This problem is probably related to: "Following Mutter's 3.32.1 release, meanwhile, the developers have now hard-enforced a requirement that graphics drivers on the system either support OpenGL 2.1 or OpenGL ES 2.0 as a minimum."
[https://www.phoronix.com/scan.php?page=news_item&px=GNOME-Shell- Mutter-3.32.1] Although Mesa offers software rendering which supports newer OpenGL. Therefore gdm3 and mutter *should* be detecting that the GPU is too old and falling back. It's a semi-regular problem though, that gdm3 and mutter fail to fall back reliably and the login screen never appears. ** Summary changed: - With AutomaticLogin enabled, logging out lands me on a black screen that's unresponsive to any keyboard input + With AutomaticLogin enabled, logging out lands me on a black screen that's unresponsive to any keyboard input [gnome-shell: Failed to initialize accelerated iGPU/dGPU framebuffer sharing: No matching EGL configs] ** Also affects: mutter (Ubuntu) Importance: Undecided Status: New ** Changed in: gdm3 (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gdm3 in Ubuntu. https://bugs.launchpad.net/bugs/1824588 Title: With AutomaticLogin enabled, logging out lands me on a black screen that's unresponsive to any keyboard input [gnome-shell: Failed to initialize accelerated iGPU/dGPU framebuffer sharing: No matching EGL configs] Status in gdm3 package in Ubuntu: New Status in mutter package in Ubuntu: New Bug description: Just testing Disco and wanted to see what login options are available after adding 'gnome-shell-extensions' and found that logging out lands me on a black screen that's unresponsive to any keyboard input.
