widescreen 1440x900 not filling monitor!

[masnevets]

I just got a Hanns-G HW191D today and I have been tweaking with xorg to get the 1440x900 resolution promised by the product. It works, but there is a slight problem in that the top inch or so of the monitor is a big black strip, so that the 1440x900 does not fill up the screen, but is compressed into the space below that black strip.

I used 915resolution to replace the 1280x1024 resolution on my VBIOS, and trying to replace the others gives a "no input signal" error. I'm using the i810 driver and I have an Intel 845G integrated chip. I have tried most things and it will not fill up that top part of the screen. Before using 915resolution and using 1280x1024 resolution, the screen was filled but stretched to fill the width, so I know that the top part is usable. And this happens in GDM, Gnome, and Fluxbox.

I have attached the output of 915resolution and my xorg.conf. Please help!

You did try using gtf to generate the proper Modeline, right?

[masnevets]

yes I used gtf

Interestingly enough, if I use 1280x800, the black strip is about 2 inches big, and if I use 1440x1000 (nonstandard), it's gone. Now, I suppose I could use 1440x1000, but this is bigger than I'm supposed to have, so I worry this may damage my monitor. Also, I think the pixels are slightly stretched, so it would look best if I could get 1440x900 filling up the screen.

[masnevets]

Okay, I fixed it and damn it looks sweet!

It turns out that editing /etc/default/915resolution was not enough because it does not offer some arguments that were necessary. What I did was deleted my /etc/init.d/915resolution and replaced it with the following:

#! /bin/sh

/usr/sbin/915resolution 58 1440 900 32 1904 934
/usr/sbin/915resolution 49 1440 900 16 1904 934
/usr/sbin/915resolution 38 1440 900 8 1904 934

exit 0

The 1904 and 934 are two of the values from gtf. If someone else has this problem, you can probably figure out from my modelines which numbers to use.

Thanks for trying to help, though.

You know that you should probably edit /etc/default/915resolution instead of /etc/init.d/915resolution, right?

[masnevets]

/etc/default/915resolution does not offer a place for HTOP and VTOP

If you can just add this, then I can go back and change it, but otherwise, just giving the X and Y resolutions is not enough, as I mentioned because it does not fill the whole screen.

Damn! it does look sweet. Thanks to masnevets for the xorg.conf.
Just updating this section worked fine for my HW191D.

Btw, I have XUbuntu 7.04, and they are updating (as late as 2/07) graphic drivers
for 3dfx voodoo3 which is truly defunct graphics card in the market!
The world is often very kind.
Thanks!

Hi,

you shouldn't need to use 915resolution (you'll have video playback troubles) or mess with xorg.

simply install xserver-xorg-video-intel (which replaces the i810 driver) and press ctrl+alt+backspace.

this should solve your problems. (if my experience is anything to go by)
