Re: TwinView not working: FX 5200 on Ubuntu 6.06 LTS
I see a few potential problems in your X log:
(EE) NVIDIA(0): Failed to initialize the GLX module; please check in your X
(EE) NVIDIA(0): log file that the GLX module has been loaded in your X
(EE) NVIDIA(0): server, and that the module is the NVIDIA GLX module. If
(EE) NVIDIA(0): you continue to encounter problems, Please try
(EE) NVIDIA(0): reinstalling the NVIDIA driver.
Since your X configuration is requesting the glx module, the above error suggests that the nvidia driver is not installed correctly. Have you reinstalled the driver to correct this problem?
You did not use the TwinViewOrientation option to specify the orientation of your display devices when using TwinView. I doubt that this is why X is crashing, however it doesn't hurt to add it in.
The majority of the times that I've seen the following error:
(EE) NVIDIA(0): The requested configuration of display devices is not
(EE) NVIDIA(0): supported in the hardware.
its when someone is trying to run TwinView across a TV and another display device. In most of those cases the VBIOS on their videocard is not setup to allow this configuration (TV+some other display device simultaneously). Have you verified whether TwinView works with two non-TV display devices?
As a side note, it looks like the bug report that you posted was manually edited, as its missing several sections which should appear by default.
