我的系统:Ubuntu 22.04 内核:5.19.0-46-generic
我的显卡:Intel i7 11代集成Intel Iris Xe
最初想解决的问题:安装正确的官方驱动,实现双屏。
我遇到的问题:按照Intel官网提供的驱动安装方法进行安装,一切正常,一直到Configuring render group membership这一步,官方给出的方法是
stat -c "%G" /dev/dri/render* groups ${USER}
可是我发现我的/dev下面完全没有dri这个目录,后面还是按照流程,将我的用户加入了render组,这证明我的系统是有render的,但是不知道在哪里,并且最后,驱动安装也不成功,但是除了上面这个意外,什么错误都没有,都顺利的进行完了,结果到现在系统仍然是下面几幅图的状态,请哪一路大神帮忙看一下,谢谢!
还有一些辅助信息如下:
