This is the debdiff for groovy.

@Hui, thanks, could you request upstream to cherry pick the fix to gnome-3-38, it would make the next SRU easier

@seb,

Done, just added a comment in the MR to request to cherry-pick the patch to gnome-3-38.

Thanks, the SRU has been uploaded to focal queue

Hello Hui, or anyone else affected,

Accepted gnome-control-center into focal-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/gnome-control-center/1:3.36.4-0ubuntu2 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-focal to verification-done-focal. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-focal. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

Tested on one Lenovo and one Dell machines, they all use legacy HDA audio driver. Upgraded the g-c-c to 0buntu2, plug a hdmi/dp monitor, we could see the hdmi-stereo from the configuration combo list and audio worked well. Without this SRU, users will see the empty configuration combo list and need users manually select profile.

Verified done on focal.

I install a dell machine (still not disclosed), upgrade everything from updates channel, and install from focal-proposed

Get:1 http://archive.ubuntu.com/ubuntu focal-proposed/main amd64 gnome-control-center-data all 1:3.36.4-0ubuntu2 [327 kB]
Get:2 http://archive.ubuntu.com/ubuntu focal-proposed/main amd64 gnome-control-center amd64 1:3.36.4-0ubuntu2 [1,718 kB]
Get:3 http://archive.ubuntu.com/ubuntu focal-proposed/main amd64 gnome-control-center-faces all 1:3.36.4-0ubuntu2 [1,216 kB]

After that, I reboot the machine, plug hdmi, make sure hdmi output is selected in g-c-c.

I still can see three items in the profile combo list.

@Hui, could you check that verification failed comment, is that the same issue than is addressed here or a different one, the 'three items' description sounds a bit different

@YC,

This SRU is not to fix the 3 profiles in the combo list, it is to fix the issue of "no active profile in the combo list" after plugging the hdmi/dp monitor.

Without this SRU, after users plug a hdmi/dp monitor, the profile combo list is empty, need users manually to select profile from 3 ones.

After the SRU, an active profile will be shown automatically in the combo list after users plug a hdmi/dp monitor, no need users to manually select the profile, but there are still 3 profile options in the combo list. This is same as the 18.04.

Given the details in #11, yes with the new g-c-c, I can see the first profile auto-selected.
Without updated g-c-c, it's not auto-selected.
