I want to get display info of my current system.So I used the following command:
sudo cat /sys/kernel/debug/dri/0/i915_display_info
It displays me : cat: /sys/kernel/debug/dri/0/i915_display_info: Operation not permitted
The above command works in various ubuntu systems (16.04-64 bit).But it is in my system having the same ubuntu 16.04-64 bit;it gives error.
My System Info:
Kernel version:4.15.0-42-generic
Distributor ID: Ubuntu
Description: Ubuntu 16.04.4 LTS
Release: 16.04
Codename: xenial
Edit:The output of sudo -l
Matching Defaults entries for test on test-NUC7i5DNKE:
env_reset, mail_badpass,
secure_path=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin
User test may run the following commands on test-NUC7i5DNKE:
(ALL : ALL) ALL
Things I have tried:
sudo -s and gave the command without sudo,it gives me the same error.
I have tried searching to solve this issue in various forums but couldn't find one.Any inputs will be really helpful!!
Thanks in advance.
