[SOLVED] xorg.conf for 1024x600 ?

[Trio3b]

pclos 2011.6 KDE on Toshiba NB305-N440BL (Intel Corporation N10 Family Integrated Graphics Controller) w/ native screen res of 1024x600. After install, noticed screen res in PCC was 1024x768. changed it to 1024x600, rebooted and checked xorg.conf which shows:

Everything looks ok to me but shouldn't that 1024x600 modeline be in xorg? Have also tried the xorg driver with same results (above is using the xorg driver). Is xorg just presenting the "nearest" resolution it can find even though PCC shows 1024x600?

Before I go mucking around with Texstar's XfDrake tip, should I just leave well enough alone. I have tinkered with xorg.conf before but would rather not if i don't have to. I do have a backup.

any help appreciated
Thanks

As far as I know you can have a modeline for every resolution and refresh rate your monitor can handle. But you don't always need them. If everything looks all right I wouldn't worry.

Fifteen years ago you sometimes had to compute all the modelines yourself -- with the knowledge that if you got something wrong your monitor would go up in smoke. Today you may not need them at all. (Your modelines for "TV fullscreen mode or DVD fullscreen output" are probably adjusted according to some of the PAL standards with 576 active lines and not to your monitor's normal resolution.)

Thank you. Am going to leave well enough alone for now as this is just a travel netbook mostly used for online stuff, and seems OK. The one I'm really having fits with is the Toshiba Satellite A305 over in laptop forums.

Thanks again.

"As far as I know you can have a modeline for every resolution and refresh rate your monitor can handle. But you don't always need them"

i understand the same

you can add the line if you like

be sure to set that resolution in pcc and in kde control center(configure your desktop button)
