ubuntu 14.04.1 linuxcnc help

I found a more recent kernel and patch I would like to try.
4.1.5... Although I'm not aware of a a pre existing working config file.

You don't need another config file, the settings do not change with kernel versions.

I have built all the way to 4.x.x-r11 with the same config.

Just set it to 64 bit and build, all the settings necessary for rt-preempt are there.

regards

There were problems with each config i made each diffrent. is there a way to see the config of my current build so i can compare each and find something that will be optimal?

running any linuxcnc kernels on a Laptop are probable causes for problems , is their a reason you wish to use ubuntu , and not change to debian as per the live cd , there are reasons changes were made .
theirs no real need to run the latest and greatest kernels , but laptops are the worst for subtile changes , as they are usually cutdown and facilitys removed etc .

i have successfully built kernels to 4.1.10-rt11 with rt-preempt .
abeit this is using a desktop and debian 7

Each kernel you build has a config file copied into /boot

/boot/config-4.1.10-rt11 for example

Because they are text files, you can just compare them with diff

There is no need to change anything in the config that was with the instructions you got, except the 32 / 64 bit build

I didn't pick up on your single mention of 'laptop' earlier.

It will not stop you running sims on rt-preempt, but don't expect a great latency for machine control.

Unfortunately the .config from the instructions was a fail. upon booting there were some graphical anomilies and at the password prompt box, when entering my password, it would flash and restart the computer.

This is why I was going to compare the files.

There is no great reason to do this on ubuntu i suppose other than to try to streamline the workflow as best as possible in an environment I'm used to and comfortable with. ubuntu has a bit more of a gooey feel to it.

Having the machine controller on a laptop is just a matter of portability. I have a small mill here at the house and I have access to a much larger wood router elsewhere I can use. the man that owns it said his previous employee took the computer that ran it, and I was welcome to use it.

I will look into why the config did not work and I will post what I found. Wish me luck lol

it wont be the config at fault , but the fact of needing specific drivers for your laptop , the config works fine on a desktop .
this is as i said before , the pitfalls of working with laptops , with specific needs for graphics etc , and power management
