Ubuntu 15.04, Dell Inspiron
- Intel Corporation 3rd Gen Core processor Graphics Controller
- NVIDIA Corporation GK107M [GeForce GT 640M]
Monitor: BenQ EW2440
What I am trying to do?
Connecting my laptop to the BenQ monitor to extend desktop space. The cable that I have used is HDMI at both ends due to the fact that my laptop has no VGA port.
What I have tried?
Successfully installed Intel Graphics Controller via this link
https://01.org/linuxgraphics/downloadsI have installed the drivers using Intel Graphics Installer for Linux* 1.2.0
Tried installing Nvidia proprietary driver via 'Additional Drivers' System fail to boot into GUI. Check error in /var/log/Xorg.0.log and it says "nvidia" screen is not configured. Tried adding "nvidia" configuration as below
Section "Device" Identifier "nvidia" Driver "nvidia" BusID "PCI:2:0:0" EndSection Section "Screen" Identifier "nvidia" Device "nvidia" EndSection
but everytime on reboot, xorg.conf is reset back. Tried the solution in this link http://ubuntuforums.org/showthread.php?t=2220552 by commenting inside the gpu-manager.conf as apparently, gpu-manager might be overwriting the file. However, even after commenting out, it is the same.
- Reverted back to Nouveau driver and checked System Settings->Displays. It does show the BenQ monitor. However, the monitor is blank. Image as below.
