USB to VGA adapters that work with Linux??

I'm needing a 3rd monitor to have more apps up and running at the same time.
Since I'm only dealing with desktop apps and not gaming a USB solution would be ideal.
So far I have not found one that had linux support. All appear to be a bit sketchy on linux.

Anyone use one of these adapters on Linux??

Thanks
 
No, but I've used several in a work environment on Windows. The place I work has a few people using various ones for multi-screen displays for business monitoring applications. So we have a few different brands in use. The HP one that I've purchased a couple of times doesn't seem to have a Linux driver, but this one from Unitek does.

The lag with the USB monitors drive me nuts. I just can't use them.
 
The USB adapters are a pretty sketchy solution, can't you pick up a nice cheap second hand GT610 or something?
 
The Matrox DualHead or TripleHead might work for you. It’s not USB - it connects to the system’s video out. The device tells the computer that you’re running an ultra wide display (3840 x 1080 for example) and then separates the video signal to each display connected. Since it’s a hardware solution it is as fast as your GPU (and even integrated graphics would be faster than USB) and should be OS agnostic for your Linux needs without the overall glitchyness of the USB devices.

Edit: looks like it needs to be set up under Windows, but after that it is good with Linux https://ubuntuforums.org/showthread.php?t=1744124

Been doing some digging and there is Ubuntu support for USB-VGA adapters based on the DisplayLink chip. I expect some latency but this is 2D desktop stuff; I just need to montor some apps that track phone system status, etc. The DisplayLink sites mentions support only for certain versions of their chips though. A lot of the ones you find at a reasonable price (less than 50 bux) are unsupported versions. :(

I would rather go this direction instead of getting in the middle of buying an expensive video card and HOPE there is good support for it on Linux.

A GT610 or equivalent is probably worth not much more than a decent USB > VGA adapter. I ran a GT610 for quite some time when I set up my first Linux PC, they're a little cracker of a card! I used to game on it using a 1366 x 768 monitor just fine.

How many monitors were you running at once on your system? I'm actually running a GT210 on my work system and it does well on dual DVI monitors. I've never done multiple video cards on Linux. It never occurred to me because I found the support for a single video card so spotty at times. Will this work for a quad display setup?

In the end my GT210 2GB was running two 1080p displays and did so faultlessly, it was a great card for $40.00!

I'm already running 2 on the video card; need add a 3rd maybe a 4th. This would be easy by running 2 video cards if the support was there.

I have run two Nvidia cards in my Linux PC no worries in the past, although admittedly I didn't run any monitors off the second card, I just used it for CUDA acceleration and it was paired with a GT610 2GB.

Bear in mind that even if you run a USB adapter, you're still running two graphics chips. The difference is drivers are better supported using the Nvidia card.
