[Touch-packages] [Bug 1771185] Re: Secondary monitor not connecting in 18.04 LTS
So, seems I have figured out the issue (at least on my Lenovo T460s) and I think it lies with the Intel chip internal GPU. If you use display port and HDMI-->Display Port adapter it won't work. The Intel chip doesn't seem to support two DP connections at a time. But you can connect Dp & HDMI-->DVI at the same time (or VGA for that matter) & Internal display. So max is 3 displays but they need to be different techs. I can't confirm this for other laptops without external graphics cards since i don't have any more. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to libxrandr in Ubuntu. https://bugs.launchpad.net/bugs/1771185 Title: Secondary monitor not connecting in 18.04 LTS Status in libxrandr package in Ubuntu: Confirmed Bug description: I have an Acer Aspire V Nitro VN7-592G-709V with Nvidia Geforce 960M (nvidia driver v390) and a Benq W1070 projector.

Same here. Lenovo T460s (Intel only). Cannot use HDMI to Display Port. HDMI to VGA works though on the same port!! The below is with HDMI->VGA. With HDMI->DP it just doesn't recognise the display.
