FYI, in case anyone wants to add their monitor (and whether it succeeds or fails at suspending with the Ubuntu raspi kernel) to this ticket:
$ cp /sys/devices/platform/gpu/drm/card1/card1-HDMI-A-1/edid hdmi0-monitor.edid $ cp /sys/devices/platform/gpu/drm/card1/card1-HDMI-A-2/edid hdmi1-monitor.edid As you may guess, hdmi0-monitor.edid is the EDID for the monitor plugged into HDMI0 (the socket closest to the USB-C power port on the Pi4, and the socket closest to the uSD slot on the Pi400), whilst hdmi1-monitor.edid is the EDID for the monitor plugged into HDMI1. If you have no monitor connected to a socket, you'll still get an EDID file but it'll be 0 bytes. A valid EDID file should be 256 bytes (or more? I forget the details of EDID, but there's some extended blocks I vaguely recall). Upload valid EDID files to https://www.edid.tv/edid/upload/binary/ if you wish (bear in mind this will share the serial # of your monitor but I don't think there's any particular security risk in that), and add the link here along with whether or not this particular monitor suspends successfully or not. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1998716 Title: [raspi] Ubuntu 22.10 does not turn off monitor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi/+bug/1998716/+subscriptions -- desktop-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
