I've been trying various flavours of Mandrake on my P1120 since Mandrake 9.
They all worked pretty well, except that I've never managed (i.e., gone through the trouble) to get the following working:
1. Touchscreen (maybe 2 people on earth managed to make this work)
2. Longrun (supposedly in the built into the latest mandrake kernel)
3. sleep on lid close.
Right now it's running 10.0 Community and everything except the above works, including USB, simultaneous USB mouse and eraser mouse, disk spin down, screen blanking, wireless. I had to manually tweak X for the screen size and mice, but everything else, including built in wireless was good to go out of the box.
When 10.1 Official comes out, I'm going to try to get 1, 2, and 3 above to work.
If anyone has any pointers, I'd love to hear them!!!
