drivers - Ubuntu 16.04 Triple Monitor on Lenovo W530 - Ask Ubuntu


wondering if has had luck this. currently, working under 14.04, nvidia-331 , ubuntu-drivers-common_0.2.91.5. tried https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers, suggested in ubuntu 16.04 dual card triple monitor setup, without success. 

lspci | grep -i vga 00:02.0 vga compatible controller: intel corporation 3rd gen core processor graphics controller (rev 09) 01:00.0 vga compatible controller: nvidia corporation gk107glm [quadro k1000m] (rev a1)

cheers,

using https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1556459 , few frustrating hours, here solution:
1- disable prime in bios
2- select discrete graphics in bios
3- update /etc/default/grub include
grub_cmdline_linux_default="thinkpad-acpi.brightness_enable=1 acpi_backlight=vendor"
4- update-grub
5- apt-get remove --purge "nvidia*"
6-add https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers ppa
7- apt update && apt -y upgrade
8- select nouveau display driver, under software & updates, additional drivers tab

after reboot, able use lvds, vga , dvi. snag contrast cannot controlled via keyboard, due step 3, above. work around, do:
echo x | sudo tee /sys/class/backlight/nv_backlight/brightness, x between 0 cat /sys/class/backlight/nv_backlight/max_brightness.
far, has been experience, glxgear showing 60 fps , fan running quieter. cheers,
