As described above with a hardware accelerated Gnome, Unity or XFCE desktop? I'm currently limping on with crouton for the time being.
Ideally:
- A backed up Chromebook OS replaced.
- OR an external SD Card / fast USB 3.0 drive booted into at startup.
Best Wishes, Spearthistle.

Happy days @OwenHines.
There's a ChrUbuntu thread on Reddit that has a modified ChrUbuntu script compatible with the HP Chromebook 14 G3 Tegra K1 nyan_blaze ARM architecture (I cannot post the original link here because I don't have at least 10 reputation points for 2 links).
The script had a couple of minor bugs, which I've fixed, available here, and I also added 'username', 'password' and 'hostname' variables to the top of the script so that you don't have to change these details after installation.
If you read the script, it says that you have to run (slightly elaborated): sudo parted --script /dev/<device_id> "mktable gpt" where <device_id> is either sd[a|b|c|d] (usb stick) or mmcblk1 (sd card)
first, to create an empty gpt partition table (because Chrome OS shell no longer has the parted command).
After that execute sudo bash chrubuntu-tegra-HP-Chromebook-14-Tegra-K1.sh default latest /dev/<device_id> which will install Trusty Tahr 14.04.5 LTS and the Unity Desktop
I installed to a fast 32GB+ USB 3.0 pen drive and performance is good.
After the script finishes press enter to reboot and then Ctrl-U when on the Chromebook Boot Screen.
I tested various webgl benchmarks. ran at 60fps
Don't upgrade to 16.04 because lots of things break and Tegra K1 GPU acceleration is only supported by this 14.04 install.
The other scripts, "backup" and "sign" are for compressed backups and for restoration. You have to sign the restored kernel whilst in the Chrome OS shell.
Best Wishes, @spearthistle.
