Hi Daniel and Yao, Sorry for jumping into this issue.
Given that the issue affects all touch screens with nVidia GPUs, we may need to fix for ODM platforms with the combination. Since many OEM platforms are starting QA testing for the new generation GPU in March, do you think we can complete the SRU to fix this issue before the OEM QA testing begins? Thank you again for the support. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/2087831 Title: [SRU] On a laptop with NVIDIA graphics and touchscreen, touchscreen gets disabled after resume from suspend in Xorg session Status in Mutter: Fix Released Status in OEM Priority Project: In Progress Status in mutter package in Ubuntu: Fix Committed Status in mutter source package in Noble: In Progress Status in mutter source package in Oracular: In Progress Status in mutter source package in Plucky: Fix Committed Bug description: [ Impact ] * When user using Ubuntu 24.04, 24.10 with NVIDIA GPU and touchscreen, touchscreen becomes unresponsive after suspend/resume. * This patch addresses the problem by synchronizing enabled state of touchscreen when the device adds into device mapper (which maps touchscreen and display).
