A known problem of the ATi driver *** This bug has been marked as a duplicate of bug 173556 *** The link mentioned above (http://ati.cchtml.com/show_bug.cgi?id=1713) is dead. I cannot find any information at the ati/amd site that this is a bug in the driver. More than a year has passed since this has been reported. With the most recent version of the fglrx driver (11.3/8.831.2-1), the invert effect still cannot be enabled. OpenGL vendor string: ATI Technologies Inc. OpenGL renderer string: ATI Radeon HD 4300/4500 Series OpenGL version string: 1.4 (3.3.10600 Compatibility Profile Context) Driver: Catalyst Driver version: 1.4 GPU class: R700 OpenGL version: 1.4 X server version: 1.9.3 Linux kernel version: 2.6.37 Direct rendering: no Requires strict binding: yes GLSL shaders: no Texture NPOT support: yes kwin(15455) KWin::EffectsHandlerImpl::loadEffect: EffectsHandler::loadEffect : Effect "kwin4_effect_invert" is not supported Can anyone familiar with the reasons for this problem point me to some information about it? I can't believe it's so hard for the ati/amd guys to fix this. just read through the dupe or gg:fglrx glsl and click through the results - much fun reading. you should be able to enforce direct rendering by exporting KWIN_DIRECT_GL=1 general help for dri: https://wiki.archlinux.org/index.php/ATI_Catalyst#Direct_Rendering_Doesn.27t_Work but notice that arch has actually dropped catalyst for its lousy quality ;-P http://www.archlinux.org/news/ati-catalyst-support-dropped/ use the Xorg driver if it works for you. seriously. > you should be able to enforce direct rendering by exporting
> KWIN_DIRECT_GL=1
that works, but trust me it is so slow that you don't want to use it.
(In reply to comment #3) > use the Xorg driver if it works for you. seriously. I just did that – invert works, track mouse works, zooming works. Thank you very much for that hint! with fglrx and KWIN_DIRECT_GL=1 kwin --replace I can also make these effects work. Direct rendering with fglrx is slow indeed. I guess I'll be using the radeon driver now hoping that one day its 3D features will mature over time as to support glossy shading in my favourite molecular modeling application UCSF chimera. |
