Troubleshooting

True color and italic support

There are lot of discussion about true color and italic support in the terminal. Below the list of relevant posts.

• morhetz/gruvbox wiki -- Terminal specific
• neovim/neovim -- FAQ
• XVilka/TrueColour.md -- Colours in terminal
• How to enable true-color for neovim, tmux, and gnome-terminal
• neovim/neovim -- Italics aren't displaying properly #3461
• neovim/neovim -- Get funny chars on terminal #3462

All in all the solution for me involved to at least:

• Upgrade to Ubuntu Xenial 16.04, to get newest Gnome Terminal and Terminator/gtk3 on recent VTE.
• Upgrade to tmux 2.2 (only if using tmux).
• Do a total reset of the account configuration.
• Fiddle a bit with the terminfo (still not sure what was the exact recipe though).
• Use gruvbox as theme (not solarized, which does not work in terminal).

To test, first verify that the color theme works correctly in gvim.
