Default PseudoColor, 8 bits, CIOverlay and all those things..

Hi,

I have a legacy app that runs on an IBM PowerPC workstation (AIX 4.2.0). I run this app remotely on windows boxes using Xming and/or XManager sucessfully. This app needs 8 bit mode (pseudocolor). Now, I need to run this app from a Sun Ultra 24 (core2 quad) with a Nvidia Quadro FX 1700 graphics card and RedHat EL 4.7 x86-64.

As I saw in this forum, I have to disable composite and xinerama extensions, enable CIOverlay and Overlay options. I did that. Now xdpyinfo | grep PseudoColor shows 5 entries.

When I run the app on a telnet session, the first screen appears sucessfully (even without CIOverlay on xorg.conf), but when I click a button to open an option window, I get the following error:

Warning: Cannot find Visual of class PseudoColor for display 10.36.9.131:0.0
X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 78 (X_CreateColormap)
Serial number of failed request: 4
Current serial number in output stream: 6

Anybody knows what I missed?

I forgot! I'm using drivers from nvidia, version 180.22 for x86-64. I think is the latest...

The same happens when I call:

Xnest -depth 8 :1

or

Xnest -class PseudoColor -depth 8 :1
