The umblurred blur

Version:           unspecified (using Devel) 
OS:                Linux

Can't get the blur effect to work. I have an intel GM965 video card according to lspci below:

[edney@padme ~]$ lspci | grep -i display
00:02.1 Display controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c)

And according to glxinfo i got GL_ARB_fragment_program:

[edney@padme ~]$ glxinfo | grep GL_ARB_fragment_program
    GL_ARB_fragment_coord_conventions, GL_ARB_fragment_program, 
    GL_ARB_fragment_program_shadow, GL_ARB_fragment_shader, 

I can't get blur and because that reading the tool tips is hard.

Reproducible: Always

Steps to Reproduce:
Have the same hardware and active the effect or not, since it's enabled by default.

Actual Results:  
Transparent tooltips still transparent but no blurred background.

Expected Results:  
Blurred background.

Package versions:

[edney@padme ~]$ rpm -qa | grep kdebase

Nice!

As soon as it reach Fedora repo I'll try it out!

Thank you! That was fast!

I confirm this issue here on kubuntu with kde 4.5 beta 1, I also have an intel card, so I guess it's the same thing and will be fixed for me too in beta 2.
Comment 6 Brian Beck 2010-06-10 23:37:58 UTC
I recently installed KDE 4.5 beta 2 (4.4.85) and I don't see the blur effect even though I have a similar graphics card, and the proper glxinfo attributes.  All of the other kwin effects seem to work but this one.  I will attach my glxinfo output, perhaps the solution is there.

Distro: Kubuntu 10.04

$ lspci | grep -i display
00:02.1 Display controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 03)

$ glxinfo | grep GL_ARB_fragment_program
    GL_ARB_draw_elements_base_vertex, GL_ARB_fragment_program, 
    GL_ARB_fragment_program_shadow, GL_ARB_fragment_shader,

Hi there!

Don't know if it related to this bugfix but since i installed beta 2 i can't get desktop effects working. It's a mess now. Whenever i try to activate it, kwin crashes and effects are disabeld. I first tried it with the old configs, then i started to switch values but no effect.

Thank you.
Comment 9 Thomas Lübking 2010-06-11 03:00:40 UTC
the reason why the blurring doesn't take place is explained in the other bug, therefore i mark this as dupe.

whether the segfault is related to the patch or not cannot be said w/o a backtrace. in doubt, deactivate the blur plugin but the backtrace will help to fix a possibly related bug.
