Bug Description

This is the error I get before X dumps me to shell. I will attach xorg.conf in a comment.

Also first think I did was run
dpkg-reconfigure xserver-xorg and it still did not work. Attached is the xorg.conf generated by dpkg-reconfigure.

I should also add, I get the same error trying to use vesa.

I figured out a fix. I had to add

Section "Module"
   Disable "dri"
EndSection

to xorg.conf.

Then everything works fine.

Could you please attach /var/log/Xorg.0.log?

Have you previously been using some proprietary drivers, like nvidia or fglrx?

I have not used any proprietary drivers. It is a quite old laptop
and the graphics card is not really capable of any real 3d acceleration.
I have attached the Xorg.0.log produced with dri disabled.

Also I will attach the Xorg.0.log.old produced without disabling dri, (where X doesn't start).

Can you try to run a live CD, in order to verify that this is not an upgrade issue?

Try also:
 ldd /usr/lib/xorg/modules/extensions/libdri.so|grep drm

And:

ldd /usr/lib/xorg/modules/extensions/libdri.so | grep drm

gives

libdrm.so.2 => /usr/local/lib/libdrm.so.2 (0xb7f90000)

locate libdrm.so

gives

/usr/X11R6/lib/modules/linux/libdrm.so
/usr/X11R6/lib/modules/linux/dri-old.libdrm.so
/usr/lib/libdrm.so.2
/usr/lib/libdrm.so.2.3.0
/usr/lib/libdrm.so
/usr/local/lib/libdrm.so.2.0.0
/usr/local/lib/libdrm.so.2
/usr/local/lib/libdrm.so

I decided to also check that

readelf -s /usr/lib/xorg/modules/extensions/libdri.so | grep drmSetServerInfo
gives

30: 00000000 25 FUNC GLOBAL DEFAULT UND drmSetServerInfo
122: 00000000 25 FUNC GLOBAL DEFAULT UND drmSetServerInfo

readelf -s /usr/local/lib/libdrm.so.2 | grep drmSetServerInfo
 finds nothing.

However

readelf -s /usr/lib/libdrm.so.2 gives
100: 000027c0 25 FUNC GLOBAL DEFAULT 11 drmSetServerInfo

So I'm guessing its linked against an older libdrm that was on my system perhaps?

I'll try to do the livecd tomorrow.

Yes, that stuff in /usr/local is something you have installed yourself. Just remove it.

Upon removing that stuff things work fine without disabling dri. Sorry about that.
