Cannot get into X with ati drivers - Failed to open DRM device

genji · 2023-09-25 02:41:47

Hello all, trying to use Arch an old box of mine and was following the wiki as best as possible, but have encountered an issue during anything actually calling the X server like sddm or startx ( https://wiki.archlinux.org/title/xorg )

[genji@arch ~]$ sudo lspci -v | grep -A1 -e VGA -e 3D
lspci: Unable to load libkmod resources: error -2
02:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Cedar [Radeon HD 5000/6000/7350/8350 Series] (prog-if 00 [VGA controller])
        Subsystem: Hightech Information System Ltd. Cedar [Radeon HD 5000/6000/7350/8350 Series]

I installed xf86-video-ati after xf86-video-amdgpu did not seem to work. This is an older machine from the earlier 2010's

Here is the Xorg.log as required: http://ix.io/4Hmj

I thank you as always for your help

[1864825.525] (EE) open /dev/dri/card0: No such file or directory

And lspci doesn't show whether or which driver is loaded (don't grep and if you need to grep, grep -A3) but "Unable to load libkmod resources: error -2" what likely means you're booting a dated kernel "BOOT_IMAGE=/boot/vmlinuz-6.2.16-3-pve"

pacman -Qs kernel
cat /proc/cmdline

Hi seth, thanks for getting back to me as always, you seem to be by far the helpful one on this forum, it is much appreciated

Sorry, I used the grep command as listed above because it was a direct copy & paste from the Arch instructions

Here is the ungrepped output: http://ix.io/4Hpn

[root@arch ~]# pacman -Qs kernel
local/iptables 1:1.8.9-1
    Linux kernel packet control tool (using legacy interface)
local/kmod 30-3
    Linux kernel module management tools and library
local/libdrm 2.4.116-1
    Userspace interface to kernel DRM services
local/libnetfilter_conntrack 1.0.9-1
    Library providing an API to the in-kernel connection tracking state table
local/libnfnetlink 1.0.2-1
    Low-level library for netfilter related kernel/userspace communication
local/libsysprof-capture 3.48.0-4
    Kernel based performance profiler - capture library
local/linux-api-headers 6.4-1
    Kernel headers sanitized for use in userspace
local/mtdev 1.1.6-2
    A stand-alone library which transforms all variants of kernel MT events to the slotted type B protocol

[root@arch ~]# cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-6.2.16-3-pve root=/dev/mapper/pve-root ro quiet

As far as outdated goes - highly possible - I am using a file called archlinux_base_20230608-1_amd64.tar which I guess would imply by the datecode a few months old ? And I got this just directly from Proxmox using their built in Template downloader - I am unsure if there's a better & more updated way to go about it?

Thank you seth

So this isn't Arch at all. That's a problem, yes.

The radeon driver seems loaded but you installed the kernel outside the package management.
Please post your complete system journal for the boot:

sudo journalctl -b | curl -F 'file=@-' 0x0.st

However, afaiu this is an archlinux container on a proxmox system?
As Scimmia pointed out, that gets you at odds w/ the forum rules but will most likely also be the reason for the DRM failure.
Idk. whether graphical environment is supposed to work this way, in doubt you'll have to use xf86-video-{vesa,fbdev}
