Title:
Force update keyboard LEDs after calling EnableDevice to fix its
hardware state after VT switching
Status in OEM Priority Project:
New
Status in X.Org X server:
New
Status in xorg-server package in Ubuntu:
New
Bug description:
[ Impact ]
* This change will force update keyboard LED status after calling
EnableDevice, in order to resolve LED status not syncing after
switching VT to a X session.
* This also fixes the issue with NVIDIA driver and Xorg, that after
resuming from suspend the keyboard LED is always off.
[ Test Plan ]
1. Log onto an GNOME session (KDE Kwin worked this issue around)
2. Turn on NumLock on the keyboard
3. Use Ctrl-Alt-F3 to switch to a text console, then Ctrl-Alt-F2 to
switch back to desktop
NumLock LED should be on after switching back to the desktop
[ Where problems could occur ]
* The changes are to push status to the device when enabling it
regardless of actual keyboard state change, therefore switching
between VTs and adding/removing keyboard/mouse/xinput devices should
be affected by this change.
[ Original Report ]
Switching virtual terminals [Ctrl-Alt-F1 - F7] to a X session turns
off keyboard LEDs.
This issue is reproducible on 2:21.1.3-2ubuntu2.1 (on 22.04)
To reproduce:
1. Log on a X session desktop (GNOME Xorg for example)
2. Turn on NumLock
3. Use Ctrl-Alt-F3 to switch to a text console, then Ctrl-Alt-F2 to switch
back to desktop
Expected:
NumLock LED should be on
Actual:
NumLock LED is off, but functions like NumLock is on. If NumLock is pressed
the LED turns off as well as the function. If CapsLock is pressed the LED
states sync back (LED turns back on).
