Problems with res 1280x800
 

Hi,

i'm having trouble with resolution on Debian Linux. I have the XFree86 server runing, and installed the nvidia drivers for my nVidia GeForceGo 6200. This part works fine, but i have trouble setting the resolution of the screen. It's an X-Black widescreen which supports 1280x800, but i can only display at 1024x768.

I've tried many configurations but nothing worked at all.

Another trouble with screen is that console mode is only 640x480. Anybody knows how to solve it?

I attach my XF86Config-4 here,

thanks a lot for any help.

Insert this line into your "Monitor" section (underneath VertRefresh 43.0 - 90.0):
Also, change this line:

Modes "1280x800" "1024x768"

to this:

Modes "1280x800"

It might help to add this for all bit depths rather than just 24 bit.

i've tried so but it stills display a 1024x768 resolution

Hi, I have exactly the same problem you do...
no solution for that either...

Are you using GNOME? If so, then you need to go into GNOME control center and tell it to use 1280x800. Otherwise, GNOME may thickheadedly use whatever resolution it thinks it wants.

If you're using KDE or some other Window Manager, then this should have been sufficient.

I just solved my problem on my Vaio VGN-FS115M.
I found the correct modeline after trying several ones:

Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Monitor Model"
# http://www.linuxforen.de/forums/arch.../t-175226.html
Modeline "1280x800" 80.58 1280 1344 1480 1680 800 801 804 827
...
hope that helps

Yes! It's great! i tried a lot of modelines but didn't work. With that above this lines it works fine at 58 Hz.

But now i realise another problem. When i'm in console mode, the resolution is only 640x480, and don't know how to change. This also happens at system startup.

Thanks a lot!

:-D

When you boot up, the x-windows system isn't running. You want to include a boot option to increase the resolution of the vt's. You might try 'vga=791'. You can add it manually as an option to try it out before editing your lilo or grub configuration file. This option uses the frame buffer, assuming the fbdev is installed.
This gives the same resolution as 1024x768. I tried a higher resolution on my LCD screen, but it didn't look right.

There is a program that is a part of x-windows called 'gtf' that can analyze your system and give you a modeline to use.

gtf 1280 800 60 -x

Please, where you can find the gtf program?
It is not included in my distribution.

/usr/X11R6/bin/gtf

on my system anyway. Maybe that is not in your path the the moment?

There is no gtf file in my /usr/X11R6/bin/ ... :(
