Mouse cursor disappears after using xrandr

Binary package hint: xorg

I use xrandr to activate my external monitor or set the screen size of my Asus Eee 900A PC. However, since the upgrade to Ubuntu Karmic, the mouse cursor disappears after using xrandr. I'm using xorg version 1:7.4+3ubuntu10 and Ubuntu 9.10.

The commands I use are:
xrandr --output LVDS --mode 800x600
xrandr --output LVDS --off --output VGA --mode 1280x1024

After using these commands, the mouse cursor disappears, but I can still focus and click. Moving the (suspected, but invisible) mouse cursor over a desktop item, highlits it and I can activate it by clicking.

One temporarily solution I've found is to switch to the console (CTRL + ALT + F1) and back (CTRL + ALT + F7). This makes the mouse cursor reappear. Using xrandr to reset to the original settings doesn't bring the cursor back.
