Created attachment 25287 [details] LMDS display with inteldrmfb running 00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller [8086:2a02] (rev 03) (prog-if 00 [VGA controller]) Subsystem: Fujitsu Siemens Computers Device [1734:110e] X server 1.6.1, libdrm 2.4.9 (from PLD Linux i686) running on Fujitsu Siemens Esprimo Mobile V5505. After activating KMS (and only then) I've encountered problem with screen resolution/timing: - 2.6.3 Intel driver: initial (first-run) screen is smaller (like http://launchpadlibrarian.net/12354400/screen.png), restarting X fixes the problem, as well as setting https://wiki.ubuntu.com/X/Quirks#Ignore%20TV%20Output%20Quirk - 2.7.0 Intel driver: screen photo attached, none of the xorg.conf settings help to work this out.
xrandr with KMS: Screen 0: minimum 320 x 200, current 1280 x 800, maximum 8192 x 8192 VGA1 disconnected (normal left inverted right x axis y axis) LVDS1 connected 1280x800+0+0 (normal left inverted right x axis y axis) 331mm x 207mm 1280x800 60.0*+ TV1 disconnected (normal left inverted right x axis y axis) xrandr without KMS: Screen 0: minimum 320 x 200, current 1280 x 800, maximum 4096 x 4096 VGA disconnected (normal left inverted right x axis y axis) LVDS connected 1280x800+0+0 (normal left inverted right x axis y axis) 331mm x 207mm 1280x800 60.0*+ 1024x768 85.0 75.0 70.1 60.0 832x624 74.6 800x600 85.1 72.2 75.0 60.3 56.2 640x480 85.0 72.8 75.0 59.9 720x400 85.0 640x400 85.1 640x350 85.1 TV disconnected (normal left inverted right x axis y axis)

Created attachment 25295 [details] X server log with KMS active Note: 1. (II) intel(0): Output TV1 connected when it's NOT (I've got nothing but laptop LCD attached). It happens sometimes, otherwise I get: (II) intel(0): Using exact sizes for initial modes instead of "sloppy heuristic". 2. (II) intel(0): Output VGA1 using monitor section LVDS (II) intel(0): Output LVDS1 using monitor section LVDS VGA is not connected either and default (empty) xorg.conf produces: (II) intel(0): Output VGA1 using monitor section Monitor0 (II) intel(0): Output LVDS1 has no monitor section but it's the same like without KMS (when it works fine). 3. (==) intel(0): VideoRam: 4194303 KB without KMS it's more real: (==) intel(0): VideoRam: 262144 KB 4. without KMS there's more entries in Xorg.*.log, like (II) intel(0): found backlight control method /sys/class/backlight/acpi_video0 (II) intel(0): detected 512 kB GTT. (II) intel(0): detected 7676 kB stolen memory.

I'm not using KMS anyway (fbcon under inteldrmfb it's almost 2 times slower than uvesafb, there's also slideshow when using xterm+mc viewer), but if more info is required I can switch.
I don't see any resolution symptom. My understanding is your main pain is "broken screen with tiling" with 2.7.0 driver. That's a known issue and you need an additional kernel patch. *** This bug has been marked as a duplicate of bug 21246 ***
