If you have KDE just go to http://www.sbl-site.org/educational/...SBLHebrew.aspx
and download the font then http://www.echoofeden.com/digest/sla...e-under-linux/
please do change that keyboard toggle shortcut to ctrl alt up because ctrl alt k isn't recognized when you're typing Hebrew!
Other methods didn't work for me- but this way should take you 10 minutes. I have KDE, same as the writer in the above post, but I'm sure other desktops will work fine. Shalom
