我有一台华硕 Ul30vt，配有英特尔/英伟达混合显卡。我可以正常加载英特尔驱动程序，但加载英伟达显卡却很困难。我尝试了许多不同的解决方案，包括使用 ubuntu 受限驱动程序和英伟达网站上的驱动程序。不过，我会描述我目前的情况，看看这些信息是否足够。如果需要更多信息，请告诉我。
目前当我跑步时
jockey-text --list | grep nvidia
它返回以下内容
kmod:nvidia_current - nvidia_current (Proprietary, Enabled, Not in use)
kmod:nvidia_current_updates - NVIDIA binary Xorg driver, kernel module and VDPAU library (Proprietary, Disabled, Not in use)
我也可以跑
modinfo nvidia_current

此配置目前失败（如果我将其更改为使用带有英特尔驱动程序的 Screen0，我就可以正常进入 lightdm）。当我选择 Screen1/nvidia 时，我收到以下错误

我尝试在 xorg.conf 中输入“nvidia_current”来查找设备名称，但它失败了，并说找不到“nvidiacurrent”模块。
本质上，我不确定需要在 xorg.conf 中放入什么来指向我的系统知道存在的 nvidia_current 模块。
谢谢您的帮助，如果需要更多信息请告知。
答案1
这是一个老问题，但仍然没有答案——希望这对某些人有帮助。
确保你已经安装了内核的头文件 - 如果没有这个，你将无法构建 nvidia 模块。
sudo apt-get install linux-headers-`uname -r`
然后，运行
sudo dpkg-reconfigure nvidia-current
毕竟，跑
sudo nvidia-xconfig
或者恢复您原来的 xorg.conf。
答案2
更新内核的标头就成功了！我曾尝试运行，sudo nvidia-xconfig但没有成功，但全新安装 nvidia 并更新标头修复了文件的生成。请参阅下面的全新更新命令：
sudo apt-get --purge remove nvdia-*
sudo apt-get install nvidia-current
答案3
尝试重新生成 xorg.conf 以测试它是否能解决您的问题。
首先将当前文件移至 xorg.conf.old，然后执行sudo nvidia-xconfig以重新生成它。
我还建议您运行（在上述操作之前）sudo dpkg-reconfigure nvidia-current以确保驱动程序配置良好。
答案4
这台笔记本电脑（华硕 UL30VT）不是 Optimus 型号，尽管它有混合显卡。如果我没记错的话，它有一个可以通过软件（BIOS？）控制的硬件多路复用器。
尝试：
- 删除
/etc/X11/xorg.conf文件，设置应自动检测 - 重新安装 nvidia-current：
sudo apt-get install --reinstall nvidia-current - 重新启动进入 BIOS 并检查是否有强制使用集成或独立显卡的选项
- 启动 Ubuntu
- 检查 nvidia 卡是否正在使用（日志文件位于
/var/log/Xorg.0.log）
