My new workstation is “finished”; I’ve been using it for client work and all seems well. I meant to post interim updates on its progress along with some photos, but got carried away with the build. No doubt I’ll get some photos on here soon.
One minor issue which I resolved (at least for now) last night was annoying pauses in GNU/Linux (Ubuntu), which I use as my main operating system. These roughly second-long pauses in which my mouse input wasn’t actioned seemed to occur particularly often when doing things like switching tabs in Thunderbird’s settings dialogue boxes amongst other things.
They hadn’t always been present, and I was pretty sure they were because of some adjustments I had made to operating system settings on account of using a SSD (solid-state drive), which were intended to increase long-term performance and wear levels. I’d followed most of the tips from these pages:
- New to SSDs?
- Four Tweaks for Using Linux with Solid State Drives
- Geek Sheet: A Tweaker’s Guide to Solid State Drives (SSDs) and Linux
- Linux Filesystems for Modern SSDs and TRIM Support
Following the advice given, I’d enabled TRIM support for my ext4 partition by editing my fstab file. However, after making that and other changes, a process of elimination showed that it was this adding of the ‘discard’ option that had introduced the annoying pauses.
I’m now running without ‘discard’ (TRIM) enabled on my Crucial RealSSD C300. Hopefully the drive will “recover” well enough without TRIM. I’ll also try re-enabling ‘discard’ every time a new kernel is installed to see if this issue gets sorted.
