When the privacy screen functionality is enabled, I see the following warnings in the logs:
[188829.782403] hp_wmi: Unknown event_id - 20 - 0x46fe [188834.848948] hp_wmi: Unknown event_id - 20 - 0x3c00 [188835.624987] hp_wmi: Unknown event_id - 20 - 0x4600 The first warning is when I press the privacy screen button (fn-f2). The second is when I press the brightness down button (fn-f3). The third is when I press the brightness up button (fn-f4). I do not see similar warnings after the privacy screen functionality is turned off and I press the brightness up or down hotkeys. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1861521 Title: [FOCAL][REGRESSION] HP EliteBook 840 G5 screen brightness cannot be controlled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-signed-5.4/+bug/1861521/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
