As such, a dummy 1024x768 fb is created. During KDE initialisation it does a probe of outputs and changes the screen size to 1280x1024, but it does not adjust its splash screen. The fbcon is also still restricted to using 1024x768. So you have two bugs. The first is the tempermental DVI detection, which may be hardware or the kernel. The second is called KDE. -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
