Hello, I used opengl for one course a year ago(I do not remember which implementation I downloaded and where it came from). Anyway everything was fine at that time except it failed to render big pictures(probably because my computer does not have good graphic card). Now, I need to use xming which said it requires Mesa Libraries-a software implementation of OpenGL. But after I installed Mesa , xming does not work---display failure. Worse, I find that the programs I wrote before have uglier output than before. Is it because Mesa supercedes the previous implementation in my computer? How can I force my opengl program to use the previous implementation instead of Mesa ? Besides, do you have any ideas why xming fails? Thank you.
