if anyone needs xinerama working under kde u will need to recompile kdelibs , qt , kdebase to get xinerama build into KDE. :) to have the windows max correctly . etc .

[retsaw]

I think that's because you are using Gentoo and you didn't select the options you need for it the first time around. I should hope that wouldn't be neccessary on any binary based distro.

[crow2icedearth]

of coarse i didnt compile it in right off. because i just got more monitors. lol

and of coarse if u have binarys of kde u dont need to compile it in. im talking about LFS , and gentoo or if u want to build kde from source .

[retsaw]

Yes, but I wanted to make it clear so people who are using binary distros don't think they need to do that. :)
