I installed the HWE kernel using : $ sudo apt-get install linux-generic-hwe-20.04 What is the recommended way to remove it and go back to the regular kernel again? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu.

I suppose it should be fixed now in 5.4.0-67... * Focal update: v5.4.88 upstream stable release (LP: #1913223) - Revert "drm/amd/display: Fix memory leaks in S3 resume" -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in

Also confirm this on 5.4.0-66, after upgrading from working 5.4.0-65. 20.04 and Radeon rx 550 + hdmi connection. Please, update this bug if/when it gets fixed in the next 5.4.0-67. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in

@Daniel van Vugt That's a good idea. Thank you. I didn't know what the HWE kernel was. This explains it nicely https://askubuntu.com/questions/248914/what-is-hardware-enablement-hwe -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux

As a permanent fix you can apply right now, you might wish to jump to the HWE (5.8) kernel: sudo apt install linux-generic-hwe-20.04 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu.

Can also confirm rolling back to 5.4.0-65-generic fixes the issue. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1916950 Title: [amdgpu] Screen fails to wake up after sleep using

Everything was working fine for me up until I created this bug. I checked dpkg logs + my reboot times and it's when I booted from 5.4.0-65 to 5.4.0-66 that this broke. So this adds up nicely  -- You received this bug notification because you are a member of Kernel Packages, which is subscribed

Sorry, I read that wrong. The fix is in the 5.8 HWE kernel already. ** Changed in: linux-meta-hwe-5.8 (Ubuntu) Status: Confirmed => Fix Released -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu.
