I wrote to Asus support explaining the issue and answered that is a known issue with the chipsets of that motherboards in some Linux systems.
They said that is a bug in Linux that affects Ubuntu x64, Fedora x64 and Fedora 32-bit. They advised me to try Ubuntu 32-bit, where the problem doesn't appear. I have an idea to avoid the problem, I'm trying and if I success I will post here. -- Keyboard keys repeat https://bugs.launchpad.net/bugs/658072 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
