[SOLVED] Unable to start xwindows with Radeon RX480

bocabits · 05-11-2022, 08:58 AM

Hello;

I have just upgraded my box with a Radeon RX480 card and I have not been able to start KDM. I think the drivers are installed ok (I've used the Ubuntu link from https://www.amd.com/es/support/previ.../radeon-rx-480). The card works in Windows. The monitor is a LG 24MP400.

When the computer boots it stalls starting the session manager. If I try the autogenerated file the screen goes black and I have to reboot the computer with the botton.

you do not need to generate that config, it should work without that. rx480 works perfectly on linux.

Arnulf · 05-11-2022, 02:00 PM

Boot into a console without loading X and post the output of dmesg.

Thanks Arnulf. I have uploaded the dmesg output to this url: https://pastebin.com/Vb9jQHWV

When I start the computer, the boot sequence stops here: https://i.imgur.com/Cs6WYOl.jpg

pan64 · 05-12-2022, 12:13 AM

again, your generated conf file is incorrect. That's why it is stopped:

Code:

[    12.172] Data incomplete in file /etc/X11/xorg.conf
	Undefined Screen "Screen1" referenced by ServerLayout "X.org Configured".
[    12.172] (EE) Problem parsing the config file
[    12.172] (EE) Error parsing the config file

Just remove that file and try to boot and start X again. Probably it will just work without that.
From the other hand you need to post the mentioned log file (after fixing or removing that conf file).

Upgraded from what? Are xserver-xorg-video-amdgpu and firmware-amd-graphics installed? If they are installed, and /etc/X11/xorg.conf does not exist, and there is no residue from having had NVidia drivers installed and incompletely purged, X should just work automatically.

bocabits · 05-12-2022, 03:21 AM

The issue has been solved by removing the /etc/X11/xorg.conf file.

Thanks to all for your help.

Arnulf · 05-12-2022, 01:49 PM

dmesg output shows some ACPI errors. Check for an UEFI update and install it.

bocabits · 03-23-2023, 05:43 PM

Hello, this is me with the same issue. Again.

My motherboard crashed so I replaced it with an ASUS Prime B550MK but kept most of my components including the Radeon RX 400 graphic controller. I've installed Debian 11 and I can't get KDM to start. When the system boots, the screen remains black with a cursor blinking on the left upper corner.

I have installed the official driver from ATI and get this message

Thanks a lot for any ideas or help.

If you hadn't installed proprietary software you shouldn't need, I would have suggested after your cursor has been on black screen a minute or more, from a vtty login prompt, instead of startx, try systemctl restart gdm.

AMD does a really good job of making the drivers in standard distro repos work well, but sometimes cmdline options are required as workarounds for known issues.

GDM is the worst possible choice for getting Plasma to work. Plasma really isn't ready for Wayland yet. Try LightDM, SDDM, XDM or TDM instead of GDM for running KDE, and for an X11 session, not Wayland, and purge the non-standard drivers. For some use cases they are an upgrade from working drivers, but they are not a replacement for non-working drivers, as are NVidia's.

pan64 · 03-24-2023, 02:10 AM

https://wiki.archlinux.org/title/SDDM
(this is a bit offtopic here)
That is an interesting issue, gdm for gnome and kdm for kde, and that was an obvious choice long time ago. They're still not interchangeable these days, but in theory they should be. LightDM is a good choice too.

bocabits · 03-24-2023, 04:03 AM

I have removed gdm3. This is what happens after booting.

Personally, I always try to simplify things: try getting xorg to run first and don't put a display manager in the mix until you successfully get xorg running.

I have reinstalled debian and KDE (from the debian installer). No ATI official driver this time. Apparently sddm works fine, but I get no login screen and have to open a console and run startx to get KDE.

To find out why we need to see Xorg.0.log pastebin'd (pastebinit /var/log/Xorg.0.log) and input/output from inxi -Gaz run from within Konsole, after first removing B_ALLOW_UPDATE=false from /etc/inxi.conf and then running inxi -U as root or with sudo.
