+ | 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, | ||
+ | ==== Requirements ==== | ||
+ | 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: | ||
+ | * your AC100, running Ubuntu and connected to the internet | ||
+ | * external storage, USB or SD, 2GB ext2 or higher (if you don't know how to format your storage, use the Disk Utility provided by your Ubuntu distribution) | ||
+ | * the package " | ||
+ | * enough power in the battery or power connection as compiling will take up to 60 minutes | ||
+ | ==== Getting the Source ==== | ||
+ | Now you need to get the source code of the kernel you are currently using, preferably onto the external storage you prepared earlier. | ||
+ | - insert and mount external storage | ||
+ | - open a terminal and change your path to the storage < | ||
+ | - get the source by typing < | ||
+ | apt-get source linux-image-$(uname -r)</ | ||
+ | - there should be a new folder with the source code inside, change into that folder | ||
+ | ==== Changing the Source ==== | ||
+ | Now you need to change the file / | ||
+ | - open the file in an editor < | ||
+ | - search for this bit: < | ||
+ | | ||
+ | | ||
+ | .end = 0x1fd95000 + 0x26B000 - 1, // 2.4 MB @ 509 MB | ||
+ | | ||
+ | | ||
+ | </ | ||
+ | - then in this: < | ||
+ | { | ||
+ | .pclk = 42430000, | ||
+ | | ||
+ | | ||
+ | | ||
+ | | ||
+ | | ||
+ | | ||
+ | .h_active = 1024, | ||
+ | .v_active = 600, | ||
+ | | ||
+ | | ||
+ | | ||
+ | </ | ||
+ | .v_active = 720, | ||
+ | </ | ||
+ | - finally, look for < | ||
+ | | ||
+ | .xres = 1024, | ||
+ | .yres = 600, | ||
+ | | ||
+ | | ||
+ | .yres = 720,</ | ||
+ | - save your changes and quit the editor | ||
+ | ==== Compiling & Installing ==== | ||
+ | Now that the source code is changed according to your hardware, you can compile your custom kernel by entering < | ||
+ | After rebooting, you should be able to fully enjoy your new LCD panel. |
