I can confirm this bug is still there in Ubuntu 20.04 (and from what i did find it already exists at least 13 years!). I think this should get some priority.
I have a Dell XPS13 for 1.5 year now and this haunted me ever since. I recently discovered that i can restore normal operation by temporary unplugging the external power a few times. About 1 in 4 times normal operation is restored. I check this using cpufreq-info | grep MHz -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1769236 Title: CPU frequency stuck at minimum value To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1769236/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
