Display on the laptop screen at 800x480 is ok. When Xorg starts, the screen syncs again because it sets another resolution. All resolutions work fine, except the native one (1600x1200), even after disabling the laptop screen. > > Upgrading to kernel 2.6.34-1 still gives the same results. Note that the problem also occurs with kms disabled. This screen works fine with a different computer with an intel chipset (G31 express). > Please report this at http://bugs.freedesktop.org/enter_bug.cgi?product=DRI&component=DRM/Intel and attach the information requested at http://intellinuxgraphics.org/how_to_report_bug.html (in particular dmesg from booting with drm.debug=6). Then tell us the bug number so we can track it. Thanks, Julien
