Ben Skeggs <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |ASSIGNED --- Comment #2 from Ben Skeggs <[email protected]> 2009-08-24 20:35:19 PST --- Ok, this looks like a failure to setup dual-link TMDS which the larger monitor would require to run at its native resolution. To solve the immediate problem, load the nouveau kernel module with "modprobe nouveau duallink=0" to reject modes that require more bandwidth than is available on single-link TMDS. You won't be running at your monitor's native mode, but you should have an image. Now, we don't know exactly how to program dual-link as of yet so if you're willing to do some experimentation that'd be *really* good. Also, grabbing traces of the NVIDIA binary driver initialising it would help a lot. See http://nouveau.freedesktop.org/wiki/MmioTrace for details on how to do this. For some random testing that may help, try playing with the uscript_tmds module option. Valid values for most cards are 0x0001 0x0002 and 0x0105. 0x0001 is the default, to try the others use "modprobe nouveau uscript_tmds=0x0105" etc. Thanks! -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ Nouveau mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/nouveau
