Created attachment 51542 [details] Output of glxinfo Version: unspecified (using KDE 4.5.1) OS: Linux When open the Desktop Effects KCM to try enable the Desktop Effects, all settings are greyed out and there is an "I-icon" (info) with the following text next to it: "Desktop effects are not available on this system due to the following technical issues:" But there are no reasons given. I'm using the open-source ati drivers (see attached glxinfo.txt) Reproducible: Didn't try OS: Linux (x86_64) release 2.6.35-20-generic Compiler: cc
I'm using Kubuntu 10.10 (still beta) with the latest updates from today.
wihle this sounds like a UI bug, try to run "kwin --replace&" from a textshell (konsole) and watch the output for more information If there's still no hint and esp. iff even the xrender compositing doesn't work, check (attach) your /var/log/Xorg.0.log - could be compositing support isn't activated at all by the server
Ok, I ran your command and copied the log to the file I attached. KWin says my OpenGL library is unsafe. But besides that, I still wonder why the UI says it will show this reason in the UI without showing it.

as mentioned: the UI thing is obviously a bug. the gl compositing caused a segfault your driver in the past, try to remove the OpenGLIsUnsafe key (or set it to false) in ~/.kde/share/config/kwinrc, then try "kcmshell4 kwincompositing" - prepare for an instant crash - if not, you might have gl compositing. the xrender autofallback was removed in the last moment, therefore the debug output is wrong, you can try to activate it in the advanced tab (but some effects won't work and the performance might render it useless)

Ok, I will wait until KDE marks my driver as being safe. This bug report was only to report the UI bug. Thanks for your hints!
Maybe someone can change the report status to CONFIRMED?
This also happens on Mandriva Linux Cooker on a P4-2.4GHz (x86-32) with this card: [card] Card:ATI Radeon HD 2000 and later (radeon/fglrx): ATI Technologies Inc|RV630 PRO AGP [Radeon HD 2600 PRO AGP] [DISPLAY_VGA] [/card] Regards, -- Shlomi Fish
i have the same bug with kde 4.6 with ubuntu 10.10 the default drivers of an HD4870 cant click the button for enabling effects, and it dosnt show me a reason. was running effects fine under compiz if i can give you some info, just tell me what
I can no longer reproduce this bug, because I can enable desktop effects in KDE on my Pentium 4 machine with the ATI Radeon HD 2600 Pro card without any problems. It may still exist, though.
what did you do to make it work?
(In reply to comment #12) > what did you do to make it work? I didn't do anything except maybe set LIBGL_ALWAYS_INDIRECT=1 in my environment in .Xclients (may be a different file under non-Mandriva/Fedora distributions), and it got solved after the upgrade to KDE-4.5.x on Mandriva.

ok i found a solution via google: "I also had this problem a few weeks ago with KDE 4.5... You have to edit your kwinrc (.kde4/share/config/) . You have to change these parameter to the following values: CheckIsSafe=false DisableChecks=true OpenGLIsUnsafe=false I got this information from the KWin developer. Hope this works for you!" https://bbs.archlinux.org/viewtopic.php?id=112604 credit to Lothium
