Regarding #28 "on 20.04 LTS and v5.6 is not working properly with WiFi."
When I first tested Kernel 5.6 branch, the WiFi was broken because of this: https://linuxreviews.org/Linux_5.6.2_Is_Released_With_Intel_Wifi_Fix Now it is working again with the current 5.6 branch. Kernel 5.5 is now EOL (as of 5.5.19 end of April) https://en.wikipedia.org/wiki/Linux_kernel_version_history#Releases_5.x.y Intel should do better QA for their iGPU and WiFi and try to port it to all stable LTS branches aka 5.4.x and 5.6.x If you still have issues with Intel i915 on 5.4.x, you can use the following one-liner to install 5.6.x which curl >/dev/null 2>&1 || sudo apt-get install -qq -y curl; for version in $(curl -sL https://kernel.ubuntu.com/~kernel-ppa/mainline/ | tac | grep -Pom1 '(?<=")v5\.6\.[0-9]+/'); do for deb in $(curl -sL https://kernel.ubuntu.com/~kernel-ppa/mainline/${version} | grep -Pom4 '(?<=")linux-(headers|image- unsigned|modules)-5\.6\.[^"]+[0-9]+(-generic_5\.6\.|_5\.6\.)[^"]+.(amd64|all)\.deb'); do curl -sLo ${deb} https://kernel.ubuntu.com/~kernel- ppa/mainline/${version}/${deb}; debs="${debs} ${deb}"; done; sudo dpkg -i ${debs}; done If you need to go back to legacy Ubuntu 20.04 LTS Kernel and remove Linux Kernel 5.5 and 5.6 dpkg --get-selections | awk '/linux-.*-5\.[5-6]/ { print $1 }' | xargs echo sudo apt-get purge -y -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1868551 Title: Intel GPU Hangs : random screen freezing w/ Ubuntu 20.04 (Linux 5.4) i915_active_acquire To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1868551/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
