I'm testing this and it's a step backwards. The screen just turns black for the first 6 seconds or so while Plymouth waits for i915drmfb to start instead (might be Plymouth's fault for being too picky?). FB_EFI was better because it at least put the BIOS logo on the screen. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1965303 Title: Migrate from fbdev drivers to simpledrm and DRM fbdev emulation layer Status in gdm: Fix Released Status in linux package in Ubuntu: Confirmed Status in nvidia-graphics-drivers-470 package in Ubuntu: Fix Released Status in linux source package in Jammy: Won't Fix Status in nvidia-graphics-drivers-470 source package in Jammy: Fix Released Status in linux source package in Lunar: Won't Fix Status in nvidia-graphics-drivers-470 source package in Lunar: Fix Released Status in linux source package in Mantic: Won't Fix Status in nvidia-graphics-drivers-470 source package in Mantic: Fix Released Status in linux package in Fedora: Fix Released Bug description: [ Impact ] The fbdev subsystem has been deprecated for a long time. We should drop it in favour of using simpledrm with fbdev emulation layer. This requires Kernel config changes: FB_EFI=n FB_VESA=n fbcon will still require FB to be available, but will use the fbdev emulation layer [ Test Plan ] * Ensure that systems currently relying on fbdev (and therefore only allowing Xorg logins) such as some virtual machine types, boot with working Wayland support. [ Where Problems could occur ] * When this stack is enabled, it changes boot timing such that some drivers may take a longer time to boot and GDM may hang in a black screen (bug 2039757). * Race conditions could be exposed to DE environments * Software that expects to find DRM device at /dev/dri/card0 may have a problem. * Some older versions of NVIDIA driver might not work properly.
