i am writing an app that implements some openGL functionality. i want to be able to use color indexing in my opengl code, but i can't currently do that because because my visual is "truecolor". from what i have read, i need to be in pseudocolor or directcolor mode in order to use color indexing. can anyone help me figure out how to configure my x server so that i am in one of those modes? ideally, i would be able to configure it for one user so that when i log on with them the visual is in pseudocolor and truecolor for all others. any ideas?
