Hi,

VMD was working perfectly fine until this morning in which it went
completely berserk, and for no aparent reason he refused to work giving me
the following.

Now, my xorg.conf file is

************************************************
Section "Screen"
        Identifier "Default Screen"
        DefaultDepth 24
EndSection

Section "Module"
        Load "glx"
EndSection

Section "Device"
        Identifier "Default Device"
        Driver "fglrx"
EndSection
*************************************************

Any ideas of what may be the problem? I'm completely lost here, specially
because it was working perfectly fine until this morning, and the only out
of the ordinary thing I did was to install alsa-backports last night, but I
can't see how that could be related to a display issue.

Please, can anybody help me?

Thanks in advance.

Diego
