about display and gnome


I have install rhel 5 on my amd64 sempron and worked fine
The display was fine with 1024 X 768

One day I tried to install xine ( downloaded and installed via source)

But the next day, when I turned on the system, the display changed to
600 X 700

the option 1025X768 is not available on the system-config-display

How can I restore my resolution?

Suppose I want to remove all gnome desktop and then install it
how can i do it?

currently the system is using vesa driver

how can I use the appropriate driver for HCM780M monitor

No, it can be the configuration files, not the desktop itself. If the menu item "system->settings->screen resolution" (translated from German to English) fails (I guess you ment this), the problem is most likely with Xorg and the drivers you are using. What graphics card do you use? If it's an NVidia card, you should use "nv" drivers for 2D acceleration or the closed-source "nvidia" drivers from NVidia. The graphics driver is btw independent from the monitor.
If you are having trouble installing your drivers but you know which card you have, here's a list with how-to's on graphics drivers under Linux from this community (ATI looks troublesome, though): http://wiki.linuxquestions.org/wiki/...Graphics_cards

Thank U TITiAN

Now the display is OK. But i don't know what happened.

May be the result of reinistalling xorg. But now it is ok.

One more

I wish to study the window managers from the ground up.
So I think to remove all X components (I want terminal only) then install various
components, window managers etc

could u tell me the procedure to do

I am not familer with display managers

I don't know if you still want to know it, but for anyone's interest:
As far as I can tell, that there are mainly three popular (and easy to use) desktop environments out there:
  • Gnome - The GNU desktop, an environment with a good respect to standards (like file addresses and GnomeVFS capabilities); builds on the GTK+-library
  • KDE - A feature rich desktop, includes many useful tools. The Qt library on which KDE is built used to be closed-source, but has long been GPL'd.
  • XFCE - A minimalist desktop, starts quickly and saves resources (still has a good look and many features); builds on the GTK+-library
You can run all applications on all desktops, though GTK+-applications have a dump look on non-GTK+-desktops (e.g. KDE). (not sure if you can't change that)

All desktop environments need one X-server, i.e. Xorg (I don't think there are others that have comparable features like Xorg because Xorg adopts things like AIGLX).

So if you really want to start from terminal, it shouldn't be much of a pain to install you favorite desktop since Xorg should be a dependency. It'll something like yum install kde/gnome/xfce4 once you are logged in as root; maybe yum install xorg if it's not done automatically.

If you want to read a lot of information, Wikipedia is your friend: http://en.wikipedia.org/wiki/Desktop..._Window_System

Is that what you wanted to know?
