Hi, I've just installed Kile on Ubuntu 17.10 and I can't get the livepreview to work. The option in the kile-settings is enabled but the entry in the build menu is grayed out. Also no option to show the document viewer in the settings tab is available. kilerc does contain the LivePreview-PDFLaTeX item and for what I can tell it is correct, though this item is not listed in the tools->build section of the kile-settings. I'm a bit lost as to how to debug this. Anyone got some ideas on how to go on?...
