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- eoan' to 'verification-done-eoan'. If the problem still exists, change the tag 'verification-needed-eoan' to 'verification-failed-eoan'.
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.

And the first command we send to scalar is dell_uart_get_scalar_status() to tell if scalar is in charge of the backlight, and it always fails to get response because of timeout. [Fix] Adding retry and increasing read timeout for dell_uart_get_scalar_status() [Test] Verified on the target Dell AIO, it can now read the response from scalar. [Regression Potential] Low, adding retry and increasing read timeout doesn't change the code flow.
