I experienced the same display freezing issues, though I could not find any logs related to the issue. It appeared as if the freezes never happened from the logs. Then I installed the amdgpu drivers from the AMD repo and... it got worse. Instead of just display freezes, audio and input also froze during gameplay or even just watching YouTube videos. This made me think that the issue might not be related to the GPU but to the CPU (iGPU) instead. Researching again with that in mind, I found others posting about similar issues: https://bugs.launchpad.net/ubuntu/resolute/+source/linux/+bug/2149877, https://discourse.ubuntu.com/t/micro-stutters-with-ubuntu-26-04-lts-on- amd-hardware/84032, https://askubuntu.com/questions/1566352/problem-z- ubuntu-26-04-lts.
There were several workarounds proposed. I decided the best and cleanest way for me would be to upgrade the linux kernel from proposed 7.0.0-26. So I did: cat << EOF | sudo tee /etc/apt/sources.list.d/proposed.sources Types: deb URIs: http://archive.ubuntu.com/ubuntu Suites: $(. /etc/os-release && echo $VERSION_CODENAME)-proposed Components: main restricted universe multiverse Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg EOF sudo apt update sudo apt install -t resolute-proposed linux-generic Official docu on how to enable proposed: https://documentation.ubuntu.com/project/SRU/reference/enable-proposed/ This fixed the issue for me. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2150776 Title: Ubuntu 26.04 GNOME Wayland: random short display/presentation freezes on AMD RX 7900 XT while apps continue running To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2150776/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
