Warnings when installing VTune and errors when installing sampling drivers on ubuntu 18.04 and 22.04

[weitao]

Dear ALL,

I am planning to use VTune to profile codes. There are some problems I met and hope to get ideas.

(1). Warnings when installing VTune:

There are one or more unresolved issues based on your system configuration a
nd component selection
You can resolve all the issues without exiting the installer and re-check, o
r you can exit, resolve the issues, and then run the Installation again.

XCB package is not installed |

DRM package is not installed |
Intel® VTune(TM) Profiler requires DRM library for graphical user in |
terface, it can be installed with |
sudo apt-get install libdrm2 on Ub |

sudo zypper install libdrm2 on SUSE

However, I have checked and ensured that both libxcb-dri3-0 and libdrm2 have been installed. Even though I can ignore these two warnings and continue to install, I am quite confused with the warnings.

Besides, since I want to profile codes with multiply cores, the sampling dirvers are quite necessary for me. However, I cannot install drivers since I cannot successfully build and load dirvers:

For the Step 5 in /sepdk/src/README.txt:

I got the problem loading the dirver to kernel:
