While I'm fixing this upstream to show all the values and we're SRUing it to ubuntu stable versions, I've made a ppa for hisute (21.04) and focal (20.04) so you can test it (packages are building right now, so may take some moments):
https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/4565/ Note: since it's preferable not to change design in a SRU, the values will be still limited to 5 and will shoe exactly like before, but now selecting higher values, more scaling values will be visible and selectable. ** Also affects: gnome-control-center (Ubuntu Hirsute) Importance: Undecided Status: New ** Changed in: gnome-control-center (Ubuntu Hirsute) Importance: Undecided => Medium ** Changed in: gnome-control-center (Ubuntu Hirsute) Status: New => Triaged ** Changed in: gnome-control-center (Ubuntu Hirsute) Assignee: (unassigned) => Marco Trevisan (Treviño) (3v1n0) ** Also affects: gnome-control-center (Ubuntu Focal) Importance: Undecided Status: New ** Changed in: gnome-control-center (Ubuntu Focal) Importance: Undecided => Medium ** Changed in: gnome-control-center (Ubuntu Focal) Status: New => Triaged ** Changed in: gnome-control-center (Ubuntu Focal) Assignee: (unassigned) => Marco Trevisan (Treviño) (3v1n0) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1795483 Title: Experimental setting to enable fractional Hi-DPI scaling offers no option larger than 200% on 15.6 inch, 3840 x 2160 pixel display (Dell XPS 15 9575) Status in gnome-control-center package in Ubuntu: Fix Committed Status in gnome-control-center source package in Focal: In Progress Status in gnome-control-center source package in Hirsute: In Progress Bug description: [ Impact ] On my laptop's 15.6 inch, 3840 x 2160 pixel (282 PPI) display, the available scaling options in the gnome-control-center display settings are limited to 100, 200, 300, and 400%. This is insufficient as 200% is too small and 300% is too large. The missing fractional scaling options are dealt with in bug #1687246. However, the currently available experimental feature to enable fractional scaling (provided in the bug description of #1687246) does not solve the problem on my machine: gsettings set org.gnome.mutter experimental-features "['scale-monitor- framebuffer']" After applying and rebooting, the options offered change to 100, 125, 150, 175, and 200%. Note that there is no value larger than 200% which is too small on this display at least for me. In addition, the 25% steps enabled by the experimental option seem too far apart. With 200%, I am using a font scaling value in Gnome Tweaks of 1.20, so I suppose a fractional scaling of approx 240% would be equivalent. In bug #1687246, Daniel van Vugt (vanvugt) advised to open a new bug for gnome-control-center and added that "gnome-control-center seems to limit the scale to 200% on some machines, 300% on others. And I think I have seen 400% offered in some cases. I don't know why, but the inconsistency is definitely annoying." [ Test case ] In a setup with a display with HighDPi resolution (higher than 2880x1800) - Open gnome-control-center display panel - Scaling should show 5 level buttons to select - Selecting higher values will show all the selectable values closer to the chosen one - Any value could be used from 100% up to 400% (maximum varies on resolution) [ Regression potential ] Control center won't show any scaling value, or scaling value may be wrong. --- ProblemType: BugDistroRelease: Ubuntu 18.10 Package: gnome-control-center 1:3.30.0-0ubuntu1 Uname: Linux 4.19.0-041900rc5-generic x86_64 ApportVersion: 2.20.10-0ubuntu11 Architecture: amd64 CurrentDesktop: ubuntu:GNOME Date: Mon Oct 1 19:29:11 2018 InstallationDate: Installed on 2018-09-13 (17 days ago) InstallationMedia: Ubuntu 18.10 "Cosmic Cuttlefish" - Alpha amd64 (20180912)SourcePackage: gnome-control-center UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1795483/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
