On my Thinkpad X230 using Intel integrated graphics with i915, I get a black screen on boot of elementaryOS 6 instead of plymouth. I can still enter my encryption password into the black screen and then I‘m greeted with the login manager shortly after.
First, i realized that kernel modesetting was seemingly disabled:
# cat /sys/module/i915/parameters/modeset -1
I managed to enable it with
options i915 modeset=1
/etc/modprobe.d/i915.conf and a subsequent
update-initramfs -u. But plymouth still shows a black screen. I also added
/etc/initramfs-tools/modules and added
i915.modeset=1 to my grub commandline parameteres. None of these help.
I have the following error message in my journal:
# journalctl -b 0 | grep plymouth [...] plymouth: unexpectedly disconnected from boot status daemon
I also tried adding
GRUB_GFXMODE with the native screen resolution in
/etc/default/grub, but it didn’t help. Plymouth works fine on the same machine using Arch Linux. I’m out of ideas. Does anybody here have one?
