Package: xbase-clients
Version: 4.3.0.dfsg.1-8
Severity: minor
I have a dual-head setup. Screen 0 is driven by a NVidia card, with
the NVidia proprietary driver, and screen 1 is a Matrox G200 with the
normal mga driver.
When running glxinfo, it segfaults when it tries to print the visual
table for screen 1.

valgrind also gives a lot of warnings in the beginning about
uninitialized bytes given to ioctl and conditional jumps, is that normal?
I haven't tried with the open source nv driver, will do when I have time.
