I recently SOLVED this issue, sorry if I didn't wrote an update here. The trick (I'm not completely sure) was going to KDE System Settings > "Keyboard and mouse", and playing a bit with "Enable keyboard repeat" in the Keyboard page.
Maybe I just activated then deactivated it, then my problems with multimedia keys are gone. As I told you, I'm not completely sure on what resolved the multiple key presses issue, but I was playing with settings in that page and suddenly the issue is gone (also after rebooting the system). -- Dell XPS M1330 volume keys as pressed two times https://bugs.launchpad.net/bugs/310270 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
