strange xcb bug

I’ve recently updated my all system and with that, ati fglrx driver has been also updated (from 8.49v to 8.51v).
The driver seems to working fine, because the screen is much faster than running it without any driver.
Now the problem is with running some 3d programs as well as compiz or any glx, fglrx command such as “fglrxinfo”. I get this error:

xcb_io.c:352: _XReply: Assertion `!dpy->xcb->reply_data’ failed.
Aborted

I have tried reinstalling the ati driver and the xorg, nothing helped.
I’m running opensuse 11.0 with KDE 4.1
Someone can help me?

Hi there,

i got the same bug on my system running opensuse 11.0 and kde 3.5. There bug appeared when i updated fglrx from 8.49 to 8.51. Even openoffice seems to be ‘infected’ and doesn’t start. Does anyone got an idea how to fix this?

Seems to be pretty common:

There were listed several workarounds. You might try them.

And a more “official” bug report, with a better fix.

Well never mind i have fixed the problem, now everithing is fine. and what i did:
Downloaded the latest driver from Advanced Micro Devices Inc. (wich is also 8.51), installed it automatically (do not forget to delete the already installed driver first!!). Then i run the command from terminal as su(no need going to init 3!):

aticonfig --initial

and then:

sax2 -r -m 0=fglrx

restart your computer and everything should be fine.

My log when i run fglrxinfo:

albert@Tahvok:~> fglrxinfo
display: :0.0  screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: Radeon X1300 / X1550 Series
OpenGL version string: 2.1.7769 Release

The 3D is also working.
