Hi, I encountered this when I distro-synced my f21 non-product to rawhide and kernel updated to 4.0 in this morning. Now no matter which kernel the system runs under, all couldn't start X, with these in Xorg.0.log: Loading /usr/lib64/xorg/modules/libvbe.so [ 99.976] (EE) Failed to load /usr/lib64/xorg/modules/libvbe.so: /usr/lib64/xorg/modules/libvbe.so: undefined symbol: xf86int10Addr [ 99.976] (II) UnloadModule: "vbe" [ 99.976] (II) Unloading vbe [ 99.976] (EE) VESA: Failed to load module "vbe" (loader failed, 7) [ 99.976] (II) UnloadModule: "vesa" [ 99.976] (EE) Screen(s) found, but none have a usable configuration.
