X server - special configuration

[amitye]

Hi all,

I am running Fedor13 on an ATOM D510. everything is running fine but now I need to do special configuration.

I need to use my machine as the server ((connected to the display) while the client is another computer in my network.
In addition I need to set the color depth to 8 bit. and running the MOTIF window manager.
I got the following problems:

1, I cant find Xorg.conf in my system.
2. I kill the x-server (init 3) and start "Xorg -depth 8" , but the I get a blank screen.
3. how can I switch to MOTIF window manager?

Thanks.
Amit

Perhaps you can start by explaining why you need to reduce your display to an 8-bit color depth (only 256 colors). Typically this is because some X-windows applications are pseudo-color applications, limited to 256 colors and need to switch pallets to get other colors. I've had to modify some old Solaris 8-bit applications to work in a 24-bit truecolor display (modern X-servers) and it is a pain in the you-know-where!

Also, in X-terminology, the server is the display machine, whereas the client is the machine where the code is executed (not displayed). Is that what you mean?

The MWM (Motif Window Manager) is a REALLY outdated piece of stuff. FWIW, you can use KDE or GNOME window managers (or any current Linux window manager) to run Motif applications. You do need the appropriate libraries installed, but I do run them frequently on my KDE 3.5.4 CentOS/RHEL workstation.

Hi Rubberman

1. You are correct. The 8bit issue is needed by the application.
2. I am talking about the x-server.(where the display is connected)

and my questions remains:
1, I cant find Xorg.conf in my system.
2. I kill the x-server (init 3) and start "Xorg -depth 8" , but then I get a blank screen.
3. how can I disable the desktop from getting-up. I want only the X.

I assume you are running Linux for the X server? If so, then you will find the X11 configuration files in /etc/X11. You may, or may not, be able to set it it an 8-bit color depth. To some extent, it depends upon the hardware. I had trouble getting my nVidia board to work with 8-bit color also. A bit of a PITA, but then I think any such "antique" applications should probably be re-written using more modern toolkits such as GTK+, Qt, Wx, etc. As I mentioned, I had to port some old Unix X11 applications written with Xlib and Motif to 24-bit trucolor displays. It was definitely a pain, but it only took me a couple of weeks to do it. Fortunately, most of the X11 code for all of the applications was concentrated in a few common libraries.
