No display found + fan problem
 
I run ubuntu server and 2 weeks ago I made upgrade to ubuntu Lucid v.10.04. Since then the fan is very noisy. At the beginning I thought, that the noise comes from computer's fan, but now I suspect my nVidia Corporation GT216 [GeForce GT 220] (rev a2).
First of all, Ubuntu driver by default had some problems and I replaced it manually by NVIDIA-Linux-x86_64-195.36.24. Now, I have this error in Xorg.log file:

(**) May 16 14:08:00 NVIDIA(0): Enabling RENDER acceleration

(II) UnloadModule: "wfb"
(II) UnloadModule: "fb"
(EE) Screen(s) found, but none have a usable configuration.


Actually, no screen is attached to the computer, but I use graphical remote control (NX server) to work with it. How can I fix this problem?
I hope, that a solution of this problem will solve fan's problem as well.

Thank you.

Re: No display found + fan problem
 
So, I found this realize note:
Now, the NVIDIA X driver will not automatically pretend that any CRTs are connected. If the X driver does not detect any connected display devices, the X server will fail to start.


So, my machine doesn't have any screen attached, because I use remote control FreeNX and NVidia driver will never start, because it can't find the screen. I'm right?
By the way, I found that
Option "UseDisplayDevice" "none"
can solve screen's problem, but it doesn't not apply to GeForce GT 220.

Please help!

If you want to force behavior similar to previous driver versions, which assumed that a CRT was connected if no displays were detected, you can add this line to the "Device" section of xorg.conf:

Option "ConnectedMonitor" "CRT"

Bingo!
It fixed my problem - the fan is quite and no errors in Xorg.log file.

Thank you danix.
