I have a Google Pixel (2015) with Fedora 24 installed. This has an Intel HD 5500 graphics card.When I plug in two 4K monitors (one in each USB-C port) the displays work properly.  However, if sometimes when I wake from suspend or sometimes when I boot with both monitors plugged in, the computer freezes.Whether it freezes or not, the last entries in the graphics logs are always setting the mode:# journalctl --boot=-1 _COMM=gdm-x-session | tail -3/usr/libexec/gdm-x-session[2678]: (II) intel(0): resizing framebuffer to 7680x2160/usr/libexec/gdm-x-session[2672]: (II) intel(0): switch to mode 3840x2160@60.0 on DP2 using pipe 1, position (3840, 0), rotation normal, reflection none/usr/libexec/gdm-x-session[2672]: (II) intel(0): switch to mode 3840x2160@60.0 on DP1 using pipe 0, position (0, 0), rotation normal, reflection noneWhile the computer doesn't appear to respond to input, it does acknowledge a power-button press that turns off the computer:# journalctl --boot=-1  | tail -1systemd-logind[855]: Power key pressed.None of the other default syslog output shows anything abnormal.Since none of these logs show anything wrong, what can I do to further debug this?  Are there other logs that I can check (e.g., other _COMM flag) or is there a way to enable deeper logging?
