Description Shi Jin 2005-01-12 17:44:54 UTC
While Matlab6 works fine.
For Matlab7, no matter which WM I use, I get the same error and X crashes:
This should not happen!
        An unresolved function was called!

Fatal server error:

1. Which Linux distribution+version do you use ?
2. Which gfx gard do you use ?

It is running gentoo.

spyderous:
Does Gentoo ship with X11R6.8.2RC1 already ?
Comment 4 Roland Mainz 2005-01-12 18:52:21 UTC
Reporter:
1. Can you please attach the full Xorg.0.log file under
https://bugs.freedesktop.org/attachment.cgi?bugid=2271&action=enter
2. Can you try to use the "nv" driver instead of the "nvidia" driver, please ?
Comment 5 Donnie Berkholz 2005-01-12 18:55:23 UTC
First, a quick explanation:
Gentoo has three "levels" of packages: stable, testing, and hard-masked, the
last of which takes a little work to install.

I had 6.8.1.901 in the hard-masked state, and someone mistakenly removed it from
the mask, so it's now in testing. Yesterday, I had a talk with that someone. I
can't push it back to hard-masked at this point, so in testing it stays, to my
regret.

Summary: Yeah it's in, but it's not available by default.
Comment 6 Shi Jin 2005-01-12 21:30:33 UTC
First, nv driver doesn't help.
Second, I figured out it is the java of matlab that is causing the trouble. With
-nojvm option , matlab runs fine.
Thanks.

We need to figure out _which_ function is missing here... any clues/ideas ?
Comment 8 Adam Jackson 2005-07-03 14:48:48 UTC
starting with the 6.8.99.14 snapshot, on linux systems, the X server can print
its own backtrace when it crashes.  please confirm that these bugs are still
valid with 6.8.99.14 or later, and if they are please attach a the server log
from the crash.

I am closing this bug due to the lack of inactivity. If the problem still
persists, please reopen.
