If you're not sure how to tell someone how to destructively flash a device, why are you doing it?

Has anyone gotten X performing decently on this yet? Every time I have tried, performance has been meh. Scrolling is jittery/slow. If you compare it to Ubuntu running in crouton (chroot with xephyr), Ubuntu is *much* smoother. I imagine it comes down to some compatibility between the versions of kernel/mali driver/X11, but I'm not sure exactly how to get Arch performing as well as crouton Ubuntu does.

Scrolling has been fine for me on it. Also remember that a chroot install under ChromeOS, mooching off of the ChromeOS display system, drivers, etc, does not equal a full install like what we do.

What about the CrOS setup is so different from a full traditional Linux install? The kernel/X11/mali driver should all work on Arch Linux installed natively. If Ubuntu can perform so well even if it is "mooching" off of Chrome OS, I see no reason why Arch cannot. They're both still Linux, utilizing the same underlying technologies. Just differing versions (with the one in ALARM repos being much less than optimal).

I feel like the problem in Arch would probably be X11. CrOS either uses an older version, or a patched version which performs better with the mali driver.

I also find it difficult to believe that X11 performance when scrolling and dragging is "fine" for you. Maybe you have lower expectations than I, but.. have you tried crouton? It makes the native ALARM install look unbearably slow.

Their display drivers are a custom conglomeration of bits and pieces we cannot use due to version conflicts and a massive stack of custom and heavily interdependent software, thus the graphical performance under Arch is not as good since we are just using the fbdev driver. You're free to actually do some research and try to bring in support.

You can also find difficult to believe whatever you want to. For me, scrolling inside chromium and other windows works quite acceptably well. It may not be as smooth as the CromeOS experience, but it is certainly entirely usable. If it's such a huge problem for you, just stop using Arch. No one here is forcing you.

@kmihelich: I believe what I posted is very similar to what is found inside the news group email from Strata. His instructions were fairly terse for a more beginner perspective. I just thought it might be helpful to try to put the instructions in a more central place than buried in a forum thread? Also thought someone might help flush it out to be more prescriptive. Bad decision?

I successfully installed and booted from the USB 2 port. However, when I now try to switch and install and run from either the USB 3 or SD card slot it doesn't work. Any thoughts?

USB 3 port is NOT supported by the u-boot, period.

From this point forward, use the appropriate location in the forum.

This is no longer a community supported device, and has been officially supported for some time.
