That confirms that you have both Xorg-7.7 and Xvesa loaded - in this case tinycore will use the one that was loaded last, presumeably Xorg-7.7, but you can confirm with this command: $ cat /etc/sysconfig/Xserver
As mentioned previously, you need to reboot and only load one of Xfbdev, Xorg-7.7, Xvesa
