sounds actually like a bug in the server, triggered by the nv driver. I guess it's fixed by the following commit upstream: ,---- | commit 1e6fd65d0b95260253828678131885a4ec21c594 | Author: Michael Vogt <m...@ubuntu.com> | Date: Mon Jan 25 18:41:20 2010 +0100 | | xfree86/modes: only call gamma_set if its non NULL | | I ran accross a crash with xf86-video-nv-2.1.15 [1] and xserver | 1.7.3.901.
