I went back and checked, and it was specifically this commit (r26762) that started causing a few issues for me: http://lists.berlios.de/pipermail/haiku-commits/2008-August/015932.html I'm guessing it was specifically this part: - if (timing.pixel_clock <= 0 || timing.sync != 3) + if (timing.pixel_clock <= 0/* || timing.sync != 3*/) I'm wondering if reverting that line might fix it? - Urias
