1.20      nia        16: NetBSD 9.0 supports Intel integrated graphics up to Kaby Lake,

1.3       reed       18: 
1.20      nia        19: Anything newer than this will work, but will use `llvmpipe`

1.9       reed       21: 
1.21      nia        22: The support includes connecting external monitors over HDMI,

                     27: compositors, but lightweight window managers can benefit from
                     28: having `picom` running.

                     33: can be used to automatically adjust the CPU frequency depending on
                     34: system load, and potentially prolong battery life. This modifies the
