Trying to get a usb sound card to work, I followed some of the instructions on https://help.ubuntu.com/community/Medibuntu .
When I rebooted the pc, the cinnamon desktop had decided to take a holiday/vacation. It looks like it's booting into Gnome instead . Cinnamon is set as the default desktop. I've tried a complete re-install of cinnamon also .
I've read that maybe re-installing the Nvidia driver may help .Though when I shut down my desk top I'm in ,via tterminal,in order to install the drivers, via the command prompt, I get a fuzzy looking screen with flashing squares (A good analogy would be a classic 80's Atari computer game. The fuzzy looking screen popping up when I shut down etc has been a feature since I originally installed the proprietary Nvidia drivers (but at least it fixed the blank screen on resume).
So I've got my version of linux mint into a Global meltdown situation ,i.e. a positive feedback loop. Where one fault in the system, (For example - Increase in CO2 in the context of climate change) my sound card of my PC, as led to another fault ,the non loading cinnamon desktop. Which in turn has accentuated the fault of a flashy screen command prompt.
So my pc system is screwed
luckily in this context ,should the worse case scenario happen and my machine goes into runaway melt down,and all the signs are there that it has begun ,at least I can perform a full system re-install . But I will then rename linux mint to linux Venus . Just kidding 
, if it wasn't for the graphics card and sound card then I would feel like I have a mint system . Could I use the live cd to boot into a command prompt and try to re-install the graphics card?.
Or could there be another issue why my nicely configured cinnamon is refusing to show it's attractive features ?.
