error launching vtune-gui after installation.

[qgao]

Hello, 

I have the following error message after install Intel oneAPI Base toolkit. The installation is done by current user (nonroot user). 

Fontconfig warning: "/etc/fonts/fonts.conf", line 86: unknown element "blank"
[104618:0622/123508.008581:ERROR:browser_main_loop.cc(1409)] Unable to open X display.

Does anyone have any idea on this error?

Hi,

Thank you for posting in Intel Communities.

I assume you are trying to access vtune-gui from a remote server because of that you are getting this error.

Work around(Port Forwarding)

If you have a web browser on your host machine, you can follow the below process.

Step1:

To connect to a remote server, we use ssh user_name@<IP_address of that server>

Since we need to port forward our localhost to the remote server, we use the below command.

ssh -L 127.0.0.1:<port_number>:127.0.0.1:<port_number> user_name@IP

example: ssh -L 127.0.0.1:7070:127.0.0.1:7070 user_name@IP (Here I am forwarding my local host to port 7070)

Step2:

Now I need to run vtune-backend with web port 7070.

example: vtune-backend --web-port 7070 --enable-server-profiling

After running the above command, you can see 2links are generated. Copy any one of them into your browser.

If this resolves your issue, make sure to accept this as a solution. This would help others with similar issue.

Thanks,

Thank Jaideep. It helps a lot to use the profiler server as you stated to get a gui experience. I have a follow up question. When I try to deploy a VTune Agent onto the remote Linux server, I keep getting the following confusing errors: 

The vtune runs on a linux server and I am trying to deploy an agent on that server. What does it have to do with the above error?

Hi,

Thanks for accepting our solution. From the above attachment, I can see Vtune can't run on unsupported operating systems. Maybe you are trying to profile on an unsupported target. We can run the Vtune profiler on Windows and on Linux. Please go through the below attachment.
