Comment 17 for bug 1716857

There are two workarounds mentioned: swap to lightdm and manipulate gdm3
start. I think you refer to the gdm3 startup changes when you say it causes
problems with suspend/resume (which I didn't try).
The other workaround is changing display manager to lightdm (or sddm, the
KDE display manager).
swapping to lightdm has not caused any suspend/resume problems for me on
the two Optimus laptops I used, so I think the lightdm workaround is ok.
It was the default display manager of ubuntu for a long time and is still
the default for xubuntu.
