I've installed moodle 1.8.2 from the Ubuntu repositories on a 64 bit system running Ubuntu 8.10. Moodle server works fine. With TeX filter enabled I can display equations within the text using the tags. But math looks very ugly - in fact is hardly readable! I have a 1280x1024 LCD monitor with 86 dpi. I tried playing around with density parameters in latex.php and defaultsettings.php - that changes only the image size (default "density" is 120) but not the resolution. Also, if I want to print out the glossary, for example, all the math is not printed at all. What are the relevant config files where I can change these settings?
