Ubuntu 16.04 cannot detect second monitor - Ask Ubuntu

i have msi gs73vr stealth pro. comes windows 10 , put ubuntu 16.04 on it. cannot seem external monitor work ubuntu. have tried every solution found online has resulted in me installing , uninstalling nvidia drivers many times no avail. how can fix issue or figure out causing it?

edit:

laptop info
processor: intel® core™ i7-6700hq
graphics: nvidia gtx1060
driver: nvidia binary driver - version 375.20
os type: 64 bit

with intel skylake processor others have reported freezing when external monitor connected. found upgrading kernel 4.4.25 solved problem. since kernel version outdated current version 4.4.33 better.

to install 4.4.33, use:

cd /tmp wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.33/linux-headers-4.4.33-040433_4.4.33-040433.201611180742_all.deb wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.33/linux-headers-4.4.33-040433-generic_4.4.33-040433.201611180742_amd64.deb wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.33/linux-image-4.4.33-040433-generic_4.4.33-040433.201611180742_amd64.deb sudo dpkg -i *.deb sudo reboot 

to improve question can list nvidia card model number, ie gtx 1060 , nvidia driver in use, ie 367.57. obtained driver, ie system settings -> software & upgrades -> additional drivers or nvidia ppa, etc.

the more information provide, better chances of success.

edit 1 - try intel settings

isolate if it's nvidia problem or intel system problem turning off nvidia , using intel graphcis. run nvidia's x server settings dash or terminal typing nvidia-settings.

change settings so:

save, quit , reboot.

if external monitor doesn't work on reboot need focus on intel microcode, driver configuration, etc. if external monitor works on reboot need focus on nvidia driver 375, x-org serttings, etc.
