Not strictly. You can also exercise the head with just the framebuffer console since every DRM-driven device can also be made to operate as a framebuffer device. I've successfully done testing that way. You're probably going to need more info for how to actually control the video timings. Before KMS came along you did everything in xorg.conf. With KMS in the picture and the ability to use this stuff outside of xorg, there's actually a whole 'nother way to set the video mode, via that "video=" kernel parameter syntax. > > > > > > But right now since the project I'm on absolutely needs this ability, > > then we're probably just going to end up maintaining the (pretty > > simple) > > patch out-of-tree. > > So I don't have to go searching through the archives, can you give me > an approximate date you posted this patch so I can try it out? Look for a patch series posted by me to this list back on March 17th. There are 3 patches in 4 posts. The first post explains everything so you'll definitely want to look at that as well. The patch series implements the ability to disable scaling - the first solution I mentioned earlier. IIRC, two of the three patches have been merged, the controversial one that actually enables fixed mode timing however has not been merged. I also have this stuff rebased against a 2.6.38.5 vanilla kernel, if interested. -Mike -- Mike Isely isely @ isely (dot) net PGP: 03 54 43 4D 75 E5 CC 92 71 16 01 E2 B5 F5 C1 E8 _______________________________________________ Intel-gfx mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/intel-gfx
