Unable to use Ubuntu

I downloaded LP's Ubuntu OS version here .

It starts at the bootup screen but it seems that whichever option I choose, it always ends up booting without installing Ubuntu. It then opens what looks to be the desktop with no menu bar. Whatever I try to do to bring up a menu bar fails - there is no right click, and no response to any keyboard action.

I am stuck where to begin fixing / how to install a working Ubuntu OS on the LP. Thanks!!!

Hi,

I can give you my experience, maybe it helps.
First I installed also the LP linux image, had no problems doing so. But the distro is full of broken packages, e.g. if I wanted to install additional Python libraries it always fails installation due to broken dependent packages, after a while I gave up :roll: ), But everything else worked!
I overcome it by installing OpenSuse Leap or Ubuntu 18, just the standard distribution, all things work fine :D

Just one thing if you install Linux (I just think it does not happen in the LP distro, but maybe I forgot...) in reference to your statement: "...looks to be the desktop with no menu bar. Whatever I try to do to bring up a menu bar fails - there is no right click, and no response to any keyboard action."
Per default the Linux OS uses on LP as primary screen the DSP-1 (MIPI-DSI connection), but I assume you only use your hdmi connection (as most will do). So try to get the mouse cursor visible on your hdmi connected screen, right click and open a new terminal. Then run "xrandr -q" and you should see the "available" displays, the DSP-1 for MIPI-DSI (even if none connected) and your HDMI screen (in my case it was called HDMI-2). To activate HDMI screen use command "xrandr --output HDMI-2 --auto" (in my case it is HDMI-2) and deactivate DSP with "xrandr --output DSP-1 --off". Then you should see your desired linux desktop.
Hope it helps!

or simply disable DSI output via kernel/boot parameter ;-)
