I noticed that on 5.0.0-25-generic the module snd_hda_codec_hdmi is loaded, which is not true for 5.0.0-23-generic.
http://changelogs.ubuntu.com/changelogs/pool/main/l/linux-hwe/linux- hwe_5.0.0-25.26~18.04.1/changelog * Unhide Nvidia HDA audio controller (LP: #1836308) - PCI: Enable NVIDIA HDA controllers There was a fix to make nvidia audio controller visible that causes that module to be loaded, forcing the dedicated video card awake. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1836308 Workaround, adding: blacklist snd_hda_codec_hdmi options snd_hda_intel enable=1,0 on /etc/modprobe.d/blacklist.conf fixes the problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1840835 Title: High power consumption using 5.0.0-25-generic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1840835/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
