[SOLVED] boot hang on upgrade to 10.04

[HardwareMike]

Upgraded dual boot XP / Ubuntu 2.6.31-22 (still works) to 2.6.32-22, which hangs on boot.
"2.6.32-22 recovery mode"(and "continue" dies at "Checking battery state".
Ctrl Alt F3 gets a prompt and the login works.

The machine is a Thinkpad g40, which has worked on 9.10, except for
wireless distance issues (the G40 has the Atheros AR5211, which seems
to be a problem, at least per the forums, and my distance limits experience)

I get the same mount and chroot messages, followed by scrolling msgs,
and then a blank screen on attempting to boot 2.6.32-22. And, as indicated,
2.6.31-22 boots and the apps I checked work fine. On the upgrade, there
were several msgs about non supported apps and a grub question,
which I (naively) answered as use the package version (and was
somewhat surprised when dual boot still worked - but impressed and
happy

I cloned my hard drive prior to the upgrade, so can revert to 9.10, but would
like to run 10.04 LTS. Any suggestions. or should I wait for a while to
upgrade?

ps: As I am a hardware guy, I wouldn't ordinarily post to this forum, but since
I'm having the same problem, I thought you software guru's wouldn't mind

Hi and Welcome !

Which Graphics Card do you have?

[HardwareMike]

My laptop has the "Intel 82852/82855 GM/GME" graphics contoller.

Hmm ..... I see some posts referring to this graphics chip set ....

X/Bugs Lucidi8xxFreezes (can't post url)

Is this the problem? Should I run the two commands in grey background?

[devils casper]

Check the contents of /etc/X11/xorg.conf file, if any.
What is the output of this command :

grep -i driver /etc/X11/xorg.conf

[HardwareMike]

Second answer:
I'm using what came with 2.6.32-22, which apparently is xf86-video-intel 2.9


First answer:
Hmm.. didn't see that file at /etc/X11

but did run lshw -C video and got the output below; is the i915 driver info
sufficient?

(This is from the working 2.6.31-22 boot -- did you mean for me to get the info from a
terminal via the 2.6.32-22 recovery boot ??)

Thanks.

Try using "vesa" driver. It works fine with mose of Graphics Cards.
Press Alt+F2 and type this

gksu gedit /etc/X11/xorg.conf

It will open an empty xorg.conf file in Gedit with root privileges.
Copy contents give below and paste in xorg.conf file. Save file and reboot machine.

Section "Device"
       Identifier "Configured Video Device"
       Driver    "vesa"  
EndSection

Section "Monitor"
         Identifier "Configured Monitor"

Well ... the vesa driver would surely work. It looked to me like that was the driver used
in failsafe graphics mode. In the meantime though, I'd been looking around at the
posts about i8xx boot issues (the large number of posts), and noted that several
folks had success following the Lucidi8xxFreezes workaround(s) suggested.

So, thinking that I was about to reclone my drive back to 9.10 anyway, I tried
workaround A, as that seemed simple and most likely to fix my problem.

And

Success -

My G40 is now working on 10.04 LTS

The Lucidi8xxFreezes -- Workaround A did the trick, after getting a login screen
from recovery mode.

Thanks to all.
