Thunar Icons Missing

I installed thunar yesterday but on starting up this morning, I found that all of the folder icons had vanished. I'm using i3wm (but the icons were visible in i3 as of yesterday). Any idea why they might have disappeared or how I could retrieve them?

Thanks.

Try installing gnome-icon-theme-full.

I'm on Xubuntu 12.04 and using awesome WM. I can confirm that installing gnome-icon-theme-full partly solve the problem. I can also confirm it just install one single package without any excessive dependencies. But it has some side effects. It replaces some Xubuntu customised icons and makes them look weird. So I deleted it. After doing some search, I find another solution here works better. Just install lxappearance and choose a icon theme. You can also change your gtk theme using it. It's weird that xfce4-settings-manager doesn't work under awesome.

I run i3 on Xubuntu 18.04, this worked for me:

1. Create/modify the file .gtkrc-2.0 in your home directory
2. Add/edit the line gtk-icon-theme-name="gnome", change gnome to your desired icon theme.

This can be done by executing echo "gtk-icon-theme-name=\"gnome\"" >> ~/.gtkrc-2.0 in your terminal.

Try setting some icon theme with, for example, xfce4-settings-manager and running xfce4-settings-helper before starting Thunar. It helps with awesome wm.

I had a similar problem on XUbuntu 18.04 and I fixed it by opening the "Appearance" settings and going to the "Icons" tab. I selected "elementary Xfce" and the icons displayed correctly.

Note: I left "Adwaita" selected in the "Style" tab, but in the "Icons" tab the icon for "Adwaita" has a "broken icon/red ex" in it, I think this is an indication that some icon files are missing from that theme (I didn't track down why).
