configuring a new system, getting Radeon card to work
by dkktav from LinuxQuestions.org on (#5946Z)
[Not actually a newbie, but have been gone since before the 3.0 kernel]
I'm configuring my first Linux system since nearly the start of the millennium, and my first add-in graphics hardware ever. I could use some help.
Kernel: 4.19.0-11-amd64
OS: Debian GNU/Linux 10 (buster)
Graphics card: Sapphire Pulse Radeon RX 5500 XT
Motherboard: TUF Gaming x570-plus
CPU: Ryzen 7 3700x
I've re-installed the system using the most generic/newbie options and gotten the same result as in my previous attempts: The graphics work during installation but not after.
/var/log/Xorg.0.log shows Radeon configuration, then:
(II) modesetting: Driver for Modesetting Kernel Drivers: kms
(II) FBDEV: driver for framebuffer: fbdev
(II) VESA: driver for VESA chipsets: vesa
(EE) open /dev/dri/card0: No such file or directory
(WW) Falling back to old probe method for modesetting
(EE) open /dev/dri/card0: No such file or directory
(II) Loading sub module "fbdevhw"
(II) LoadModule: "fbdevhw"
I haven't found nomodeset anywhere, which seems to be the most common cause for this error. But perhaps I'm just not looking in the right place. The string "nomodeset" isn't in /etc/default/grub or in /etc/default/grub.d/*
The default install gave me the linux-firmware-free package, and I thought I wouldn't need the nonfree for an AMD graphics card (which is why I bought this one rather than an NVIDIA). During a previous install I tried the non-free firmware, but that didn't seem to help (but maybe I just didn't reboot enough).
As far as I know I've done nothing out of the ordinary in this installation. (I'm waiting until I have this resolved before returning to my intended setup.) So this should be just a matter of what hardware I have (see above, starting with "Kernel:") and the most-standard Debian distribution in its most-standard configuration.
