Connecting monitor (CRT Samsung SyncMaster 550b) to DVI-A-0 (VGA-to-DVI adapter) changes nothing (still black screen, even after blind startx). But DRM and X prints correct connector in use.

in my first post (between 59a3759d0fe8d969888c741bb33f4946e4d3750d and c05c0840514599d229e6719d42a2f4e6e0e8ea1e) "comments" = "commits" (sorry) > Kernel driver in use: nouveau
> Kernel modules: nvidiafb
Do you have both nvidiafb and nouveau drivers built? It would worth to try to disable all FB drivers (nvidiafb, rivafb etc.).
I can confirm this. I don't have any fb driver enabled. same here. On my laptop, backlight is on but screen is completely black. So I connected a 17'' Philips external monitor via VGA, [booted with drm.debug=1] now laptop panel displays the correct output and KMS works fine. External monitor displays a cloned screen but actual image is a black screen with oblique dashed lines and cursor. VT switching froze laptop panel output that slowly turns white.

I have this hardware in AGP slot: 01:00.0 VGA compatible controller: nVidia Corporation NV44A [GeForce 6200] (rev a1) (prog-if 00 [VGA controller]) Subsystem: ASUSTeK Computer Inc. Device 81e1 Flags: bus master, 66MHz, medium devsel, latency 64, IRQ 16 Memory at d6000000 (32-bit, non-prefetchable) [size=16M] Memory at c0000000 (32-bit, prefetchable) [size=256M] Memory at d5000000 (32-bit, non-prefetchable) [size=16M] Expansion ROM at d7ee0000 [disabled] [size=128K] Capabilities: [60] Power Management version 2 Capabilities: [44] AGP version 3.0 Kernel driver in use: nouveau Kernel modules: nvidiafb Tried to use in-kernel DRM from http://cgit.freedesktop.org/nouveau/linux-2.6/log/?h=newttm-devel, comments between 59a3759d0fe8d969888c741bb33f4946e4d3750d and c05c0840514599d229e6719d42a2f4e6e0e8ea1e were extracted as patch, and this patch applied to 2.6.30-rc8-git4 (due to unrelated XFS bug in earlier 2.6.30-rc7 kernel) Resulted kernel boots fine, and nouveau DRM works in two-minute testing, but KMS (modeset=1 as module parameter) gives me black screen. No, this time, i verified that fbcon was loaded. Also, DRM thee from http://cgit.freedesktop.org/~jinghua/drm/log/?h=modesetting-gem works fine in KMS mode with my current hardware (I need to correct screen resolution, X seems to be started in doublescan mode, but after this X works ok) Logs will follow ....
