[expert] Problems with gv in Mandrake Linux 7.0

[Chunnuan Chen]

Hi,
I am using Mandrake 7.0-2. I was trying to use gv to open a .ps or .pdf
file and got an error message like "unknow device: x11alpha", and the
file was not displayed. Can someone tell me what  this means and how to
correct this? Thanks.
