I successfully installed Ubuntu 14.04 on my macbook pro 9,1. Everything is now working correctly. Except I am unable to plug in a second screen.
If I plug in another screen :
At system Boot: I get no display(black screen) after the initial console messages related to system start. Though in the black screen if I press
type my username->
type my password->
type sudo reboot->
type password. Then I can still reboot successfully.
At runtime: I can see the second screen being detected by nvidia-setting page. But still the second screen has no display
I have tried the following:
- Change the drivers to Nouveau drivers
- Use the Nvidia 331.38 drivers
- Install BumbleBee: This gave me a black screen on my main monitor and I had to reinstall the Nvidia drivers after removing bumblebee. I was using this link for installing bumbleBee.But after rebooting my display goes away.
the output for
lspci | grep VGA is:
01:00.0 VGA compatible controller: NVIDIA Corporation GK107M [GeForce GT 650M Mac Edition] (rev a1)
Please advice how I can have the second screen on my Macbook pro. My current driver version : 331.67
Updates: 1. When I connected DisplayPort-to-HDMI converter to my HDMI TV screen the second display started working as it is. I then tested my old monitor(which only has D-sub connector) using the chain:
DisplayPort-to-HDMI adapter-> HDMI-DSub adapter->DSub input of my monitor.
After changing to the correct resolution, my monitor is now acting as a secondary display. So I guess the problem is either : 1. With Display-port to D-Sub adapter I have(its china made) 2. OR there is a problem with all the Display-port to D-Sub adapters. I will test my friends adapter and post here later.
