hardware: Dell Latitude E6510, nVidia Corporation GT218 [NVS 3100M] + external Dell 21' monitor software: gentoo amd64, xorg-server-1.9.2, xf86-video-nouveau-0.0.16_pre20101010, libdrm-2.4.22 when booting gentoo-sources-2.6.37, upon KMS activation, only external monitor is brought up, the internal laptop display becomes blank an stays that way; xrandr reports both monitors as working/connected! reverting back to gentoo-sources-2.6.36-r7 makes it all work nicely (both internal and external display) both kernels have similar configuration (2.6.37 config was generated using make oldconfig of the 2.6.36-r7 file) and have "nouveau.noaccel=1" on the kernel command line in grub.conf (due to https://bugs.freedesktop.org//show_bug.cgi?id=26980) Reproducible: Always Steps to Reproduce: 1. boot 2.6.37 with external monitor attached to dell latitude e6510/nvidia GT218 and notice the internal display going blank on resolution change (KMS activation) Actual Results: the internal display is blank, but the X server thinks it's active (being the primary monitor it holds all the panels and desktop icons; xrands shows both monitors as being active/connected as well Expected Results: internal display is working
