Then the main issue: freezes. Do I understand correctly, that so far the freezes have only happened when you have had two monitors attached to the DisplayLink dock? Never with just one monitor?
Which DisplayLink dock do you have? You said changing the display configuration is a sure way to freeze? What do you do exactly, something in GNOME display settings or plugging cables or? I doubt the HDMI vs. DVI or monitor brand/model would have an effect here, so I think you can leave testing those details for later. For now, I would like us to concentrate on Ubuntu 19.10, and the full DisplayLink driver package 5.2.14 which includes the EVDI kernel module and libevdi0. Verify what version of libmutter-5-0 package you have installed exactly. If it's older than the one mentioned here to contain the fix I thought would help, try to get that updated. Let me know what version you have, I can have a go at reproducing the freeze. When your machine freezes, can you access it from a remote, e.g. via ssh? If you can, you could first take a look at the process list: are gnome- shell and DisplayLinkManager running? Do they consume CPU? The next step would be installing a bunch of dbgsym packages and attaching GDB to gnome-shell when it's frozen to see where it is at. Do you know how to do that? ** Bug watch added: gitlab.freedesktop.org/xorg/xserver/issues #909 https://gitlab.freedesktop.org/xorg/xserver/issues/909 -- 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
