Folding Laptop Cover and etc. locked OS bug?

Hi!

I write because if I close my laptop when it is darkness the image. I tried it if I click the screen lock and user change then the same thing happens too.
It isn't 'sleep or hibernate' my laptop. It's full black the screen. The machine is working and it doesn't respond to anything.

What the problem?

My laptop is HP ProBook 6550b.


Thanks for help!

Re: Folding Laptop Cover and etc. locked OS bug?

Hello and welcome.

I don't think this is an Xfce problem, but lets check a few things:

Which distro are you using?
Which kernel?

uname -a

Which video cards/drivers do you have?

lspci -vnn | grep -iA10 VGA

What kernel parameters are you using?

cat /proc/cmdline

And finally, can you post your Xorg.log file?

The active one, Xorg.0.log.

Also, can you post back the results of:

ls /sys/class/backlight

Re: Folding Laptop Cover and etc. locked OS bug?

Please post directly to this thread as opposed to sending things via email, it's the preferred method.

According to your email, you have 2 backlight interfaces:
acpi_video0  & intel_backlight

Also, according to your Xorg.0.log file, you are using the modesetting driver (as opposed to the intel driver). Does this problem exist if you use the intel driver directly?

You might also want to give the "acpi_backlight=vendor" kernel boot parameter a shot, it might get rid of the errant "acpi_video0" interface leaving with 1 - which should make it easier for X to use the correct one.
