** Description changed: The freeze causes the mouse cursor to stop moving and keyboard to stop responding and nothing moves on screen, not even the clock. Curiously the music continues to play (and e.g. sound from youtube video continues to be played even though the video itself freezes and no longer animates on-screen). It appears that the freeze happens quite randomly; I am not able to figure out what it's caused by. Sometimes it's caused by launching the Snap Chromium, or perhaps by a notification shown, but I do not know for sure. I also tried to hunt system logs and/or systemd gnome-shell logs, but I failed to discover some kind of crash dump. Curiously the Ctrl+Alt+F2 key combo stops working. That leads me to believe that it's some kind of kernel+nouveau crash, but I can't seem to discover any kernel panic in the system logs. After the gnome-shell freezes, the numlock light still responds to numlock key presses. However, mashing Ctrl+Alt+Del has no effect, so I'm only able to reboot via Alt+Sysrq+s u b. Thank you :) ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: gnome-shell 3.36.1-5ubuntu2 ProcVersionSignature: Ubuntu 5.4.0-29.33-generic 5.4.30 Uname: Linux 5.4.0-29-generic x86_64 ApportVersion: 2.20.11-0ubuntu27 Architecture: amd64 CasperMD5CheckResult: skip CurrentDesktop: ubuntu:GNOME Date: Tue May 12 11:20:36 2020 DisplayManager: gdm3 InstallationDate: Installed on 2016-09-05 (1344 days ago) InstallationMedia: Ubuntu-Server 16.04.1 LTS "Xenial Xerus" - Release amd64 (20160719) RelatedPackageVersions: mutter-common 3.36.1-3ubuntu3 SourcePackage: gnome-shell UpgradeStatus: Upgraded to focal on 2020-03-20 (52 days ago) + --- + ProblemType: Bug + ApportVersion: 2.20.11-0ubuntu27 + Architecture: amd64 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC2: mavi 2227 F.... pulseaudio + /dev/snd/controlC0: mavi 2227 F.... pulseaudio + CasperMD5CheckResult: skip + CurrentDesktop: ubuntu:GNOME + DistroRelease: Ubuntu 20.04 + HibernationDevice: RESUME=/dev/mapper/vg0-lv0--swap + InstallationDate: Installed on 2016-09-05 (1360 days ago) + InstallationMedia: Ubuntu-Server 16.04.1 LTS "Xenial Xerus" - Release amd64 (20160719) + MachineType: LENOVO 20EN0005MS + Package: linux (not installed) + ProcFB: 0 nouveaudrmfb + ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-5.4.0-31-generic root=/dev/mapper/vg0-lv1--root ro splash ipv6.disable=1 nouveau.modeset=1 vt.handoff=7 + ProcVersionSignature: Ubuntu 5.4.0-31.35-generic 5.4.34 + RelatedPackageVersions: + linux-restricted-modules-5.4.0-31-generic N/A + linux-backports-modules-5.4.0-31-generic N/A + linux-firmware 1.187 + Tags: wayland-session focal + Uname: Linux 5.4.0-31-generic x86_64 + UpgradeStatus: Upgraded to focal on 2020-03-20 (67 days ago) + UserGroups: adm cdrom dip docker kvm lpadmin lxd plugdev sambashare sudo video + _MarkForUpload: True + dmi.bios.date: 12/06/2019 + dmi.bios.vendor: LENOVO + dmi.bios.version: N1EET87W (1.60 ) + dmi.board.asset.tag: Not Available + dmi.board.name: 20EN0005MS + dmi.board.vendor: LENOVO + dmi.board.version: SDK0J40705 WIN + dmi.chassis.asset.tag: No Asset Information + dmi.chassis.type: 10 + dmi.chassis.vendor: LENOVO + dmi.chassis.version: None + dmi.modalias: dmi:bvnLENOVO:bvrN1EET87W(1.60):bd12/06/2019:svnLENOVO:pn20EN0005MS:pvrThinkPadP50:rvnLENOVO:rn20EN0005MS:rvrSDK0J40705WIN:cvnLENOVO:ct10:cvrNone: + dmi.product.family: ThinkPad P50 + dmi.product.name: 20EN0005MS + dmi.product.sku: LENOVO_MT_20EN_BU_Think_FM_ThinkPad P50 + dmi.product.version: ThinkPad P50 + dmi.sys.vendor: LENOVO ** Attachment added: "AlsaInfo.txt" https://bugs.launchpad.net/bugs/1878166/+attachment/5377343/+files/AlsaInfo.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1878166 Title: Kernel crash in nouveau with Wayland To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1878166/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
