Public bug reported: The following command:
$/etc/X11/Xsession true opens a dialog with the following error message: "Xsession: unable to launch "true" X session --- "true" not found; falling back to default session." There is a "Okay" button on this message, and clicking it does bad things if one happens to be running Ubuntu 22.04 on Xorg (or running Gnome on Xorg, which is seemingly a different option for the the low latency installation I am running: 5.15.0-43-generic #46-Ubuntu SMP Tue Jul 12 10:30:17 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux). See Brendan O'Dea's related comment about this behavior on debian-bugs- dist: https://www.mail-archive.com/debian-bugs- d...@lists.debian.org/msg1857023.html This has consequences in my use of xpra. For example, if I use xpra via the run_scaled-master script to magnify a single application's interface for a 4K display I get the error dialog mentioned above, often with resulting system instability. This behavior cropped up last month.
