Can't adjust brightness.

[u3000]

There no brightness (as well as no Wi-Fi checkbox) in Battery and Brightness section of Status and Notification widget on the panel and it can't be adjusted with Fn+F11/F12. Had no problems with it in Ubuntu or Manjaro.

You need to tell us which version of Debian you are using (and which desktop) and also provide information about your graphics hardware.

[u3000]

9.9.0 from here: https://www.debian.org/distrib/

[arochester]

(and which desktop)

Gnome? KDE? Xfce? LXQt? Other?

[u3000]

KDE.

[Wheelerof4te]

Ok, install inxi. Then, as normal user type this magic incarnation into terminal:

Code: Select all

inxi -F

Paste the result here.
IIRC, brightness in KDE can be changed in the power settings and from the panel widget. Just go through the settings and you will find it.

[Head_on_a_Stick]

No need for inxi:

https://wiki.debian.org/HowToIdentifyADevice/PCI

The [VID:PID] codes are useful for searching.

[stevepusser]

Isn't inxi easier for a beginner to use and provide us with the critical data, though? I really prefer it to picking through 10,000 irrelevant lines of lspci output, especially when the problem is probably something like Skylake or above Intel hardware.

There is in Debian repositories, What "repos" did you try ?

https://packages.debian.org/jessie/misc/inxi

[arzgi]

inxi also in stretch:

Code: Select all

 :~$aptitude search inxi
i   inxi                            - full featured system information script 

[GarryRicketson]

It is in Buster as well, I did not see anywhere that the OP mentions what version of Debian they are using, but maybe I just did not read it all carefully:
https://packages.debian.org/buster/inxi

[u3000]

I'll see right now. But why Debian so semi-finished (like frozen dumplings)?

[GarryRicketson]

You need to tell us which version of Debian you are using (and which desktop) and also provide information about your graphics hardware.

And please put the info in code boxes, so it is clear and easy to read. It probably does not matter if you use

Code: Select all

$ lsb_release -a

For version info, and

Code: Select all

$ lspci

or if you use 'inixi', the important thing is to include the info and details.

[GarryRicketson]

I'll see right now. But why Debian so semi-finished (like frozen dumplings)?

If Debian does not seem complete enough, maybe you should be using something else.
I generally start with just the Debian base, no DE , nothing except the essential utilities, then add the few additional packages I want. But, guess that would be another topic, and so would complaints about Debian not being complete or finished enough.
The so called "finished install" images are so bloated and loaded with totally useless packages, that many of us do not really want any way, Debian is/was intended for those that prefer to start with a good reliable base, and build a "finshed" system as they see fit, but thanks to people like the OP , that is changing, and now we have install images that are so bloated it takes hours to download them, and then many more hours removing all the bloat.

[u3000]

Sorry for code boxes, I posted lspci output in the previous post.
Not all of them bloated as you said, in fact installation process took much much more time with Debian than with some Ubuntu/Ubuntu-based distro.
I'm trying Debian because none of last (sill supported) versions of Ubuntu's worked without problems on my new laptop (there one or the other unsolvable problem).
I have 9.9.0 stretch.
Here is my repos.

[Head_on_a_Stick]

Here is my repos.

Please post the content of /etc/apt/sources.list (and any files under /etc/apt/sources.list.d/) directly rather than posting a picture of some lame graphical tool that may or may not work as intended.

This command will also list your (active) sources:

Code: Select all

apt policy

Anyway, from the posted lspci output it looks like your hardware is too new for the Debian stable release.

To get a better output use

Code: Select all

# update-pciids
lspci -knn

Then search for the [VID:PID] codes for all of the devices that do not list a kernel driver.

Installing a newer kernel version from the backports repository is probably a good place to start:

http://forums.debian.net/viewtopic.php?f=16&t=139003

But you may be better off waiting until Debian 10 is released in a few months.

I can recommend Arch Linux until then, it's surprisingly reliable for such a cutting-edge distribution and *much* simpler than Debian to manage.

Parabola GNU/Linux-libre is another good alternative if non-free software is a problem for you.

[u3000]

Alright, then I'm done with Debian (for a while may be). Thanks a lot for support.

[stevepusser]

Or if you want to stay in the Debian sort of family, MX Linux is based on Stretch, but is updated to support newer hardware.

Inxi is in the repos, but you don't have the main Debian repo enabled or even in your list, according to the screenshot--just a security update repo. This will happen if you don't have a Net connection during the install.

Inxi does give more easily recognizable output than lspci, unless you have the entire PCI ID database memorized.

lspci:

Code: Select all

00:02.0 VGA compatible controller: Intel Corporation Device 3e9b
01:00.0 3D controller: NVIDIA Corporation Device 1c8c (rev ff)

inxi -G:

Code: Select all

Graphics:  Device-1: Intel driver: i915 v: kernel 
           Device-2: NVIDIA driver: N/A 
           Display: x11 server: X.Org 1.19.2 driver: intel resolution: 1920x1080~60Hz 
           OpenGL: renderer: Mesa DRI Intel UHD Graphics 630 (Coffeelake 3x8 GT2) 
           v: 4.5 Mesa 18.3.2 

Even in Buster or Sid, more recent Intel hardware also need firmware-misc-nonfree installed.
