I need to run Google Chrome remotely on a virtual machine using SSH. I do not want xforwarding - I want to utilize the GPU available on the vm. When I try running google-chrome I get following error:

[19615:19615:0219/152933.751028:ERROR:browser_main_loop.cc(1512)] Unable to open X display.

I've tried to setting my DISPLAY env value to various values:

export DISPLAY=localhost:0.0
export DISPLAY=127.0.0.1:0.0
export DISPLAY=:0.0

I've also tried replacing 0.0 in abowe examples with different values.

I have ForwardX11 no in /etc/ssh/sshd_config I tried setting up target like this:

systemctl isolate multi-user.target

When I try to run sudo lshw -C display i get folowing output:

   *-display

I've tried to update my gpu drivers by:

wget https://www.nvidia.com/content/DriverDownload-March2009/confirmation.php?url=/tesla/375.66/nvidia-diag-driver-local-repo-rhel7-375.66-1.x86_64.rpm
yum -y install nvidia-diag-driver-local-repo-rhel7-375.66-1.x86_64.rpm

But after that I still see UNCLIMED next to my NVIDIA gpu. Aby ideas?

You can try with Xvfb. it does not require additional hardware.

Install Xvfb if you didn't install yet and do the following steps.

sudo apt-get install -y xvfb

Dependencies to make "headless" chrome/selenium work:

sudo apt-get -y install xorg xvfb gtk2-engines-pixbuf

sudo apt-get -y install dbus-x11 xfonts-base xfonts-100dpi xfonts-75dpi xfonts-cyrillic xfonts-scalable

Optional but nifty: For capturing screenshots of Xvfb display:

sudo apt-get -y install imagemagick x11-apps

Make sure that Xvfb starts every time the box/vm is booted:

Xvfb -ac :99 -screen 0 1280x1024x16 & export DISPLAY=:99

Now execute google-chrome

Okay guys. I found my problem after 2 hours of going crazy. My box was configured correctly. What you can NOT do, is ssh from one box, to another box, to this box and expect X11 forwarding to play nicely. Without tearing apart the entire network, I found that if I shelled over from the MAIN box to this box ( no double or triple ssh'ing) chrome comes right up as a regular user using CLI. So it was a matter of multiple shells from multiple boxes that made the display say it was set to NOTHING! Setting the display manually only complicates the problems. Once I shelled directly over to this box from the main outside box, my display was set to 10:0, which is first instance in my configuration. Don't make this mistake, you will waste valuable time.

I faced the same issue with WSL and Ubuntu. I have unininstalled/Reset the ubuntu. After that, I have executed the below command

wsl --set-default-version 2

then I installed again the Ubuntu, I didn't get --no-sandbox issue or any issue.

Hope this will use for someone.
