Re: [vox-tech] monitor troubles

I tried that driver and it doesn't work with the 2.6 kernel, so I am using the one that came with X.

I think part of the problem may be that it isn't seeing that it has enough memory. I edited the line in the XF86config file to say that it has 64MB of video RAM, but using kinfocenter it only thinks that I have 4MB of video RAM.

You can add all modes, in the order of your preference, like this:

Modes "1024x768" "800x600" "640x480"

so you don't have to try each one.

Anyway, that's the sidenote. Since you got the sync information, set the
hsync and vsync rates in XF86Config:

HorizSync 30-100
VertRefresh 50-160

Furthermore, your video card needs to be supported by X. It looks like
Intel has their own driver and a support page:

I found the /etc/X11/XF86Config file and edited a few times. Here is
the most recent one that I tried:

Section "Screen"

Identifier "Screen0"
Device "VideoCard0"
Monitor "Monitor0"
DefaultDepth 16
SubSection "Display"
Depth 16
Modes "1024x768"
SubSection "Display"
Depth 24
Modes "1024x768"

When I restart X, I don't get any errors but the screen is still the
same size.

Is there a tool I can use to figure out the amount of video RAM or do I
have to look for manuals that might list that?
Thanks for all the help,

Yes it is an LCD monitor. I tried running xvidtune and got the message
"Video are not settable on this chip". If I check the control center,
it says that the screen size is 640x480 and has no other options for
it. How else can I up the resolution?

The first thing I would try is to follow the other poster's suggestion
and manually edit the configuration file.

However, if that doesn't work, you may be running into the same problem I
have had with my LCD monitor: XFree believes that you can't support a
higher resolution because it doesn't have the right specs on your monitor
and video card.

You need to tell xfree that your monitor has a very high range of
horizontal and vertical synch frequencies, and that your video card has
at least as much video RAM as it actually does. XFree will not allow you
to change to a resolution that it (a) doesn't think your monitor can
handle or (b) doesn't think you have the video memory to maintain.

You can do this in the configuration file mentioned by the other
poster--the places on the file that you need to make the changes
should be obvious.
