 |
|
Hello,
I am updating an ebuild, and the tests need access to the video card. When running the tests in a chroot, they all fails with the error
| Code: |
libEGL warning: failed to open /dev/dri/renderD128: Permission denied
libEGL warning: failed to open /dev/dri/renderD128: Permission denied
libEGL warning: failed to open /dev/dri/card0: Permission denied
|
It is a python ebuild, and I am using virtx to run the tests.
Everything should work but it does not, I am puzzled.
Do anyone has an idea ? |

| Welcome to the forums. On its own, chroot should not cause this. However, some kernel hardening features may interpret chroot as a broader request to lock down the contained process. What is the output of emerge --info; namei -l /dev/dri/card0 while in the chroot? |
