Public bug reported: After performing apt dist-upgrade and rebooting, plymouth doesn't run in full resolution and the graphical session won't start. The system is stuck on a blinking cursor. A full log file is attached. Here is the error:

Please specify busIDs for all framebuffer devices Interestingly, pressing Ctrl+Alt+F1 when the system is stuck successfully starts the XServer and brings up the login screen. While I experience some font rendering issues, most things seem to work fine after that. lsb_release -rd Description: Ubuntu Focal Fossa (development branch) Release: 20.04 uname -a Linux xxxx 5.4.0-14-generic #17-Ubuntu SMP Thu Feb 6 22:47:59 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux The system is a Dell G5 15 5590 laptop using dual intel/nvidia rtx graphics: lshw -c video *-display Beschreibung: VGA compatible controller Produkt: TU106M [GeForce RTX 2060 Mobile] Hersteller: NVIDIA Corporation Physische ID: 0 Bus-Informationen: pci@0000:01:00.0 Version: a1 Breite: 64 bits Takt: 33MHz Fähigkeiten: pm msi pciexpress vga_controller bus_master cap_list rom Konfiguration: driver=nvidia latency=0 Ressourcen: irq:165 memory:ec000000-ecffffff memory:c0000000-cfffffff memory:d0000000-d1ffffff ioport:4000(Größe=128) memory:ed000000-ed07ffff *-display Beschreibung: VGA compatible controller Produkt: UHD Graphics 630 (Mobile) Hersteller: Intel Corporation Physische ID: 2 Bus-Informationen: pci@0000:00:02.0 Version: 00 Breite: 64 bits Takt: 33MHz Fähigkeiten: pciexpress msi pm vga_controller bus_master cap_list rom Konfiguration: driver=i915 latency=0 Ressourcen: irq:152 memory:eb000000-ebffffff memory:80000000-8fffffff ioport:5000(Größe=64) memory:c0000-dffff ** Affects: xorg-server (Ubuntu) Importance: Undecided Status: New ** Attachment added: "Xorg.0.log.old" https://bugs.launchpad.net/bugs/1865870/+attachment/5333029/+files/Xorg.0.log.old ** Attachment removed: "Xorg.0.log.old" https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1865870/+attachment/5333029/+files/Xorg.0.log.old -- 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/1865870 Title: xorg via gdm-x-session fails to start with "Cannot run in framebuffer mode.
