This is because the new xserver-xorg-video-intel enables KMS by default
(by including /etc/modprobe.d/i915-kms.conf), and you are probably using
the vesafb driver for the console. Do a "dmesg|grep -E 'fb|drm'" to
The vesafb usage may be unintentionally like it was for me, by having a
vga=xxx option on the kernel command line. If so, then remove it from
/boot/grub/menu.lst (or grub.cfg or /etc/lilo.conf or whatever), rerun
update-grub and be set.
You'll notice that you get the standard 80x24 console until X is started
and first then a nice native resolution console. If you want the native
resolution console from the start, then add something like
"video=i915:modeset=1" to the kernel command line and rerun "update-grub"
and "update-initramfs -u -k `uname -r`".
