Question xorg.conf: default screen resolution smaller than max. resolution ??

Hi all!

I have a 19" monitor that can do 1600x1200, but that is too small pixels for my eyes - I prefer 1400x1050. But I'd like to be able to use 1600x1200 e.g. for gameplay (quake4 does not start in 1600x1200 when this mode is not defined in xorg.conf! )!

When the Modes entry in my xorg.conf contains
"1400x1050" "1280x960" "1024x768" ...
No problem: 1400x1050 is used. And when I add the 1600x1200 in front:
"1600x1200" "1400x1050" ...
...1600x1200 is used.

I figured the first entry is the default entry, so I tried
"1400x1050" "1600x1200" "1280x960" ...
...and still 1600x1200 is used for default?!?

Is there a possibility to have 1600x1200 in xorg.conf, but to have 1400x1050 as default screen resolution?

Any help appreciated!

gtf 1600 1200 85
you'll get somthing like this
$ gtf 1600 1200 85

# 1600x1200 @ 85 Hz (GTF) hsync: 91.50 kHz; pclk: 143.47 MHz
Modeline "1152x864_100.00" 143.47 1152 1232 1360 1568 864 865 868 915 -HSync +Vsync(DU NOT USE THIS LINE - IT DOES NOT match YOUR MONITOR)
you need the line with Modeline in your xorg.conf
Section "Monitor"
Identifier "iiyama"
VendorName "1152x864_100.00"
ModelName "1152x864@100.00 Hz"
# 1152x864 @ 100.00 Hz (GTF) hsync: 91.50 kHz; pclk: 143.47 MHz
Modeline "1152x864_100.00" 143.47 1152 1232 1360 1568 864 865 868 915 -HSync +Vsync
Option "DPMS"

then your
Section "Screen"
Identifier "Screen0"
Device "Card0"
Monitor "iiyama" #
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1152x864_100.00" # edit this line the way you want it

Thoddy, let us know if you understood andygo's reply

Normally there is a script which sets the resolution at boottime. This default resolution can be changed in a gui.

There are various ways of getting different resolutions for different apps. Mostly, you just write a script to load the app, but setting resolution first.

If the maximum resolution is too fine for you with the default configuration, try customising your theme/desktop/panel settings to use larger point sizes. Then you'll still be able to see everything and the pixel size won't matter.
