| As the display resolution is coded into the kernel source, just bolting in the new panel and hoping for the best will not render a satisfying result. Consequently, the kernel has to be recompiled to the new hardware setup. The following guide assumes you installed Ubuntu according to their [[https://wiki.ubuntu.com/ARM/TEGRA/AC100#Installing_Ubuntu_11.10_on_the_AC100|wiki article]]. If you use a custom kernel or any other solution, refer to the [[kerneldev]] page to get an idea about compiling for the AC100. In general, you just need to follow the instructions on how to [[https://help.ubuntu.com/community/Kernel/Compile|compile a custom Ubuntu kernel]] - with just a little deviation. The following guide is just a recommendation and certainly not the only way to do it. | As the display resolution is coded into the kernel source, just bolting in the new panel and hoping for the best will not render a satisfying result.

| The easiest and thus recommended way is to compile natively on your AC100 and use apt-source to get the source. To do so, you need the following: | The easiest and thus recommended way is to compile natively on your AC100 and use apt-source to get the source. To do so, you need the following: |
