As you can see the output of inxi and the specs listed in the HP website for my laptop show different GPUs, according to HP it is an AMD Radeon R2 Graphics (Stoney Ridge generation - Rx 400 Mobile, according to Techpowerup), while Manjaro detects an AMD Radeon R3 Graphics (Mullins generation - Rx 200 Mobile, according to Techpowerup).
I’m using the open source AMD drivers (video-linux aka radeon) and the only other options given by mhwd are video-modesetting and video-vesa. I have tried both but they result in Manjaro not booting.
I’m at the end of my wits with this, I keep searching for a way to make Manjaro detect the correct GPU but so far nothing… Any help would be really appreciated.
Second … kernel 5.6 is EOL … please upgrade to 5.7 or drop to LTS 5.4 (or both)
Third … I doubt it matters what model inxi is returning to you.
Its an opensource radeon card … it will use the same driver on whatever card it actually is.
In both cases it would be early GCN (1.1,1.2). I think if it were the volcanic card actually it would use the AMDGPU driver rather than the older radeon …
I say check the things above (kernel and BIOS) first then … we might do what we would normally do to load AMDGPU on earlier ‘experimental support’ cards (sea and southern islands +)
My apologies, I know you had already pointed that out but I sincerely thought I had updated to the latest kernel. I used the graphical settings manager to install kernel 5.8 and it shows as running there. I also thought that this line in my inxi output meant I’m running kernel 5.8.1-3, which is the same version number as shown in the graphical settings manager:
[leo@leo-zen ~]$ mhwd -li
> Installed PCI configs:
NAME VERSION FREEDRIVER TYPE
video-linux 2018.05.04 true PCI
Warning: No installed USB configs!
Lets edit a few things: /etc/mkinitcpio.conf on the MODULES line we want it to look like this MODULES=(amdgpu)
And at /etc/default/grub on the GRUB_CMDLINE_LINUX line we want it to look like this (assuming no other options): GRUB_CMDLINE_LINUX="radeon.modeset=0"
Ok, now I get a completely black screen upon boot and I can’t change to a terminal. I’m afraid I don’t know how to get out of this one I suppose we’d use kernel parameters to get to a terminal and undo the changes but I’m not familiar enough with them.
Also, just to be clear, I undid the previous changes to the config files before installing amd-experimental so that Manjaro would boot again. You recommended a reboot from a terminal so I got the impression that you might think Manjaro still wasn’t booting.
I’ve followed the instructions to boot into runlevel 3 as detailed in your post but Manjaro still booted to an unresponsive blackscreen. I’m sure I followed the right procedure because I tried it in another computer with Manjaro and it worked correctly, so since I haven’t moved anything into this install yet I ended up simply reinstalling Manjaro instead to get around the problem.
Any more ideas?
Thank you for your help so far, I’ve learned quite a bit.
I tried it again and got the same result: Manjaro doesn’t boot but upon changing to a TTY the output of inxi -Gazy shows no driver loaded.
I don’t think I made any typo in editing the files according to cscs’ instructions, but here are the contents of the edited files, just in case:
# vim:set ft=sh
# The following modules are loaded before any boot hooks are
# run. Advanced users may wish to specify all system modules
# in this array. For instance:
# MODULES=(piix ide_disk reiserfs)
# This setting includes any additional binaries a given user may
# wish into the CPIO image. This is run last, so it may be used to
# override the actual binaries included by a given hook
# BINARIES are dependency parsed, so you may safely ignore libraries
# This setting is similar to BINARIES above, however, files are added
# as-is and are not parsed in any way. This is useful for config files.
# This is the most important setting in this file. The HOOKS control the
# modules and scripts added to the image, and what happens at boot time.
# Order is important, and it is recommended that you do not change the
# order in which HOOKS are added. Run 'mkinitcpio -H <hook name>' for
# help on a given hook.
# 'base' is _required_ unless you know precisely what you are doing.
# 'udev' is _required_ in order to automatically load modules
# 'filesystems' is _required_ unless you specify your fs modules in MODULES
## This setup specifies all modules in the MODULES setting above.
## No raid, lvm2, or encrypted root is needed.
## This setup will autodetect all modules for your system and should
## work as a sane default
# HOOKS=(base udev autodetect block filesystems)
## This setup will generate a 'full' image which supports most systems.
## No autodetection is done.
# HOOKS=(base udev block filesystems)
## This setup assembles a pata mdadm array with an encrypted root FS.
## Note: See 'mkinitcpio -H mdadm' for more information on raid devices.
# HOOKS=(base udev block mdadm encrypt filesystems)
## This setup loads an lvm2 volume group on a usb device.
# HOOKS=(base udev block lvm2 filesystems)
## NOTE: If you have /usr on a separate partition, you MUST include the
# usr, fsck and shutdown hooks.
HOOKS="base udev autodetect modconf block keyboard keymap filesystems"
# Use this to compress the initramfs image. By default, gzip compression

We did that already (the options would have been added by amdgpu-experimental)
The problem is … the card is sorta recognized as volcanic+ … none of which should need the things anyways … but it still wont load amdgpu properly … if forced (disable radeon) we are still left with black screen.
… maybe … an idea would be to use xorg to load amdgpu.
