Fresh install of http://download.opensuse.org/factory/iso/openSUSE-Factory-DVD-x86_64-Snapshot20141011-Media.iso gave me no resolution problems but only because GRUB2 appeared in text format. Checked settings in YaST and there should have been a graphic interface. Tried another machine and GRUB2 menu was also in text on that, so it's a feature of this release.
