KWin unstable after update from 9.04 to 9.10

[tomarctus]

Hello!
Could someone help me with my problem? I haven't found any solutions.... >_>
Also my problem:
I have upgraded my Kubuntu 9.04 to 9.10, everything was fine, but after restart (using kernel 2.6.31-14, the newest one) and the login, I see a window, that tells me that KWin is unstable, it has frozen often, and I should chose another windowing system... what I, of course don't have. ^^"
I'm now using kernel 2.6.28-16, and it works...... although I don't have any sound....
My system is completely updated, I'm using my laptop, with ATI Mobility Radeon HD 3470 video card, and the Catalyst driver (9.10).
Any help please?

I'm having the same problem with older 2.6.28.

kwin: ../../src/xcb_io.c:542: _XRead: Assertion 'dpy->xcb->reply_data != ((void *)0)' failed.

Yeah. I have the same thing, except that I have some Hungarian in it. ^^
/ "kijelentés meghiúsult" == "failed" /
It was quite hard to get this output without having keyboard input on my terminal.

tomarctus@Stray-Wolf:~$ kwin

Any ideas how I could change this? >.>

Hey I got it! Erase your Ati drivers (sudo sh /usr/share/ati/fglrx-uninstall.sh) then reinstall with sudo sh ati-driver-installer-9-10-x86.x86_64.run --buildpkg Ubuntu/karmic. Then install all deb packages and do /usr/bin/aticonfig --initial. Reboot.

Let me know.

Wooww......
I don't know how... but it's working.....
10/10.
Thanks. =D> It was a great help.

You're welcome tomarctus. It's been a pain in the *** for me too, but luckily a little tweaking has helped.

Same here on a Thinkpad T42p with ATI FireGL T2
I went trhough all betas of Karmic Koala 9.10 without major problems (except for the Wireless not working).
Graphics performance was poor, so I decided to install the fglrx - ATI drivers via the KPackageKit.

On reboot, KWin was reported to be unstable.
The KDE crash report did not accecpt the available backtrace data.
I could not remove the fglrx-packages via KPackagekit or via
Konsole-Terminal because the keyboard would not function anymore. The whole system is rendered unsuable now, because in crucial places keyboard input is not working and the title bar of al GUI windows has disappeard.

I managed to install the debug symbols for KDELibs5-dbg (did not find any for KWin), but
even then I could not get sufficient backtracing information for
the KDE crash handler.

Hi, I think this could solve my issue with Ubuntu 9.10 becuase I have issues with screen in my ATI Radeon. But I don't understand completely your third step. When you say ..."Then install all deb packages ..." Where I have to do that? Could you provide me more details.

Sorry but I am very new with Linux.

Thanks in advance!!

OK so I waited a bit to install the FGLRX driver because of issues in the past and it seems I've missed the boat. If you have an older ATI card specifically the ATI Radeon Series you MUST use a legacy driver from ATI.

From the ATI site: http://support.amd.com/us/gpudownloa...4&lang=English

The Linux ATI Catalyst™ driver will only be supported in Linux distributions prior to February 2009 for the legacy products listed above.

Any customers using a combination of a ATI Radeon™ HD 2000 Series, ATI Radeon™ HD 3000 Series, or ATI Radeon™ HD 4000 Series product with any of the legacy products listed above in a single PC system must use the ATI Catalyst 9.3 or earlier driver. All future ATI Catalyst™ releases made available past the ATI Catalyst™ 9.3 release will not include support for the legacy products listed above or any of the features associated with those legacy products.

This means that the version currently in the Karmic Repository is NG no good for folks like myself and a few of the other posters. My only inclination is to try compiling with Jaunty and seeing if it will work.
