--- Comment #6 from Hin-Tak Leung htl10@users.sourceforge.net --- A me-too. Although I have something to add: if I switch to a VT, I can suspend and resume. However, Xorg after suspend is still f*cked - i.e. I can switch to a text VT, suspend, resume in the VT and still have an operating VT; but if I try to switch back to Xorg, the machine hangs at this point.
Hardware is (lspci -v)

Lastly, it appears that the last time I suspend and resume okay was with 4.20.16-200.fc29.x86_64 ; 5.0.6-200.fc29.x86_64 and 5.0.7-200.fc29.x86_64 both hangs on waking. I have no data between. Although, as noted, suspend and resume in VT and staying in Vt, works - just that X is no longer functional after resume.
