mga6 sta1 - Virtualbox - X Fails to Start For Some Desktops

[ca-on-adam]

Hello,

Under virtualbox, I installed from the classic 32bit DVD. After the reboot, I got a text-only screen that said there was a problem starting the Graphical Session. It said to run drakx11, and I did, but none of the options seemed likely to produce a fix, and the "Test" button returned EE errors from the X server.

Here is the Xorg.0.log after trying drakx11:

This was a 32bit MATE desktop install. I haven't seen if other desktop choices have this same problem or not.

EDIT: I tried another install selecting the LXDE desktop: and exactly the same problem occured. So this appears to affect any 32bit install.

Hello ca-on-adam,

Have you installed Oracle virtual box extensions? [ https://www.virtualbox.org/wiki/Downloads ]

edit: you may need to reboot afterwards

[janpihlgren]

Hi
I think you get the same problem I get in the beginning of July. The error depends on to early/fast update of Mageia 6 sta1 after the that the repository was updated.
I reported it as bug 18892 and get the advice to wait so the repository will be updated.
I get the same error today.
This time I have to do a clean installation followed by an update.
My advise is to restore a backup and wait one day before update.

Hello ca-on-adam,

Have you installed Oracle virtual box extensions? [ https://www.virtualbox.org/wiki/Downloads ]

edit: you may need to reboot afterwards

I have never needed the virtualbox extensions, and I have installed many many Linux guests under virtualbox with success. The extensions are not related to the X server. This will not fix the problem.

Oracle VM VirtualBox Extension Pack:
Support for USB 2.0 and USB 3.0 devices, VirtualBox RDP and PXE boot for Intel cards.

Same here.

This is correct.

How-ever I had a very very similar problem a few days ago.
drakx11 was unable to determine a valid configuration.
I also attempted other forms of correction.
In a final "what have I got to loose", adding extensions fixed the problem for me.
I may have rebooted at this time
I then reinstalled the guest Mga6 system without issue
(I use Mga5 x86_64 as host)

I just did a full update with "Core Updates" and "Nonfree Updates" enabled. It did not fix the problem.

I will try this if no other solutions are found. I really don't like this solution because the 64-bit version works fine without installing that pack on the host, therefore this 32-bit version should work too.

If installing VB extensions corrects the issue for you,

please append https://bugs.mageia.org/show_bug.cgi?id=19032, and change to "re-opened".
add your Xorg.0.log to the bug also.


thank you

How usb support pack can fix xorg fails to start problem ? that's should not be possible.

this I do not know.

however the extension pack also adds VirtualBox RDP support.

[doktor5000]

however the extension pack also adds VirtualBox RDP support.

And how is RDP support for virtualbox related to your X server ?

[ca-on-adam]

I have found a workaround as mentioned in https://bugs.mageia.org/show_bug.cgi?id=18917.

I created a file /etc/modprobe.d/vboxvideo.conf with the contents "blacklist vboxvideo", then rebooted.

It seems that there are two entities called vboxvideo, one is a kernel module (lowercase) and one is an X.org driver (VBoxVideo with capitals). When the kernel module vboxvideo is loaded, X fails to load VBoxVideo, and then fails to find a screen. I'm not sure what the fix is to this problem.

And I did not need to install Virtualbox Extensions.




EDIT: I just installed another 64-bit guest (with MATE desktop instead of KDE), and had this problem. So it affects 32-bit and 64-bit guests. The choice of desktop seems to determine whether the problem occurs.

Exactly i wan't to know it too.

Problem is with old deprecated xorg.conf i removed it and then xorg started without errors.

As a matter of fact, now xorg.conf is deprecated

http://www.linuxquestions.org/questions ... 175497699/

Mageia should think to move to /etc/X11/xorg.conf.d/*-.conf files what is readed first then old xorg.conf,it works but not supported officially anymore.

Feel free to send patches.

[morgano]

...and/or put in errata and/or please add this info to https://wiki.mageia.org/en/VirtualBox#On_guests

[doktor5000]

That suggestion goes to whom? And you're aware the wiki can be edited by anyone with an identity.mageia.org account?

[morgano]

I meant to suggest the one with fresh view on the subject to share.
(Yes and i have both created and edited articles, while i was dealing with a subject and felt i had a fresh view of it, i.e owncloud.)
