Vesa driver setup for nVidia was created by Ozcnc
I've started by stopping the x server.(no problem)
I run the sudo xorg -configuration.(no problem)
I run sudo mv xorg.conf.new /etc/x11/xorg.conf (Fail file does not exist)
I am running the commands as root user.
Any suggestions.

what distribution and version are you using?
The newer linux distributions may not come with a xorg.conf. I got the vesa drivers running on my ATI by blacklisting the radeon drivers. You probably can do the same. Really depends on what you are running though

10.04 2.5.3 ??? 122
Not sure will have to boot it up to check.
Blacklisting is a good idea but I'm so green at Linux it's not funny.
I will happily try all the suggestions.
currently my latency is at 590000 and it should be at 7500+.
Cheers

what else have you checked? With numbers like that, it's not unlikely to be a video problem, but you can't rule out SMI or USB or other driver issues.

Your right I have a feeling that it is more likely SMI.
I have started looking into SMI but I've only spent about two hours so far getting familiar with everything in Linux.
The latency figure are around 7500 for about two seconds and then jump to 470000 and after reset of the highest latency it will be low for a second and then be high again.

Hi
Have a read of these FAQs before you jump in any particular direction
www.linuxcnc.org/index.php/english/forum...-the-latency-problem
www.linuxcnc.org/index.php/english/forum...me-latency-solutions
Especially run the realtime latency test described to find out when the spikes are occuring
Unless the spikes are only every 32-64 secs and you have an affected Intel chipset, it is not SMI
If you have a nvidia graphics card, then make sure you are not using the proprietary drivers, you should be using open-source ones, nouveau probably.
(package xserver-xorg-video-nouveau-xxxx)
vesa is a very last resort, it is ancient and does not support much in the way of screen resolutions
For any specific help, you will need to tell us what the computer and its components are, in detail
lspci -k will tell you what kernel drivers are being used
lspci -vv will give you detailed info re all your PCI cards as well as the chipsets on the MB
regards

Thanks,
I have read through the links you have attached and will attempt to process the latency tests with per second display in terminal.
I don't think I have the spike as noted but will verify this with the test suggested.
I will also check the specs and hardware and will post them here.
Thanks again.
