Sorry, I should have been clearer. Try this command:

pastebinit  /usr/share/X11/xorg.conf.d/20-intel.conf

...and post back the link that is generated.

In addition to the other 2.

jane@jane:~$ pastebinit  /usr/share/X11/xorg.conf.d/20-intel.conf
The program 'pastebinit' can be found in the following packages:
 * pastebinit

Try: sudo apt-get install <selected package>


jane@jane:~$ pastebinit /var/log/dmesg

Perhaps I misunderstood something...log files and link are to get in a different way?
By the way, for some time Ubuntu was installed, such a problem did not occure.

You need to install pastebinit. Do it like this:

sudo apt-get install pastebinit

...enter your password when prompted. When done, run the previous 3 pastebinit commands.

Now the pastebinit-installation was successful, whatever the reason might be. Same commands before did not work.
Here are the links:

Thanks a lot for your help!

Can you try the acpi_backlight=vendor kernel parameter? Here is how (from a terminal):

1. Edit the configuration file:

sudo -i leafpad /etc/default/grub

...enter your password when prompted.

2. Change the line that reads:

GRUB_CMDLINE_LINUX=""

...so that it says:

GRUB_CMDLINE_LINUX="acpi_backlight=vendor"

3. Save the file.

4. Commit the change:

sudo update-grub

5. Reboot your computer and try again.

*If it still doesn't work, can you post back again:

pastebinit /var/log/dmesg

...and

pastebinit /var/log/Xorg.0.log

Just in case you need this, too:

With the acpi_backlight=vendor parameter active, what does the following command now return:

for i in /sys/class/backlight/*; do echo $i; cat $i/brightness; cat $i/actual_brightness; cat $i/max_brightness; done

Can you also install xbacklight:

sudo apt-get install xbacklight

...and try adjusting the backlight via:

xbacklight -dec 10
xbacklight -inc 10

...and see if that changes the backlight?

Hello,

Unfortunately that did not work out, too.
