Ah, the power of flags. We had the same issue with user requesting a mode change or fbcon asking for a different mode. We handled it with the flag FBINFO_MISC_USEREVENT. Since you are using KMS as the backend for fbcon you will have to deal also with the ability to change the resolution with tools like stty. I can easily see how to do this plus give you more memory like you want :-) For the oops are you talking about printing oops to the screen while X is running ? Otherwise if you experience a oops and go back to console mode you should be able to view it. The console text buffer is independent of the graphics card memory system. ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
