Public bug reported: Brand new Shuttle PC direct from factory, Kaby Lake with Intel HD620 (which uses part of the 16GB RAM) with Bionic-Beaver-latest install last month (september 2018) for Cancer Research. The application is Libre Office 6.0.6.2 with very many linked graphics per sheet (nearly all columns used for some analyses).
The Display Port plus HDMI1 plus HDMI2 outputs are all simultaneous 4K (unlike the Intel HD600) which is ideal for this type of research work (all three monitors are very large 42"+). One application across all three monitors to compare any detail. Else than a presentation luxury, it's where the whole work was headed since four years - like engineering, the size of the surface of a table. The Xorg interpretation that shows up in xrandr is default limit at 8192x8192 but the user doesn't know it. Bionic Beaver "settings" allows attempts to move and modify, illustrates the effort, finds then loses the third screen, crashes if the user persists and doesn't mention the limit. It works (and very well) only if two displays are left-right and one is placed underneath or over the top. It is possible to find that out by trial (and lots of error). According to askubuntu, the Intel gen 6 and up (or thereabouts) all support 16384x16384. One user confirms Ubuntu 18.04 offers that full boundary if the driver is Nvidia but not if it's Intel i915. The user also stated that this was "a known problem with ubuntu17 and gnome and fixed" but I can't find any reference about that, nor how to do it. A suggested source code "Intel side" patch was commented on this askubuntu page last week https://askubuntu.com/questions/1045664/kubuntu-18-7th-gen-intel-graphics-incorrect-max-resolution Intel sites suggest contacting Ubuntu and the Vendor first. So I post the bug here. [By the way, the other PC was on 18.04 Lubuntu with Libreoffice 6.10 and crashed or froze about ten times per day (Open GL or without). This new PC and the previous are now both with Bionic Beaver and Gnome and not once has either hesitated, not one single stoppage of any type. Absolutely amazing. Wonderful. The stability is crucial and I hope developers and Canonical receive praise - an important decision in favour of users. My suffering is ended. Thankyou].
