> battery You can do a bunch of things around under-volting, governor changes, powertop tuning, profile settings, tlp, etc. to improve battery on arch. Helped me, at least. > disable the NVidia card You shouldn't need a driver to disable it. I switched to arch specifically because gpu switching on manjaro was a nightmare; the arch wiki did it for me: https://wiki.archlinux.org/index.php/Dell_XPS_15_9570#NVIDIA_Optimus https://wiki.archlinux.org/index.php/Dell_XPS_15_9570#NVIDIA... It's for a different machine, but it should still provide a decent starting point. > modem not work Drivers, probably? Not many laptops have them. > light sensor Try this to check: `find /proc /sys | grep -ie brightness -e light -e lux -e lumin`. If that doesn't work, `sudo modprobe -a tsl2550 isl29003 isl29020 apds9802als apds990x bh1770glc bh1780gli` and run the find command again, or try `sensors-detect`/`i2cdetect`. Never configured personally, but these two packages look promising: * https://github.com/mikhail-m1/illuminanced https://github.com/mikhail-m1/illuminanced * https://cgit.chrisoft.org/lightsd.git/ https://cgit.chrisoft.org/lightsd.git/ If you feel like re-implementing, gnome also made one: https://github.com/hadess/iio-sensor-proxy https://github.com/hadess/iio-sensor-proxy > How to disable the "Hot Corner" in Gnome Not what you want to hear, but... don't use gnome. It's not built for tweaking as much as other things are. Something like KDE is orders of magnitude more tweakable, or something simpler like budgie might fit your use case. Personally I like i3-gaps, but that's definitely more advanced. Any way, if you want to disable it, you actually have to install an extension to do it. More info here: https://michigantechit.teamdynamix.com/TDClient/KB/ArticleDet?ID=58106 https://michigantechit.teamdynamix.com/TDClient/KB/ArticleDe... As you said, documentation is awesome. Arch wiki is great.

You shouldn't have to undervolt to get normal battery life, though. The OS should be running only the services you actually need. I always thought Linux was much better at this than Windows. Have the tables turned?

  Linux is indeed better about this, I'm more mentioning it as a general power-saving technique. Windows has something equivalent to schedulers with its "power plan" options, and comes on "balanced" by default; some performance cost for better battery. Linux is better at fewer services, but takes more work to optimize for particular hardware (especially as many drivers don't have first-party linux support, and some times don't use all power-saving features). Often it takes some tweaking to get this working at the same level. It has gotten better with the hard work of lots of people (in that it's actually possible with tweaking now where it wasn't at all before), but there's still some room to improve. Of course, more mfgs could also support linux; that would make it much easier. Or better yet, open-source the driver so it can get better.

Thank you for your hints. I didn't actually mean this as a request for support but rather as a list of things I was facing that were/are hard to solve and I've been using Linux for 10 or so years. (I'm using bspwm, the Gnome Hot Corner thing was just another example, it shouldn't require an addon to disable that)
