[Ubuntu-x-swat] [Bug 1801747] Re: External display not recognized, internal one goes to black
More infos. I installed the notebook from scratch with a 16.04.2 image and update to latest 16.04 packages which installed 4.15.0-38 kernel. The laptop has the correct behavior, without entering settings I can switch/duplicate displays with the fn key. So original problem seems not related to kernel version. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1801747 Title: External display not recognized, internal one goes to black To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1801747/+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

[Ubuntu-x-swat] [Bug 1801747] Re: External display not recognized, internal one goes to black
Ubuntu 18.10 does have the same problem, Ubuntu 16.04.2 has *NO* problem. From where could I get an 4.4 kernel for 18.04 for testing purpose ? Other infos: when I check in systems, it show me 3 display despite the fact that only 2 are connected: 1. internal display 2. unknown display with resolution 1024 x 768 (4:3) 800 x 600 (4:3) 848 x 480 (16:9) ! 3. external display with correct informations (Brand, model, ) I also discover that starting the laptop with the display connected, shows me the splash image on both displays as it should. Problem arise on greeting image. From here I see "No input signal" and the external display goes black. Daniel PS: perhaps bug 1723025? could be identical but from my side, I can start with or without external display, it's only when I use the fn switch key that problem arise. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1801747 Title: External display not recognized, internal one goes to black To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1801747/+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

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.19 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.
