boot log from 3.14-rc2 with nouveau.debug=PDISP=debug,VBIOS=trace
Using dual monitors, one on DVI and one on Displayport, the displayport output
is blank. The monitor will not come out of sleep mode. xrandr reports both
displays and indicates both displays are active. Have tried disabling/enabling
outputs, and changing orientation.
Tested against kernels:
3.8.13 - works ok on both outputs
3.9.11 - no DP output
3.10.26 - no DP output
3.14-rc2 - no DP output
Tested against following cards:
Quadro 400 (GT216GL) - no DP output
Quadro 600 (GF108FL) - no DP output
Quadro K600 (GK107) - both outputs fine
OS is stock Debian Wheezy 7.2 with updated kernel.
Attached boot log from 3.14-rc2 with 'nouveau.debug=PDISP=debug,VBIOS=trace'
