Screen resolution on Fluxbox

hi, i need help.

How can i change the screen resolution on fluxbox?

I wanna be in 800x600 (yes ugly, but i need it), now im in 1024x764, i just edit the
xorg.conf, but the virtual screen is bigger than the screen, i change the HoriSync and VertSync and nothing, in kde i do it well with the control panel but in fluxbox i dont know how to do it.

All you need to do is specify "800x600" as the first and default resolution in xorg.conf. Print out your xorg.conf.

yes, i did it, and i get 800x600 but the screen is bigger than the physical screen, i have to move the mouse to see the rest of the window. Now i use xrandr to set 800x600 and looks good, yes i can add "xranrd -s 3" in the fluxbox init, but is not a good practice i wanna know: why if i set "800x600" as first end default option in xorg.conf i dont get a 800x600 that can fit in my physical screen.



here goes my xorg.conf:

Everything looks good. You will need to setup the Horizontal and Vertial Sync.

Download and install the package hwinfo, then run:

hwinfo | less

In Debian you can run "apt-get install hwinfo". In Fedora I think you can run "yum install hwinfo".

It may take a while for the screen to show the results. Search for the section "Vert. Sync". It will be in vi mode so type /Vert. Sync

Look at the sections "Vert. Sync" and right below it "Hor. Sync" and notate them.

Edit /etc/X11/xorg.conf and make the changes in the corresponding settings.

Let me know if it worked.

it works fine, thanks

I'm glad. The only other thing I like to tweak after my fluxbox install is the TrueType fonts. You may want to google for instructions. But basically you can copy the TTF files to a directory and then specify them in /etc/sysconfig or something like that, then you have to edit the beginning of xorg.conf. You'll like the way the fonts come out much clearer and crisp.

That's basically the basics you need to setup X really nice: resolution, fonts, (maybe the touchpad mouse). Good luck.
