hi guys
I wonder, I cannot boot Fedora without - amd_iommu=off - that's the
first issue. You guys?
I'm on Lenovo Ideapad E485 with AMD Ryzen 5 2500U & F28.
Second issue is - I use external monitor (via HDMI in "join" setup) and
if system went to sleep or HDMI got disconnect then laptop's display
would show something that I do not think many of you might have seen,
unless you are middle-aged at least - it's noise of that kind like in
old days tube TVs would show when signal was lost.
It looks very funny but also so very wrong :)
But when displays both are okey, and when I lock gnome(@Wayland) session
and unlock/login again then both screens would be ... kind of blinking,
infrequently. Reboot is needed to get rid of blinking.
I've tried kernels up to 4.18.5-200.fc28.x86_64
Care to share your thoughts?
many thanks, L.
