You have to go to bios and disable secure boot, then the battery doesn’t get drained anymore when the lid is closed. You also have to disable ps2 mouse emulation in bios, the mouse hypersensitivity goes away after that. I also enabled large text in accessibility so the text size is perfect and super high res with the 3:2 aspect screen, it’s fantastic.
I just bought the framework and running ubuntu 21.10. I had some of the problems you mentioned but the forum has solutions to many. It’s a new product, and specially with Linux, I knew there would be some problems. You have to be willing to solve these problems o/w you should stay away from buying new hardware from a startup.
