See: https://bugs.kde.org/show_bug.cgi?id=101154 I tested the patch given in https://bugs.kde.org/show_bug.cgi?id=101154#c7 and made a gentoo equivalent patch and ebuild in my PORTDIR_OVERLAY directory. add the following line in src_unpack() before the make -f admin... statement: epatch "${FILESDIR}/kdebase-3.4.2-kinfocenter-opengl-fix.patch" Using this ebuild I made I re-installed kdebase and now selecting opengl works in the kinfocenter.
Created attachment 66994 [details] patch for kdebase-3.4.2.tar.bz2 to fix opengl dialog crash in kinfocenter: kdebase-3.4.2-kinfocenter-opengl-fix.patch patch for kdebase-3.4.2.tar.bz2 to fix opengl dialog crash in kinfocenter
This should be fixed now, sorry for the delay.
