Description Anders Nordby 2007-10-15 20:57:20 UTC

According to Eric Anholt, this is due to Mesa/GL problems?

Every now and then, Xorg dies (typically while running xscreensaver):

Oct 15 17:39:40 noname kernel: pid 82286 (Xorg), uid 0: exited on signal 6 (core dumped)

Backtrace:

The problem typically occurs after running xscreensaver for a while. To reproduce:

1) Install FreeBSD 6.2-STABLE that I have (RELENG_6_2 as of october 9).

2) Install Xorg 7.3 from ports. I have xorg-server-1.4_1,1 (which uses MesaLib 7.0.1) and xorg-drivers 7.3.

3) Install and run xscreensaver.

4) Wait..

Comment 1 Niclas Zeising 2013-02-22 12:52:17 UTC

This bug can probably be closed, since FreeBSD 6.4 is obsoleted, and xorg is updated to xserver 1.7.7 and Mesa/GL 7.6.1

                                         ^^^^^^^^^^^
That should read FreeBSD 6.2 of course.
