While checking wmi event codes I discovered that after pm-suspend and resume wmi events are no longer sent. All wmi buttons stopped working (except for volume buttons).
Reloading dell-laptop fixed it. However, that is unrelated issue, I believe. I will try without Michał's patch to see if that's the case. ** Attachment added: "M5110_wmi_events.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1205791/+attachment/4434624/+files/M5110_wmi_events.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1205791 Title: Dell Vostro V131: special keys not working To manage notifications about this bug go to: https://bugs.launchpad.net/udev/+bug/1205791/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
