Please make sure you are booted into the RT kernel. You can check which kernel you are booted into by typing uname -r

oPiZiL commented 7 years ago

uname -r 3.16.0-77-generic So, how could I boot into RT kernel

oPiZiL commented 7 years ago

I modified

/etc/default/grub GRUB_HIDDEN_TIMEOUT=0-->GRUB_HIDDEN_TIMEOUT=10

then I restart the system. The screen goes grey, So I press ESC. I selected xenomai mennuentry, BUT I can't go into graphics desktop.

It sounds like you may be missing the right graphics driver for your card. Are you using a dedicated graphics card or on board graphics?

oPiZiL commented 7 years ago

It's an onboard graphic card.

one more question:

If I upgrade the Ubuntu 14.04 to 16.04, would it work in RT kernel?

yapatel commented 7 years ago

Typically the OS and the kernel are not dependent upon each other. That being said, there could be kernel dependencies that cause issues.

If you have 14.04 working, then there is no significant benefit to jumping to 16.x. Both are LTS versions and function for RTXI.
