Background: I have been using Ubuntu on a desktop for 2 years now and it worked well. I thought I'd try running it on my Dell Inspiron 7373 laptop.

Problem: Xorg crashes a lot when I try to play a video (almost 100%), be it web streaming or local file, most of the time right after going into full screen mode.

Setup:

  • Intel® UHD Graphics 620
  • Dual monitors

Driver (lshw -c video):

  *-display                 
   description: VGA compatible controller

What I have tried:

1) configure 20-intel.conf

Section "Device"
 Identifier "Card0"
 Driver "Intel"
 Option "AccelMethod" "uxa"
EndSection

2) sudo apt update & upgrade

3) Disable/enable hardware acceleration in Chrome

If there are any other logs that will help, please let me know Any help will be appreciated! Thank you!

I'm not sure if it's the best fix but hope it helps someone.

The crashes stopped coming after I made these 2 changes:

  1. uninstall easystroke
  2. change /usr/share/X11/xorg.conf.d/20-intel.conf to

    Section "Device"
      Identifier  "Intel Graphics"
      Driver "Intel"
      Option "AccelMethod" "sna"
    EndSection
