Only OpenSuSE 11 works. Too bad that printing doesn't work in OpenSuSE 11 anymore.... My take: the X-server makes some assumptions that are not true for widescreen hardware and throws away the modelines it gets (because it thinks they won't work). Seems to have been fixed with later X releases (or patches). For desktop-use, there's little alternative to Ubuntu/OpenSuSE/Fedora and re-installing every couple of months (and living with new and surprising bugs every release). Rainer
