My issue starts with gdm, with gnome shell taking up to 800% of the cpu and

log into kde from gdm instead of logging into gnome the performance issue ceases
and things go back to normal. If I use kdm as the display manager, launching kde
does not cause any performance issues, and, if I launch gnome from kdm there are no
performance issues either, with gnome shell running normally and not thrashing the
cpu, so from my perspective the issue is gdm. The next question is how do I fix it?
Are you running GNOME under wayland or Xorg?
Could be this. https://bugzilla.redhat.com/show_bug.cgi?id=1517330
Thanks Ed, I tried Gnome under Wayland and Xorg and as documented in the
problem description, even though gnome shell lags with gdm, when gnome
under Xorg is started the lag disappears. The only difference in my case
is that the issue was not caused by upgrading from F26 to F27, which the
problem description seems to be indicating, it was working fine in F27,
until an update I put on caused the issue. If as indicated in the
problem description the gnome-shell issue only happens under Wayland,
does that mean that gdm runs under Wayland, and if so is there any way
to change that functionality to get gdm to run under Xorg until the
Wayland issue is resolved?
regards,
Steve
