Hi
I'm trying install 8.10 on an old sony PCG-FX 340 laptop. For the most
part the install went smoothly, and the machine is working okay.
There's a couple of things I'd like to get working, but I'll pick the
most annoying one first.
I'd like to change the screen resolution of from 800 x 600 to 1024x768.
(The screen resolution tool in the admin panel, doesn't give me the
option.)
The laptop comes with a Intel 82815 815 chipset hostbridge and memory
controller and a VGA 82815 graphics controller.
Digging around at the usual sources for help there seems to be a couple
of different isssues with Sony laptops and screen resolution, esp
revolving around the 915 chipset, which don't seem to apply here.
What looks the most promising is modifying the x configuration file
(/etc/X11/xorg.conf) as per
http://ubuntuforums.org/showthread.php?t=1062691&highlight=sony+screen
+resolution+sony+laptop
I tried this changing the model name, and had a couple of problems.
First, cntrl/alt/backspace didn't restart x. So I rebooted and came up
with a screen that went blank at log in. I was able to recover, but
thought I'd ask here for suggestions and help before fiddling with
xorg.conf more.
Actually you are using the 815 chipset & the driver should be
xserver-xorg-video-intel.
First try this:
$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get install --reinstall xserver-xorg-video-intel
$ sudo apt-get install grandr
Log out and log back in. From a terminal:
$ grandr
That will bring up a GUI for monitor modes w/frequency options.
If that doesn't work reboot into recovery mode and use the xfix utility,
then resume normal boot. That supposedly _should_ resolve the problem.
If not, then it may be related to this:
<https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/288807>
There is an xorg.conf file included in that bug report that may work for
you.
Other possible info/suggestions:
<https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/214168>
You can also file a bug:

I missed the original post and if this answer doesn't fit, kindly disregard.
I had the same problem with my old Dell laptop. Someone (sorry I can't
remember who now) suggested modifying my xorg.conf file with the following;
Section "Monitor"
Identifier "Configured Monitor"
Horizsync 31.5-48.0
Vertrefresh 56.0-65.0
EndSection
and;
Section "Screen"
.... blah blah
SubSection "Display"
Modes "1024x768"
EndSubSection
EndSection
This fixed my Dell, might be worth a try. Just save a copy of your old
xorg.conf so you can go back if it is worse :-).
