OK I've got simpledrm working now. It needed: FB_EFI=n FB_VESA=n CONFIG_SYSFB_SIMPLEFB=y CONFIG_DRM_SIMPLEDRM=y
So now I have working graphics very early: [ 0.588237] [drm] Initialized simpledrm 1.0.0 20200625 for simple-framebuffer.0 on minor 0 ... [ 7.153876] [drm] Initialized i915 1.6.0 20230929 for 0000:00:02.0 on minor 1 But this doesn't seem to solve bug 1970069, just reintroduced it on simpledrm instead of efifb: [ 1.959016] fbcon: Taking over console -- 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.
