Hi everyone!

I have some problems with enabling compositing effects on my gentoo linux. I've compiled plasma-workspace with compositing USE flag, enabled GLX and compositign extensions in xorg config. Also I've compiled xorg-server with VIDEO_CARD nvidia flag, and emerged dri2proto, and nothing ; When i trying to enable compositing effects in system settings -> desktop -> desktop effects hint says:

Code: Select all

Compositing is not supported on your system.
Compositing was disabled at compile time. It is likely Xorg development headers were not installed."

How can i enable this effects? Where i did mistake?

Can you run "glxgears"?

If you don't have them installed, it's in x11-apps/mesa-progs package.

Yes, i can run glxgears.

What's interesting is that it says that that they were disabled at compile time... Have you tried reemergeing KWin? Maybe portage screwed up the ordering and the headers ware installed after KWin.

Here are my flags if that helps...

Code: Select all

[ebuild   R   ] kde-base/kwin-4.2.1  USE="kdeprefix opengl xcomposite -captury -debug -xinerama" 0 kB

Ok, i've recompiled kwin again, and it works, thanks!

And one more question, how can i get additional effects in gentoo? In arch linux i had much more effects. Also my shadows looks more like a transparent border than real shadow...

I'm not sure because I haven't used seen what Arch provides, but I have about 30 effects in System Settings » Desktop Effects » All Effects. The shadow configuration should also be there.

Some additional effects like diffrient window or desktop switching, flexible windows when moving etc, so i'm wondering how can i get this extra effects?

By "flexible windows" do you mean "wobbly windows" or is it something else?

Yes, sorry, in arch i had polish kde, and i didn't remember name of it

You should definitely have those effects in there. They're a part of the KWin package:

Code: Select all

$ equery f =kwin-4.2.1 | grep wobbly
/usr/kde/4.2/share/kde4/services/kwin/wobblywindows.desktop
/usr/kde/4.2/share/kde4/services/kwin/wobblywindows_config.desktop

But i don't have it... here's my screenshot of it.. and take a look of that strange shadow, how can i fix to normal look?

Screenshoot

That's really strange... :-S

Could you post the output of

Code: Select all

emerge -pv kwin

Code: Select all

mantis marq # emerge -pv kwin

These are the packages that would be merged, in order:

Calculating dependencies... done!

Sorry, but I'm afraid I can't really help you...

You could try asking on Gentoo Forums or even on IRC (#gentoo-kde on Freenode)

Or, you could wait until 4.2.2 is added to the portage tree (I heard they are planning to do it this on Monday. Maybe after rebuilding it, it will start working correctly...
