Hi,
I have recently tested the Live-CD of Trisquel and was really impressed of the beautiful appearance and how nearly everything looked well configured. I also share the ideas of the free software movement completely as I have experienced the benefits of free software by myself. That's why why I am planning to free all of my hardware of proprietary sofware step by step. For that reason the best idea is first of all to USE a completely free operating system. At the moment I have Lubuntu (and Windows 7...) installed on the SSD of my laptop which I want to move to a conventional HDD and install Trisquel 6 instead on the SSD.
I would like to know if anyone has experiences with Trisquel on a SSD and if TRIM is supported by Trisquel 6? The Linux-kernel supports the TRIM-command through an ATA-command since version 2.6.33 but I am not sure if the libre kernel also supports it.

Thank you in advance for your help.

PS: This is my first post here :)

I'm pretty sure it does. The main difference between the mainline kernel and linux-libre is the later is missing the non-free parts. There are also some patches applied. None of which would be impacted by this.

Welcome to the forums and to Trisquel!

I agree with Chris.

I am using Trisquel 6.0 with an SSD. A copy of my /etc/fstab is attached as
/tmp/fstab.txt. You will see that the SSD has the options "noatime,discard".
So far as I know, this ensures that the SSD will not be written to unnecessarily. The TRIM function is provided by the "discard" option.
Trisquel works very well with my SSD.

Thank you for your information and for sharing your /etc/fstab-file. As far as I know a better way as the "discard" option (which is called "online discard") is "batched discard" because online discard "slows operation considerably; there's also been some claims that excessive trimming can, itself, shorten drive life." (http://lwn.net/Articles/417809/)

To use batched discard, you need to create a file /etc/cron.weekly/batched_discard (weekly) /etc/cron.daily/batched_discard (daily) respectively with this text:

#!/bin/sh
LOG=/var/log/batched_discard.log
echo "*** $(date -R) ***" >> $LOG
fstrim -v / >> $LOG
fstrim -v /home >> $LOG

(This example presumes that you have a root and home partition; you may need to modify it to your needs.)

Than you need to make it executable:

sudo chmod 755 /etc/cron.weekly/batched_discard

TRIM works smoothly in Trisquel 6.

Tested with Crucial M4 and M500 SSDs.

You can check by: sudo hdparm -I /dev/sda | grep TRIM
You will see: Data Set Management TRIM supported
