The Endless OS installer worked flawlessly on my Thinkpad X220. Endless OS was installed along side Windows 10 in a UEFI setup on a GPT formatted hard drive. It was very nicely done and much appreciated. All the special Thinkpad features were recognized and are being utilized by the system. It makes a great first impression when everything just works.
In using Endless OS I have come across a number of what I believe are bugs. I have not thoroughly researched them in the forum, but if already mentioned I will simply add them as a me too.
When I go to the support section of the Endless OS website, there is orange text āSigninā, which I assume is where one logs into the community (maybe not). When clicked a login window appears. Entering my credentials and clicking submit does nothing except just freezing the site making it necessary to reload. That is using the built in browser in Endless.
Battery life is ~25% less than on Windows. Linux generally does poorer than Windows, but can be brought mostly up to par with Windows using something like ātlpā. I am just assuming that is not installed on Endless nor does it appear as an option to install. Maximizing battery life/run time is a good thing.
A couple things might well be up stream issues. The Weather application often reports an internet connection is needed, when in fact the internet connection is working fine. Also the Weather application does not honor the system preferences for units. It just reports metric units. Shotwell (Photos) still lists Picasso Web Albums for publish. I do not know if that automatically redirects to Google Photos or not, but Picasso Web Albums are a thing of the past.
When adding āweb sitesā a check mark is placed by what you wish too add, but once added it is not possible to click the check mark and remove the site. Along the same lines there does not seem to be an obvious way to remove an application. Applications can be removed from the desktop, which perhaps hides them, but once installed it appears you are just stuck with them.
Special keys (brightness, sound, etc) stop working at times. They can be reactivated by going to the keyboard shortcuts preference pane to change them at which point Endless pops up a messages saying they can not be changed and after doing that they start working until at some point they once again just stop working.
None of these effect the overall quality of the system, but they are distractions. Overall the system is pretty darn fine.
