I tried to install using the full encryption option after the installation finish. When I reboot it couldn’t find the encrypted drive. The installer works without the encryption option.

Hi, you can install the Nvidia driver by Trando. The Nouveau driver must be blacklisted and installed in the Nvidia drivers found in the Gentoo repositories. For xorg.conf, it must be done from the nvidia-xconfig terminal. On the PC with an OK GTX1070 on an old Nvidia card, I had to set /etc/default/grub. I promised myself a guide, I'm working on CalaroOS cinnamon. Let me know if you've solved it; if necessary, ask gemini or write to me. I assure you the Nvidia drivers work on Gentoo. :-) Let me know, if necessary I'll prepare a guide to put on the desktop and add it here in a file.

This is very nice. FINALLY a Gentoo distro that will get you up and running, quickly and easily. At that point you are able to learn gentoo without going nuts. You still use Gentoo for its purpose , you learn it and its because of a easy to get going distro like CalamaroOS. Instead of installing Gentoo getting frustrated and giving up. This is so simple, this is as easy as installing Debian, Opensuse, Bazzite etc ... It is stable even though its rolling. I was easily able to install steam, brave, clam,qbittorrent, mame, and others. This may be the Gentoo distro you have been waiting for. And none of that annoying "Su-" command to sudo ... Give this a try. I think this one is going to be talked about alot in 2026. This truly is the first Gentoo distribution that anyone can get going on. Really Really Easy and Really good.. Do not fear The Gentoo :)
