** Description changed: 1.) The release of ubuntu: Description: Ubuntu 25.04 Release: 25.04 2.) The version of the package: - package name: screen - Installed: 4.9.1-1ubuntu0.1 - Candidate: 4.9.1-1ubuntu0.1 - Version table: - *** 4.9.1-1ubuntu0.1 500 - 500 http://archive.ubuntu.com/ubuntu plucky-updates/main amd64 Packages - 100 /var/lib/dpkg/status - 4.9.1-1build1 500 - 500 http://archive.ubuntu.com/ubuntu plucky/main amd64 Packages + package name: screen + Installed: 4.9.1-1ubuntu0.1 + Candidate: 4.9.1-1ubuntu0.1 + Version table: + *** 4.9.1-1ubuntu0.1 500 + 500 http://archive.ubuntu.com/ubuntu plucky-updates/main amd64 Packages + 100 /var/lib/dpkg/status + 4.9.1-1build1 500 + 500 http://archive.ubuntu.com/ubuntu plucky/main amd64 Packages 3.) a) Log in into the graphical user environment. b) Open the gnome terminal. c) Type the command "screen". d) Press enter just to be able to type a command within the screen. e) Deattach from the screen using Ctrl A D. - f) Log out from the graphical user environment (with rebooting). + f) Log out from the graphical user environment (WITHOUT rebooting). g) Log in again. h) Try to attach the screen session (command screen -r). i) I expect the screen session to be normally usable. (It was always the case in other linux systems I tried during past decades). 4.) If I do the steps shown above, i.e. if I detach from an existing screen session, then log out (just log out, no reboot) and then log in, I found the screen session dead: [konopka@thinkpad ~] screen -ls There is a screen on: - 3577.pts-0.thinkpad (25/09/25 10:53:28) (Dead ???) + 3577.pts-0.thinkpad (25/09/25 10:53:28) (Dead ???) Remove dead screens with 'screen -wipe'. 1 Socket in /run/screen/S-konopka. The screen session cannot be normally reattached, it is unusable and my simulation (some long-time running in the command-line session) has also crashed. This is of course annoying. I am reporting this bug from an ubuntu 25.04 notebook but the same bug is present also in ubuntu 22.04 for example. This bug is NOT present in LinuxMint 22.1 Xia (based on ubuntu 24.04). I checked also Lubuntu 22.04. Any screen session is completely removed there upon logout. Even no mention of a dead screen. A note to my way of the screen usage: While being in my office, I start a screen session with a simulation using some command-line driven program like cp2k or cpmd or psi4 or dftb+ or something similar, e.g. a program from the Quantum Espresso package. The program is expected to run overnight. So it is better to deattach the screen to prevent an accidental hit on the running program. And since such program needs a lot of memory, it is convenient to log out from the graphical user environment thus leaving more more memory for the simulation. Unfortunately, the screen then crashes on the mentioned ubuntu systems. I did no encounter such a crashing on any Linux Mint system.
