Comment # 13 on bug 1119621 from sep hoogzaad

I have (had) the same problem. Kernel 4.19 did boot, but no screen, just some
flashes. No text or graphic screen. I did see the tumbleweed logo, but that was
it. Also noting strange in the log files. 

I just had a new computer. Installing tumbleweed did not work because the
kernel of the installer image did not boot properly. I therefore installed
openSUSE Leap 15.0 first, then upgraded to tumbleweed. Then i got in the same
problem like described here. I previous got the live tumbleweed image (version
20181224) working by setting the kernel option "xvideo=1920x180". This also
resulted in flickering screens, but that was related to wayland, recording to
the journal. So choosing Xorg would keep me out op those problems. I therefore
was not expecting problems when upgrading to tumbleweed. 

I had the 4.12 kernel from Leap 15.0, which worked, so i have kept this to boot
the system, which worked. I also booted the 4.19 kernel and uses ssh to log in
remotely. This to find a difference in the log, but the only difference between
a working kernel and 4.19 i found is below.
Kernel 4.12:
[    3.626842] [drm] Initialized i915 1.6.0 20171222 for 0000:00:02.0 on minor
0
[    4.426469] [drm:intel_dp_start_link_train [i915]] *ERROR*
[CONNECTOR:58:eDP-1] Link Training failed at link rate = 270000, lane count = 2
Kernel 4.19:
[    3.393198] [drm] Initialized i915 1.6.0 20180719 for 0000:00:02.0 on minor
0
(note the different date on the i915)

Using the "xvideo=1920x180" kernel parameter was not recommended, so i did not
tried this. I looked at this bug, since it described my problem. I just found
that (for me) the option "i915.fastboot=1" solved my problem with the 4.19
kernel. It now boots properly, suspend works.

May be this can help some others.
