When using xorg-x11-server-1.20.5 my external monitor (Dell U2515H) stays blank. xrandr/settings does see the monitor correctly but you can not show any content on it. I usually have the external monitor set to being the primary and the internal laptop (Dell Latitude E5570) display to secondary, below the primary. Tried removing monitors.xml and the external display shortly fires up but then goes blank again. Filed a bug already:

Bodhi is disabling automatic push to stable due to negative karma. The maintainer may push manually if they determine that the issue is not severe.
I can confirm @freddyw's findings. With this update I can no longer use my external display with my Thinkpad T480s laptop. I'll add more details to the linked bug report. Please do not push.
External monitor worked on Cinnamon spin, but only after I opened laptop's lid (enough for internal screen to blink) every time monitor was waking from power saving mode or after a mode change (start-up, user switch).
External monitors stopped working both via a USB C dock or via HDMI.
Issue was resolved after downgrading so it is definitely this update that is causing the issue.
Packages I downgraded with to fix the issue:
xorg-x11-server-common-1.20.4-3.fc30.x86_64.rpm
xorg-x11-server-Xorg-1.20.4-3.fc30.x86_64.rpm
xorg-x11-server-Xwayland-1.20.4-3.fc30.x86_64.rpm

I see some similar issue here. When I try changing the resolution of a laptop display with xrandr, the display gets black and never get back.

Also redshift stopped changing colours on 1.20.5.
