Booting with Test Day:2009-09-11 Intel live cd 64bit the inbuilt display always stays black after grub. Only the backlight goes on. After a while I can hear the melody played when it logs in automatically. But the display stays black. I shut it down blindly with power button + return. It shut down regularly.
Booting with an external display attached gives me a picture on the external only. I switched the internal off with xrandr. The backlight went off and I got the menubar and taskbar onto the external monitor.
I have repeated this (external monitor attached) again with drm.debug=1 and produced the attached logs.
A screenshot (Screenshot.png) taken shows the whole screen, including the part I never see.
also tried switching internal on with xrandr --output LVDS1 --auto. the backlight comes back on but no picture.
with nomodeset it works fine.
dpms: screensaver does not kick in but power management does and it recovers correctly.
enabling desktop effects fails with something like hardware not supported.
VT terminal switching works.
suspend resume works with external.
I have also tried this with current ubuntu karmic and filed a bug there:
00:02.0 VGA compatible controller : Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller [8086:2a42] (rev 07) (prog-if 00 [VGA controller])
Subsystem: Acer Incorporated [ALI] Device [1025:0253]
/etc/X11/xorg.conf does not exist.
