              My chrome os dev setup.md
            
          
    Ran on my Dell XPS 15 9560 (4k) using brunch with the rammus recovery
Why?

Mostly funs.
Findings

Great things:


Battery seem to be better than linux, equal to windows.
With normal usage laptops doesn't get hot even while wathcing 4k videos on youtube. Note that this also results in way less often the fan ramping up :)
Crostini works great and is by default setup to passtough localhost.
Crostini can run ubuntu, fedora, arch and more
Docker runs perfectly fine on Crostini compaired to the windows subsytem this is much better
Touchpad*(-gestures)* and Touchscreen*(-gestures)* works great and in my opinion better than on linux
Android apps work like they do on any other chromebook
standby works with TMP disabled and s3_suspend add to the boot options
Wayland apps run amazingly under crostini

Worse things.


Updates can break the device
Xorg Desktop Linux apps ran via crostini run terrable so forget using things like vscode
Linux sometimes takes forever to do certain things like finishing an update or starting to install something seems to be some sort of IO issue (Seems to be only an issue in debian the default linux distro).
Chromebooks have different action keys and some of them are not available on a windows style keyboards sadly you cannot modify the system shotcuts :(
Keyboard shotcuts sometimes do not work especally alt + tab, moving mouse seems to resolve them
Animations do not match touchpad guestures, first you put in the touchpad guestures after that the animation is played like switching workspaces or showing all desktops, supper annoying!
Android apps are a mess. Apps like discord, slack and youtube are all unusable though i need to note this is not spesific to my device this is a mess on all Chrome OS devices.

To get into the linux shell:


ctrl + alt + t in browser
