Ubuntu 19.10 was installed from a USB key, and no error was shown in the process.
But when we go on the boot of Dell Precision 5820, the screen remains indefinitely pink with only written Ubuntu .... (and the dots that turn) it never leaves this state.
We try to switch to a terminal with Ctrl + Alt + F7 but it never activates.
For information, we disabled the UEFI boot, tried it in LEGACY, and vice versa, but it's the same in both cases.
Anyone have an idea to fix this problem? Thank you
