** Also affects: mutter (Ubuntu)
Importance: Undecided
Status: New
** Description changed:
The laptop shipped with Lenovo's 6.5.0-1019-oem, but upon upgrades
switched to 6.8.0-47-generic which is generally preferred because
6.5-oem is no longer seeing updates.
However, there is a regression that Fn+D Lenovo Privacy Guard does not
switch correctly on. Instead, it only briefly flashed on and immediately
back off, with "Privacy screen enabled" followed immediately by "Privacy
screen disabled" at the bottom of the screen.
This bug used to indicate it's clearly a kernel regression, but it may
- be also a regression in some other component.

+ string, but downgrading that to 42.9-0ubuntu7 the machine shipped with

## Test Case
Laptop model: Lenovo Thinkpad T14s Gen 5 (Intel) with vendor support
Ubuntu 22.04 LTS (oem-sutton-carr-meta)
1. Boot to desktop, check that Fn+D is functional both to turn the feature on
and off
2. Attach external display, and try again.
3. Detach external display, try again.
4. Reboot, and try again.
## Expected Behavior
Fn+D works as intended in all cases. This is how it worked as the laptop
shipped, with 6.5.0-1019-oem as the kernel.
## Actual Behavior
Fn+D only results in a "flashing" Privacy Guard being activated but
immediately deactivated, so that it does not stay on.

- Bug description updated to reflect I can no longer find a way for it to
behace correctly, but it did behave correctly in the configuration it shipped
in, after which only offered upgrades have been done.
