As I say the workaround does work but, depending on the monitor, can
result in an unsuitable screen resolution. So you'll have to brush up
on your xorg.conf or RandR settings :/

I've tried an i865 and the results have been rather erratic. I'm not
convinced about the PSU in that machine though, so I'm reluctant to say
what the results are. I've only seen the problem on i810 and not seen
any reports for other chip sets so I don't know. It may work on some
i810 based boards as this chip set was always a bit problematic with
different manufactures wiring it up in
different ways.

All my tests have shown the problem is reproducible with the live-CD and
that the alternate ISO will install but on reboot will fail with the
segfault problem. So you'll have to reboot to recovery mode. See my
post 'Recovery Mode Failure' to see the workaround for that problem.
Looks like anybody with video problems is going to have fun with this
upgrade and is going to have to put in a bit of work to get things working.

Yorvyk:<br>
<br>
Thank you very much for the additional information. <br>
<br>
Your initial e-mail on this problem had me worried, but it spurred me to action (to do some testing of 12.10). <br>
<br>
I downloaded the current Lubuntu 12.10 build, and tried it in all 7 machines in my test-bed. My test-bed includes a 450-megahertz HP-Vectra, and a Compac P933 (933 megahertz). <br>
<br>
It worked on all of them - including my primary machine (which depends on the Intel graphics) that I was worried about. <br>
<br>
Two of the machines depend on the xserver-xorg-video-intel package, and both of them worked with no problems. These two machines use the following chipsets: <br>
<br>
Dell™ Dimension™ 1100, chipset= Intel 865 GV<br>
<br>
Dell™ Dimension™ 8200, chipset= Intel 850 or 850E<br>
<br>
The two other Dell machines use a Nvidia card for graphics, so I don't know if their internal Intel graphics would have had a problem. <br>
<br>
Anyway, I <i>do</i> appreciate that you alerted me to a big potential problem, and relieved that it turned out not to be a problem. <br>
<br>
The other machines tried were an Acer Aspire laptop, a Dell Optiplex 260, a Dell Optiplex 240, an HP Vectra 450 mHz, a Compaq P933. <br>
<br>
The live CD worked on all of them. I am very much relieved! <br>
<br>
The only problem I encountered was that when I tried to run the system profiler/benchmark tool, it presented 3 successive empty dialog boxes, which I had to dismiss, not knowing what they were attempting to alert me about. This happened on all of the machines. <br>
