Comment 65 for bug 1795292

I don't have words to convey my thanks to this forum (specially Kenji (dude2k5) ). I have Lenovo 330s 15ARR Laptop. Until read this forum I used NOAPIC parameter to start Ubuntu. Otherwise it is stuck on black screen. Even though I was able to start Ubuntu, touch pad doesn't work (not identified by Ubuntu), Suspend(sleep) option does not work (led light doesn't flash, screen goes black, no response after that, only thing has to do - force shut down ) and keyboard doesn't work time to time on each boot. Finally, everything started to worked correctly after substituting NOAPIC by ivrs_ioapic[32]=00:14.0.

If you think right-click still not working use this tool "Tweaks"
Use this command : sudo apt install gnome-tweaks
Check Mouse click emulation in Keyboard and Mouse.
