Title:
CPU frequency stuck at minimum value..again Ubuntu 20.04.3
Status in thermald package in Ubuntu:
In Progress
Bug description:
I would really like to find out why my cpu's keep reverting back to a cpu
powersave mode after I get a kernel update then reboot.
I cleaned my laptops vent but this seems to happen whenever a new
kernel is updated and installed.
