Hi,
After the initial BL installation, I have resolution problems. It seems that xrandr do not recognize my laptop screen (should be 1366x768).
$ xrandr
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1920 x 1080, current 1920 x 1080, maximum 1920 x 1080
default connected 1920x1080+0+0 0mm x 0mm
1920x1080 0.00*
There is no options if I do Preferences->Display->ARandR
Any cue?

It is likely that you have recent hardware, so need a newer kernel and/or graphics.

Indeed, it is likely. But I don't know where to start!
More info:
$ cat /var/log/Xorg.0.log | grep Intel

Maybe search the forum?

I am running the Testing distro (Deuterium). So I guess I am already on the newest kernel.
I was thinking of ideas to deal with X.org stuff maybe?

You can show kernel and graphics information with
uname -r
lspci -knn | grep -iA2 vga
Please use [ code ] tags for posting the terminal output

I am running the Testing distro (Deuterium).
Deuterium is a point release of the *stable* version of BunsenLabs and runs the stock Debian jessie kernel.
That kernel version does not include support for hardware introduced after the stable release because of the potential to introduce new bugs and security vulnerabilities along with a general prohibition on API changes.
To gain such support (and the potential bugs and vulnerabilities that go along with this), you will need to source the kernel from the jessie-backports repositories.
For Intel Broadwell or newer graphics cards, this guide will be needed:

I will bet a cookie that the SKL/KBL in the output stands for "Skylake/Kabylake" (they have similar architectures).

OK, I have the same GPU on my laptop; it's a Skylake 520, so I keep the cookie.
Don't forget the backports firmware-misc-nonfree package for your hardware.

[SOLVED]
This solution referred in post #7 did the job. You rule BL team!
For reference, this problem occurred on a Dell Latitude E7470.

If you hit the edit button on your first post, you can edit both the post and the subject title. Manually add [SOLVED] to the title.
I don't care what you do at home. Would you care to explain?
