Unfortunately I have no idea why something is or is not shipped in Focal. Sorry, I did not understand from the above that you cannot build the driver package's EVDI module or library on 20.04. Can you point me to the displaylink.com discussions if those happen to be public? I'm curious.
I can still give it a try on Ubuntu 19.10 to see if I can trigger any kind of freeze with two monitors plugged in via DisplayLink. According to https://packages.ubuntu.com/source/focal/mutter Focal today has libmutter based on 3.34.3 upstream release which already contains backported patches from https://gitlab.gnome.org/GNOME/mutter/merge_requests/953 , so this would be something else. I assume that will be upgraded to 3.36 in 20.04 still. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1853357 Title: display (whole computer?) hangs when I attempt to use DisplayLink with Wayland Status in Mutter: New Status in mutter package in Ubuntu: Incomplete Status in mutter source package in Eoan: Confirmed Status in mutter source package in Focal: Incomplete Bug description: [ Impact ] I am using the DisplayLink driver for Ubuntu provided at https://www.displaylink.com/downloads/ubuntu DisplayLink is working under Xorg, but when I try to use it under Wayland my whole display hangs and I can't even switch to a different VT with Ctrl-Alt-F3 so I think maybe the whole computer is hung? Not certain. [ Test case ] - Install DisplayLink drivers - Start GNOME Shell in wayland mode - Connect to a display-link dock - Expect the shell to work properly and be visible in the external device [ Regression potential ] Wayland session won't work even for standard drm devices ---- I am using the DisplayLink driver for Ubuntu provided at https://www.displaylink.com/downloads/ubuntu, which I think is the only way to get DisplayLink fully working under Ubuntu? That is, DisplayLink didn't work when I installed the evdi-dkms and libevdi0 Ubuntu packages, and I couldn't find any other packages that might be relevant (did I miss something?) so as far as I can tell the only way to get everything that's needed is from displaylink.com. I'm reporting this issue while logged in under Xorg because I can't report it when logged in with my DisplayLink monitors plugged in under Wayland, for obvious reasons. :-/ ProblemType: BugDistroRelease: Ubuntu 19.10 Package: mutter 3.34.1-1ubuntu1 ProcVersionSignature: Ubuntu 5.3.0-23.25-generic 5.3.7 Uname: Linux 5.3.0-23-generic x86_64 ApportVersion: 2.20.11-0ubuntu8.2 Architecture: amd64 CurrentDesktop: ubuntu:GNOME Date: Wed Nov 20 14:08:21 2019 InstallationDate: Installed on 2019-09-12 (69 days ago) InstallationMedia: Ubuntu 19.04 "Disco Dingo" - Release amd64 (20190416)SourcePackage: mutter UpgradeStatus: Upgraded to eoan on 2019-09-20 (61 days ago) modified.conffile..etc.apport.crashdb.conf: [modified] mtime.conffile..etc.apport.crashdb.conf: 2019-10-23T16:51:18.143596 To manage notifications about this bug go to: https://bugs.launchpad.net/mutter/+bug/1853357/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
