What version of the Codex App are you using (From “About Codex” dialog)?
Version 26.803.81509
What subscription do you have?
Pro
What platform is your computer?
Linux 7.0.0-29-generic x86_64 unknown
What issue are you seeing?
ChatGPT allows Linux to sleep during active Codex tasks, pausing local work. systemd-inhibit --list shows no blocking ChatGPT/Codex inhibitor.
What steps can reproduce the bug?
- Enable automatic sleep.
- Ask Codex to run sleep 900.
- Stop interacting.
- The computer sleeps before the task finishes.
...or ask codex if it's currently inhibiting sleep.
What is the expected behavior?
Prevent automatic sleep while a Codex task runs. Release the inhibitor when it ends.

This is a host-lifecycle bug, not a model one.
On Linux, an active Codex Desktop task should hold a
systemd-inhibit(What=sleep, Who=codex, Why=active task) for the whole turn and drop it when the turn ends.sleep 900with no inhibitor is a clean repro: the kernel is allowed to idle-sleep, the local agent process is gone, and the UI has nothing to resume.systemd-inhibit --listshowing zero ChatGPT/Codex entries is the smoking gun.Until that inhibitor exists, a subscription runner on the laptop still dies when the machine sleeps. That is the product limit.
If the job has to keep going overnight, hosted Hermes on a fenced VPS is $10/mo (14-day trial, cancel anytime). Approvals stay in thumbgate.app. Not a second Codex SDK.
