[Desktop-packages] [Bug 1980933] Re: Blanked screen doesn't wake up after put into powersave
Yes, problems in the amdgpu kernel module are a common cause of such freezes. We can only suggest you try a newer kernel: Latest stable: https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.18.10/amd64/ Latest development: https://kernel.ubuntu.com/~kernel-ppa/mainline/drm-tip/2022-07-08/amd64/ ** Tags added: amdgpu ** Summary changed: - Blanked screen doesn't wake up after put into powersave + [amdgpu] Blanked screen doesn't wake up after put into powersave ** Package changed: mutter (Ubuntu) => linux (Ubuntu) -- 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/1980933 Title: [amdgpu] Blanked screen doesn't wake up after put into powersave Status in linux package in Ubuntu: New Bug description: This is *similar* to #1968040 but I'm raising it as a separate issue as the workarounds there do not work for my system suggesting that this is indeed a separate bug. When allowing the system to blank the screen, it becomes impossible to awaken the screen some unknown length of time after DPMS poweroff is triggered. Neither the keyboard nor the mouse can be used to trigger the screens to power back on again once powered down by DPMS. My system is a custom-build desktop PC with a discrete AMD 6600XT GPU and two external 4k monitors. I have tried the workarounds in the above bug and neither worked. Namely pressing ctrl+alt+f1 (nor any other f-keys in combo with ctrl+alt) does not bring the monitors back to life, and adding MUTTER_DEBUG_ENABLE_ATOMIC_KMS=0 to /etc/environment does not change the behaviour in any way. The system is still responsive to the network and I can SSH into the box to investigate when in this scenario.
