<snip> You will need to install the xserver-xomap with RandR support, as well as flash the kernel with RrandR support before this package will do anything. Since the updated components can't be a dependecy, you are required to do it yourself. This one-click-install will provide you with an updateable xserver-xomap if you are not already using it. After the package installation is complete, update the xserver-xomap by either the application manager or apt-get. Then flash your N810 with this kernel and reboot to complete the installation If you do not know how to flash the kernel or update the xserver-xomap, you are advised not to install this package at all, as you may brick your device while experimenting. <snip>
