Description of problem: After an apprently successfull installation of MGA10 alpha1, I only can start the instance on run level 2. All "startx"s commands fail for all DE's installed (Plasma, Xfce4, MATE and Icewm) Version-Release number of selected component (if applicable): MGA10 alpha1 How reproducible: Allways. This problem occurred also in the backport installation of kernel 6.12.60 in MGA9, except that there MATE worked OK, Plasma and Xfce4 did not.

I think your issue is similiar to mine https://bugs.mageia.org/show_bug.cgi?id=34846 Please in recovery mode run drakx11 and set modesettings as video driver

Why you don't try the live plasma instead?

See the riseup pad: that works. That is why I have to wipe it out and start over again to do what Comment 2 asks.
Installed m10 afresh on Compaq laptop, followed instructions in Comment 2 and rebooted, with the normal boot: hangs again , X does not start.
Look like your system have other issue Other thing you can try is remove or rename /etc/X11/xorg.conf
You mean like: boot in recovery mode rename /etc/X11/xorg.conf to /etc/X11/xorg.conf.20251216 run drakx11 reboot normally. Result: nihil as far as X server is concerned.

I think he means rename or discard /etc/X11/xorg.conf, then start in a configuration where there isn't any xorg.conf file (so don't run drakx11 later), not clean xorg.conf and recreate. Also if that doesn't work try with passing: radeon.si_support=1 radeon.cik_support=1 amdgpu.si_support=0 amdgpu.cik_support=0 or radeon.si_support=0 radeon.cik_support=0 amdgpu.si_support=1 amdgpu.cik_support=1 at boot cmdline.
First try: boot in recovery mode remove /etc/X11/xorg.conf reboot Noppes, nihil, niente, no X server. Second try: First option to add to boot cmdline (painfull as this involves typing QWERTY on an AZERTY keyboard) that made it! Tried both xfce4 as plasma, seems to work OK.
Assigning to you, Giuseppe, as you are already onto it.

Tested again on round2: adding radeon.si_support=1 radeon.cik_support=1 amdgpu.si_support=0 amdgpu.cik_support=0 to command line has no result now.
So it works or doesn't anymore?
The first option does not work anymore, but the second does (didn't use that on in round1. Now, using grub2, where can I edit that command line so it is permanent for this instance???
/etc/default/grub for adding (line GRUB_CMDLINE_LINUX_DEFAULT) then updating the config with update-grub2. The config that works are with amdgpu or radeon as kernel module? And which entry in /etc/X11/xorg.conf if used? Does it work with modesetting and does it work with no /etc/X11/xorg.conf file at all?
In /etc/X11/xorg.conf I see driver "amdgpu". I tried before with no /etc/X11/xorg.conf file, but that did not improve the situation. kernel module??? No idea how to get there. And one more question: does changing the /etc/default/grub impact only this particular instance, or all (I have two other M9 parttitions) on the laptop.

And in /etc/X11/xorg.conf the Device section when it's working is using Driver "amdgpu" or "radeon"? or "modesetting"?
Added the line in /etc/default/grub and run update-grub2. As I suspected/feared this reported: Found M10 on sdax Found M9 on sday Found M9 on sdaz and then completed. Rebooted and checked the command lines: only one of the M9 instances has the assignments, not the other M9, not the M10. Booting the M10 of course then does not start X server. Grub 2 has aiisues when too many kernal modules are found on the machine, it looks like this is another one. I will try refind but getting rid of grub is another matter.

That said, all four options are expected to become invalid post-6.17 kernels or sooner, with amdgpu module becoming preferred over radeon by default. With various distros and post-6.12 kernels I've been finding need to omit one or both for KMS to function, or completely non-functional KMS with or without them.
