[Bug 1881687] Re: Desktop is blank after logging in without a monitor attached
Thanks. Yes indeed the X server has zero monitors attached, but still has a usable desktop area of 1024x768. For gnome-shell this just means it won't draw any panel/launcher etc. Because it prefers to only do that on the primary monitor, which there is none. Next please report the bug to the gnome-shell developers at: https://gitlab.gnome.org/GNOME/gnome-shell/issues and then tell us the new issue ID. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1881687 Title: Desktop is blank after logging in without a monitor attached To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1881687/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Can you please ssh into the machine while the desktop is "blank" and tell us how many 'gnome-shell' processes are running?

Also from ssh please try running: env DISPLAY=:0 xrandr or env DISPLAY=:1 xrandr and tell us what output you get. ** Package changed: xorg (Ubuntu) => gnome-shell (Ubuntu) ** Also affects: mutter (Ubuntu) Importance: Undecided Status: New ** Changed in: gnome-shell (Ubuntu) Status: New => Incomplete ** Changed in: mutter (Ubuntu) Status: New => Incomplete ** Changed in: gnome-shell (Ubuntu) Importance: Undecided => Low ** Changed in: mutter (Ubuntu) Importance: Undecided => Low -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1881687 Title: Desktop is blank after logging in without a monitor attached To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1881687/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1881687] Re: Desktop is blank after logging in without a monitor attached
based on my research so far (and summarized in the description), I don't think this is an xorg issue. I think it's a gnome issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1881687 Title: Desktop is blank after logging in without a monitor attached To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1881687/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1881687] Re: Desktop is blank after logging in without a monitor attached
** Description changed: On Ubuntu 20.04, I have an AMD system with an integrated GPU (Ryzen 3 3200G with Radeon Vega 8) - I am using lighdm instead of gdm3. My GPU is using the amdgpu driver. I have no specific xorg.conf in place. I am using x11vnc to login and view the desktop remotely. There is no monitor attached. + I am using lightdm instead of gdm3. My GPU is using the amdgpu driver. I have no specific xorg.conf in place. I am using x11vnc to login and view the desktop remotely. There is no monitor attached. After logging into lightdm's greeter, I am presented with a blank desktop with the Focal Fossa background image and a mouse cursor, but no other visible interface or windows. There is no menu bar at the top of the desktop and no application bar on the left. This all works perfectly fine if a monitor is attached before lightdm (and thus Xorg) is started. If I change the settings at login to use fvwm for my session it works fine. This is also the case for Gnome Flashback mode (using metacity). But the default of gnome-shell/mutter does not work without the monitor. Nor does using Wayland.
