Package: linux-2.6
Version: 2.6.32-15
Severity: normal
Tags: upstream

When booting, after the grub menu, the external screen starts being unable to 
sync as soon as KMS sets the mode for the screen (1600x1200, which is the 
native resolution). 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).
