Laggy graphics in Gnome Desktop on Ubuntu 18.04

Question

Right now I am running the release version of Ubuntu 18.04 but for some reason gnome desktop seems to remain ever so lagging and unusable. It is so bad that even the scrolling lags.

This thing fortunately/Unfortunately (depends on how you see it) is unique to gnome desktop so other desktops cough Budgie cough remain un-laagy and thankfully usable. However is there any way to get rid of this frustrating lag in Gnome.

My PC Specs:

• Intel dh61bf motherboard

• gt710 (gk208) GPU

• Intel core i3 processor.

• 500 GB HDD of which 55.5 GB to Ubuntu and rest to Windows

Solution

You are not using the "non-proprietary" driver. You are using the nVidia driver 390.48. In the terminal type:

sudo prime-select intel

Then reboot and the Intel iGPU will be used and hopefully performance will be better.

Which core i3 processor? Are you using the iGPU on it? Are you using the nVidia GPU, if so the Nouveau or nVidia proprietary drivers? If using the nVidia GPU I'd suggest using the Intel iGPU for comparison.

Can you run this command in the terminal and copy the results into your question? DRI_PRIME=1 glxinfo | grep "OpenGL"

The thing is I was using noveau before but switched to nvidia after you commented on the question. There is an improvement in performance but it is really marginal
