I've found the kernel code that is not processing this key-event. https://github.com/torvalds/linux/blob/master/drivers/platform/x86/dell- wmi.c#L218
Is there any way that the event is NOT ignored by that code in the case of the Dell XPS 15 9550? (It was initially designed for Dell XPS 13 9350, where the intel-wifi-driver handles the hotkey event) I'll try the kernel mentioned by @jsalisbury -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1589886 Title: Wireless hotkey fails on Dell XPS 15 9550 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1589886/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
