Hi I in Thinkpad X1 8th generation I installed finally Ubuntu 20.04 and relevant trinity package from the pre-stable release. Now when the machine is running on batteries and is not used for couple of minutes the screen brightness is dimmed down, but the machine freezes, and has to be rebooted. Is that an Ubuntu bug? Or trinity's fault.
