How do i change the brightness.contrast and gamma in linux like you do in windows?
Also how do I get rpm files to work. I use the gnome RPM file expander and even when I do it pops up a window thats hows is inflating but thne after that nothing else happens and i never hear of the program again.

Welcome to LQ.

With respect to your RPM problem... has the file been installed? Once you've run GnoRPM (or whatever it's called), and you think that it's installed, open up a terminal (the thing that looks like an ol' DOS box in Windos) and see what happens when you type in the first few letters of the name of the program that you just installed, then press <TAB> and see if it autocompletes the name of the program. If it does, then it's installed, it's just not putting it on the foot-menu (the gnome menu thingy).

Hope this helps (a little).

ok I'll try that
BTW I'am a real real real newb to this stuff :P
I just installed linux on my new 40gig Hard drive I got I couldn't install it before cuz i neverh ad enoguh space on my 10gig one.
The very dark screen in linux is kidna getting annoying :\
How do I add it to my foot menu or whatever?

It should do it by default, but some programs don't. You could run the menu-manager... or something. Sorry I can't really be of much help on the Gnome specific front... I didn't like it when I first used it, so I don't now (I'm a plain Sawfish person... but that's another thread).

What distro have you installed, BTW? You haven't filled in your details yet (I know you've only just joined, but there's no time like the present).

I'am using Red Hat 7.3
I've installed all the packages except for the enterteinment and games package.

How do I open tar and tar.gz files btw?

bump

bump, I know how to use tar and .gz files now but I still need to know how to adjust the brightness,contrast and gamma like you do in windows.

umm anyone????

Hey! Calm down! I just had a peek, and you should find something called xgamma on your system. From a text console, type man xgamma to see the manual on how to use it. From the description line:
xgamma allows X users to query and alter the gamma correction of a monitor via the XFree86 X server video mode extension

1 problem every time I reboot linux it reverts back to the normal 1.0 gamma. how do I make it so it remembers the gamma I set it to?
