So far, it seems that disabling JUST id=8 works fine. If both are enabled, the original problems remain (as expected). If I only disable id=7, problems are the same.

Lee Willis - that's very nice to hear! Yeah, it would be interesting to know the actual issue, so I would also like the developers to further investigate it. If it were purely hardware error, the switching would occur in Windows (7 in my test case) too, but it doesn't.

[Ubuntu-x-swat] [Bug 1293425] Re: [Dell Vostro 3550] Display resolution keeps switching with external monitor connected
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-X, which is subscribed to xorg in 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 ___ 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

Found a related bug IMHO: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1063658 With that one 'xinput disable x' was also workaround. If you go and read that bug report, you can see that it really is about the same thing, only that the user didn't use external monitor for a while and when he did, he reported If second monitor is plugged flickering of windows stops and system starts to turn off and on both monitors with different resolutions. - sounds like he's talking about the same thing to me.

[Ubuntu-x-swat] [Bug 1293425] [NEW] [Dell Vostro 3550] Display resolution keeps switching with external monitor connected
Public bug reported: My laptop is DELL Vostro 3550. BIOS A11. If I use external monitor and extend my desktop to both the built-in laptop display and the external LCD, the display settings are auto-changed by the system. This may include: - Resetting to mirrored displays at 1024x768 - Resetting to a single display on the laptop panel - Resetting to a single display on the external monitor I am finding though that the issue is worse by far if I use AMD GPU than if I use Intel GPU. I switch between them with AMD CCC, however the issue is present even if I never install AMD drivers and just use Intel GPU out-of-the-box. So, if I use AMD GPU my monitors keep switching between resolutions, mirroring switches on and off very frequently - like more times every minute. If I use Intel GPU I can go a day without spontaneous switching of resolutions and/or mirroring displays, sometimes it happens like 2 or 3 times per day.
