All I need to do is get into YaST to enter in the boot options to enable my mouse (for my situation, I just need to enter in i8042.noloop and the mouse will work).
However, I’m not familiar with openSUSE keyboard navigation. What do I press to get to that point? Anybody?
Scratch that, fellas. I forgot that, upon rebooting after initial install, it shows the GRUB startup options screen, where I can enter in my own boot option parameters for that boot session.
Entered it in, went to YaST > System > Boot Loader, and appended it to my boot options. We’re all gravy now.
