** Description changed: [ Impact ] Double-click actions in GTK4 are hard to trigger with touchscreen input, in X11 only. That is because GTK4 will generally try to verify that the distance between the two clicked locations is very small, but that is difficult to achieve on a touchscreen. Touch input should be excluded by this proximity check, but this doesn't happen in X.org. Upstream bug report: https://gitlab.gnome.org/GNOME/gtk/-/issues/7508 [ Test plan ] 0. Find a touchscreen device (high resolution screen preferred to reproduce issue) 1. Log-in to Ubuntu (on Xorg) 2. Open Nautilus 3. Double tap on a folder, moving the finger from one edge to the other 4. Verify that you navigated into the folder [ Regression test plan ] 1. Log-in to Ubuntu (on Xorg) 2. Open Nautilus 3. Double click on a folder 4. Verify that you navigated into the folder [ Where problems could occur ] The patch only affects X11 and couldn't possibly regress Wayland. The patch affects general input handling in GTK4, so a regression test plan is included to ensure that the same action can still be performed with a mouse too. + [ Other Info ] + + The bug status in resolute and questing is Invalid because there is no + Ubuntu/GNOME on Xorg anymore. + --- ProblemType: Bug ApportVersion: 2.28.1-0ubuntu3.8 Architecture: amd64 CasperMD5CheckMismatches: ./.disk/casper-uuid-oem ./casper/initrd ./casper/minimal.standard.live.hotfix.size ./casper/minimal.standard.live.size ./casper/minimal.manifest ./casper/minimal.standard.manifest ./casper/minimal.standard.size ./casper/minimal.hotfix.size ./casper/minimal.standard.live.hotfix.squashfs ./casper/minimal.standard.hotfix.squashfs ./casper/minimal.standard.hotfix.size ./casper/minimal.hotfix.squashfs ./casper/minimal.standard.live.manifest ./casper/minimal.size ./boot/grub/grub.cfg CasperMD5CheckResult: fail CurrentDesktop: ubuntu:GNOME DistributionChannelDescriptor: # This is the distribution channel descriptor for Ubuntu 24.04 for Dell # For more information see http://wiki.ubuntu.com/DistributionChannelDescriptor canonical-oem-somerville-noble-oem-24.04b-20250714-538 DistroRelease: Ubuntu 24.04 InstallationDate: Installed on 2025-07-15 (15 days ago) InstallationMedia: Ubuntu OEM 24.04.2 LTS "Noble Numbat" - Release amd64 (20250714) Package: libgtk-4-1 4.14.5+ds-0ubuntu0.1 PackageArchitecture: amd64 ProcVersionSignature: Ubuntu 6.11.0-1025.25-oem 6.11.11 Tags: noble Uname: Linux 6.11.0-1025-oem x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sudo users _MarkForUpload: True
