Comment # 8 on bug 1089366 from Gerben Jansen

Same here, have a Lenovo T530 which as running Leap 42.3 fine.

Upgraded to Leap 15 and got the same error message "failed to start setup
virtual console"
Monitor show those triangular glitches.
the login window (where i type in my password) is sluggish.

Over time I had pretty good experience with upgrading openSuSE, I think i
started at 11.3 on this Laptop and upgrades were OK until 42.3, however this
Leap 15 upgrade is below standards i think.

Question: is there a way so that i can redo the upgrade (especially the
graphics part) ?
