I have several questions.
I've installed Red Hat 7.0 on a AMD Athlon 900 mhz. I installed both KDE, and Gnome, KDE as the default. I set it in the installation to not start in graphical mode. Now, it boots up in CLI mode (just as i wanted), and i can give it the command 'start x', that takes me into KDE, im wondering how i can change it from KDE to Gnome.

Second question,
I've replaced my Voodoo3 with a Nvidia TNT 2 because in order to get Red Hat to work with a 3dfx i had to get extra drivers and didnt wanna go through the trouble, anyway, while installing, i set a screen resolution (800x600), and now i wanna change it to 1024x768 and CTRL ALT +/- doesnt seem to work, how can I change the resolution? Would be all right just to edit Xf86 setup?

Thanks in advance for your help, its much appreciated.
-Regards

The first easy fix is just to run xf86config again to switch drivers for X as per the video card issue. I run the generic 'nv' drivers and they work great, not gonna fix what ain't broke by downloading a bunch of nvidia/riva specific drivers. If you want a full range of window managers to choose from and be able to pick your default, try running gdm. It's Gnomes Display Manager and you can configure a good number of things as well as default window manager etc...That's what I like to use anyhow.

Wonderful, Ill try those and get back to you. Thnx again, help much appreciated.

Sorry, forgot to mention the xwmconfig option. Type that at the command prompt and you can set default there too.

switchdesk gnome

that is the easiest way to switch your window mgrs, that i have found.

also in /etc/system/desktop you can change the default there as well..
