All your earlier logs appear to indicate it's detected correctly. The issue is that your card is not being detected as dual-link-capable, and the 1600x1200 mode without reduced blanking won't work on it. I have a NV44 and NV42 card, and neither have had trouble getting 1920x1200 going. However an NV34 card can't go beyond 1600x1200 on digital (TMDS). Could you upload a copy of your vbios (/sys/kernel/debug/dri/0/vbios.rom)? Also can you try hacking up your kernel, see nouveau_connector.c:nouveau_connector_mode_valid if (nouveau_duallink && nv_encoder->dcb->duallink_possible) max_clock *= 2; Just get rid of the if statement so that the max_clock *= 2 is always done. Perhaps the nv_device(drm->device)->chipset > 0x46 is wrong in get_tmds_link_bandwidth and it should actually be >= 0x44... although that feels more like a difference between geforce 6- and 7-series. (But then it picks up the igp's as well as the nv4a which is supposed to be just like the nv44...) -- You are receiving this mail because: You are the assignee for the bug.
