[SOLVED] blackscreen after boot kernel message,

double_crane · Last edited by double_crane on Wed Jan 25, 2023 7:01 pm; edited 4 times in total

My computer is MSI MOTAR B450 + AMD R5 3600 + Nvidia 1060, kernel 5.15.59, BIOS(not UEFI), Gnome3
nearly I did a "emerge update deep new world", the last time I did the update is 3-6 months ago.

after this update, I find that after power on, bios info, GRUB menu, and console boot message, all seems well,
but when it's the time that desktop should appear, there's no signal on HDMI and screen turn to 'black and sleep mode'.

I try to login even though I can't see the desktop, and try execute some command such as "dmesg > ~/dmesg.log",
I find it works. I can see the dmesg.log on the harddisk when I boot a ubuntu usb livecd.

I try update the kernel to 5.15.88 and do "emerge -e world", but no use, still blackscreen after boot.
I try systemctl disable gdm, but still blackscreen. no character console.

here is my dmesg log and KERNEL CONFIG. Any help? thanks.

there's no new /var/log/Xorg.0.log file generated after I remove the old one.
dmesg file: http://double-crane.imzone.in/gentooforum/dmesg.txt
KERNEL CONFIG: http://double-crane.imzone.in/gentooforum/config.txt

how to upload the attachments? always get "error in posting"

KERNEL CONFIG_FB_VESA/SIMPLE/EFI are all selected according to nvidia driver's hint.

double_crane,

Use wgetpaste to put the files onto a pastebin site and post links.
Helpers will quote the interesting bits so that they are not lost.

When does to screen go blank?
After grub, when the kernel loads?
After the kernel messages as the desktop starts?

double_crane,

That helps.

Pastebin those two files and your /var/log/Xorg.0.log file please.
