Trying to test with vanilla Xorg by stopping gdm3 and using Xorg by itself:
0. Install xterm since we are going to use it later. 1. Switch to tty3 by using Ctrl-Alt-F3 sudo systemctl stop gdm3 sudo Xorg & DISPLAY=:0 xterm 2. Switch to blank Xorg session using Ctrl-Alt-F1, then in xterm run xev Check touchscreen function: the cursor should follow the touch screen, and if touching the xev test region, xterm should display some messages. 3. Switch xev to background by Ctrl-Z then bg command, then suspend system: systemctl suspend 4. Resume after a while and check touchscreen On one of our DUTs, the issue is not reproducible with the above configurations. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-input-libinput in Ubuntu. https://bugs.launchpad.net/bugs/2087831 Title: touchscreen has no response after resume from suspend in Xorg session Status in OEM Priority Project: New Status in xserver-xorg-input-libinput package in Ubuntu: Incomplete Bug description: The touchscreen has no function after suspend resume in Xorg session. --- ProblemType: Bug ApportVersion: 2.28.1-0ubuntu3.1 Architecture: amd64 CasperMD5CheckMismatches: ./.disk/casper-uuid-generic ./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 DisplayManager: gdm3 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-hwe-20241111-227 DistroRelease: Ubuntu 24.04 InstallationDate: Installed on 2024-11-11 (0 days ago) InstallationMedia: Ubuntu OEM 24.04.1 LTS "Noble Numbat" - Release amd64 (20241110) NonfreeKernelModules: nvidia_modeset nvidia Package: gnome-shell 46.0-0ubuntu6~24.04.5 [origin: unknown] PackageArchitecture: amd64 ProcVersionSignature: Ubuntu 6.8.0-48.48-generic 6.8.12 RelatedPackageVersions: mutter-common 46.2-1ubuntu0.24.04.2 Tags: noble third-party-packages Uname: Linux 6.8.0-48-generic x86_64 UnreportableReason: This does not seem to be an official Ubuntu package.
