[Bug 1945873] Re: vt.handoff=7 ~broken on VM
Quick note, removing "splash" from the kernel command line mitigates the issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1945873 Title: vt.handoff=7 ~broken on VM To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1945873/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1945873] Re: vt.handoff=7 ~broken on VM
I just installed Impish Indri on my Thinkpad T420 and the same issue cropped up. This is notable in that it is a UEFI install on real hardware. I'd expected this was a glitch that would only show up on VMs. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1945873 Title: vt.handoff=7 ~broken on VM To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1945873/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1945873] Re: vt.handoff=7 ~broken on VM
I've been lax in exercising this stuff. I tend to stick to Ubuntu LTS hypervisors (hence hardware), and my VMs are often other systems. I only noticed this issue because I needed a VM test environment for the un- related ZFS root bug I was exploring. I haven't ruled out that it's an artifact of my install method, although if it is, that itself might indicate a missing explicit dependency somewhere. I'll try to get time to do a vanilla install using one of the shipped installers, and I'll report back with results. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1945873 Title: vt.handoff=7 ~broken on VM To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1945873/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I'm surprised to see this is the case, I thought the switch to vt1 had been completed several cycles ago. ** Changed in: grub2 (Ubuntu) Status: New => Triaged -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1945873 Title: vt.handoff=7 ~broken on VM To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1945873/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Additional detail in case it's useful: Hypervisor is Debian Buster, virt-manager, libvirt/KVM, default Spice display, default QXL video.
