Hi all,

I have ibm T23 with supersavage and I have a LCD monitor support 1440x900.
Now I can set my video card up to 1400x1050. Is it possible to force my video to use 1440x900? Or is there a way to word around?

Thanks!

Hi,

and welcome to LQ!


And should be a way to do that - however, it can depend on a few
things as to whether and how that can be done.

a) What distro are you using?

b) Which window manager/desktop environment are you using?



Cheers,

Hi, thanks for your reply.

I'm using slackware and gnome as the desktop. I also installed fluxbox.

I also found the following messages in xorg.0.log

Does this mean my card support 1440x900? Thanks

Good choice of distro ;}
Sure does. To enforce it you should be able to add a
line with the explicit resolution to /etc/X11/xorg.conf


Find your screen section, and add Modes "1440x900" to the
resolutions you're wanting to use.

I only assume that your section says Savage for the device,
but you get the gist :}

Thanks Tink, I added those lines to xorg.conf. When I start fluxbox, the screen is cut from bottom. I checked xdpyinfo, the dimension is 1400x1050. I also tried gnome. The resolution is automatically changed to 1280x1024. It seems my video card does not support it? confused.

Here are more info. from xorg.0.log:
(--) SAVAGE(0): Found 13 modes at this depth:

[173] 720 x 480, 75Hz
[17e] 720 x 576, 75Hz

Does it mean my video card only support those modes?

Which colour depth is it pertaining to? And how much video RAM
does the box have?


Cheers,
Tink

I tried 16 and 24. None of them works.
I have 16m video memory on board. My LCD on laptop has a max resolution of 1024x768 and the external LCD is 1440x900.

Which video driver did X pick for the Savage chip? Not that I have
any experience with these ...


Cheers,
Tink

I think it uses "SuperSavage". See the log:

Try:
Option "UseBIOS" "False"
It works for my Acer 1440x900 monitor.
UPDATE:Turn of the built-in LCD by:
Option "CrtOnly" "True"

Now I wonder if xorg can do dual-head xinerama.
UPDATE: Under Windows XP it does.
