Hey Folks-

First of all I'd like to thank all those who work on the X and the
drivers as well.  When I bought the laptop last year, I explicitly
bought a centrino, because I wanted the open source intel drivers.

I'm the lucky owner of a 24 inch dell monitor.

Running gentoo, I recompiled the latest ebuilds for X on my Thinkpad
R52 (Intel Corporation Mobile 915GM/GMS/910GML Express Graphics
Controller).  (In case others here are running gentoo I put the
following in /etc/portage/package.keywords:

#new X
x11-drivers/xf86-video-i810 ~x86
x11-base/xorg-server ~x86
x11-proto/randrproto ~x86
x11-libs/libdrm ~x86
x11-libs/libXfont ~x86
media-libs/mesa ~x86
x11-libs/libXdamage ~x86
x11-proto/damageproto ~x86
x11-apps/xrandr ~x86
x11-libs/libXrandr ~x86


I think re-emerged xf86-video-i810 with brought in xf86-video-i810-1.9.92.

My issue is that I now my normal laptop screen (1400x1050) will now
longer work, (with or without the 24inch plugged into the vga port).

xrandr reports the following:

# xrandr

   640x400        85.1
   640x350        85.1
TV disconnected (normal left inverted right)

When I try to use xrandr to use dual screen the following happens:
$ xrandr --output LVDS --auto --left-of VGA
xrandr: screen cannot be larger than 1920x1920 (desired size 3320x1200)

I don't currently have a xorg.conf.

I'm attaching my log file.

Any advice or hints would be wonderful.

thanks much,
