 459 <p>Psensor is relying on few libraries or softwares for retrieving the

 461 </div>
 462 <div class="ulist">
 463 <ul>
 464 <li>
 465 <p>motherboard and CPUs sensors: the information is retrieved
 466 from the lm-sensors library, it requires that
 467 sensors-detect has been run and the kernel module
 468 correctly installed. sensors can be used for checking.</p>
 469 </li>
 470 <li>
 471 <p>GPUs: it depends on which driver you are using:</p>
 472 <div class="ulist">
 473 <ul>
 474 <li>
 475 <p>Opensource drivers (nouveau for Nvidia GPUs or
 476 radeon/ati for ATI GPUs) is used and support sensor
 477 monitoring for your GPU, the information is using
 478 lm-sensors, same steps than above.</p>
 479 </li>
 480 <li>
 481 <p>proprietary driver Nvidia: run nvidia-settings to
 482 check that it supports sensors monitoring.</p>
 483 </li>
 484 <li>
 485 <p>proprietary driver Catalyst/fglx: use aticonfig to
 486 check that it supports sensors monitoring. Important
 487 note: it requires that you are using a Psensor
