When I run the w command the TTY is shown as -

Like this:
# w
  18:05:00 up  2:32,  1 user,  load average: 0.57, 0.63, 0.93
USER     TTY      FROM             LOGIN@   IDLE   JCPU   PCPU  WHAT
c                 -                15:33           0.00s   ?    lightdm --session-child 15 26

I expect a value to be shown, in this case tty7

The fgconsole command shows the tty number

# fgconsole
7

I am using Debian testing.  Some uname -a output:
Linux 6.12.27-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.12.27-1 (2025-05-06) x86_64 GNU/Linux

The desktop is Xfce 4.20.0

Best
