== Problem description ==<br />
With [[Intel_Graphics_Media_Accelerator_900]], After closing and opening the lid, a short flicker of the display appears, and then the picture disappears with the back light remaining on. The image is directed to the external VGA port, and a CRT connected to it will show the image. Using i810switch (as can be seen here: [[Problem_with_video_output_switching#Problems_with_Intel_chipsets]]) the external display will either blank or work again, but the internal LCD remains blank until X restarts.<br />
This is caused by an incorrect resume operation of the Intel device, which results in disabling the internal (B) channel and enabling the external (A) channel.<br />
This behavior was noted on Ubuntu 7.10 and 8.04.<br />
<br />

== Problem description ==<br />
With [[Intel_Graphics_Media_Accelerator_900]], After closing and opening the lid, a short flicker of the display appears, and then the picture disappears with the back light remaining on. The image is directed to the external VGA port, and a CRT connected to it will show the image. Using i810switch (as can be seen here: [[Problem_with_video_output_switching#Problems_with_Intel_chipsets]]) the external display will either blank or work again, but the internal LCD remains blank until X restarts.<br />
This is caused by an incorrect resume operation of the Intel device, which results in disabling the internal (B) channel and enabling the external (A) channel. <br />
<br />
