I am pretty sure, that these mentioned bugs are same issue. Thanks. I found this enable_rc6 has been removed due to stability issues.

I believe this is the same as https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1853044 and possibly https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1856653. lp:1853044 has test kernels for both 5.3 (https://people.canonical.com/~sforshee/lp1853044/5.3.0-40.32+lp1853044v202002131655/) and 5.4 (https://kernel.ubuntu.com/~arighi/LP-1853044/) containing a patch to fix this. I tried the 5.3 test kernel and powertop is now showing RC6 usage > 90% when my desktop is idle. If this solves the problem for you, I'll duplicate this to lp:1853044. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1863489 Title: intel grafic i915 driver no power saving states rc6 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1863489/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

** Description changed: - It seems that the i915 intel grafic driver in newer kernels (observed with 5.3) doesn't support energy saving. + It seems that the i915 intel graphic driver in newer kernels (observed with 5.3) doesn't support energy saving. How do I know that? Using powertop shows in idle tab the GPU - and this shows only : GPU power on 100% - no rc6 or deeper states are used. For some strange reason also the packet (summery?) shows in all states 0%, although I can observe the individual CPU cores are in different power states. The previous parameter enable_rc6 is not existing anymore. The other possible energy saving parameter enable_dc (if set to 1 or 2) results in log with: - setting dangerous option enable_dc - tainting kernel. + setting dangerous option enable_dc - tainting kernel.

powertop: Take care, maybe you have to scroll down, it is in the middle row below the cpu-cores For some strange reason also the packet (summery?) shows in all states 0%, although I can observe the individual CPU cores are in different power states. Edit: I observed that with Ubuntu Mate 18.04 with new (!) installations. My old installation (kernel 4.15 seems not to be updated to newer version) is not suffered. I have tested also Linux Mint 19.3. Initially (kernel 5.0 if I remember right works) but after update to 5.3 not anymore. So I can exclude hardware as an issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1863489 Title: intel grafic i915 driver no power saving states rc6 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1863489/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
