Version: 2.0 (using 4.2.2 (KDE 4.2.2), Kubuntu packages) Compiler: cc OS: Linux (i686) release 2.6.28-11-generic I couldn't have more than four keyboard layouts - seems like built-in limitation. In KDE 3.5 I hadn't such problem - I could use all six laouts which I need.
In KDE4 kxkb switching groups (as it should have done) but xkb protocol currently allow only 4 groups. There's a bug in freedesktop which you can track. http://bugs.freedesktop.org/show_bug.cgi?id=19501
Is it really not possible that this is going to be fixed somehow, regardless of the protocol? Maybe by adding an option to the kxkb command line and print a warning to stdout that it's behaviour won't comply to the standard? I'm going to revert to 3.5.10 now because I need at least 6 different layouts and I won't recommend linux anymore until this is possible.
I think it's theoretically possible to have a workaround in kxkb to switch more than 4 groups, but it's quite a bit of work... I'll think about it, though unfortunately I don't have quite a lot of free time to devote to kxkb now, so no promises.
Judging on the situation in the upstream bugzilla (freedesk), seems the workaround is the only option in short run. Hopefully Andriy will find some time to concoct one.
