Recent updates to x2go seriously broke it on Ubuntu 17.10. After the
update, the first attempt to login resulted in giant fonts, giant terminal windows, giant everything. I went into System->Preferences->Look and Feel and then Fonts, then Advanced and found DPI had been set to 201, set that back to 96 and font size and terminals returned to normal, but I can't use the bottom half or approximately right third of my desktop now.
