Description Mauro V. 2010-02-17 22:19:49 UTC 
Version:            (using KDE 4.4.0)
OS:                FreeBSD
Installed from:    FreeBSD Ports

On FreeBSD 8 and ATI Radeon X300 (RV370), whenever I login I have to manually go to settings and enable 3D effects.

Everything works ok, the problems arrives if I logout or if I turn the PC off.

Whenever I login again the 3D effects are always off, and I have to manually turn it on on every login.

I had kde 4.3.0 and kde 4.3.5 and everything worked ok, only after upgrading to 4.4.0 this started occurring.

Best Regards

For me this happens after upgrading to KDE-4.5. Each time I log in, effects are disabled (suspended really) and I have to go to System Settings to resume them.

If I restart Kwin from the console I get this message:

OpenGL compositing self-check failed, disabling compositing.

And indeed, if I go to System Settings and check the "Disable functionality checks" box, then I can log in with effects working.

I have an Intel G45 based desktop:
Mesa DRI Intel(R) G45/G43 GEM 20100328 2010Q1 x86/MMX/SSE2
2.1 Mesa 7.8.2
Detected driver "intel" , version "20100328"

Running updated Archlinux, with kernel 2.6.35.1.

Same issue for me.
Since I use KDE SC4.5.x, I have to go to the control panel in order to "Resume Kwin Effects".
And so the behaviour is each time the same :
1. Kwin notify me that it is unable to resume desktop effects.
2. After a second try, a black screen appears and so the effects are resumed.

I have to repeat this each time I'm logging in to KDE SC4.5.x

For convenience you can go to system settings > Desktop effects > Advanced and check the box where it says "disable functionality checks".
Comment 4 Thomas Lübking 2010-10-10 21:37:59 UTC 
this should hopefully go away with mesa >= 7.9rc2
Comment 5 Alberto Gonzalez 2010-10-11 13:41:56 UTC 
Yes, I have upgraded to mesa 7.9 and the problem is fixed.

Thanks.
