| - | <code> | + | ==== Change CPU governor policy ==== |
| - | setenv baseconfig ahci_imx.hotplug=1 raid=noautodetect telnet root=/dev/mmcblk0p2 video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24 rootwait consoleblank=0 selinux=0 nohdparm splash | + | Per default, //performance// governor is active when Kodi is in use (i.e. no screensaver is active). When Kodi is running idle (with screensaver on), xbian switches to //conservative// governor. To change the governor for active use to //ondemand//, append this line to **/etc/default/xbian-module-init-tools**: |

| - | To enable a terminal on the serial console, copy the file ''/etc/init/tty1.conf'' to ''/etc/init/tty3.conf''. Edit the last line in the new file, replace tty1 with ttymxc0, and 38400 with 115200. It should look like this: | + | |
