Hi George! This has been going on for a while now,At lest the last two destros.
DO NOT install the 390's!!
Not unless you have a newer card than my GTX 670.

Use the 340's or 340.107. (Same thing) I know the 390 "may" show up in device manger as "recommended", but they don't work with my GTX 670. They completely screw the pooch!!

As I can't say for certain as I don't have your video card but for me the 340' work quite well and engender no problems for my system.

This is where that backing up I'm always harping on.can REALLY really help guy out!

you MUST make a back up BEFORE you have the 390's installed on your system.
Once you have your a good back up try installing the 340's.

If they give you trouble and there is as yet no reason to think they will give you trouble then revert by way of your new back up.

Doing things in this way encounters almost zero risk to your system.

I have tried the the "recommend" 390 4 times. had to do a complete re-install from backup each time.

Device Manger chokes every-time! it won't let me go back to the 340 or the Xserver.xorg. 390 will only give me 1920X1080 while the older drivers "340"
give me 4096X 2160.

once the 390 are installed there is only one way forward for me, that's by way of my backup. or if I didn't have one a complete reinstall.

I feel remiss in not having alerted you to this pit fall. But so far I'm the only one I've seen with this problem.

It seems that somewhere along the line Nvidia or mint dropped the ball in recommending a drive to me that is bound to fail.

Good luck let us know. If you don't have a back up SAY SO!!
One of our big guys may be able get you past this without a restore or a reinstall.

Don't blame you! this is not you. Go slow seek help whenever your uncertain. be patient with you. stay in touch

Just read your post again!!
D.M. doesn't offer you the 340 drivers?

Then do your back up and try the 390's. I don't think there is anything WRONG with them, they just aren't suited to my card.

Mint will install the Xserver xorg drivers (Linux drivers rather than Nvidia drivers.) by default while installing herself unless you tell it otherwise. (I always install Nvidia at install.)

The 390' may be fine with your card...I just don't know. do your Back up and start experimenting.

Do you know how to do a back up? Don't be shy it's not at all hard ...be glad to talk you though it! ":O}

A second back up drive is your emancipation form the tyranny of ones own mistakes!

A second SSD will provide a very fast...as in actually fun to watch... back ups and restores. but if your feeling on the conservative side large spinners can now be had for peanuts...andf they work fine along sidr your SSD.
but your back up time will be less than trilling.

As for the 390 drives...I'm not at all sure they do suck.
It's just as likely that they work just fine...on THE RIGHT CARD.

One of which you and I do not possess.

I've been kinda assuming that we were just miss-Recommend the 390's.. The 340's work great for me. Are you offered a 340 driver in Device manger?

sorry I've only used it when it popped up automatically.

You can download Banshee from the mint Software manager, I think it "mostly" does the same thing.

Been there done that.
all I can suggest is that you just keep looking until you find something you can use.

Not sure.. I don't have any video's I just keep games around. The rest is all net flicks and Hulu.

When I first came to the park
i borrowed a mess of them movie videos. But that was Mint 16 or 17.
I know that It worked for me back them. but even back then I almost never used it. I use my PS3 or 4 to watch movies.

Blue-ray drives (Play only no burning) are pretty cheep these days and plug straight into your TV. Seems a better solution than reverting to 17.

You just need a "Player" not a burner to watch directly from played to your TV, no computer needed. HDMI is required for most TV's.

You might start looking here https://www.ebay.com/b/Blu-ray-Players/175711

Since 4K has come out, prices on just blue ray have really come down.

Check to see if your trying to play BlueRay on non blueray drive.

"the damn thing because its remote doesn't perform every function it should.) But I have to wait until the thing dies to justify the expense."

Sounds like you bought a Pinto!! Sorry dude they never die when you want them too!

I don't understand why you are not getting the 340 as a choice!

Here's what device manger offers me.

Boo..
I followed your easy to follow instructions in Mint 19.1.
Everything seems good. I'll do a fresh back up and see what drivers I may be able to use besides the 340's which as we can see are quite old now. Thank you Boo! ":O}
