I've been using ubuntu for the last month or so on my laptop and it's been working fine, up until last week. I am using a Dell XPS 15 9570
Nothing has changed except I followed this guide https://medium.com/@maxmckinney/impr...u-b4ff6fb5cf1a to fix palm rejection. I AM NOT SURE IF THIS IS RELATED
Ever since then, any time i open my laptop after closing it it works for about a minute, then freezes for about a minute, and then continues working normally. The battery life has also been horrendous, I used to get ~11 hours, now I get ~6.
This is the output of running
As you can see it's using a lot of power. My battery was at 87% at that moment in time.
I've since reverted the fix for palm rejection, and still having all these issues - so not sure if it's related or not. I'd appreciate any help, I'm considering doing a fresh install of Ubuntu but I'd like to avoid this if possible since I have everything already configured to my liking.
