[daip] tv server problems on ubuntu 11.04

[Sharmila Goedhart]

Hi

I've got an odd problem that isn't covered in your FAQ. I've just gotten a
new computer and been installing software on it.  The aips tv server did
appear to be working when I first installed aips, but after that I did a
system update and installed other software and now the aips tv and tekserv
does not appear at all even though the startup messages all look normal. I
even reinstalled aips and still no luck. I have verified that the colour
depth is 24 bit.

I had a suspicion that this might be a problem with the nvidia driver (560
Ti  graphics card) so I disabled it. The screen then went into some really
horrible low resolution on gdm restart, but the tvwindow does indeed appear.
 Then I tried using the nvidia driver with the same low resolution and the
tvserver worked.  So I thought I had a workaround. Not ideal but ok.
Unfortunately it turns out that there is a problem with the nvidia driver
that is bundled with Ubuntu and my graphics card overheated, causing my
computer to shutdown. So I had to install the binary driver from nvidia.
 Now I can't get the tvserver to appear at any resolution, and since I had
to disable the nouveau driver in order to install the nvidia driver I can't
go back. I also think that I really need to make sure I am using the correct
nvidia driver so my graphics card does not burn itself out.

Any guidance on where to look for the solution would be appreciated.

Regards

Sharmila
