Adding a GPU to my server, for transcoding peertube app, has added a desktop GUI login on reboot

[AartJansen]

This lovely additional feature also introduces power saving, and my server goes to sleep, if I don't switch to a console. ie CTRL+ALT+F5
I want to remove the desktop login, but retain the GPU driver.
Google led me to run
apt-get remove ubuntu-desktop
this reports ubuntu-desktop isn't installed.
Another result suggested
apt-get remove x11*
However that looks like it will remove a hell of a lot, including possibly the nvidia driver
One thing it lists is gdm3*

Would
apt-get remove gdm3* prevent a desktop GUI login on reboot ? Is this a good idea, is it the best solution ?
Anyone else had this issue by adding a GPU to their server ?

You can edit GRUB to permanently boot into console mode, only: https://www.baeldung.com/linux/boot-linux-command-line-mode

This is not ideal, generally installing anything manually on the side of Cloudron will likely break in the future, as we can't validate platform updates in such unknown situations and thus we can't realistically support you then.

Adding GPU support does not require installing a desktop in the first place. Depending on your card, maybe installing the vendor driver only. And then the app package needs to support this, like the emby package does.

One must be more discerning and careful about installing certain driver packages as some come with GUI tweaking utilities which then pull in an entire desktop environment vs only installing the driver component needed.
