Ubuntu server to run Remmina only

Hi,

My Linux knowledge is not great and I am configuring computers that should be used to connect to a remote server via Remmina only.

The goal is to enable the users to connect to the remote server and to restrict their interaction with the local OS.

I installed Ubuntu server and did the following configurations :

 undefined

    
LVM partition, encrypted

sudo apt-get install remmina

sudo adduser *username*

Autologin of *username*
    sudo nano /etc/systemd/logind.conf
        NAutoVTs=6
        ReserveVT=7
    sudo mkdir /etc/systemd/system/getty@tty1.service.d/
    sudo nano /etc/systemd/system/getty@tty1.service.d/override.conf
        [Service]
        ExecStart=
        ExecStart=-/sbin/agetty --noissue --autologin *username* %I $TERM
        Type=idle

Install xinit
    sudo apt install xinit
    sudo nano /etc/X11/xinit/xinitrc
        setxkbmap -layout en
        exec remmina
        Comment ". /etc/X11/Xsession"

Auto startx
    nano .profile
    Add
        #StartX Autostart
        if [[ -z "$DISPLAY" ]] && [[ $(tty) = /dev/tty1 ]]; then
        . startx
        logout
        fi

Hide cmdlines
    sudo nano /etc/default/grub
        Edit line
            GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
    sudo update-grub
    sudo nano /etc/default/grub.d/50-curtin-settings.cfg
        Add line
            GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
    sudo update-grub

It is working almost as it needs to but as I’m not experienced I’m wondering if my configuration is a good way of achieving my goal. Could I improve something ?

Ideally I want to restrict the users ability to change the configurations of Remmina but I didn’t find a good solution yet.

It is a bit slow to boot. Maybe some useless services are being started and I could disable them ? How could I know what services are not needed by Remmina and could be disabled ? Or would it be easier for me to use a minimal distribution like Arch ? Could I still apply my configuration steps or am I going to need to change everything ?

Thanks in advance for any insight.
