Qt GUI in linux on ati-drivers

[mnk]

To make sure this doesn't get lost in forum move.

The problem I reported on the old board still persists in rev.466.

Linux+Qt4+ati-drivers=segfault with backtrace:

#0 0xb64a6320 in ?? () from /usr/lib/dri/fglrx_dri.so

#1 0x00000008 in ?? ()

#2 0x0891e038 in ?? ()

#6 0x44ffe000 in ?? ()

#7 0x000001f8 in ?? ()

#8 0x00000000 in ?? ()

 

And BTW, is find . -name entries -exec sed -i -e 's :s vn.bountysource.com:vbam.svn.sourceforge.net/svnroot:' '{}' \; enough to make a clean move from bountysource to sourceforge ?

Could we get some more information from you (and others), if possible?

What card are you using?

Can you (or anyone else) test this with ati hardware? (Testing on either the same card or others would be welcome)

 

This way we can see if it's a driver bug or a problem with your hardware setup. Since it works on nVidia and Intel cards just fine I'd wager that it's not a VBA-M bug.

 

Oh, and I think that the backtrace would be more helpful if you installed the debugging symbols for your openGL driver.

Well, lets do it slowly:

1. I do believe that the bug comes from ati drivers

1. card is radeon 9600

1. lately I'm using ati-drivers 8.471.3, but it's shipped with fglrx_dri.so stripped...

1. however, when I checked one of previous releases (not sure which one), it had that file unstripped

and with that file I got following backtrace:

but if it's really a driver bug, I don't know if much can be done.

With xf86-video-ati, instead of ati-drivers, it doesn't crash, but has issues with OpenGL while Composite extension is enabled (emu screen covers open menus).
