[Bug 1229252] Re: Ubuntu 12.04.3: black screen on PB Easynote and Intel GMA 4500M video adapter

 

I just did a little test. My screen is completely black. Like you turned
it off with a power button on desktop computers. But, when I hit control
+ alt + T, the terminal window opens.

I still can't see a damn thing. When I enter this line in terminal "sudo
setpci -s 00:02.0 F4.B=0", it looks like someone hits the power button.
Full brightness screen appears.

With the command "nomodeset" only resulutions 800x600 (4:3) & 1024x768
(4:3) are available.

But, after entering this line in terminal, I have a visual again on my screen and also the resolutions for my screen:
800x600 (4:3)
1024x768(4:3)
1360x768 (16:9)
1366x768 (16:9)

I could edit rc.local so it looks like this:
#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

sudo setpci -s 00:02.0 F4.B=0
exit 0

This is some what I found on the internet. But what happens when I put
my laptop in a sleepingmode, or screen turns of after no activity? I
heard some stories about people who wrote the screen was black again.
And another question: is editing rc.local a definitive solution or is
there a risk I end up with black screen again?

The information I find, keep believing me, it is a intel graphics
problem, so it doesn't matter what brand laptop you use.
