Ahoy - I am as green as green can be when it comes to using any Linux OS, so please forgive any ignorance, I am learning as I go, I only installed this yesterday and I have zero Linux experience.
I use a Samsung smart TV as my external monitor and my computer is a Lenovo Legion y540 gaming laptop with 16gig of ram - its about 4 years old at this point i think. It still plays the games I like to play with no issues at all and when I was using windows, my tv worked great as my monitor for all of my games fps' and otherwise - sure its not like top of the line gaming specs, but it works for me ya know.
Now that I have swapped over to linux mint, i am having very very very noticeable lag on the external monitor. My mouse cursor is delayed by like a quarter of a second, and almost by a second when I boot up a game.
I am using the most current open source driver for my graphic card, because if i use the recommended NVIDIA driver, the monitor wont recognize at all.
I have a GeForce GTX 1650 Mobile in this laptop.
I've tired looking into this last night but was stumped, so any guidance from you all would be wonderful.
Thank you in advance
Also please let me know what other info I can provide (and how I can provide it - again - super new here on Linux Mint)
Edit: I resolved the issue by using Pop!_os instead of Mint, I assume it is a driver issue because Nvidia - however there are several suggestions I did not try below that may have worked as well - but I think Pop!_os will be much more on brand for me. Thanks for the help all!
Using the open source driver with Nvidia is a bad idea, your card is locked at the minimum clock speed and it's general quality is not comparable to the proprietary driver (this is purely because of Nvidia's hostility to open source, not due to any inabilities of the developers of Nouvea.)
I'm gonna assume you are using the default desktop environment of Mint which is Cinnamon. Have you tried booting a different DE, or even better, a different distribution with something like Gnome or KDE to see if the issue persists?
I will be moving away from NVIDIA with my next computer for sure, thanks for that info.
I am using Cinnamon, yes. I have not tried anything beyond this basic install of Mint, I am still very much learning.
I would try flashing an Ubuntu (or Kubuntu for KDE) or PopOS iso and booting that to try, they both include the proprietary Nvidia driver. This might be a Cinnamon issue or a Mint issue, trying a different distro helps you narrow down the possible cause.
This is probably a pretty unpopular opinion but I would never recommend anything but Gnome or KDE to a new Linux user. Those projects just have so much more development focus on them then all the smaller ones, it just makes sense to default to them for maximum ease of use and compatibility.
Pop!_os did the trick! Monitor works perfectly and I really love the look of pop better than mint already. Thank you so much.
This is a really fun journey and I wish I started it sooner.
No better time than the present!
Glad to hear it! Enjoy your Linux journey!
Okay great - thank you so much, I will give POP!_os a whirl, that was another I considered, i will get on that this evening! I truly appreciate the help!
