SAN FRANCISCO ­— Intuit Inc., Lucasfilm and Pixar will pay a total of $20 million to settle a class action lawsuit on behalf of ex-employees who claim the companies illegally suppressed salaries by striking pacts with other high-tech businesses to not raid each other’s ranks.

Plaintiffs lawyers asked the court on Saturday to grant preliminary approval of the settlements and certify a settlement class of former employees who did technical or creative work or handled research and development. Walt Disney Co. subsidiaries Lucasfilm and Pixar will pay $9 million in cash, and Intuit will shell out $11 million, according to the settlement motion.
