1280 x 1024 resolution on Mandriva 2006 [solved]

ilia_kr · February 15, 2006

I've installed the MandrivaLinux Free 2006 on my old box.

At first, i decided to upgrade previous installation (MDK 10.1), and so i did. The screen was allright (1280 x 1024 res).

The upgrade wasn't so good, it missed some packages and coused me a lot of problems, so i formatted the partition and installed from scratch. The new installation solved all problems but now i can't setup the screen res'. The OS recognizes my video card (see spec) but the monitor gives an error message : "out of range 51.1 / 47 hz".

My monitor's refresh rate (from manufacturer):

horizontal: 30 - 83 kHz

vertical: 56 - 75 hz

How can i fix this? 10x.

I'm using xorg, not xfree86, is there any difference?

daniewicz · February 15, 2006

Doesn't matter. You need to make the appropriate changes to /etc/X11/xorg.conf

If you need help putting together modelines for xorg.conf check here:

Is there some program that automaticly configures the display? How does Linux configure the display after the installation?

No, it's not- Linux does absolutely nothing by itself, but some distros have installation scripts which take care of setting the display at the end of the installation.

But there are several tools which do that: xorg's "xorgconfig" for setting without X running, "xorgcfg" (same thing, but with graphical environment), and in mandriva mcc (can be run with or without X running).

Can you copypaste the useful lines from your /etc/X11/xorg.conf here?

Check whether the package......monitor-edid...... has been installed. If not then install it.

Best to reboot and then when completed you open MCC----------->Hardware-------------->Configure your monitor and double click on the highlighted line titled Plug'n Play.

Close out then log out and back in again.

This time open KDE Control Centre ---------------------Peripherals ----------> Display and select your screen size etc there. Click apply.

You might need to log out and in again but by now you should be OK. There are not too many Monitor types that monitor-edid can't handle.

Cheers. John.

I have that package installed and KDE Control Center does the same, i mean it shows the options that i've seen in the xorg.conf.

I've installed the MandrivaLinux Free 2006 on my old box.
At first, i decided to upgrade previous installation (MDK 10.1), and so i did. The screen was allright (1280 x 1024 res).

I remember that with 2005LE i had the same problem. I think there are 2 possibilities:

1) MDK 10.1 has better tdfx video driver

2) MDK 10.1 uses older version of xorg that still can handle my card

Can i install some 10.1 RPM on 2006 that is somehow connected to the issue?

ilia_kr · February 18, 2006

Finally i solved the problem, it was the wrong dotclock value.

Thank you daniewicz very much, althoug the second link you provided wasn't useful.

Thank you all for the attention!

You could simply change by hand

Virtual 1152 864

to

Virtual 1280 960

(which is real 4:3)

or

Virtual 1280 1024

...which is the more common choice in your "display" subsections and get what you want, but since you solved it another way I guess it could be considered odd...

I don't quiet get what you said :mellow:

Explain please...

I changed the mode line from:

'ModeLine "1280x1024" 108 1280 1328 1440 1688 1024 1025 1028 1066 +hsync +vsync'

to:

'ModeLine "1280x1024" 135.60 1280 1328 1440 1688 1024 1025 1028 1066 +hsync +vsync'

No, not there... I mean in the "display" section, not the monitor one.

Factly, since you have a TFT screen, you could wipe the whole monitor autogenerated settings, run MCC and define your screen as "flat panel 1280*1024 @ 60Hz".

I've done that before editing xorg.conf, didn't work. Tried several 1280x1024@60/75/74 options - same result.
