maybe libgl1-mesa removed? see with package manager if libgl1-mesa-dri and libgl1-mesa-glx still installed or you can try reconfigure xserver-xorg sudo apt-get update sudo apt-get install --reinstall xserver-xorg-video-intel xserver-xorg-core libgl1-mesa-dri libgl1-mesa-glx sudo dpkg-reconfigure xse...

You are using software rendering
Intel hardware rendering use Mesa DRI
Do you using video driver PPA

check file : /etc/environment
if you are see line : delete it. Save and reboot

No problem for me ( LM 18.3 MATE with open source intel driver )
Maybe just affected user with proprietary driver installed

Good for you
For me just one workspace .
My litle brain isn't built to split its attention in too many workspace

fglrx ( ATI proprietary driver is depracated ). Sure you can install fglrx in LM 17 but limited up to kernel 4.2 and X.Org 1.17 . Latest kernel in Mint 17.3 is 4.4.
Maybe this solution will help : https://cubethethird.wordpress.com/2016 ... on-ubuntu/

assuming that atom box have working internet connection and didn't have nvidia proprietary driver installed. Launch terminal:
Reboot

LM cannot upgrade directly from 17.3 to 18.3 directly. There is tutorial from clem : https://community.linuxmint.com/tutorial/view/2
For me usually back up my data and do fresh install ( but cannot be done remotely )

No idea
You are using a correct graphic driver.
Maybe reinstalling xorg

Intel kabylake processor need newer kernel.
You can try using upstream kernels archive (beware : not recommended , can crash your system ) https://wiki.ubuntu.com/Kernel/MainlineBuilds
I think installing LM18.3 will do safer job. Try in live environment first

From my experience, swap LM hard disk to another mobo/PC not a problem if you are using open source driver. Maybe launch driver manager will help.
What of output :

Try update to latest MESA and Kernel ( update manager level 4 & 5).
The amount of RAM not showing in your post. AMD E-450 is pretty slow processor. Maybe MATE or XFCE will do
