To reproduce this, click Application (or Super + A), Hover over to the Firefox Icon, right click.

there are "New Window" "New private window" and "Open Profile manager"..

the last one wasn't here before the update. can i get rid of it?

[–] [email protected] 1 points 1 year ago

worth noting that I updated all my virtual machines created with 36.iso to the latest kernels, etc, and they function without any problems..

I can't get the fresh installs using 37.iso and 38.iso to function (always blank screen)

QEMU cannot launch the latest Pop!_OS image (lemm.ee)
 

I'm using the virt-manager to install Pop!_OS on a virtual machine from the latest ISO image (...38.iso) with QEMU for testing:

GRUB starts okay, running the tests. Then the QEMU window turns completely black and nothing changes for hours. This didn't happen with the previous ...36.iso of the image.

Any help is highly appreciated. Thank you!

note that, this issue has been around since ...37.iso

and these settings stay the same.

To do that you need to:

set WaylandEnable=true in /etc/gdm3/custom.conf
reboot
at the log in screen, there is a small gear wheel on the bottom right side, choose “Pop on

thanks, I will try that, is there any issue with wayland so far? cause its no t officially enabled yet

Optimize Pop with external monitor? (lemm.ee)
 

my laptop resolution is 2256x1504, while my monitor has standard 1920x1080. when I start Pop is always default 200% scale, even I changed it to 100% before. I have to manually set it to 100% scale on my laptop and monitor. But it would not sustain. When I unplug hdmi and reconnect, everything goes back to default. Is there any ways I can optimize this? thank you

can Pop! maintain supermin? (lemm.ee)
 

the maintainer is currently Ubuntu, but they stuck at version 5.2.1, which was released in Jan 2021. would Pop! compile a more updated version (say 5.3.1)?

zstd formated Kernel has conflicts with the 5.2.1, causing issues with libguestfs, but it's fixed upstream on 5.3.1+.

Qemu/kvm has problems with kernel 6.5.4 (lemm.ee)
 

virt-sparsify

libguestfs-test-tool

both yield similar error:

supermin: waiting another 1024000000 ns for root UUID to appear
This usually means your kernel doesn't support virtio, or supermin was unable
to load some kernel modules (see module loading messages above).
supermin: waiting another 2048000000 ns for root UUID to appear
supermin: waiting another 4096000000 ns for root UUID to appear

Is there any ways I can test running on a newer kernel?
