Description: connecting an external monitor through miniDisplay port breaks both the external display and internal display.

External display - see 1/4th the display active only in the upper left quadrant of display.
Internal Display - see top half of display active only.

With both of these the mouse does not travel outside of cropped display region - indicating the resolutions for both displays are not maintained when connecting an external monitor

Oodly on first boot with upgrades - new message indicating GNOME Desktop Manager needed for screen lock (Which is disabled on this system).

- Apologies - Message is GNOME Display Manager not Desktop Manager
Comment by freswa (frederik) - Sunday, 08 March 2020, 22:23 GMT
Could you please try this on a different system and check if it happens indepent of hardware?
Comment by grokArch (grokArch) - Monday, 09 March 2020, 16:13 GMT
I have verified that the external monitors (2 different ones) are working as expected - so it is related to the updates form yesterday on this specific system.

Screenshot 20200308- is top half of internal screen when first attaching miniDisplayPort

Hi Guys :)

I also did a full system upgrade yesterday which brought my Gnome from 3.34 to 3.35 and I also have this problem. There are two scenarios I'm able to reproduce:

1. Set screen scaling at 100% for the laptop internal display
2. Connect external monitor
3. Laptop internal display only shows top half of the screen and external monitor only shows upper left quarter
4. Disconnect the external monitor
5. Back to normal on the laptop display

1. Set screen scaling at 200% for the laptop internal display
2. Connect external monitor
3. Laptop internal display only shows top half of the screen and external monitor only shows upper left quarter
4. Disconnect the external monitor
5. The laptop display remains broken until I reboot

I'm using Dell XPS 13 that has the resolution of 3200x1800 and tested with two LG 4K monitors over a Thunderbolt (USB-C) cable.

Attaching the photo of what happens.

Thanks,
Greg

looks like GNOME fixed in their source
- https://gitlab.gnome.org/jadahl/mutter/-/commit/531a195cf184b3d81e333dedf83bc51c3f37e97b has been updated

- when can we expect update in Arch Package?

Similar kind of thing happens on my kde desktop.
After first reboot. I faced the exact issue.

Then I reinstalled plasma plasma-meta and sddm.
Now when I connect the external monitor, The laptop screen is ok, but the external monitor is out of whack. As in it doesn't scale properly. Previously this used to work with the same display resolution configuration for the laptop and monitor screen as now.
