    Hi, until yet, I am happy... but... how can I be sure, that I got the best gaphic that is available (for my system)?

    Yes, after my first "real boot" from the sdd-ubuntu-installation, the system did download some updates. So the current status is "no new updates available".

    New PC: 20.04 LTS does not load from Live-USB-stick - many error messages

    Until yet... it feels okay... but to be honest... I did not start installing the software I need for my daily work... just for the case, that I need to reinstall Ubuntu again.... because "dmesg" delivers some errors... but I have no idea yet, if they are "critical" and how to handle them. Its a...

    Hi, I am sorry, I can't enter more than I have already written... it was just a short information, as far as I can remember after the installation of Ubuntu, when I had to do the reboot... it was just that information-text, that three files were damaged... no more information what files...

    New PC: 20.04 LTS does not load from Live-USB-stick - many error messages

    Hi, yes, the problem was the boot order... Win10 and Ubuntu share the same SSD... but for some reason, the uefi boot order was "windows" >> "ubuntu"... so I just had to switch it... now Grub is the first choice and so I have the choice yet... Thx. :) But I have two "bonus" questions...
