Selenium and Chrome DevToolsActivePort file doesn't exist after 89/90 chrome invocations about pyvirtualdisplay HOT 4 OPEN

I seem to be getting a similar issue. I started getting it after the latest update of xvfb so I am suspecting it is an issue with xvfb.
Are you using the latest version in ubuntu too? Could you share your xvfb version (apt-cache policy xvfb | grep Installed)?

from pyvirtualdisplay.

$ apt-cache policy xvfb | grep Installed
Installed: 2:21.1.4-2ubuntu1.7~22.04.7

from pyvirtualdisplay.

Well I can confirm that my issue or at least part of my issue was in the latest version of xvfb on ubuntu.
I don't get any issue if I downgrade.

Since it is not available on the official repo anymore. I did:

wget -O /tmp/xvfb.deb http://launchpadlibrarian.net/702315346/xvfb_1.20.13-1ubuntu1~20.04.12_amd64.deb
apt install -y --allow-downgrades /tmp/xvfb.deb

But since I see you are on jammy, your last package is probably this instead:

http://launchpadlibrarian.net/702313861/xvfb_21.1.4-2ubuntu1.7~22.04.5_amd64.deb

If it works for you too it should confirm that we had the same issue and that there is something weird going on with the latest version of xvfb.

Thanks for the pointers. Downgrading xvfb worked for visibility=0 so your diagnosis looks good but I still get same failure at 89 with visible=1 suggesting there is also an issue in xephyr? (Not that I need visibility=1 got my use case)

display.py backend selection:

            if self._visible:
                self._backend = "xephyr"
            else:
                self._backend = "xvfb"
