Like a few other people, I am having performance problems with Lyx
1.4.3. I started using it about a month ago and I really like the Lyx
method of working. I would appreciate any tips that anyone on the list
can offer.
1.3.7 (installed using the Ubuntu package management) works fine.
However, 1.4.2 and 1.4.3 (both built from source) suffer from sluggish
screen updates and high CPU usage. The program is sluggish but still
usable so, I'd like to keep using 1.4.x as I like some of the new
features. I am gathering notes for a book project and I currently have
about 12,000 words. I presume that I could move back to 1.3.x if the
program becomes unusably sluggish in the future?
This problem existed on Ubuntu 5.10, Ubuntu 6.10 and Kubuntu 6.10LTS. If
I bring up the KDE process monitor, it would seem that the CPU usage
(when I am highlighting text in Lyx) is divided between Lyx and X.org.
The problems persist with either the stock NVidia support that comes
with Ubuntu or the latest drivers from the Nvidia website.
The problem seems worse when I highlight text with the mouse. Moving the
mouse around when highlighting text takes the processor usage up to 100%.
My machine is a PIII 800 w/384 megs.
Nvidia MX440 64mb.
Kubutu 6.10LTS KDE 3.5.2
1.3.x works fine as does 1.4.x if built for the XForms front end. 1.4.x
with the GTK front end shows similar performance problems.
I have attached the output from ./configure --with-frontend=qt
--with-qt-dir=/usr/share/qt3/ >lyx143qt_config.txt to this email.
Thanks in advance for any help that people can offer.
