One of my favorite bits of software is Xpra [0], "screen for X". You'd run it and it would start another X server (start apps in it with `DISPLAY=:1 xterm` or whatever), and you would "attach" it to your running X server with `xpra attach`. You can attach to e.g. `ssh://hostname/:1`, so I ran a firefox instance on a homelab server and attached to it from my laptop and my desktop to not have to bother keeping... - Source: Hacker News / 11 months ago

I’ve used Xpra in the past to connect to a remote system for GUI stuff, but I almost exclusively use ssh because most of the time I don’t need to run a remote windowing system. Source: about 1 year ago

To add to this if you need to access graphical applications of an entire desktop environment you can use Xpra or MOONLIGHT (I suggest the second one if you want to game on the remote desktop or need very low latency in general), you can use both of these through a ssh tunnel (you need to enable this and X forwarding in the config) so if you setup and allow access to ssh correctly you can also use these without too...

You might be able to do the screen recording today using Wayland ports, or nested display servers a la Xpra. https://xpra.org. - Source: Hacker News / over 1 year ago

I always wanted more feedback, so that even in the mechanical disks and lots of fans era my desktop has always shown more data with GKrellM plus some of its plugins, namely multiping to show the status of my NAS and router, and bubblefishymon for a funny but very effective and immediate way to show that system load is growing suspiciously before fans start screaming. http://gkrellm.srcbox.net/ As for servers,... - Source: Hacker News / 6 months ago

Possibly not old enough to be included in that list, but my oldest piece of desktop software I always run on my main machine is GKrellm with BubbleFishyMon as system load monitor. http://gkrellm.srcbox.net/. - Source: Hacker News / 11 months ago

That doesn't always give correct readings depending on the chipset on your MB. There was a driver missing for like IT87 that returned voltage and temps to psensor. I finally gave up trying. gkrellm can monitor cpu, and many other things. You can add what you want. Source: almost 2 years ago

Gkrellm was not really part of GNOME or KDE, but it was one of the best tools and there was recently talk about porting it to modern GTK releases. Source: about 2 years ago

OP: Another option is GKrellM. It has not been updated in a couple of years, but it still appears in Software Manager. It should work with the current versions of LM. I used it for a while on LM 17.2 because I wanted a desktop system monitor and I was too lazy to mess with Conky - I stopped using it when I moved to LM 18.1 and eliminated eye candy.
