Description miguel ajaoud 2020-09-27 15:09:07 CEST

Hello everyone,
First of all, thanks in advance for your attention.
This is my first time reporting a problem, and I do it because I'm going crazy :(
I've been the whole weekend reading another cases, but I'm unable to fix this.

I have a machine with Mageia 6 installed, and a display

$ uname -a
Linux ybts-cpgknf8e 4.14.89-desktop-1.mga6 #1 SMP Mon Dec 17 13:14:48 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

I must say that everything was ok, until I installed TigerVNC (and I guess another packages)

But now when I power on the machine theres a message that says:

***
Display driver issue
Detected a loaded display driver kernel module which conflicts whit the driver the X server is configured to use. Startup of the X server may now fail.
<OK>
***

Then, it appears the famous "Good luck message":
***
Sorry, but there has been a problem starting your graphical display.
In order to debug your problem we will automatically switch to a text-based login screen from where you can login as the root user and run the 'drakx11' utility to configure your graphical display.
After configuration, you can restart your graphical environmetn via the command: systemctl default
at which point you will be automatically logged out while the graphical system starts.
If you would prefer to avoid this message and go straight to a text-based login system at boot, simply change the symlink /etc/systemd/system/defaul.target to point instead to /lib/systemd/system/multi-user.target
Good luck :)
Press any key
***

I've run drakx11 a thousend times
Same with drakcomand
I've tried to install the drivers, and there's no way.

There's something I think is important, and...

If in the machine I run xclock, or xrandr...

Error: Can't open display

BUT! If with my laptop (house network)
I connect to the machine (ssh)
and I run xclock, or xrandr...
There is a display detected:
***
$ xrandr
Screen 0: minimum 0 x 0, current 1536 x 864, maximum 32768 x 32768
default connected primary 1
$ echo $DISPLAY
localhost:10.0

meanwhile in my machine... this is not happening...

Actually, I run drakconf from my laptop, so at least, the Mageia Control Center is opened in my laptop.

Is this a problema of the X server?

How can I configure the machine, to get the Display detected? Is it a problem of the driver?

I haven't seen anything rare in Xorg.cong

Thanks and regards!

Hi, thanks taking time reporting this.

Mageia 6 is end-of-Life and we can't provide updated packages for this version of our distribution.
As we see you're running a x86_64 system, I recommend you to upgrade your system to Mageia 7.1 with the classic ISO installer and adding online repositories.


We should close this bug INVALID but we will provide you some help. We need to know what is your graphic card in order to see which driver is best suitable to it.

Meanwhile, I recommend to add "nomodeset" or "nokmsboot" to kernel command-line before booting.

Hi.
I would appreciate it.

Thanks a lot!

Finally I have changed the nokmsboot option to nomodeset in the boot options.

It works!

Thanks a lot!

Yeah, but I must pinpoint you that you're running a End-of-Life distribution (Mageia 6).
Furthermore, you're CPU is a 8th generation Intel Core processor which not supported by your 4.14.89-desktop-1 Kernel and x11-driver-video-intel's version in M6.
You must upgrade, that why DrakX11 (XFDrake) can't set it correctly, and that why at least put "nomodeset" to Kernel command line prevent your system to use correct driver configuration and 3D acceleration in Intel driver is deactivated.

We close this WONTFIX (EOL).
