Window Decoration native KDE 3.2 +

Crystal-GL is the next generation of my crystal window decoration theme.
By using OpenGL to render itself, it simulates refraction and light mapping! Check out screenshots! NOW!

I name the deco HIGHLY EXPERIMENTAL! Don't blame me, if it brakes your computer into two, if it crashes kde or makes it unusable. THIS IS BETA, NO WARRANTY.
If it breakes kwin, even on startup, remove your ~/.kde/share/config/kwinrc file, to reset the kwin settings to default.

WARNING: You need to have write access to the 3D acceleration device, if exists. I.e.: /dev/dri/* or /dev/nv*. Otherwise the deco or kcontrol may crash.

It looks very similar to crystal, but has more eye-candy and smooth animations.

* Grabs your wallpaper and simulates bended glass, little lighting. You are able to specify the ior. ;)
* Support for button themes. Feel free to swamp me with cool themes. :D The themes are the same than the ones in crystal.
Knifty button theme by Enso

* Needs a working GL subsystem!!! Don't blame me, if yours is broken!
* Be careful on nvidia systems, if under load, the gl subsystem may become *real* slow, so my deco.
* Needs KDE >=3.2 and QT>=3.2 to compile.
* May be slower than any other deco
* May be fat
* May make you drool, and you might forget to eat, sleep or even breath!

-- INSTALL -------------------------
Basic Installation (from the console):
- Step 1
$ ./configure
OR: $ ./configure --prefix=`kde-config --prefix`
- Step 2
$ make
- Step 3 (as root)
# make install

If configure fails, check that you have both the Qt and KDE development headers installed. If you used a previous version before, you need to restart kde to use the upgraded version.

Please give some feedback or tell me some improvement suggestions.
I would be very happy about some packages, like for Mandrake, Debian, Suse, Redhat, etc! PLEASE DON'T POST PACKAGES AS NEW CONTENT, just notify me and mail it to me, and I'll host them.

PROVIDED PACKAGES MAY NOT BE UP2DATE! Check out versions number!

Thanks to bitwit for each others help with the GL-deco stuff!

Enjoy! :)

* All packages up to date now

* Made look antialiased caption damn good. Enabling this is RECOMMENDED now!
* Fixed menu button image bug
* Split up rendering process into four for each border. Maybe speed up or (most likely) speed down. :-/ Should fix nvidia-slowdown-bug on maximized windows.
* Added feature: "Scroll" through windows, by using the mouse wheel on the title bar, as well as an option in the configuration dialog to disable this immediately :>
* Improved config dialog a little

* Added extreme slick "handpainted" button theme (thank you, Marco)
* Fixed some bugs, which almost drove me crazy on my notebook.
* Little speed up in the initialization
* Improved my "button-rendering-engine" a lot. Now button tinting uses GL, too.
* Added more options for button tinting.
* Added option to make the hover effect fade
* Added option to disable the transparency feature completely (don't dare!)
* Added information of direct rendering and glx version to the control center preview
* Got rid of some unneccessary code, probably put in a lot of more unneccessary code.
* Added a benchmark feature for my internal use (ctrl+alt+shift+RightButton on the title bar)

* Added Knifty button theme (thanks to Enso)
* Fixed buttons
* Little code rearrangement, nothing visible

Mine too. The KDE Control Center just segfaults as soon as you select the deco. It compiled ok, though.

 Fix for nvidia sys

 by slightcrazed on: Oct 9 2005
Score 50%

For those of you running on Nvidia systems, your user needs to be part of the 'video' group in order for this to work correctly. All of the Nvidia device files (/dev/nvidia*) are permissioned to root and the group called video. This window decoration apparently needs access to these device files. I was getting the same error that everyone else is complaining about, Kcontrol crashes immediately with a segfault when trying to select this window deco. Just do this as root:

usermod -G video 'yourusername'

and you should be fine. A restart (of KDE at least) may be necessary, I can't remember.

I once beat Drizzt Do'Urden at thumb wrestling.

Didn't work at all... Kontrol Center still just crashes. My user is member of the video group, nv* files in /dev are permissioned as follows:

crw-rw-rw- 1 root video 195, 0 2005-11-06 22:16 nvidia0
crw-rw-rw- 1 root video 195, 255 2005-11-06 22:16 nvidiactl

how about making crystal-gl draw from composite instead of a bitmap?

that should be great!

Some drivers *shrug*ATI*shrug* don't support composite yet, so I'm still fine with bitmaps.

Since KDE 3.5 every window decoration will be able to use COMPOSITE, I mean, every deco can be translucent, not only crystal. Check it out, no need for special code.

well, that's kinda brute force to enable kompmgr, it's better to implement the level of compositing in the deco, so you can do deco-independent stuff, like transforms on it, and perhaps gradient transparency and stuff, and non-transparent buttons, you get the picture.

But back to my original question, couldn't you add composite support, like have both, use composite if available. would be great! composite is soon non-experimental in xorg, and then ati will make support.

No way for Decos in KDE<3.5 to make individual use of composite. This will be a KDE 3.5 feature only (if it is even possible), and I will look into thism, when 3.5 is released.
And ATI has linux support?? Can't believe it. o_O But they should improve their 3D drivers first...

very very nice, better than 'plain' crystal version. Looks wonderful on my Suse with direct rendering enabled, it is not slow.

In my humble opinion, however, the black border (on left and right) are too bold, too wide..

OK i had CrystalGL on my Old kubuntu 5.4. But now after I installed CRYSTALGL from deb file, and when i turn to window deco menu, and when i set CrystalGL, there is nothing in that window- it doesen't work. I am pretty sure I installed qt cause my PSI works. I have Nvidia drivers, and i added myself into a video group. I only dont know what with OpenGL. In fact i am linux newbie. Help if you can.

How do you like Plasma 5?
 The best KDE Desktop ever.
 Definitely a nice improvement.
 Not decided yet. Haven't tried it yet.
 I do not like some of the changes.
 KDE is taking the wrong way.
 I am still sticking with KDE 3.5.
 I have no opinion, but wanted to vote anyway.
