Lot of people got nouveau working (for some values of working) for such basic tasks. The driver is far from complete though. My suggestion is to report a bug and see what it can be done. Disabling modeset basically disables nouveau entirely and vesa drivers are used, which isn't a good idea for KDE since it enables lots of fancy stuff that requires some 3D. You could try to combine xf86-video-modesetting and llvmpipe (swrast) drivers and see if it works for you. -- Note: My last name is not Krejzi. -- http://linuxfromscratch.org/mailman/listinfo/blfs-dev FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
