試したこと

• rootユーザで実施すると問題なし

• zabbixユーザで実施するち当該エラーとなる
• sudo -u zabbix DISPLAY=:99 /usr/bin/python3 sample.py

zabbixユーザでgoogle-chromeを直接実行するとどうなりますか。

Answer 1

rootでsudo実行結果は、以下です

環境変数の問題を色々調べていますが、どうもうまくいっていません
zabbixユーザは、「nologin」にしているのであまりイジりたくないのが本音です

# sudo -u zabbix DISPLAY=:99 google-chrome
