OK here's the reality and I'm speaking from personal experience as I have a desktop with that same POS integrated graphics adapter.
Linux Mint 18.0 Xfce is your best and possibly the only hope for that POS integrated graphics adapter and you will need to install the proprietary Nvidia...
I haven't found a keyboard yet that wouldn't work on Linux.
My keyboards have always been the standard oem wired keyboards.
A keyboard is pretty much a keyboard and if it's wired ps2 or usb I don't see any reason it wouldn't work.
The one way to know for certain is to try it and see.
You don't mention what kind of graphics your computer is running integrated graphics or discrete graphics card and what it is.
A weak graphics adapter can cause Ubuntu 18.04 to load on the processor which can slow things down.
I also agree with TechnoJunky that an SSD will speed things up a...
If you decide to use BleachBit make certain that you understand each feature and exactly what each feature cleans / removes before enabling it.
BleachBit installs with no default safe settings and if used haphazardly it is almost certain to remove more than is needed and will break a Linux...
I agree new Linux releases do seem to be getting bigger require more resources to run which is why I'm leaning towards the small footprint low resource Linux Distros.
I will say that Mark Greaves has done an excellent job with Peppermint Linux as it does work well and still uses less resources...
I thought Pepermint was Ubuntu based with bits and pieces of Lubuntu and Xfce user interface although I may be wrong about that.
I've used Peppermint 7 and Peppermint 8 for awhile but ain't real fond of Peppermint 9 or Peppermint 10 ...
I believe my issues I have with Solus are due to the age of my desktops.
I have run into this problem before may just be lack driver support although uncertain.
You should also have a look at MX-Linux as it comes loaded with software.
It is recommended to stick with software from the repos as...
No luck with Solus on my old 2007 outdated desktop.
I was unable to even be able to run it as Live Distro from usb.
I gave up on Solus as it ain't worth the headache.
I did install and am running antiX-19.b2_x64-full Marielle Franco 13 July 2019 base: Debian GNU/Linux 10 (buster).
It is a...
As for antiX Linux you just have to download it and experience the antiX magic.
I use old outdated desktops so antiX Linux with its small footprint and low resource requirement
has worked for the most OOTB.
Antix isn't for the novice although its learning curve is minimal and easy to overcome...
MX-Linux is pretty much install and use OOTB or has been on my old outdated desktops.
I've never tried Solus although it looks interesting.
