# 判断用户是否在某个组下

groups $user_name

# 如果不在，使用下面的命令加入

usermod -a -G bumblebee $user_name

# 先使用集成显卡测试

glxgears

# 再使用Nvidia显卡测试

optirun glxgears

# 报的错误（可使用journalctl查看）

[ERROR]The Bumblebee daemon has not been started

[ERROR]Could not connect to bumblebee daemon - is it running?

# 解决方案

# 步骤一：获取 PCI slot

lspci | grep "NVIDIA" | cut -b -8

# 步骤二：将上一步获取的内容写入tlp文件

vi /etc/default/tlp

# 该文件中，默认有如下内容

#=======================================================================

# Exclude PCI(e) device adresses the following list from Runtime PM

# (separate with spaces). Use lspci to get the adresses (1st column).

#RUNTIME_PM_BLACKLIST="bb:dd.f 11:22.3 44:55.6"

#=======================================================================

# 我们需要将RUNTIME_PM_BLACKLIST的注释去掉，并将值替换为步骤一的结果

# 编辑后的片段

#=======================================================================

# Exclude PCI(e) device adresses the following list from Runtime PM

# (separate with spaces). Use lspci to get the adresses (1st column).

RUNTIME_PM_BLACKLIST="01:00.0"

#=======================================================================

# 重启后就可以正常使用了optirun了

# 使用nvidia控制面板

optirun nvidia-settings -c :8
