I have ubuntu 18.04 installed alongside windows 10. This is my pc: https://www.notebookcheck.net/Asus-ROG-GL503VD-DB74-7700HQ-GTX-1050-Laptop-Review.259452.0.html

I have installed proprietary driver for nvida vga (GeForce GTX 1050/PCIe/SSE2).

vainfo output is as follows:

libva info: VA-API version 1.1.0
libva info: va_getDriverName() returns 0
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/nvidia_drv_video.so

I just cannot play videos (.mkv, .mp4, etc) smoothly, video runs choppy. In windows runs smoothly. In ubuntu I play with videos and vlc as players with the same result. Interestingly videos in youtube runs smoother than in vlc or videos.

I have checked some previous questions (Choppy video under Ubuntu but not Windows)

How do I enable hardware accelerated video in VLC with Intel HD 4000 GPU?

however, some are outdated. Thanks for any guide on this.

  • Edit your question and show me free -h and sysctl vm.swappiness and dpkg -l *nvidia* | grep ii and sudo dmidecode -s bios-version. – heynnema Mar 29 '20 at 15:21
  • @heynnema added free -h and sysctl vm.swappiness and dpkg -l nvidia | grep ii and sudo dmidecode -s bios-version as you requested. – Nicolas Molano Mar 29 '20 at 15:28
  • Your BIOS is good. Your mem/swap looks good. If you stop all apps besides Videos/VLC, does it make any difference? You might try a newer Nvidia driver 440.64 available at geforce.com/drivers – heynnema Mar 29 '20 at 15:45

One way I got rid of screen tearing on my laptop with Nvidia discrete graphics was switching to Gnome Wayland

You can do so by clicking the gear icon and choosing Wayland when logging into your account.

I utimately ended up disabling Nvidia graphics in the BIOS and switching back to Gnome xorg due to the lack of some features in Wayland and the fact that I didn't plan on using the laptop for gaming.

I didn't have any screen tearing issues on either Wayland or xorg when using Intel's integrated graphics.

If you want to use discrete graphics in unbutu, you should give Wayland a try.
