Ubuntu new 4k monitor

[opethdisciple]

The OS seems fine and still very responsive but I find at full screen Firefox is really laggy.

Installed Chrome and things are much better but still not 100% but better.

Still feels slower than it should. I knew getting an Nvidia card with Linux was a bad idea. My best experiences with Linux have all been with AMD cards.

Anyway I enabled the Nvidia proprietary driver in the settings: Nvidia driver metapackage from nvidia-driver-455 (proprietary, tested)

Any ideas why Firefox is so laggy?

Is Ubuntu the best OS for using on a 4k display?

I've made a mistake haven't I buying an Nvidia card for running under linux?

I am now thinking of returning this GTX 1030 and getting a Radeon 550.

Seems someone else had the same problem and tested with a Radeon 550 vs his Titan and found the Radeon much better on Ubuntu.

What annoys me is I KNEW Nvidia on Linux was crap. Never have I had a good experience with Nvidia on Linux. I always end up going AMD.

So do you think I am right about thinking of sending this GTX 1030 back and getting a Radeon 550 instead?

OK, I took out the GTX 1030 and put back my old Radeon 6450 and the performance difference is night and day.

This is a 4k screen though and the Radeon 6450 can only 1920x1080.

So is the case that the GTX 1030 isn't great for Linux or is Ubuntu not able to do 4k?

I think your issue is the nVidia card. I have never used nVidia with Linux, only AMD cards, and I have never had an issue with them.

Don't know about the 4k problem in particular since I'm still at 1080, but I would very much doubt that the Ubuntu Mesa stack would have an issue with that res.

If you still have issues you might want to look at changing your cable:

Yup. With all my AMD cards no issues. With all my Nvidia cards and Linux over the years it has been a horrible experience and I've always ended up giving up and going windows on the Nvidia card.

In the end I have returned the GTX 1030 and bought a RX550. Yet to arrive.

OK, just an update if anyone comes across this thread.

Most definitely buy an AMD GPU if you want to run Linux.

Not 100% sure about 4k for general desktop use. Text is very small an webpages end up with a lot of white space.

If you start watching from about 5.40mins you can see why I say AMD is the way to go on Linux rather than Nvidia.

It just works out of the box. I'm not referring to gaming though as I use my Linux machine as a workstation.

I have only ever had issues with Nvidia GPU's on Linux.
