Hye to all i required these two drivers which have been listed below
plz if anyone have those drivers plz let me know or u could mail those drivers utkarsh_rawat@rediffmail.com.

VGA compatible controller: Intel Corporation 82946GZ/GL Integrated Graphics Controller (rev 02)

Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01)

You already have those drivers.
The i946GZ chipset uses the i810 driver in your kernel.
The audio drivers would be AC97 and intel-hda, also in your kernel.

I take it you have trouble with video and sound?
Show us the output of:

lspci (for audio and video controllers - copy and paste)

cat /etc/X11/xorg.conf (the device section about video)

lsmod | grep snd

lsmod | grep intel

.... and tell us about the problem.

Hye Simon
I 'll be really greatful if u could see all this & rectify my problem

As u have said i gave the command lspci it showed:

So far so good...

try lsmod | grep i915 or lsmod | grep i810

But, what is the problem?

Hi
The problem what iam facing is regarding graphic is resolution which is set to only 640X480.
& regarding sound iam not able to hear anything.I believe we require drivers to install which i have mentioned above

The command which u have said to execute .It says :
lsmod | grep i915 or lsmod | grep i810
grep: or: No such file or directory
grep: lsmod: No such file or directory

Let me be clear: the command is lsmod | grep i915, if this gives nothing then try lsmod | grep i810 ... claro?

Which distro do you have?

... this is not uncommon. Need to see cat /etc/X11/xorg.conf. Put it in "code" tags. Likely cause: you need to change something in that file - either the mode or the refresh.

... also not uncommon. Enter alsamixer in a terminal and make sure sound is not muted.

... as mentioned above: you already have the correct drivers.

If this were Windows, you would have a point. It is tricky, when everything is closed source, to tell when you have the exact drivers for your HW+installation. Odd or erratic behavior is often a symptom of not having quite the correct binaries.

Not so with open source - the drivers are too well documented.

dear simon
I gave this command
lsmod|grep i915
i915 21697 2
drm 67029 3 i915

--------------------------------------------------------------------------
When i gave this command
lsmod|grep i810
it did nothing

As iam using redhat 5 In screen resolution the mode is showing only 640X480 .I am totally confused
--------------------------------------------------------------------------------
As in sound i gave command alsamixer
Card: HDA Intel │
│ Chip: Analog Devices AD1986A │
│ View: [Playback] Capture All │
│ Item: Headphone
But now iam facing new problem sound is coming but whenever iam increasing or decreasing the volume ,sound sudennly stops
I am totally confused

... presumably "Red Hat Enterprise Linux 5"? Server version with a GUI added after perhaps?

You got it right - you need to edit that modeline:

su -c gedit /etc/X11/xorg.conf and add "1024x768" (or what resolution you want) to that mode line like this:
Restart X.

... sorry for making you print out xorg.conf twice, I got mixed up.

Hmmm... There doesn't seem to be a monitor entry, but you seem to get a screen OK.
We'll worry about that and your sound after.

Hye again
I gave this command in terminal
su -c gedit /etc/X11/xorg.conf it says
su: user /etc/X11/xorg.conf does not exist

Well ... become root then:

$ su -
[password]

# gedit /etc/X11/xorg.conf

(I think the entire command after the -c needed to be in quotes.)

Or use sudo:

$ sudo gedit /etc/X11/xorg.conf

... whatever it takes, but get that file edited.

Great stuff Simon u r great
It worked thanks alot . Now tell me what to do next
