Screen resolution on a sony laptop.

[Al Black]

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

+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.

Thanks
