| + | If a user generated FAQ is of sufficient interest to other users it may be moved to the global FAQ at http://www.xbian.org/faq/, | ||
| - | This page contains answers and solutions to Frequently Asked Questions and/or common issues. | + | If this happens and you need to update or report an issue, please post you comments along with the corresponding entry to http://forum.xbian.org/thread-2768.html |

| + | ==== Change CPU governor policy ==== | ||
| + | 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**: | ||
| + | //CPUFREQ_GOVERNOR="ondemand"// | ||
| - | + | Note that if you do not set a screensaver, the governor will not fall back to //conservative//, but will instead stick to //performance// or //demand//, depending on your setup. | |

| - | ==== cmdline paramaters ==== | + | |
| - | + | ||
| - | Edit the ''/boot/boot.src.txt'' file and run ''/boot/mks'' afterwards. | + | |
| - | + | ||
| - | ==== HDMI2VGA adapter ==== | + | |
| - | + | ||
| - | If you are using one of these adapters, you may need to change the ''/boot/boot.src.txt'' file from: | + | |
| - | <code> | + | |
| - | 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 | + | |
| - | </code> | + | |
| - | to | + | |
| - | <code> | + | |
| - | setenv baseconfig ahci_imx.hotplug=1 raid=noautodetect telnet root=/dev/mmcblk0p2 video=mxcfb0:dev=hdmi,1280x720M@60,if=RGB565 rootwait consoleblank=0 selinux=0 nohdparm splash | + | |
| - | </code> | + | |
| - | + | ||
| - | If you video mode is incorrect, it can result in a reboot loop. | + | |
| - | + | ||
| - | ==== Enable serial console ==== | + | |
| - | To enable the serial console, add ''console=ttymxc0,115200'' to the command line, after ''setenv baseconfig''. The third line in /boot/boot.src.txt should look something like this: | + | |
| - | <code> | + | |
| - | setenv baseconfig console=ttymxc0,115200 coherent_pool=1M rw 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 dmfc=3 | + | |
| - | </code> | + | |
| - | Run /boot/mks to activate the change. | + | |
| - | + | ||
| - | 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: | + | |
| - | <code> | + | |
| - | exec /sbin/getty -8 115200 ttymxc0 | + | |
| - | </code> | + | |
