From Konsole booted on old kernel and running inxi -GSaz, please paste input/output there collected. After attempt to boot new kernel, immediately boot old kernel into multi-user mode to login and capture Xorg.0.log to paste here as attachment. Xorg.0.log may be in /var/log/ or ~/.local/share/xorg/. If you find both, attach whichever has most recent timestamp. Booting to multi-user is most simply accomplished by striking E key at Grub boot menu and appending a space and a 3 to the end of the line that begins with linu, which usually wraps at least one line.

What if you run "X -retro :0" as root on Linux console after booting with the runlevel 3? Does it appear?

It went to the same state as on the end of "Boot video with loglevel=7" https://bugzilla.suse.com/attachment.cgi?id=874762

And you didn't get any kernel crash log or such? Can you login remotely while happening the blank screen? -- You are receiving this mail because: You are on the CC list for the bug.
