I think the workaround can almost be confirmed, I no longer have issues described in this bug report. I am only waiting for Lee Willis to confirm that it works the same for him and IMHO then the workaround can be official.
I have made a script (path-to-my-script) with contents: xinput disable 7 xinput disable 8 xinput disable 17 Then I did: chmod +x path-to-my-script And I have put this in my /etc/lightdm/lightdm.conf: session-setup-script=path-to-my-script And now the workaround is automated and I don't have to wory about it anymore. Note: The numbers after xinput disable are likely to be different on another computer, so you have to first determine, which numbers correspond to Video Bus and another Video Bus and Dell WMI hotkeys. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1293425 Title: [Dell Vostro 3550] Display resolution keeps switching with external monitor connected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1293425/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
