Package: kmscon
Version: 9.0.0-4
Severity: normal
Dear Maintainer,
when launching kmscon at any vtN and switching on another vtN by Ctrl+Alt+Fn,
after switching back to the kmscon the keyboard is rendered unusable,
as any keypress is regarded as if Ctrl was pressed (e.g. C brings ^C, L clears
the screen like Ctrl+L etc). Strangely, D doesn't end the session like Ctrl+D
would do.

This modifier-state race was fixed upstream by e083e3c (#315), first included
in Debian 9.3.3-1.
I reproduced stuck Ctrl in 9.0.0-4 using a controlled VT-switch test. Debian 10.0.4-3 and current upstream main
correctly clear the modifier state under the same conditions.
Marking as fixed. Please let us know if this still occurs with a current
version.
