我有ASUS K555LA
optimus nvidia(740M)。我已经安装了nvidia-340
,nvidia-prime
一切正常。现在nvidia driver
启用了,我的第二台显示器一片漆黑(好像没有显示信号)。Nvidia-settings
无法检测到第二台显示器。在系统设置的显示中,我可以看到第二台显示器,但无法启用它。当我尝试启用第二台显示器时,它总是挂起或崩溃。
第二台显示器在驱动程序下工作正常intel
。之前我用过bumblebee
,nvidia-340
工作正常。现在 nvidia-prime 无法处理辅助显示器。我没有更改任何驱动程序配置。双显示器在登录屏幕 ( lightdm
) 中也使用nvidia
驱动程序工作正常。
