previewer like DVISCR (emTeX) for Linux available?

[Thomas Martin]

Hello,
until now I have been working under DOS using the emTeX distribution which
includes a comfortable previewer (DVISCR).
Now I started using Linux and XDVI but I am wondering if there
is a previewer having a ruler, text search and zoom capabilities, colour
options etc. like DVISCR. 
Any recommendations?

Thanks!
