Hi Carlos, Thanks for the hint. I've tried 8bpp and 16bpp, but it doesn't make a difference at all :( After some experimentation here, I'm wondering if it is some kind of quirk within the NT4 driver related to alignment issues within the qemu code. The server for this qemu instance is running 32-bit Debian etch with 0.9.1, and I always see a white pointer whenever I connect. Interestingly though, I temporarily mapped the NT4 partition to my local laptop which is 64-bit Debian lenny with 0.9.1, and the mouse pointer appears correctly! So it appears that this could be a 32/64-bit related issue? On another note, I have now managed to get the mouse pointer appearing correctly on the original 32-bit server by using the ReactOS video drivers here: http://www.bearwindows.boot-land.net/vbemp.htm instead of the Cirrus drivers. Thus I have a found a cure that works for me, but it looks like I am not the only person to experience this issue: http://www.debian-administration.org/users/ajt/weblog/115.
