--- Comment #27 from Luigi Cantoni <lui at fgcint.com> ---
It appears I am not using glk as that is not in my dmesg/journal files. Thus I
think I am not loading it.
I just checked out comment#18 and that made no difference, same problem.

I just tested again for i915.enable_fbc=0 Still there but using the check that
Daniel suggested looks like it is going wrong.

[root at test tmp]# dmesg | grep -i "kernel command"
[    0.116842] Kernel command line: BOOT_IMAGE=/vmlinuz-4.20.5-200.fc29.x86_64
root=/dev/sda3 ro resume=/dev/sda2 i915.enable_fbc=0 rhgb quiet
LANG=en_AU.UTF-8
[root at test tmp]# cat /sys/module/i915/parameters/enable_fbc
0

I thought I was setting the parameter correctly but it appears I am not.
Suggestion?
I certainly hope that once set correctly it fixes it because then we will all
be happier.
