Video output issues since video card swap

I swapped my video card from a Radeon 2400-pro to an R5 240. Since then, I get no signal after the boot screen finishes. One of my monitors just shows no signal, while a few other monitors say it’s an unsupported resolution. The fallback driver does work, but it’s stuck at 1024x768, not a great option since all my monitors are higher than that. I’m using a DVI to VGA adapter, I checked continuity for all the pins and it seems perfect. I would like help if anyone has ideas how to make this card fully functional in Haiku. I’m on beta 2 and recently ran updates.

Suggestions:

  1. Use the nightly branch. First, test with a new live DVD from the nightly branch for your platform.
  2. Create a bug report (component/driver/radeonhd). Attach your syslog. Track with Haiku dev team.
  3. Try to talk to devs in Haiku IRC.
