Re: terminal.app fails also on 8-bit vnc4server with "Unrecognized color masks"

It doesn't work on 32-bit vnc4server.

So, on a fresh Ubuntu8.04 on 32bit x86 hardware, terminal.app on 
vnc4server works only at 24bpp.

I noticed that at 32bpp thunderbird display is garbled : all text and 
icons are replaced by black rectangles. Color backgrounds, lines, etc 
are ok. Just in case this is useful to you.

Regards.
