I have a very disturbing problem running LyX with Ubuntu 12.04 on my Dell Inspiron. Ever since I purchased this laptop and installed Ubuntu 12.04, it periodically freezes and nothing can be done to wake it up except a hard reset. That by itself is not a huge deal as I am always saving important files, etc.
However, three separate times now, when I am working in LyX and the freeze happens both the file that was open in LyX and the backup file (filename.lyx~) are completely destroyed. After reboot, the files still appear in the file system but are of size 0 kb.
Needless to say, this is a dire situation to encounter and requires constantly backing files on a flash disk or remote machine.
Has anyone else had this problem? Or, any ideas what might have happened to those files? Perhaps LyX backs them up somewhere else temporarily, and they are stuck there when the OS crashes?
I couldn't find a single crash log or any other useful information. But I will gladly post other technical details if they are of use in diagnosing the problem.
