--- Comment #30 from Ilia Mirkin <[email protected]> --- (In reply to comment #29) > Do you yourself have a geforce 4? I have a NV18 (GeForce4 MX 400) PCI card which shows no such issues at 1920x1200 over VGA with nouveau. Your description of the problem reads like an analog issue, which is why I went for the "do your cables suck" option :) But if the same hw doesn't show the issue with other software, clearly nouveau is at fault. However... who knows why. Certainly bus timings are an option. Perhaps the IGP is configured a little differently than the other stuff. Unfortunately the current code to handle all that for pre-nv50 is basically a sequence of semi-random writes to semi-random places. Take a look at drivers/gpu/drm/nouveau/dispnv04/ to see what I mean. Chances are that in order to get any movement on this issue, you will need to make a mmiotrace of the nvidia driver setting the resolution. See https://wiki.ubuntu.com/X/MMIOTracing for how to do that. With trace in hand, one could then try to match it up with what dispnv04 does. Good times... -- You are receiving this mail because: You are the assignee for the bug.
