I believe lp:1863489 is a duplicate of this, but the symptom is powertop showing that the i915 device is not dropping into RC6 or lower power state. I was able to reproduce this on my laptop and after installing the above 5.3 test kernel, powertop is now showing RC6 usage > 90% when my desktop is idle.
The 5.3 test kernel Seth generated worked for me. I also tried the 5.4 test kernel Andrea built which also showed RC6 usage > 90% via powertop. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1853044 Title: 5.3.0-23-generic causes fans to spin when idle Status in linux package in Ubuntu: Incomplete Bug description: After upgrading to 5.3.0-23-generic the fans in my machine don't stop running. They always sound like something is utilizing CPU - even with no applications running after boot. If I boot back to 5.3.0-19-generic it's fine.
