Description J. Scott Berg 2004-06-22 08:32:03 UTC 
X server starts up OK.  Almost everything runs just fine.  I run xmgrace (grace,
a plotting package, uses the lesstif widget set).  Select Plot->Axis properties,
select the Axis label & bar tab, and the SERVER crashes (segfault), but only if
I have Option "DPMS" in the monitor section.  If I comment that option out,
there is no problem.  Adding Option "NoHAL" "True" to the Device section doesn't
help.

Linux, kernel 2.4.26, glibc-2.3.2, gcc-3.4.0.
xorg-6.7.0 built from source, here is the interesting stuff in host.def:

#define HaveMatroxHal		YES
#define DefaultGcc2i386Opt	-O2 -march='pentium4'
#define TermcapLibrary		-lncurses
#define ExpandManNames		YES
#define UsePosix		YES
#define ForceNormalLib		YES
#define CppCmd		/opt/gcc/bin/cpp
#define HasZlib		YES
#define HasLibpng	YES
#define LibpngDir	/opt/libpng
#define HasFreetype2	YES
#define Freetype2Dir	/opt/freetype
#define HasFontconfig	YES
#define FontconfigDir	/opt/fontconfig
#define HasExpat	YES
#define ExpatDir	/opt/expat

Versions of the existing libraries are ncurses-5.4, zlib-1.2.1, libpng-1.2.5,
freetype-2.1.8, fontconfig-2.2.2, expat-1.95.7.  Matrox HAL is 3.0.

lesstif uses fontconfig and freetype.

Created attachment 408 [details]
/var/log/Xorg.0.log

/var/log/Xorg.0.log for the crash.  Used Option "NoHAL" "True" in this case.
Comment 2 J. Scott Berg 2004-06-22 08:40:01 UTC 
Almost forgot: added -DHAVE_FT_BITMAP_SIZE_Y_PPEM=1 to DEFINES in
xc/lib/Xft/Imakefile, otherwise Xft won't work quite right with bitmap fonts and
freetype-2.1.8.
Comment 3 J. Scott Berg 2004-06-22 16:25:01 UTC 
It appears to be specific to the mga driver: I have another machine with the
same configuration but with a radeon driver, and there is no problem.
Comment 4 Adam Jackson 2005-07-03 14:49:40 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.
Comment 5 Adam Jackson 2005-10-21 22:39:22 UTC 
a quick look over the mga driver doesn't show anything obviously wrong with the
DPMS support.  scott, please reopen this when you have a log with a backtrace in it.
Comment 6 Timo Jyrinki 2007-02-22 14:26:17 UTC 
Marking broken (status null/blank) bugs in xorg with no activity in a long time as fixed. Please reopen if you think it's necessary, but first do a search if a similar bug report is already filed and in a NEW/ASSIGNED state. These bugs do not currently show in most search results as they do not have any status.
