5.4.0-40 and xorg-server (pkg: xserver-xorg-core)
2:1.20.8-2ubuntu2.1 I find AMD SOC Radeon LTSP clients
boot to a fuzzy (but readable) LightDM, and if I login,
the desktop and everything else in Xubuntu is blurry/fuzzy
and stays that way. <br>

LightDM to timeout to a blank screen (the default X
screensaver 10 minutes) then move the mouse, LightDM is
now sharp and logging in to Xfce all remains sharp.</font></p>

screensaver do any extra or different hardware detection?<br>
