Does Linux/Ubuntu have Trim support or something similar?

[Red Hawk]

I don't use my laptop for gaming since I got my desktop, so I was thinking about turning it into an Ubuntu machine. Before I do, I need to know if Ubuntu supports Trim or a similar data garbage collection service. So, does it?

fstrim - v mountpoint

That's all you need.

There is also wiper.sh, from the author of hdparm, that seems to work with more filesystems than does fstrim.

Also, for filesystems that support discard, you can mount the volume with the "discard" mount option and TRIM commands will be sent automatically.
