Xorg.o.log

I use HP COMPAQ Presario 2500 series Laptop whose LCD screen is damaged (I can
see colors on small patches and recognize the GDM login screen, Ubuntu Desktop,
Kubuntu Desktop etc.). It is hooked up to COMPAQ V45 external monitor and being
used as a Desktop.

I am presently using Ubuntu Gutsy Gibbon and the display works even after
deleting xorg.conf file. This means auto detection by X window system is
working. Gutsy also has xrandr 1.2 and xrandr -q tells me that both VGA-0 and
LVDS configurations are correct.

I downloaded Ubuntu 8.04 alternate iso, and used it to install Hardy Heron on
another partition on the Laptop. It is a perfect installation but I am unable
to use. Everything is ok till GDM starts, the VGA monitor comes to standby mode
on login screen. I can see through the patches on Laptop the GDM login screen,
enter userid and password, hear the welcome music of Ubuntu desktop and confirm
its loading (through the patches) but alas! the monitor remains on standby
mode.

On pressing Ctrl alt F1, I can get the console on the monitor, login and verify
that the monitor is configured correctly through the command:
xrandr -display :0.0 -q

The settings I get for VGA-0 and LVDS are same which I get in Gutsy.

Assuming that VGA-0 which is shown connected is disabled by GDM (or X), I try
to enable it (through --auto):
xrandr -display :0.0 --output VGA-0 --auto --mode 1024x768

But when I go back to X through Ctrl Alt F7 the monitor returns to standby.

I know about the new GUI utility displayconfig-gtk to set up the second monitor
but can't use it since the Laptop screen does not work.

My video card is:
01:05.0 VGA compatible controller: ATI Technologies Inc Radeon IGP
330M/340M/350M

I have seen similar bug report for this card but it is for xserver 1.3. Ubuntu
Gutsy has this xserver and VGA-0 is working in my case.

Since in my case it is xserver 1.4 I am reporting it.
