*ERROR* Radeon kernel modesetting for R600 or later requires

#1 Post by aindriu »

Hi,

I tried installing Debian on an old Dell Precision T1700 and Radeon Firepro 2270 graphics, the installation went fine and booted to the Grub but I then get the following error:

*ERROR* radeon kernel modesetting for r600 or later requires firmware installed

How can I get around this? I can't get access to a terminal in recovery mode

Installing firmware-amd-graphics should help.

Hi,

Thanks for the help, I changed the bios video from Radeon to Auto, it progressed the boot sequence till GNOME Display Error

I had some trouble even getting to the command line, I used the USB stick to boot into recovery and ran

Code: Select all

sudo apt install firmware-amd-graphics
but it didn't make any difference,. Im getting this screen

I edited /etc/gdm3/daemon.conf and removed the # before WaylandEnables=false

It eventually booted to the login screen :)

Once the screen appeared with the green bracketed OK that GDM loaded you could have logged in from the console as your user.

I'm not seeing any confirmation that your install command for the firmware actually worked. Let's check--show us the output for

Code: Select all

apt policy firmware-amd-graphics

I'm using Sempron 2600+ and Radeon HD 3450 and I got the message "Radeon kernel modesetting for R600 or later requires firmware installed". I installed Debian 11 i386 and the default desktop and LXQT. The start screen where the services get started and finished got stuck when it came to the Simple Desktop Display Manager. After pressing CTRL+ALT+F2, I got to a bash prompt, entered a username and password. Then in the sources list, I added the non-free and contrib keywords. I did apt update, and installed

Code: Select all

firmware-linux-nonfree
After that, I rebooted and the screen got blocked showing white lines, like in the second image.
With a previous installation of the same version, I selected Mate and logged successfully. The resolution was pixelated and low and I couldn't find options to change the video card settings. I installed

Code: Select all

firmware-amd-graphics
and after a reboot, the same white lines block appeared.
Using amd64, the white lines appear immediately, without installing the firmware.

I tried antiX Linux, and the white lines appear too, but when I select either video safe mode with the keyword

Code: Select all

xorg=safe
or another mode with the keyword

Code: Select all

failsafe
then it logs and I can use the OS, but the resolution is pixelated again.
