UBUNTU won't load, purple screen, what should I do?

Question

linux

After installing Ubuntu, I turned off the laptop.
After some time - I turn it on, I see that instead of any system boot, only a purple screen (purple in Ubuntu style). Nothing more.

Yes, when you press F2, the system boots fine, except that it does not show the ubuntu icon. If I do not press F2, then the system does NOT boot.

(Some kind of infinite timer)
How to solve this problem now?

Answer 1

There may be something wrong with the peripherals, which causes a delay at the boot stage when initializing the peripherals.
One could try to change the peripheral cables, but only in the case of a PC.
When starting the OS, press Esc once and then all messages will be displayed on the screen during the initialization of subsystems.
Looks like a known issue.
The workaround is to disable Wayland.
In the terminal:
uncomment the line (remove the # symbol):
#WaylandEnable=false
