Hi!
At each new Fedora release I have 3 thinkpads to 'upgrade'. In fact I
do fresh installs for those and have a list of steps to perfom so I
don't forget anything (list which I maintain and update at each
release as things do change over time).
Desktop scaling is always tricky and this time I only get it to work
on 1 of those 3 Thinkpads. They are 3rd, 6th and 8th generation ones.
Currently it only works on the 8th gen one.
I type this:
gsettings set org.gnome.mutter experimental-features
"['scale-monitor-framebuffer']"
On 3rd gen I can only do 100% and 200% and on 6th gen I cannot even do
200% as it says there is some HW limitation message preventing to
change anything.
Any advice on how to troubleshoot the issue would be very welcome.
Thank you very much.

ok so I seem to have narrowed down the problem to the external Logitech
keyboard. When I unplug it I can do fractional scaling on the LCD with
no monitor connected, I can also do it with 1 external monitor
connected, but it stops working at 2 monitors.
Could it be linked to g810-led from copr lkiesow/g810-led? I'm not with
the laptop right now, I'll try to uninstall next time and will test
again. In the meantime, i'm still open for ideas to troubleshoot and/or
file a bug somehwere.
Thank you.
