Latency Test not opening 10.04

Hi all - I am a noob to EMC2 & Ubuntu. Installed fresh from live CD (3 times). In the apps drop down CNC appears and in this list at the bottom is the latency test title. I click on it and nothing happens - no latency test app opens. Clicking on EMC works.
What to do?

will the latency test work from stepconf

You can try the latency test from a terminal window ...

Just open up a terminal window and type in

latency-test

wiki.linuxcnc.org/emcinfo.pl?TweakingSoftwareStepGeneration

However I would download and try the 8.04 live CD first.

The 8.04 version seems to work better on some computers and the 10.04 seems to work better on other (newer?) computers.

Thanks cncbasher and Rick G - I am not certain how to launch stepconf but I did try the 'latency-test' in terminal and received the following:
centaur@centaur-desktop:~$ latency-test
insmod: error inserting '/usr/realtime-2.6.32-122-rtai/modules/rtai_hal.ko': -1 Operation not permitted

Hope this is not too long for a post - does this help to solve the problem?
Thanks

Can you post the output from the dmesg command?

Sounds like the dreaded "No local APIC present or hardware disabled" problem

Hello Peter - I am new to Linux and I am assuming you want me to simply run the 'dmesg' command in the terminal window. I did this and it is 100 miles long - anyway, here it is and I have no idea what any of it means.
Thanks

may need some grub/BIOs setup tweaking as well

Hi BJT and PCW - I see your names a lot on this forum and you are definitely an asset.
BJT - the mobo is actually an older unit from my pile of stuff. It is an MSI K7T266 Pro2-A and is in the DDR ram erra. The CPU is a vanilla single core 1.0ghz AMD Athlon. I chose this mobo because it has a PP and EPP selectable in the BIOS.
PCW - I looked in CMOS and sure enough the APIC was in the disabled setting. I enabled it and rebooted - voila! I have latency test now. BUT - now I suddenly have no USB when I plug in my flash. (I mentioned this in post elsewhere in this forum)
Now to shift focus for a moment - the jitter I am seeing is quite high - 84,144 on the servo thread. I just purchased a 7i43 with a 7i33 and I am wondering if this mobo is not going to perform for what I will need. It would be nice to have my USB back but if the mobo is not going to do the job there may be no point in the pursuit of this issue.
I'm getting the feeling that I'm in over my head.
Thanks

No idea what the USB problem is from, but anyway...

84 uSec latency is probably OK for a servo system, and your latency figures
may be improved if you look at the wiki suggestions for improving latency.

As others have suggested, you might try the Ubuntu 8.04 release as it often
does better on older motherboards.
