Those errors aren't printed when booting with hdmi connected. Attached related dmesg output. Device `01:00.1` is suspended.
I can confirm from documentation about this laptop (Acer aspire A715-71G) that the embedded display is connected to the intel GPU (eDP) and the HDMI port is connected to the nvidia GPU, this must be the most probable case on these laptops. Otherwise, maybe `01:00.1` device wouldn't exist. When booting with intel gpu only, HDMI interface isn't listed on xrandr and HDMI screen has no input. This is supposed to happen as HDMI is connected to nvidia and nvidia should be powered off, right? This also happens with previous kernels and should not be related with this bug. ** Attachment added: "dmesg_#37~lp1907212+4_hdmiconnectedbeforeboot_intel.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1907212/+attachment/5445188/+files/dmesg_%2337~lp1907212+4_hdmiconnectedbeforeboot_intel.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1907212 Title: Power consumption regression after upgrade to 20.10 5.8.0-31-generic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1907212/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
