Cannot view file, Linux Mandrake 9.2

[Ladislav Mecir]

Hi all,

a newcomer to the list here. I am using LyX to my satisfaction for quite 
some time.

Recently I switched to Mandrake 9.2 from the 9.1 variant a here is what 
happened:

it looks, that the user interface has been switched to QT (from xforms). 
When I tried to adjust all local settings I was disappointed, because I 
didn't succeed to read the Czech Tutorial (CS_tutorial) file coming with 
LyX in the Czech alphabet. I didn't find a place where I could adjust 
the font setting to ISO 8859-2 for both the user interface and for the 
document display.

When I tried to view the pdf output of the Tutorial I saw the following 
message instead:

LyX: Cannot view file

No information for viewing PDF (pdflatex).

I decided to download the 1.3.3 from the LyX site and compile/install 
it. For the user interface I have chosen the xforms and therefore I am 
able to see the contents of the CS_tutorial file in Czech properly, but 
the file viewing problem remains.

Thanks for helping

Ladislav
