How to get Lubos Lunak's KDE xinerama improvements patch?

[seldom_used]

Hi,
There is a set of patches by Lubos Lunak that adds some nice ehnancements to KDE's xinerama handling (http://ktown.kde.org/~seli/xinerama/). I used it on Suse 10.1 and loved it, and I'm trying to get it to appear in my new Gentoo install.

2.6.18-gentoo-r6 smp, KDE 3.5.5, amd64, Xorg 7.1, a clean install 2 days ago

Here's what I did
- installed a kde monolithic build (emerge kde), then discovered the patch isn't there
- after reading a blog at http://farragut.flameeyes.is-a-geek.org/articles/2007/01/28/today-in-gentoos-kde-land switched to kde split ebuilds since the patch is there:

I've tried the latest KDE build as well to make sure there wasn't another component needed to complete the patchset:

After several more attempts I still can't get the new functionality to show up in the kde control center...
It seems the patches are only in the 3.5.5 masked sources, not in 3.5.6. Am I correct?
Anyway I've tried to unmerge all kde-related packages, remove any files it may have left behind, and emerge the latest 3.5.5 split ebuild again.
I did something like

Looking for these patches myself and after some research it seems that all the patches applies when building as I get:

kwin:
* Applying kwin-3.5.5-seli-xinerama.patch.bz2

kdesktop:
* Applying kdesktop-3.5.5-seli-xinerama.patch

kdelibs:
* Applying kdelibs-3.5.5-seli-xinerama.patch.bz2

qt:
* Applying qt-3.3.8-seli-xinerama.patch


But I still don't get the functionality of the patches when all is built and done...

Yeah, I see the patches during emerge, too. I have kind of given up to get it working. The features are great though, especially keybindings to send windows to different screens, and limiting alt-tab to show only windows from the active screen.

Now that I think of it the alt-tab only shows windows from the active screen is working here, though I don't know how to turn it off or on.....

I have found that the patches are indeed applied. However, the elements that control them are hidden.

The "Separate screen focus" and "Active mouse screen" options can be found in kcontrol under Desktop->Window Behaviour. The Separate Screen Focus seems to be inverted (i.e. enabled when the check box is cleared and vice versa).

The keyboard shortcuts to move windows between screens and switch screen focus have to be added manually to the kdeglobals config file in ~/.kde/share/config
On my box KDE is constantly updating this file, so I had to logout and do the editing on the console. What you need to do is this:

-Open the file ~/.kde/share/config/kdeglobals in a text editor.
-Find the section labeled [Global Shortcuts] (I just searched for a known existing shortcut, e.g. "Switch to Next Desktop".
-Add the new shortcut definitions in the same format as the existing ones.

The shortcut names are (taken from the kdebase.patch from http://ktown.kde.org/~seli/xinerama/):

Window to Screen 0
Window to Screen 1
Window to Screen 2
Window to Screen 3
Window to Screen 4
Window to Screen 5
Window to Screen 6
Window to Screen 7
Window to Next Screen
Switch to Screen 0
Switch to Screen 1
Switch to Screen 2
Switch to Screen 3
Switch to Screen 4
Switch to Screen 5
Switch to Screen 6
Switch to Screen 7
Switch to Next Screen

For example, I added these lines:

Switch to Next Screen=Win+Q
Window to Next Screen=Win+Ctrl+Q


Start up KDE, and the shortcuts should work.


Hope this helps

Yes, it worked for me, thanks very much! I remember editing the file a while back, but I probably did it while KDE was running so the changes never persisted. It works fine now.
