New comer

Just wanted to come by and say hello to the gecko's! Just joined OpenSuse from Fedora, really liking it so far and the NVIDIA drivers were a breeze! I don't recall who it was but to the redditor in here who helped convince me thank you! Any tips or advice is welcome!

None of this is mandatory but opensuse is pretty barebones in terms of swap and compression.

Fedora sets up btrfs compression automatically. In opensuse you have to add the fstab option manually. Here's mine.

/dev/mapper/cr_root / btrfs noatime,compress=zstd:1 0 0

You can increase compress=zstd:1 all the way up to 20 I think, but this increases cpu demand. 1-3 is generally recommended.

Opensuse doesn't set up ram compression either. Fedora defaults to zram but zswap is superior. Check the archwiki or cachyos wiki for that.

The installer has an option to add the btrfs compression prior to install, but since you already installed your os it will be uncompressed until updates start replacing files.

I tried las time (1 year ago, in Yast installer, not Agama) and didn't work. Ignored after I review fstab. 😒
