[SOLVED] I screwed up xserver settings

Recetly upgraded a Giada box with nvidia ION graphics to Mageia 4. Video worked more or less ok. After playing around with x-server settings with drak-conf tthe box does not show video anymore after the first splash screen. It is stuck untill an error message shows up without any explanation of the nature of the problem. It does not continue to the GRUB login graphical user interface. However it's possible to login with a command console.
Is there a way to reset the settings for xserver to some default values using the command console?
I would greately appreciate any help.

try to run

Code: Select all
drakx11


the default values it propose are the supposed best settings for your card,
but sometimes it is better to choose xorg-vesa to have a safe X restart.

Or simply move away/rename or delete /etc/X11/xorg.conf, so that X server will dynamically detect everything, that's the default.

Now I at least can see the boot messages. They indicate that the system fails to start x.
The last message is:
[ok] Reached target Graphical interface.

Seems very similar to this bug: https://bugs.mageia.org/show_bug.cgi?id=13547

Then fix like described in https://bugs.mageia.org/show_bug.cgi?id=13547#c21 or viewtopic.php?f=23&t=7907
Or select another graphics driver.

Ok now fixed the way suggested in
viewtopic.php?f=23&t=7907
urpme -a nvidia
urpmi nvidia
And then by trial and error select a suitable driver which was not obvious for ION2
Thanks!
