Nvidia Ubuntu 15.04上的8600 M地球力无法启动(MacBookPro 4,1)

Question

我的MacbookPro 4,1和Nvidia Geoforce 8600 M一起工作，在Ubuntu14.10下找到。我做了升级到15.04，但没有一个桌面。我的弹出式弹出无法配置。

我看到一个帖子，建议我应该得到最新的Nvidia驱动程序的遗留支持，这是Nvidia 340.76 (来自xorg-edgers/ppa)。它安装没有错误，但现在，当我启动时，我得到了一个临时控制台登录，取代了一个带有闪烁光标的黑色屏幕。控制Alt-F1不工作，但我可以在其中。

Xorg日志显示：

Answer 1

建议在安装新驱动程序之前进行清除。例如，对于343：

sudo apt-get remove --purge nvidia*
sudo service lightdm stop
sudo add-apt-repository ppa:xorg-edgers/ppa
sudo apt-get update
sudo apt-get install nvidia-343
sudo service lightdm start
sudo reboot

你对此不清楚，所以我只是检查一下。

如果你没有想到任何东西，你知道你可以重新安装Ubuntu，但首先清除驱动程序。根据我的经验和我所看到的，似乎安装在系统上的nvidia驱动程序往往会破坏升级。

等待更好的帮助..。
