Title:
[SRU] Studio-controls not launching on Ubuntu 21.10, KeyError: 'id'
Status in studio-controls package in Ubuntu:
Fix Released
Status in studio-controls source package in Impish:

Bug description:
[ Impact ]
Users in certain edge cases of hardware configurations are running
into issues where studio-controls is failing to upgrade previous
configurations and therefore failing to launch. It was found that an
integer needed to be converted to a string in some cases, and was
overlooked previously.
[ Test Plan ]
Using a system that had been upgraded from 20.04 to 20.10, 21.04, and
finally 21.10 and having run studio-controls previously with success,
run studio-controls. In certain hardware configurations, it will crash
and return invalid key of "id". This is due to an incorrect conversion
of the old-style configuration to the newer json configuration.
[ Where problems could occur ]
While this fixes the issue outlined above, it could cause problems
where the json file was previously converted correctly, but this is
unlikely.
[ Other Information ]

Hi,
I am using studio-controls 2.2.7-0ubuntu1 after having upgraded to
Impish. Studio-controls fails to launch with the following traceback:
install path: /usr
Config file: /home/steve/.config/autojack/autojack.json
Traceback (most recent call last):
File "/usr/bin/studio-controls", line 1837, in <module>
us = StudioControls()
File "/usr/bin/studio-controls", line 555, in __init__
self.devdb.scan_dev(self.conf_db)
File "/usr/bin/studio-controls", line 164, in scan_dev
if usb and [ conf['devices'][dev]['id'], conf['devices'][dev]['bus'] ] ==
[ d_id, bus ]:
KeyError: 'id'
Here is my system info:
Operating System: Kubuntu 21.10
KDE Plasma Version: 5.22.5
KDE Frameworks Version: 5.86.0
Qt Version: 5.15.2
Kernel Version: 5.13.0-21-lowlatency (64-bit)
Graphics Platform: X11
Processors: 8 × Intel® Core™ i7-8550U CPU @ 1.80GHz
Memory: 15.3 GiB of RAM
Graphics Processor: Mesa Intel® UHD Graphics 620
I do have the file autojack.json in .config/autojack that is referred
to in another bug report.
After failing to launch, I have a studio-controls.lock file created in
the .config/autojack directory. The studio-controls interface does
not appear at any time.
Last point, I'm using Pipewire, as I was before upgrading to 21.10,
which didn't create a problem with Studio-controls then. I would like
to continue to use Studio-controls to control cpu performance and
intel boost, and possibly other things.
Thanks !!
Stephen
