The next time something like this happens, log in with a different user account. Not root--just a regular, normal user. Go ahead and create another user right now if you don't already have one. Make its rights and privileges exactly the same as yours; make sure it's allowed to access all the same devices, networks, whatever, that you can. When something crazy happens, instead of trying it as root try it as this other, regular user. Does it work? If so, there's SOMETHING garbled/mangled/corrupted/screwed up in your $HOME. This is a great way to attack a problem because it'll tell you straight away if the problem ONLY exists for your usual account. Then you can start troubleshooting--either way.

I wish there was a method to go into XF86config or some sort of means to do the same autoprobing for hardware that the installer does when you first install the system, but i could not find any such app to do that job. also, Ubuntu seems to have done away with console config of X these days, making the problem even harder to fix.
I really don't know. I haven't had to do any fiddling with any of that in...10 years? Maybe 15. I can't remember right now, but a long time at any rate.

Moody, if the app/game you want to use isn't in Synaptic or any other repo, you will end up doing things the hard way. and often spend hours trying to make it work in the distro you use.
No, Nick, I won't/don't. I can, and do, install things outside of Synaptic whenever I feel like it or need it, and I simply do not EVER end up with the problems you're talking about.

perhaps you can live without certain apps or consider it a worthy trade off.
For me I think it's more of an out of sight, out of mind issue. I don't KNOW what's out there for window$ and, therefore, I don't care about, or miss, anything!

but it's a deal breaker when i can't play games others can just because i'm not running Windows.
I understand that. If I were in your shoes, well, I don't know what I'd do. On principle alone I won't use window$ or anything else from micro$oft. So I have no idea what I'd do.

it always feels like i'm imprisoned in Android or Linux, as the things i want to do i cannot do. and for me, that 'freedom' feels like a cage when you have to accept that this app or this game isn't going to work and either play a watered down copy port of it or worse, 'get used to it'. that's just not acceptable. for now i got XP working for those programs. like it or not, i'm not giving them up.
I'm as anti-m$ as you'll ever come across--yet I still recognize that if...ugh...IF...something of theirs works better for you than something else, you should use it. I personally wouldn't, but that's me, not you. The greatest thing of all about Linux is that it's all about choice. Choice in operating system, choice in distribution, choice in user interface, skill level, you name it. So if your choice is to NOT use it, that's okay, too.
