Hi Everyone,

I am encountering a black screen after booting into my desktop environment on Gentoo Linux. The system seems to be booting up normally, but once I reach the point where the desktop should appear, the screen goes black. I can still hear system sounds, but no display shows up.

Here are the details:

Gentoo Version: Gentoo 2024
Desktop Environment: GNOME
Graphics Card: NVIDIA GTX 1650
Log Files: Xorg logs, dmesg output
Steps I Have Tried:

Rebooting
Reinstalling the desktop environment
Updating drivers
Switching to a different display manager (source: [Moderator edit: A commercial link has been deleted - this account will be banned if it is repeated -- pietinger]
Has anyone encountered a similar issue? Any help or troubleshooting suggestions would be greatly appreciated!

romromillys,

there are not actual "Xorg logs and dmesg output" (link or otherwise) in your post.

romromillys,

first of all: Welcome to Gentoo Forums! :D

Do you use our Gentoo distribution kernel or a manually configured kernel?

If the latter is the case, then please read:

Kernel 6.6: https://wiki.gentoo.org/wiki/User:Pietinger/Tutorials/Manual_Configuring_Kernel_Version_6.6#Part_3_-_Must_Haves
Kernel 6.12: https://wiki.gentoo.org/wiki/User:Pietinger/Experimental/Manual_Configuring_Current_Kernel#Framebuffer_Device_and_Console

Otherwise we need more information about your system. Do you know how to chroot back into your installation?

(If not, please read: https://wiki.gentoo.org/wiki/User:Pietinger/New_at_Gentoo#Pause_during_Installation )

Then we need all 3 files mentioned here (also note the reference to “wgetpaste”):

Thanks for pointing that out! I will gather the Xorg logs and dmesg output to help diagnose the black screen [Moderator edit: A commercial link has been deleted - this account will be banned if it is repeated -- pietinger] issue and share them soon.
