I went through the upgrade process from Leap 42.1 to 42.2 and when I boot up now, I just get the CLI interface and no graphical interface.
I disabled all no oS repos prior to doing a zypper dup, the upgrade seemed to go well until I rebooted. After the oS boot splash screen I get two error messages:
nouveau 0000:01:00.0: gr: failed to load fecs_inst
and
nouveau 0000:01:00.0: DRM: Pointer to flat panel table invalid
No idea what either of those mean, so any help would be welcome! If it helps, I was previously running 42.1 with proprietary Nvidia drivers and disabled that repo prior to upgrading.
I would recommend to add the nvidia repo (for 42.2) and install the proprietary driver again.
This should do in text mode (provided you have an internet connection):
sudo zypper ar -f http://download.nvidia.com/opensuse/leap/42.2 nvidia
sudo zypper inr
Alternatively, you should be able to get to a graphical system by adding “nomodeset” to the boot options (which will disable nouveau and use a generic driver instead).
