Marking this verified again, as it was verified as fixed in version
3.36.4-0ubuntu0.20.04.1 (see [1] and [2]), so given that the changes in
.2 [3] do not affect this behavior, we can safely consider it already
verified.

Hello Daniel, or anyone else affected,
Accepted mutter into focal-proposed. The package will build now and be
available at

few hours, and then in the -proposed repository.
Please help us by testing this new package. See
OK so there are still bugs. I suggest we wait until *after* 3.36.4 is
released to focal and everyone updated, then please open new bugs by

For me, it doesn't seem to be fixed.
I have installed mutter 3.36.4 and rebooted. When I set my external 4k
AOC display to 200% and the internal monitor to 100%, it works. However,
if I increase the scaling of the internal monitor to 125% in display
settings, I get the both screens turn black and
This specific bug can be then considered fixed.
The other issues, like bug #1875285 is still under studies, but looks
like it's a correlation of nvidia drivers and some specific cards (as
this update fixes that problem for a subset of them as well).

One problem however is If I have the scaling set at e.g. 175% full screen apps

I've tried this from pop!_os 20.04, nVidia 2060 super GTX, 4k monitor.
Starting off in 100% scaling, I select 125% scaling. Before enabling
proposed, this resulted in the screen switching off.
Since enabling proposed and installing the updated packages, this now
doesn't switch the screen off,
update mutter package in fossa-proposed works for me.
Ubuntu 20.04, nVidia 1060 GTX, 4k monitor, 150% scaling
Thanks !

Ryan,

Please don't discuss them here.

Just to add I found that on the unscaled screens the text and general
look was a little fuzzy. I assume this is something to do with the
scaling going on. Also if fractional scaling is turned off I cannot set
the 4k screen to 200% on its own as all screens then get set to 200%.
I know its not
I tried what Ryan did via Display Settings and it still made all screens
200% instead of 100/150/100 for me.

Nvidia driver support for the Ubuntu fractional scaling patch is
somewhat random at the moment. And I don't mean to blame Nvidia, it's
probably something we did wrong. Just saying various Nvidia users
experience different issues:
* Screen turns off (bug 1873403)
* Screen stays on but jumps to
Ive just tried this again this morning
1. 2560 x 1440
2. 3840 x 2160
3. 1920 x 1200
I set fractional scaling to 1.50 on screen 2 (Others 100%)
For the session it works perfectly fine, But after logging out and
logging back in the settings do not get saved (Nvidia gtx 1080 with 440
driver)
Any ETA at all, by chance?

I want to add something here: I'm using the xrandr scale setting since
19.04 as fractional scaling has never worked on Ubuntu and X11. In the
last versions the monitor settings weren't stored.
In my experience when setting the display resolutions / scaling with
xrandr, my NVIDIA card would always
I have 2 monitors and one HDTV being used as a monitor. Everything was
fine on Pop OS 19. I upgraded to Pop OS 20 (which I assumed bumped me to
the latest Ubuntu) and now I'm having fractional scaling issues.

Middle HDTV = 4k HDTV in landscape mode

Findings so far:
1. You really need the uninitialized variable fixed first, or behaviour
can be random (bug 1874207).
2. The current spec can be found at:
