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 Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
