LyX ⇒ troubled after upgrading system

[swordless]

hello everyone.
I'm working on the Ubuntu 10.04 & Lyx 1.6.5. Then I upgraded my kernel to version 2.6.32 - 26 several days ago. Then everything seems wrong, the Lyx cannot DVI or make pdf even the tutorial file in Help -> Tutorial. Here is the err information:
Package babel Error: you haven't loaded the option english yet.

I tried to reinstall Lyx in the software center, but it didnt work. I think it's much more concerned with some config files of the system. So is there any suggestions that can solve this trouble~

I can't see how a kernel upgrade can have any impact on LaTeX. Please, post here an example .lyx file which shows the problem.

I can't see how a kernel upgrade can have any impact on LaTeX. Please, post here an example .lyx file which shows the problem.

I think that the problem is here:

(/usr/share/texmf-texlive/tex/generic/oberdiek/ifpdf.sty
Package: ifpdf 2009/04/10 v2.0 Provides the ifpdf switch (HO)
Package ifpdf Info: pdfTeX in pdf mode not detected.

I don't think so. The problem is that \selectlanguage{english} command is set in the source you provided (immediately after \begin{document}), but babel package isn't loaded at all (and all errors are babel-related). So, either go to Document > Settings > Langauge and set the language or put into the preamble the following:

Code: Select all

1
\usepackage[english]{babel}
 
 
הההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההה
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

And, BTW, it is better to include a .lyx file instead of LaTeX source, just in case that LyX messes something up (and it does from time to time). Note that you'll need to put the file into a ZIP archive prior to attaching.

I insert the preamble, and it worked.
