Bug Description

https://gitlab.gnome.org/GNOME/gnome-shell/issues/331

---

I run my screen on 100% scaling even though the ubuntu default for my 2560x1440 screen is 200%. After resume from suspend it's common for GDM to display at 200% and only after switch back to 100%. Sometimes this extends to after unlock with the mouse cursor being double size but only when hovering over the gnome shell top bar. I tried taking a screenshot but running the screenshot app fixed it and the cursor was normal sized again.

I've now submitted or subscribed to several gnome-shell and gdm3 bugs. The 18.04 transition from unity to gnome-shell was clearly a step back in terms of polish of the desktop.

The lock screen and login screen graphics are provided by the the gnome-shell package.

I think the problem here may be that some instances may be running as a different user (gdm), so your own personal settings won't apply to those.

summary: - Screen size is wrong on resume from suspend
+ Personal scaling settings not used on the unlock screen

But what's strange is that the issue only happens momentarily and when returning from suspend. If I lock the screen it's correct and after a few moments after suspend it's correct again.

This is not the same bug. I can't reproduce it anymore since gdm is no longer slow on resume. But is it really Ubuntu process to have the user submit bug reports upstream?

Yes, upstream requires bug reports from someone who experiences the bug.

Just had the same thing happen even with gdm not being slow. Flashes for less than a second and now my pointer is at 200% when over the top bar. Trying to take a screenshot resets it again so I can't show it.

This happens to me 100% of the time now and is extremely annoying. Issues like this have made the 18.04 GNOME transition a clear step back in desktop polish.

This bug doesn't exist on Wayland. It does seem like GNOME developers don't care about Xorg anymore and these kinds of bugs won't get fixed.
