Hi,<br><br>I recently installed Fedora 16 on a Toshiba U500 laptop (as a dual boot with Windows 7). However: <br><br>1) The CPU fan does not run when in Fedora hence making the laptop overheat (though the fan works fine in Windows). <br>
2) Secondly, I am unable to reduce the brightness of the screen using the keyboard function keys.<br><br>Would like to know if anyone has encountered such issues before and if so, how they fixed both (i.e. enabling cpu fan and adjusting screen brightness through keyboard function keys)?<br>
<br>I have tried the following from online forums:<br>1) To install the toshiba omnibook drivers.<br>2) To add the line &quot;echo 10 &gt; /proc/acpi/thermal_zone/THZN/polling_frequency&quot; to &quot;/etc/rc.d/rc.local&quot;, in order to cause the temperature to be read every 10 secs so I don&#39;t have to worry about reading it via an application such as cat
 in a loop.<br><br>Neither of the options work, kindly assist.<br><br>Regards,<br>Michael<br>
