i relatively inexperienced ubuntu user: time ago updated ubuntu 14.04 lts , after restarting system, both monitors (connected dvi , hdmi ports) reported signal lost. able monitors working again booting old kernel.

however, support kernel ended in august 2016 , should find solution works latest kernels. hence, decided upgrade ubuntu 16.04.1 lts lead situation monitors lost signal when installed/boot computer. managed signal screens setting thenomodeset option in grub menu.

unfortunately, both monitors show same view not have.
