Triple-DE Debian System Can't Reach Display Manager
by Mr. Macintosh from LinuxQuestions.org on (#5AJ8R)
I installed Debian Testing yesterday with Plasma, GNOME, and XFCE. I mostly just use Plasma, but I like to play around with GNOME and XFCE sometimes. This is on a new system.
After installing, I removed the installation media as directed, and allowed the system to reboot. After GRUB, I was greeted by a blank screen and a blinking cursor. I thought it was just that I needed to install the graphics drivers and/or firmware, so I switched over to the CLI via CTL+ALT+F2 and tried that - including the Vulkan and OpenCL drivers.. I rebooted and was greeted by the same blinking cusror.
What did I do wrong? In a triple DE configuration like this, which display manager should you choose? GDM? SDDM? LightDM? Or is that not the issue? Could it somehow be a driver issue?
Here are my specs:
Code:MSI B550 Gaming Plus AMD Ryzen 5 5600X Sapphire Pulse RX 5600 XT Corsair Vengeance LPX 16GB (2x8GB) 3200 MHz 1TB WD Blue SN550
Update: I just updated and I got a bunch of error messages about missing GPU firmware, which is weird because I know that I installed firmware-linux-free, firmware-linux-nonfree, and xserver-xorg-video-all. Here are some of those error messages:
Code:Possible missing firmware /lib/firmware/amdgpu/arcturus_gpu_info.bin for module amdgpu
Possible missing firmware /lib/firmware/amdgpu/navy_flounder.ta.bin for module amdgpu
Possible missing firmware /lib/firmware/amdgpu/navyflounder_sdma.bin for module amdgpu
