So you have 4 identical DP->VGA adapters, each plugged into similar (identical?) monitors, and DP-3 is always the one that fails? Can you attach a dmesg when booting with nouveau.debug=VBIOS=trace,PDISP=trace drm.debug=0xe That should provide a bunch of debug info, perhaps even enough to tell what's going on. Additionally, please attach your vbios (/sys/kernel/debug/dri/0/vbios.rom).</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
