xubuntu-users - How to diagnose loss of X/GUI after latest kernel upgrade in 8.10?

I just did the latest kernel upgrade on my xubuntu 8.10 system (to
kernel (to 2.6.27-14) and now the X GUI doesn't start up.

I still have virtual consoles working (fortunately, I'm mailing from
one) so most of the system is working, all that's missing is the GUI.

On reboot I get the xubuntu splash screen with the moving bar but
that's my lot, when it disappears I get no login screen or anything
more at all.

There don't seem to be any errors in /var/Xoef.0.log.

Does anyone have any idea what the problem might be?  How can I set
about diagnosing the problem?

If it's anything like my server updates this morning, my nvidia drivers for
my XFX were wiped.
I can't start x either, due to 'low graphics mode' and the most god-awful
mess on the screen (its unusable), so I'm relegated to terminal mode only at
the moment.
What is the graphics card you've got...
Check dmesg (there's probably a seg fault there related to X server).
I'm a bit puzzled as to how to fix mine as well, but I'm working on it (I
also have sent a message to the group this morning on these woes).
Even if I reboot into the last kernel I still have to manually tweak the
graphics settings to get a really low-res desktop, but my primary display
(Dell 1503FP digital) doesn't work at all.
Luckily my 42" plasma tv is plugged into the secondary dvi port and that's
what comes up... it's a challenge.

Regards,
Jack

There's no .xsession-errors, it hasn't got that far.  Also, as I
reported, there don't seem to be any problems in /var/Xorg.0.log.

It's an Intel chipset motherboard.

    Intel Corporation 4 Series chipset

The only odd thing I can see in /var/Xorg.0.log is:-

    (II) intel(0): Setting screen physical size to 304 x 228

I suspect that there's no way my monitor is going to manage that resolution!

"Physical size" is the size of your screen in milimeters. Your system uses 
that data, combined with the width and height in pixels, to calculate the 
PPI of your screen. That information, in turn, is used for things like 
setting the right font sizes.

Oh, OK, so that's not the issue then.

I just can't find any error messages or processes failing to start,
everything looks perfect but I don't have a login/GUI/X.

Both gdm and X are running, it's just (!) that they produce no display.

Did you check the time stamp of /var/log/Xorg.0.log? Maybe it is from 
the last successful start and now it doesn't even get far enough to 
write a log file.

Yes, it's definitely a new /var/Xorg.0.log file, time stamp just a few
minutes old (well, it was when I looked just after rebooting).  Both
gdm and X are running, just no display.

It appears to work perfectly!  E.g. after killing gdm:-

    root@chris:/var/log# gdm &
    [1] 5653
    root@chris:/var/log# jobs
    [1]+  Done                    gdm
    root@chris:/var/log# ps -ef | grep gdm
    root      5654     1  0 21:19 ?        00:00:00 gdm
    root      5655  5654  0 21:19 ?        00:00:00 gdm
    root      5659  5655  1 21:19 tty7     00:00:00 /usr/X11R6/bin/X :0 -br -audit 0 -auth /var/lib/gdm/:0.Xauth -nolisten tcp vt7
    gdm       5669  5655  1 21:19 ?        00:00:00 /usr/lib/gdm/gdmgreeter
    root      5671  5643  0 21:19 pts/0    00:00:00 grep gdm

That looks perfectly normal to me, no errors on terminal, and nothing
wrong in the (new) /var/log/Xorg.0.log either.

One thing I've noticed in Xorg.0.log:-

    (II) intel(0): Output VGA disconnected
    (II) intel(0): Output HDMI-1 disconnected
    (II) intel(0): Output HDMI-2 connected

My motherboard has a single DVI-D socket, is the output being sent to the
right place?

Sorry, yes, hopefully this message is just to xubuntu.

From the USN (Ubuntu Security Notice) for this security upgrade:

"ATTENTION: Due to an unavoidable ABI change for Ubuntu 8.04 and 8.10,
the kernel updates have been given a new version number, which requires
you to recompile and reinstall all third party kernel modules you
might have installed. If you use linux-restricted-modules, you have to
update that package as well to get modules which work with the new
kernel version. Unless you manually uninstalled the standard kernel
metapackages (e.g. linux-generic, linux-server, linux-powerpc), a
standard system upgrade will automatically perform this as well."

I would guess that you need to upgrade the module that runs your video
card, a 'sudo apt-get update && sudo apt-get dist-upgrade' should work,
if you've compiled the module by hand you will have to do that over
again with the new kernel packages.

.... some progress!

If I disconnect the DVI-D lead to my monitor and use an analogue VGA
connection instead I get a working system!  However the resolution
isn't as high as I would like and the display quality isn't as good as
with the DVI-D connection (when it worked).

So, it is *something* to do with the DVI-D recognition and configuration.

Any ideas anyone?
