Ubuntu 16.04 附带相当更新的 Intel Graphics 驱动程序。Intel PPA 提供的次要修订更新几乎没有什么好处。
话虽如此,如果你仍然想使用该工具,那么你应该遵循全部说明下载页面,即
签名 - Ubuntu:
wget --no-check-certificatehttps://download.01.org/gfx/RPM-GPG-KEY-ilg-4-O - | \ sudo apt-key 添加 -
sudo apt update && sudo apt full-upgrade
无需再次运行图形安装程序。
附加信息(题外话):删除 Ubuntu Tweak PPA,因为它不适用于 16.04。搜索重新打包的 xenial (deb) UT 安装程序。
