you have to press ESC twice in far2l in kernel console

[Unxed]

[ Impact ]

This bug affects users of the far2l console file manager on Ubuntu. Users need to press ESC twice instead of once while working in kernel console. This behavior is unexpected and can be annoying, disrupting the user's workflow.

The upstream patch (https://github.com/elfmz/far2l/pull/2314/files) addresses this issue by correcting the ESC key handling logic, ensuring that a single press of the ESC key work as intended. Backporting this fix to the stable release will improve the user experience for far2l users by eliminating this small but frustrating bug.

[ Test Plan ]

Reproduce the bug:

1. Open a kernel console (Ctrl+Alt+F3).
2. Log in.
3. Run far2l.
4. Press F1 to open the help screen.
5. Press ESC once. Observe that the help screen does not close.
6. Press ESC a second time. The help screen should now close.

Apply the patch and rebuild the package. Verify the fix:

Repeat steps 1-5 from the "Reproduce the bug" section.

Observe that pressing ESC once now successfully closes the help screen.

[ Where problems could occur ]

The patch code utilizes ioctl to determine the kernel console mode. In rare cases, the ioctl call might return an unexpected value, which could lead to enabling "esc expiration" mode in environments where it is not needed (e.g. in ttyxi mode). This may lead to small delays in ESC key handling in those environments.

[ Other Info ]

User impact: This bug is a minor annoyance rather than a major blocker, however, it is a common use case and fixing it will improve the overall user experience.
