I have fractional scaling working at 150% on one display and 100% on the other. When I reboot, these settings are forgotten (as well as the relative position of displays).

How do I persist my settings? This is on Ubuntu 19.10.

    first, how did you achieve different scales on each display? – epineda Oct 23 '19 at 01:05
  • It's now a thing. I noticed there is a similar question. I have the same monitor setup as the person who made the post https://askubuntu.com/questions/1150008/can-i-make-display-scaling-permanent-in-19-04 – GlaceCelery Oct 23 '19 at 11:19

    This is what I typed: gsettings set org.gnome.mutter experimental-features "['scale-monitor-framebuffer']" – GlaceCelery Oct 23 '19 at 11:21
  • Have you managed to fix this? Edit: nevermind, I'm using Pop OS and I only had to disable the HiDPI daemon. – Frans Nov 09 '19 at 17:53
  • No I didn't...However I also installed Pop!_OS ...and it works – GlaceCelery Nov 10 '19 at 22:57
  • PS: Setting both displays to 150% causes the same thing. I had tried to do exactly the same thing one 150% and one 100%. This bug happened, so I thought maybe using different values caused it (to be fair, I was surprised that I could set so, because, as far as I remember, in the old version, I could not set two different values on X11), and set both to 150%. The display settings (position, scaling, as well as enable state -- because I have three monitors and disabled the third) were lost on the next log on. – Damn Vegetables Nov 30 '19 at 08:40
  • Same thing happening for me. I set primary display to 125% and secondary to 100%. After a restart, the primary is back to 100%, and also the relative position of the secondary is back to the right of primary, even though I dragged it to the left previously. – dinvlad Dec 01 '19 at 21:25
  • I just installed 20.04 and have exactly the same problem: I set settings that are forgotten on reboot. – Juan Lanus May 11 '20 at 16:21

From: How to Enable Fractional Scaling in Ubuntu 19.04

To enable fractional scaling in GNOME 3.32 on Wayland run:

gsettings set org.gnome.mutter experimental-features "['scale-monitor-framebuffer']"

To enable fractional scaling in Ubuntu 19.04 on Xorg run:

gsettings set org.gnome.mutter experimental-features "['x11-randr-fractional-scaling']"

Once set, you can open Settings > Devices > Screen Display to access additional fractional scaling values, including 125% and 150%.

There are many reports of settings not persisting across reboots:

If you feel your problem is the same file a bug report.

Using fractional scaling with nvidia cards can be problematic with the nouveau (open source) drivers. You may be better served with the drivers direct from nvidia (closed source).

Wrong gsettings?

It could be the wrong gsettings are being run as in this question:

~$ gsettings set org.gnome.mutter experimental-features "['x11-randr-fractional-scaling']"
GLib-GIO-Message: 12:22:36.852: Using the 'memory' GSettings backend.  Your settings will not be saved or shared with other applications.

If that is the case simply use /usr/bin/gsettings command.

Other options

Many use Ubuntu 16.04 with Unity Tweak tool and Font scaling options. For example I have mine set at 1.38 for many years without any problems.
