NOT
"active"
