Slamd64 with linux 22.214.171.124 on AMD64
X server crashes during normal work randomly (sometimes without backtrace in
logs). Sometimes I can work for couple of hours without a crash, but sometimes X
crashes very often (more than 2 times per 5 minutes). I realized that it crashes
more often when I want to select group of icons with mouse (creating a
rectagonal selection - or whatever it is called :P)
I don't think it is related to hardware or some drivers cause I got the same
with linux-2.4.32 kernel, and other drivers(vesa, fbdev, currently radeon).

Sorry for my english and any mistakes, that's my first bugreport :P
Please post your xorg.conf and your xorg.log after the crash.

Xorg.log - crash log
Also I realized that when I am in 4th runlevel (in other distros it is 5), X
server crashes and restarts (because of kdm). But when I run X server in 3rd
runlevel it hangs whole computer(I must reset comp manually or with Magic SysRq)
without backtrace in Xorg.log (there is only first line: "Backtrace:" and
There's a trick around it: Log in remotely via SSH and attach gdb to the X
process to get the backtrace.
Does it also happen if you don't override the amount of video RAM using the
VideoRam directive? The drivers usually know exactly how much they can use.
Yes, it also crashes if I don't override VideoRAM.
I tested it on other graphics(S3 Virge PCI) and got the same.
Maybe some hardware information will be useful:
MSI K8N Neo3-F (with the newest BIOS)
AMD Sempron 64bit(s.754)
2x512MB RAM OEM
ABIT Radeon X600Pro HDTV 256MB
WiFi Dlink DWL-510
Maxtor 60GB PATA
DVD-RW LG GSA-4167
I don't know if it's related but sometimes when doing this selection, some parts
of that dotted rectagon stays on desktop, and if I want to get rid of it I have
to refresh desktop.

Sorry for the delay, but I don't have two PC's to get backtrace using ssh (but
I managed using multi-seat configuration. It doesn't work - at all - on R6.9
version, but it works - with some hangs, crashes etc - on R7.1)
I compiled R7.1 from sources, and found that it crashes too. So I compiled it
again with -g -O0 flags, applied multiseat configuration and got full
I don't know what do miWideDash/miWideDashSegment/miFillPolyHelper functions
do, so please send me link to a doc or small description and maybe I'll be able
to find the bug and write a patch.
I've forgotten to write that it must be 64-bit arch related bug because I have
no crashes when using slackware.
Sorry about the phenomenal bug spam, guys. Adding xorg-team@ to the QA contact so bugs don't get lost in future.
Sorry for the slow feedback here. This bug is really old, so I'm going to
close it. If you are still experiencing a problem, please reopen with a newer
backtrace, and I will take a look.
