I'm running Xubuntu on mine and it works fine. Battery life goes down pretty quick when sleeping, and battery life is definitely lower than Windows, but I can still get 4-5 hours of actual work on it.
Thank you for confirming.
I guess I will have to wait until an improved version of Framework that supports proper sleep.
