I have installed paldo stable 1.20 on my medion 9467.

It's an old pIII 850 MHz laptop.
When I do a logout as user, I get a black screen and the laptop freezes. A shutdown works without any problems (ok, in grub I have to add: acpi=force).

This problem does not occur with my Desktop PC (Athlon XP, via KT 400), this
shows lspci:

I could resolve the problem by replacing "vesa" by "savage" in the xorg.conf.
