Screen resolution in Linux

Hi!

I just recently installed Red Hat 7.2 and I was wondering, how to you change the screen resolution when linux is already installed?

My other question is, I can't seem to get my soundcard working. It's a Soundblaster Live card. Linux seems to find it...but it says something about I/O port error... Everything works just fine in Windows.

Thanks!

For your screen:

if you use a frame buffer:
edit the file /etc/lilo.conf as root.
and set the vga=
I don`t know the codes by hard.
You should not have a hard time finding them.
Or set : vga=ask
Then runn /sbin/lilo

else:
edit you /etc/X11/XF86Config as root.

OK I'll try that.

What If I'm running KDE???

In a nutshell.
KDE is the desktop managar.
It hendels the event`s on your desktop.
Your screen is set bij the X server.
KDE is the program that controles your desktop.
KDE it self uses the X server.

If you use a framebuffer the Xserver uses the res of the framebuffer.
Else it uses the reselution you configured in the /etc/XF86Config
BTW there are programes that can help you configure your X settings.

good luck

For Redhat, you can use Xconfigurator to set up your resolutions. Also, see Aussie's post in this thread concerning checking/editing your resolutions manually in /etc/X11/XF86Config-4.

Once you set multiple resolutions in the config file, you can change your res on-the-fly in Gnome, KDE, etc. by simultaneously holding down CTRL+ALT+the numeric keypad's "+" or "-" key.
