I have successfully installed plan9port on Ubuntu Linux. I managed to change the font for sam when I run it. I have set this in my .bash_aliases file:

alias sam="export font=/mnt/font/GoMono/11a/font && sam"

However, the same code does not work for acme. If I add this alias:

alias acme="export font=/mnt/font/GoMono/11a/font && acme"

then acme starts, but the font is not GoMono. 

I have tried this with other fonts too.

I would appreciate any help with this.

BTW I am running sam/acme directly from the bash shell.
