i don’t know if it caused an manjaro software update or the bios uptate, but the solution I found contains a few things I didn’t find in the old forum posts
Short description:
Intel onboard and later AMD/ATI Radeon RX470
lightdm and x-server are faulty (systemctl)
x-server did not work because no displays were detected
AMD/ATI Radeon RX470 graphic card physically removed from the PC, no improvement
tried ssd on another PC with intel graphics, same error
back in the original PC, AMD graphics re-installed physical
under
/etx/X11/xorg.conf.d
at least the file
90-mhwd.conf
have to delete to have again a graphical system
I had made tests with terminal command and this means the file is missing, so I copy it after my solution again in this path, but the x-server could not run with it and in terminal mhwd does not create a new, maybe I’m using the mhwd command incorrectly
at first I thought this is my actual solution, creating a unit for systemd in the folder: /lib/systemd/system
xorg.service
[Unit]
Description=X Server
After=network.target
[Service]
User=root
ExecStart=/usr/bin/Xorg
Restart=always
[Install]
WantedBy=multi-user.target
This file contains usually instructions for nvidia and yes, it will block the graphical boot when no nvidia card or nvidia driver is found. I read in your profile that you had an Intel+Nivida setup and not Intel+AMD. So the switch must have caused the problem. Mhwd doesn’t remove the config in /etc/X11/ by removing the mhwd-config itself.
This would confuse everyone, no matter how much experience you have… update your OS, wait 2-4 days to get sure the OS is fine and then update your Bios.
the bios update to uefi was due to the intention to install Windows 11 for a specific application, but I rejected it;
after the bios update, I imagine that the manjaro worked quite normally;
the manjaro has only the purpose to realize audio recordings, I do not carry out updates so often, because I actually want to avoid problems;
but recently I switched from the other PC (manjaro KDE) to the manjaro Cinnamon PC because of a bug in LibreOffice Writer, on which FreeOffice did not have the bug; on the day I did the update and actually thought that I also did a reboot to be sure that it works; but I’m not sure about that
i sold the nvidia graphics card about a month after my last post about it and got one from AMD for it; i made benchmarks to compare the 2 cards; the PC definitely worked afterwards even without diue nvidia, with the AMD and the Intel onboard; what plays a role here is what is set in the bios, which variant then takes effect in Linux; i had installed the AMD graphics card back in the last time;
“Mhwd doesn’t remove the config in /etc/X11/ by removing the mhwd-config itself.”
this would mean that once you have installed an nvidia, the other graphics variants will no longer work, unless you personally delete the config file; yes OK, but the hint from you is still worth gold
That will be a problem.
You should remove this post-haste.
And probably force reinstall the ‘group’ open driver profile.
( You should also remove everything else you did … like the extra services, any other test configs, and dont mess with the mhwd file again unless you manually edited it … in which case remove it before reinstalling the drivers. Put everything back the way it was. )
troubleshooting was more important to me than reinstalling;
I will do what you wrote, only I need to know which config files I need to delete – the system does not run with “90-mhwd.conf”, the file is currently deleted or moved to another location;
Should I also delete the “xorg.service” file that I created myself? That would crash the x-server again. i’d better wait with that.
But, thank you very much !!!
Im pretty sure just about everything is related to having vesa installed.
So yes, I do suggest removing whatever you created.
The 90-mhwd file will be recreated in the above steps when reinstalling video-linux.
But with vesa removed I dont think you will have the same issues.
but one more question, I had the graphics drivers and lightdm and x-server all deninstalled, then the /lib/systemd/system
“xorg.service” file, then executed the systemd commands, only then the x server ran again, see my first post;
theoretically, the mhwd command would have done this after deleting the 90-mhwd.conf and removing the vesa drivers also done? because I used pacman to install
I somehow missed that; too close to drinking-up time and getting those stools up and curtains shut, and probably also being snuggled by one of the Pub cats.
This does not look like a good approach.
I remember (when on Ubuntu-base years ago) that APT bug which took out loads of stuff like this; reinstalled the missing stuff using the logs I’d saved as reference for what to put back.
