Bug 555915

Cursor disappears, when rotating screen 180 degrees from previous position. Examples:

These command combinations will make cursor disappear (first command can be omitted if screen is already in the needed state):
1)
xrandr --output LVDS --rotate normal --pos 0x0 --output VGA --off
xrandr --output LVDS --rotate inverted --output VGA --off

2)
xrandr --output LVDS --rotate right --output VGA --off
xrandr --output LVDS --rotate left --output VGA --off

BUT if you rotate by 90 degrees, cursor remains on the screen (works as intended):
xrandr --output LVDS --rotate normal --pos 0x0 --output VGA --off
xrandr --output LVDS --rotate right --output VGA --off
xrandr --output LVDS --rotate inverted --output VGA --off
OR
xrandr --output LVDS --rotate right --output VGA --off
xrandr --output LVDS --rotate normal --pos 0x0 --output VGA --off
xrandr --output LVDS --rotate left --output VGA --off

Same bug can be provoked by attaching external monitor, which is rotated (it is useful, when your external monitor has a pivoting stand and you use in in pivoted state).

This combination will make cursor disappear:

xrandr --output LVDS --mode 1280x800 --rotate normal --pos 0x0 --output VGA --off
xrandr --output LVDS --mode 1280x800 --rotate normal --pos 0x1600 --output VGA --mode 1600x1200 --rotate left --pos 0x0

BUT if you set external monitor at first to 'normal' state and only then to rotated state, cursors stays on the screen (as inteded):

xrandr --output LVDS --mode 1280x800 --rotate normal --pos 0x0 --output VGA --off
xrandr --output LVDS --mode 1280x800 --rotate normal --pos 0x1200 --output VGA --mode 1600x1200 --rotate normal --pos 0x0
xrandr --output LVDS --mode 1280x800 --rotate normal --pos 0x1600 --output VGA --mode 1600x1200 --rotate left --pos 0x0

X.Org packages are from default openSUSE 11.2 OSS repository.

If cursor disappeared you can make it appear by switching to some virtual terminal and then back (for example: Alt+Ctrl+F1, then back to Alt+Ctrl+F7).

This trick works fine with external monitor, but is very cumbersome if tablet PC is in slate mode (keyboard is hidden).
