= Ubuntu 23.04 boot broken on kernel 6.2
{c}
On <ciro santilli s hardware/Lenovo ThinkPad P51 (2017)>.
Switching to the other installed kernel, 5.9 made boot work.
The solution on kernel 6.2 was:
``
sudo apt instal nvidia-driver-515
``
as per comments under: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2012559[]. This also made the nvidia driver work: <Find GPU information in Ubuntu>.
Previously I had:
``
nvidia-driver-510
``
and it blew up before reaching disk decryption.
I also tried:
``
nvidia-driver-525
``
but that broke in a different way:
``
Finished apport-autoreport.service - Process error reports when automatic reporting is enabled.
nvidia-modeset: ERROR: GPU:0: Idling display engine timed out: 0x0000947d:0:0:407
(1 of 2) Job systemd-backlight@backlight: nvidia_e.service/start running (32s no limit)
``
