Hello Xperts,
I have an unique configuration that I need your help and suggestions on.
Currently I have the following configuration requirements:
1) Supermicro Motherboard w/ Dual 2.4 GHz Xeon CPU running Mandrake
8.2 SMP
2) Main graphics card
AGP
NVidia Gloria 4 (Dual DVI Head - only plan to use one)
Viewsonic ViewPanel VP201m Flat Panel Display
Standard PS/2 Keyboard and Wheel Mouse
Running KDE or Gnome or similiar
Login Screen required
3) Secondary graphics card
PCI
Dual flat panel displays (Touch Monitors)
Matrox G450 (Dual Head - one to each Touch Monitor)
2 Touch LCD Monitor (Serial EloTouch X-Input)
No Mouse or Keyboard
Running a simple window manager (ie twm)
No Login Screen (initialize window managers on main screen
login)
The main display will show a tactical situation display. The secondary touch
monitor displays are used to present the operator with button panels and
interactive graphics. I want to run two X-servers, one for each graphics
cards. The keyboard and mouse need to be used by the main display. The
secondary displays do not need a keyboard or mouse, but we would like to
integrate the touch stream (serial, or USB) into the X-Server as left-button
press and unpress events.
Initially I have tried using an additional mouse and an CRT until the above
Touch LCD Monitors are delivered. I have been trying Miguel Freitas's
solutions decribed at (http://cambuca.ldhs.cetuc.puc-rio.br/multiuser/) and
(http://cambuca.ldhs.cetuc.puc-rio.br/multiuser/g450.html) but without
success. Using the same VT locks up the system. Instead of reconfiguring
the Kernel to disable USB_KEYBOARDS, I have been using a Dummy (Void)
Keyboard. These configuration work separately using two different VT (vt07
& vt08).
Using Ximerama, the graphics cards seemed to have worked when I made the
G450 the primary card in the BIOS. But this doesn't meet the above
requirements since the mouse is used across all displays.
I am looking for any suggestions on how to do this. I may try the "Linux
Console" project (http://linuxconsole.sourceforge.net/).
Thanks for your help,
