398	  Enable legacy DRI1 drivers. Those drivers expose unsafe and dangerous
399	  APIs to user-space, which can be used to circumvent access
400	  restrictions and other security measures. For backwards compatibility
401	  those drivers are still available, but their use is highly
402	  inadvisable and might harm your system.
403
404	  You are recommended to use the safe modeset-only drivers instead, and
405	  perform 3D emulation in user-space.
406
407	  Unless you have strong reasons to go rogue, say "N".
