I upgraded tonight and everything seemedto being going well until the reboot at the end when my machine froze at the login screen.

I've rebooted again and again and again......with the same thing happening. Has anyone got any suggestions what to do from a command prompt (which I can access through GRUB !!!)

Many thanks

Might be the same black screen problem I've been getting with Intel graphics since Aug 13. Excerpting Developers comments from my Launchpad Bug #259385:

"== Desktop effects and Intel 830MG and 845G video cards ==

There is a bug in the intel video driver for the older intel 830 and 845 integrated video cards that are used on laptops like the IBM R30. Desktop effects with compiz will not work on those chips and freeze the system."

From what I've seen on the posts there are a LOT More chips that have symptoms like this.

My workaround is:
Boot in rescue mode
select root shell prompt
sudo apt-get remove compiz
sudo apt-get remove compiz-core
exit
resume

If that works you're O.K. except no special visual effects. If you want to try compiz again, install with Synaptic.

Thanks, Jerry.

Unfortunately, it didn't sort the problem - but I'll not reinstall compiz just in case it makes things worse.

You could try installing kde, or even xfe. I have heard just a few people who can install these two but not gnome.


sudo apt-get install kdm
sudo apt-get install kubuntu-desktop

sudo apt-get install xfe

If you need to undo :-


sudo apt-get remove --purge kdm
sudo apt-get remove --purge kubuntu-desktop
sudo apt-get remove --purge xfe


If you can boot x via a log in prompt, I don't understand if you login prompt was graphical or text, you could try reconfiguring X11.


sudo dpkg-reconfigure xserver-xorg

Or else you could try changing your kernel
Visit http://packages.ubuntu.com/intrepid/base/ and :


sudo apt-get install linux-image-2.6.27-7-generic

or install a diffrent kernel image from the one you are using.

Well, I seem to be getting somewhere as the cursor is now the arrow but it's still frozen.....

Any more ideas ?

Have you tried using kdm instead of gdm? At a terminal run sudo dpkg-reconfigure kdm and select kdm instead and see if that works.

No progress, I'm afraid.

(I've lost the arrow again, BTW, but that was before I tried your suggest from the root command prompt.

Look at your log files that should be available from
/var/log/kdm.log or
/var/log/gdm.log

depending on which desktop manager you are using.

It should give you a clue (and just a clue) as to what is happening.

try :

sudo nano /var/log/kdm.log // -or-
sudo nano /var/log/gdm.log

for clues.

Under kdm, I get two messages

mieqEnequeue: out of order valuator event; dropping

and

EQ overflowing. The server is probably stuck in an infinite loop.


There's no entry in a gdm log as far as I can see. I do get further - I can log in and it starts loading up the desktop but then cycles back to the login screen. Compiz has been uninstalled so that potential solution described elsewhere is ruled out.

Am I right in thinking that there's not a workaround for this yet ? Is there anything I can do to get my desktop machine working again ? (Thank goodness for my Linpus-driven Aspire One !)
