Hi Everyone,
This seems to be the place to ask this.
I have a few IBM 8514 XGA monitors that I would like to use if possible. I have nvidia GF2 dual head cards and have very modern 1600X1280 64k colors NOKIA monitors on the primary side of these cards. Is there a rule that the monitors on the 2 heads be similar, or can they be this different? While the newer monitors have nice fast refresh rates the 8514's have 31Hz rates but very long persistance gourgious color phosphors.
I do NOT want the 2 monitors to be one 'stretched' desktop, I prefer that they have seperate material. This setup could be ideal for the display of photos and such on the 8514.
Can anyone offer assistance?

(app-r) APPENDIX R: CONFIGURING MULTIPLE X SCREENS ON ONE CARD __________________________________________________________________________ Graphics chips that support TwinView (see (app-i) APPENDIX I: CONFIGURING TWINVIEW) can also be configured to treat each connected display device as a separate X screen. While there are several disadvantages to this approach as compared to TwinView (eg: windows cannot be dragged between X screens, hardware accelerated OpenGL cannot span the two X screens), it does offer several advantages over TwinView: o If each display device is a separate X screen, then properties that may vary between X screens may vary between displays (eg: depth, root window size, etc). o Hardware that can only be used on one display at a time (eg: video overlays, hardware accelerated RGB overlays), and which consequently cannot be used at all when in TwinView, can be exposed on the first X screen when each display is a separate X screen. o The 1-to-1 association of display devices to X screens is more historically in line with X. To configure two separate X screens to share one graphics chip, here is what you will need to do: First, create two separate Device sections, each listing the BusID of the graphics card to be shared, each listing the driver as "nvidia", and assign each a separate screen: Section "Device" Identifier "nvidia0" Driver "nvidia" # Edit the BusID with the location of your graphics card BusID "PCI:2:0:0" Screen 0 EndSection Section "Device" Identifier "nvidia1" Driver "nvidia" # Edit the BusID with the location of your graphics card BusId "PCI:2:0:0" Screen 1 EndSection Then, create two Screen sections, each using one of the Device sections: Section "Screen" Identifier "Screen0" Device "nvidia0" Monitor "Monitor0" DefaultDepth 24 Subsection "Display" Depth 24 Modes "1600x1200" "1024x768" "800x600" "640x480" EndSubsection EndSection Section "Screen" Identifier "Screen1" Device "nvidia1" Monitor "Monitor1" DefaultDepth 24 Subsection "Display" Depth 24 Modes "1600x1200" "1024x768" "800x600" "640x480" EndSubsection EndSection (note: you'll also need to create a second Monitor section) Finally, update the ServerLayout section to use and position both Screen sections: Section "ServerLayout" ... Screen 0 "Screen0" Screen 1 "Screen1" leftOf "Screen0" ... EndSection For further details, please refer to the XF86Config manpage. I guess the trick would be to use the same card but have it assign disretely rather than generally, if I understand what your trying to accomplish. They would both be device 0 but monitor 0/1 and screen 0/1. The big question is can you port two sessions/screens ate the same device. whether or not this kludges the driver is another question. Good luck, Curtis. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.2-rc1-SuSE (GNU/Linux) iD8DBQE+/mXViqnGhdjCOJsRArrGAJ9xW6If9tstBe3oqNSNC8Oq+W8UaACfW5fI gPU1IgoPTcVGErzE9zzgeiE= =sxY+ -----END PGP SIGNATURE-----
