i dont use the hardware anymore, i think it was still there but harder
to trigger

fwiw, i think i got a chance to talk to the driver author on irc and
it was a known problem that wasn't interesting to fix because the
hardware is old and rarely used, but my memory is pretty vague about
this

please do close the bug by all means or mark it as WONTFIX or
whatever, it's not useful chasing this

Bug#318989: xlibmesa-dri: glx applications segfault inside r128_dri.so

2007-01-23 Thread Brice Goglin 
Hi,

About 2 years ago, you reported a bug to the Debian BTS regarding a
segfault of the r128 DRI driver when requested a large resolution with
big depth.
Did you reproduce this problem recently? If not, I will close this bug
in the next weeks.

Thanks,
Brice

Indeed, not enough for the resolution you're running at depth 24. See
the line

(II) R128(0): Reserved 0 kb for textures at offset 0x00

So this is basically a configuration issue, but of course, one could
argue that the r128 DRI driver shouldn't segfault in that situation...

I don't have a Radeon on this machine --- it's some ancient Rage
M3/128 thing ("ATI Technologies Inc Rage Mobility M3 AGP 2x (rev 02)"
reported by lspci).

As to why it doesn't crash anymore I'm not so sure, it turns out the
xorg.conf ended up being a verbatim copy of the XF86Config-4 file,
probably as part of the upgrade I had to manually that I didn't
notice.

As to why DRI is working now, I'm using a 16-bit visual not 24 or 32.
I guess I don't have enough video memory or something?

Hello, David. Please apply the attached patch to 
xlibmesa-dri.bug.script in

So...could you please send a diff between the resulted configuration 
and your 
working configuration, to know what possible parameters are recommended for 
Radeon users? Come on! :-)

2005-07-19 Thread Chris Wedgwood 
Further information and some more fiddling about:

  * I am able to get things to crash again using the xorg.conf that
resulted from the xf86->org upgrade.  Disabling direct rendering
stops the crash.

  * The xorg.conf produced by installing xserver-xorg doesn't not
crash as direct rendering does not work.

  * If I hand-edit the xorg.conf file 'the way I like it' then direct
rendering does work again and does *NOT* crash.

So there is something that's a little bit finicky here but things do
appear to work if poked the right way.

It is xorg stuff:

[EMAIL PROTECTED]:~/Desktop$ dpkg --get-selections|grep xserver
xserver-common  install
xserver-xfree86 deinstall
xserver-xorginstall

(i didn't deinstall'ed xserver-xfree86 but didn't purge it in case i
needed to go back)

> Maybe there is a problem with the xlibmesa-dri reportbug script.

I suspect so, I didn't even think about it and just let it do it's
thing.

Thinking it might be partly because of the xf86->xorg upgrade process
I purged xserver-common xserver-xfree86 xserver-xorg and some other
cruft, moved the configuration files out the way and installed
xserver-xorg and xlibmesa-dri letting it decide the configuration.

DRI is now *not* working at all --- so I can no longer reproduce the
crash (ie. no attempt to use direct render is made so things work
albeit painfully slowly).

Attached are the files from *before* I reinstalled things above.
These show DRI was being enabled then but diff'ing between the two
configs I really have no idea why it won't work now or if these are
useful given I can't reproduce the problem on a clean(ish) install.

Excuse me, but I do not understand this. You claim to have 
6.8.2.dfsg.1-3, 
but your report has XFree86 logs and information. Maybe there is a problem 
with the xlibmesa-dri reportbug script. I will take a look this morning, but 
meanwhile, please supply /etc/X11/xorg.conf and /var/log/Xorg.0.log.
