I recently flashed my BIOS chip with either GNUboot and libreboot. But I have not been able to get my external graphics card to work. The only error I could find regarding to nouveau is:

... vgaarb: changed VGA decodes: olddecodes=io+mem,decodes=none:owns=none

Does anyone know what could cause this error, or in what direction to look? Everything worked before flashing. Now only able to get display with serial cable and on-board graphics.

My system is set up for hibernation and everything works mostly fine. However sometimes the system won't hibernate. When I issue the hibernate command it disconnects WiFi but doesn't go to sleep. A few seconds later it reconnects WiFi. This is all I could observe. It doesn't matter wether I close the laptop lid or if I issue the sudo systemctl hibernate command. **How can I troubleshoot and finally remove the problem?** Here's my system Info: - Librebooted X440p with fully encrypted lvm. - Hibernating to swapfile: - mkinitcpio: HOOKS=(base udev autodetect modconf kms keyboard keymap consolefont block encrypt lvm2 filesystems resume fsck) If you need any further info, just ask along. Thanks in advance! **Edit:** I managed to get into the situation where the machine won't hibernate. This is the output of swapon:

❯ swapon
NAME      TYPE SIZE USED PRIO
/swapfile file  16G 256K   -2

I will be trying to flash LibreBoot (a particular coreboot downstream) on to a thinkpad T440p. Even with libreboot - instructions are quite complex, but look entirely doable. There is one thing, however - I cannot be sure if I can make the boot roms using lbmk on a relatively powerful linux computer (running manjaro/arch) and then flash using RaspberryPi, or must I make the roms on the raspberrypi that I will be using for flashing (with a SOIC-8 clip). Intuitively I think there should be no problem, but I just don't know this area. Perhaps someone who understands this better, or who has done libreboot flashing could explain this?
