Nvidia Ion Asus Eee PC Seashell 系列 1215n 和 Optimus

我正在使用 ubuntu，lubuntu，kubuntu：

Linux sysop 3.19.0-33-generic #38-Ubuntu SMP 星期五 11月 6 日 18:18:12 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

在配有 Nvidia Ion 卡的 Asus Eee PC Seashell 系列 1215n 上。安装以下软件包后：

sudo apt-get install nvidia-346 nvidia-settings nvidia-prime

lightdm gdm sddm 无法启动。如果我想获得图形环境，我必须：登录 tty，然后执行以下操作：

sudo nvidia-xconfig
startx

有人可以帮我让桌面管理器工作吗？

使几个桌面管理器重新工作：

sudo apt-get install --reinstall  nvidia-346 nvidia-settings nvidia-prime
sudo nvidia-settings

检查英特尔省电模式。保存并写入/覆盖配置。重启。Lightdm 现在可以正常工作了。我认为这是 xorg 配置的问题。虽然我的问题只涉及桌面管理器（如 gdm lightdm），但我认为我还没有修复任何硬件加速。但我得到了我需要的东西。希望这能有所帮助。
