the HDMI port of my lenovo ideapad 500s with Ubuntu 18.04 LTS is not working.
I also executed the xrandr command, but only the primary monitor is detected.
How can I solve my problem?
How can I check that HDMI is not broken?
Thanks in advance.
When I try to install tensorflow package with pip3 on Ubuntu 16.04 I obtained this error message:
The directory '/home/federico/.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag. The directory '/home/federico/.cache/pip' or its parent directory is not owned by the current user and caching wheels has been disabled. check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag. tensorflow-0.7.1-cp34-none-linux_x86_64.whl is not a supported wheel on this platform.
How I can fix the problem?
