@fossfreedom, apart from the wm used (you budgie-wm and me gnome-shell) I see that your HDMI devices are identified as brcm:soc while mines are identified as fef00700 and fef05700.
Maybe we are using different eeprom version. I'm using latest stable from here: https://github.com/raspberrypi/rpi-eeprom root@fpgrpi:~# rpi-eeprom-update BOOTLOADER: up to date CURRENT: mar 06 jul 2021 10:44:53 UTC (1625568293) LATEST: jue 29 abr 2021 16:11:25 UTC (1619712685) RELEASE: stable (/lib/firmware/raspberrypi/bootloader/stable) Use raspi-config to change the release.

Maybe you can update it to the newest version just to try. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1946368 Title: HDMI output freezes under current/proposed impish kernels To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi/+bug/1946368/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
