recently I got myself a new Radeon RX 6800 (Power Color Red Devil, Silent BIOS). Searching the web I saw, that it should be supported by Linux, so I made a fresh install of the latest Manjaro (Nibia).
Unfotunately, there is only a black screen with a cursor after booting.
Using Strg+Alt+F2 I switched to tty and upgraded the Kernel from 5.9 to 5.10, but there is still a black screen. Mesa 20.3 is installed. I have no idea, what the problem is.
Is this new graphics card not supported? I thought that an up-to-date Kernel and Mesa would be sufficient. Do I have to wait for the next official Manjaro release?
My other hardware is:
Gigabyte B550 Aorus Pro V2
Ryzen 9 3900X
Graphics: Device-1: AMD vendor: Tul driver: amdgpu v:kernes bus ID: 0b:00.0 chip ID: 1002:73bf Display: server: Xorg 1.20.10 driver: ati,radeon unloaded: modesetting alternate: fbdev, vesa tty: 240x67 Message: Advanced graphics data unavailable in console. Try -G --display
Your second command gives alot of text and the following error (I believe):
Using config directory: “/etc/X11/xorg.conf.d” Using system config directory: “/usr/share/X11/xorg.conf.d” Couldn’t exec xterm: No such file or directory xinit: connection to X server lost waiting for X server to shut down (II) Server terminated successfully(0).
What does that mean? The driver should be there but xserver/xterm is not installed properly? Besides the newer kernel I did not change anything after the fresh Manjaro install.
sudo systemcrtl restart lightdm.service
got me to the login and Desktop!
But after a computer-restart I end up in the black screen with blinking cursor again. So it seems, that I would have to restart the service after every boot. What is wrong with my installation or hardware?
PS: sudo systemctl isolate graphical.target also got me into Login and Desktop. The default target for systemctl is already the graphical target. Still, I have to type this on every boot…
I think I was able to fix it and it could be helpful for some people. This is the info from the ArchWiki about LightDM:
It may happen that your system boots so fast that LightDM service is started before your graphics drivers are properly loaded. If this is your case, you will want to add the following config to your lightdm.conf file:
This command indeed helped me booting through to the login. Thank You very much pobrn for Your help and patience!
