FYI to reproduce I've done this: # Create the disk qemu-img create -f qcow2 /tmp/disk.qcow2 10G
# Boot from the iso and install kvm -drive if=virtio,file=/tmp/disk.qcow2 -m 4096 -cdrom cosmic-desktop-amd64.iso -boot once=d -vga std # After install... Then run with just: kvm -drive if=virtio,file=/tmp/disk.qcow2 -m 4096 -vga std As said passing `-vga std` is optional, but I never got issues with `-vga vmware`, while it sometimes fails also with `-vga qxl` # Can pass -netdev user,id=mynet0,hostfwd=tcp::2222-:22 -device virtio- net-pci,netdev=mynet0 for ssh debugging -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1794280 Title: gdm doesn't start on a fresh installation of Cosmic Desktop Status in gdm3 package in Ubuntu: Won't Fix Status in xorg package in Ubuntu: New Status in gdm3 source package in Cosmic: Won't Fix Status in xorg source package in Cosmic: New Bug description: ubuntu cosmic desktop 20180925 After installation gdm fails to start and there is only a black screen with a blinking cursor on the top left of the screen. gdm3 can be started manually from a tty When this issue happens there is a plymouth crash reported in bug 1794292 ProblemType: Bug DistroRelease: Ubuntu 18.10 Package: gdm3 3.30.0-0ubuntu2 ProcVersionSignature: Ubuntu 4.18.0-7.8-generic 4.18.5 Uname: Linux 4.18.0-7-generic x86_64 ApportVersion: 2.20.10-0ubuntu11 Architecture: amd64 Date: Tue Sep 25 13:54:45 2018 InstallationDate: Installed on 2018-09-25 (0 days ago) InstallationMedia: Ubuntu 18.10 "Cosmic Cuttlefish" - Alpha amd64 (20180925) ProcEnviron: TERM=linux PATH=(custom, no user) LANG=fr_FR.UTF-8 SHELL=/bin/bash SourcePackage: gdm3 UpgradeStatus: No upgrade log present (probably fresh install) mtime.conffile..etc.gdm3.custom.conf: 2018-09-25T13:49:41.053012 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1794280/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
