SUMMARY In the Battery and Brightness widget there is a text that reads: "Your laptop is configured not to sleep when closing the lid while an external monitor is connected.". This appears when connecting an external monitor to the Steam Deck. Since the Steam Deck is not a laptop and doesn't have a lid, this text is incorrect. STEPS TO REPRODUCE 1. Go into desktop mode on the Steam Deck 2. Connect an external monitor (I have it set to only use the external monitor, the built-in one is turned off) 3. Open the Battery and Brightness widget
Thank you for the bug report! However Plasma 5.27.10 is no longer eligible for support or maintenance from KDE; supported versions are 5.27. (LTS), and 6.2 (non-LTS) or newer. Please upgrade to a supported version as soon as your distribution makes it available to you. Plasma is a fast-moving project, and bugs in one version are often fixed in the next one. If you need support for Plasma 5.27.10, please contact your distribution, who bears the responsibility of providing support for older releases that are no longer supported by KDE. If you can reproduce the issue after upgrading to a supported version, feel free to re-open this bug report.
I haven't installed a new Plasma version on my Steam Deck, but I found the "Your laptop is configured..." line in the upstream repository at https://invent.kde.org/plasma/powerdevil/-/blob/master/applets/batterymonitor/package/contents/ui/InhibitionItem.qml?ref_type=heads#L106 so I assume it would behave the same way on the current Plasma version as well. It seems that this "inhibitsLidAction" is for some reason "true" for the Steam Deck. That could be a fault with the Steam Deck firmware or a limiation of how "inhibitsLidAction" is calculated.
It's a problem with the firmware or drivers for reporting that it has a lid switch, yeah. I'll report it to Valve.
