How reproducible:
Always

Steps to Reproduce:

3.# ddcxinfo (or svgamodes)
4.# sleep 5 (takes 27-28 seconds until prompt comes back)

The svgamodes and ddcxinfo gives correct info tough.

Closing bugs on older, no longer supported, releases. Apologies for any lack of
response.

This is a odd interaction between the real-mode DDC calls and your BIOS. It is
unlikely that it will be fixed at this time.
