Thank you for your bug report. The script isn't part of upstream xorg- server, where did you see that --auto-servernum has been deprecated?
The script for Debian (and such Ubuntu) is on https://salsa.debian.org/xorg-team/xserver/xorg-server/-/blob/debian-unstable/debian/local/xvfb-run it seems fedora also has a copy which they patched some years ago to mark that option as deprecated and add auto-display instead, unsure what was the motivation behind the change though https://src.fedoraproject.org/rpms/xorg-x11-server/c/9e2c5679 ** Changed in: xorg-server (Ubuntu) Importance: Undecided => Low -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1976249 Title: `xvfb-run` doesn't support `--auto-servernum` To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1976249/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
