Re: Black screen during boot with a new monitor

"/sys/class/drm/card1-HDMI-A-1" does not exist here.

$ ls /sys/class/drm
card0  card0-DP-1  card0-HDMI-A-1  card0-HDMI-A-2  card0-HDMI-A-3  card0-VGA-1  renderD128  version

I have tried this:

$ sudo cp /sys/class/drm/card0-HDMI-A-1 /usr/lib/firmware/edid/GA25FC.bin
cp: -r not specified; omitting directory '/sys/class/drm/card0-HDMI-A-1'

Then this:

$ sudo cp -r /sys/class/drm/card0-HDMI-A-1 /usr/lib/firmware/edid/GA25FC.bin

After reboot, again I see error in dmesg:

Re: Black screen during boot with a new monitor

You don't have to post that - errno 2 means the file wasn't copied there itfp. the error would have shown up then

ls -lR /usr/lib/firmware/edid/

Re: Black screen during boot with a new monitor

Do you have i915 in the initramfs? You'll have to add the edid there as well (as the wiki mentions)

Re: Black screen during boot with a new monitor

i915 was already present, I have just added the EDID to "FILES()" in /etc/mkinitcpio.conf, ran "sudo mkinitcpio -p linux", rebooted, no error related to edid in dmesg this time... but still black screen.

Re: Black screen during boot with a new monitor

I have tested some Linux systems again, with live USBs created individually this time, without Ventoy, with these results:

CachyOS - I do not see black screen like Arch
EndeavourOS - Black screen like Arch
Fedora KDE 43 - the screen is not black during most boot process
PopOS - the screen is not black, I see plymouth boot screen
neon unstable (based on ubuntu 24.04): black screen in different moments, possibly due to buggy plymouth

I have also removed GRUB from the SSD where I have both Arch and Windows 10 installed
by running "bootrec /fixmbr" command from Windows. And, without GRUB, I see the Windows logo
during almost entire boot process. The screen gets black ~2 seconds before the login screen.

Seems GRUB installed on my Arch is someway causing the black screen during boot with this new monitor.

And there is something wrong with the EDID of my monitor, "EDID conformity: FAIL":

Re: Black screen during boot with a new monitor

Seems GRUB installed on my Arch is someway causing the black screen during boot with this new monitor.

Re: Black screen during boot with a new monitor

GRUB config before this comment:

$ cat /etc/default/grub
# GRUB boot loader configuration

GRUB_DEFAULT=saved
GRUB_SAVEDEFAULT=true
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="Arch"
GRUB_CMDLINE_LINUX_DEFAULT="scsi_mod.use_blk_mq=1 mitigations=off pcie_aspm=off nowatchdog no_console_suspend initcall_blacklist=simpledrm_platform_driver_init drm.edid_firmware=HDMI-A-1:edid/GA25FC.bin"
GRUB_CMDLINE_LINUX=""
GRUB_DISABLE_OS_PROBER=false

# Preload both GPT and MBR modules so that they are not missed
GRUB_PRELOAD_MODULES="part_gpt part_msdos"

# Uncomment to enable booting from LUKS encrypted devices
#GRUB_ENABLE_CRYPTODISK=y

# Uncomment to enable Hidden Menu, and optionally hide the timeout count
#GRUB_HIDDEN_TIMEOUT=5
#GRUB_HIDDEN_TIMEOUT_QUIET=true

# Uncomment to use basic console
GRUB_TERMINAL_INPUT=console

# Uncomment to disable graphical terminal
#GRUB_TERMINAL_OUTPUT=console


# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
GRUB_GFXMODE=auto

# Uncomment to allow the kernel use the same resolution used by grub
GRUB_GFXPAYLOAD_LINUX=keep

# Uncomment if you want GRUB to pass to the Linux kernel the old parameter
# format "root=/dev/xxx" instead of "root=/dev/disk/by-uuid/xxx"
#GRUB_DISABLE_LINUX_UUID=true

# Uncomment to disable generation of recovery mode menu entries
GRUB_DISABLE_RECOVERY=true

# Uncomment and set to the desired menu colors.  Used by normal and wallpaper
# modes only.  Entries specified as foreground/background.
#GRUB_COLOR_NORMAL="light-blue/black"
#GRUB_COLOR_HIGHLIGHT="light-cyan/blue"

# Uncomment one of them for the gfx desired, a image background or a gfxtheme
#GRUB_BACKGROUND="/path/to/wallpaper"
#GRUB_THEME="/path/to/gfxtheme"

# Uncomment to get a beep at GRUB start
#GRUB_INIT_TUNE="480 440 1"

# Uncomment to make GRUB remember the last selection. This requires to
# set 'GRUB_DEFAULT=saved' above.
#GRUB_SAVEDEFAULT="true"
GRUB_DISABLE_SUBMENU=n

I have modified these lines:

GRUB_TERMINAL_OUTPUT="gfxterm"
GRUB_GFXMODE=1024x768x24

Updated the grub config, rebooted, and the black screen persists.

Re: Black screen during boot with a new monitor

As I wrote in comment 19, I already tried to disable the framebuffer. I tried it again before my previous comment; the black screen persists.
