This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

That guy asked the scalar vendor to add this command and the command works as expected. But there is already a command in the Dell AIO scalar UART command spec. which can do the same thing since 2015, and the newly introduced get_scalar_status command is undocumented. To prevent from introducing regression in the future and to align with what Windows uses, replace this command with get_display_mode command. [Fix] Replace get_scalar_status command with get_display_mode command. [Test] Verified on new Dell AIO platforms. [Regression Potential] Low, the command is already in the spec. since 2015.
