Yes, I think your definition is correct. This bug is/should be primarily about the virtual keyboard not appearing when using the Xorg session, even though all (ACPI) events for tablet mode are handled properly. It seems to work fine within the Wayland session and it worked fine in Xorg in previous Ubuntu releases.
And we have a second issue, which causes similar issues also under Wayland. It happens when 2-in-1 devices don't switch to tablet mode under Ubuntu. This issue was also introduced with GNOME 3.36/Ubuntu 20.04. It would probably be a good idea to open another bug report for each unsupported device, I guess? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1866556 Title: On-screen keyboard (OSK) on touch screen does not seem to work at all under Xorg in Focal Status in gnome-shell package in Ubuntu: Confirmed Bug description: After upgrading to Focal, the OSK never appears for me under Xorg - Does not appear automatically when selecting text fields - Cannot be summoned on-demand by swiping up from bottom screen border (which worked on Eoan also under Xorg) Under Wayland, both these things continued to work after the Focal upgrade if the laptop is in tablet mode (but not if it is in regular laptop mode - not sure if this changed on upgrade). I could repro this on two "2-in-1" fold-able laptops: Dell XPS 9575 2-in-1 Asus Zenbook flip UX561UD. (Note: There was an older bug #1760399 about OSK not working under Xorg, but this one was fixed in Cosmic) ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: gnome-shell 3.35.91-1ubuntu2 Uname: Linux 5.5.4-050504-generic x86_64 ApportVersion: 2.20.11-0ubuntu18 Architecture: amd64 CurrentDesktop: ubuntu:GNOME Date: Sun Mar 8 17:33:36 2020 DisplayManager: gdm3 InstallationDate: Installed on 2018-09-13 (541 days ago) InstallationMedia: Ubuntu 18.10 "Cosmic Cuttlefish" - Alpha amd64 (20180912) RelatedPackageVersions: mutter-common 3.35.91-1ubuntu1 SourcePackage: gnome-shell UpgradeStatus: Upgraded to focal on 2020-01-04 (63 days ago) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1866556/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
