Yes. You can see and reply to SMS text messages, Slack channel messages, and WhatsApp messages. Maybe more, but those are the ones I use. It also does a lot more than just that, e.g. using your phone as a touchpad to interact with your computer, streaming media from your phone, transfer files, et al. Here's the website for the project. Also note you could just install this one thing in your regular desktop without installing all of KDE, but I haven't personally tried that.
If you are liking shell scripting in bash, you might also want to check out zsh and especially om-my-zsh! I spend a fair bit of time in the terminal and after adopting zsh I would never go back because of all the productivity tools available in it (plus it's pretty).
In linux you can use cpufreq to alter CPU governors and have a fast or conservative cpu.
Check cpufreq-info and cpufreq-set
You could write a daemon to use class-leds to alter those leds, if they are available, in order to maintain the same windows behaviour.
An old T30 is not going to run Pop OS. It may run Debian with a lightweight window manager (openbox, fluxbox, etc.). Might try Anti-X which is Debian based with multiple lightweight window manager desktops available.
It is very easy to run a newer kernel if you install the UKUU program. Select it of a menu and press install. It prompts you when a new one comes out. Just install one > 4.17 as it has new energy saving properties. You don't have to keep upgrading afterwards.
Thanks for your reply, that's very helpful.
> For non-thunderbolt docks, in case you wanna save a bit of money or got the AMD version, you are a bit more limited, will probably need to get one with display port (HDMI seems to be more limited) and usb 2.0, like this:https://www.amazon.com/dp/B0746NKVBN/
I do have the AMD version of the E14 gen 2, I didn't know that made a difference - thanks for pointing that out! So you're saying it's hard to find a docking station with HDMI that works with AMD E14s?
