[SOLVED] Debian on Lenovo Thinkpad X1 Extreme: X troubles

[bw123]

... the Intel driver should be loaded, but it is not
...

Maybe I'm missing something, but why would you expect intel driver to get loaded, when lspci didn't list any intel graphics device?
https://wiki.debian.org/NvidiaGraphicsD ... tification

...
Why bumblebee if it is the only card?
...

This is an Optimus laptop. As far as I understand, when hybrid graphics is enabled, nvidia piggybacks on intel integrated card. Or somesuch thing.

I want to use Bumblebee (Optimus) so that I get some power saving features (battery life is on the short side with nvidia on all the time).

So I am trying to get it to work. I TURN ON the Hybrid graphics in BIOS. Followed Debian wiki to the best of my knowledge. I must be missing something. So maybe Debian user forums can help.

lspci in hybrid mode *does* detect both cards. Yet X won't start.

Well, like I said I might have missed it/ It's kind of a confusing thread. , where did you show the two cards with the ID instructions on the nvidiadriver wiki page?

I looked up Thinkpad X1 Extreme, and found a page or two at lenovo, didn;t see the word hybrid, or optimus.

p.s. thanks for using testingall those yrs, hope you are reporting a lot of bugs, especially anything that would delay buster going stable on time.

I also looked, did not find much, so I asked here.

I followed the Debian Bumblebee wiki (https://wiki.debian.org/Bumblebee).

Installed everything, made sure -- as far as I can tell -- that no xorg.conf was created by nvidia settings, then rebooted, set the display to Hybrid mode in BIOS, booted ... and no X.
Checked by lspci that I do have both video cards active, looked at X log, googled stuff, asked for help here. In a confusing way, likely.

One of the problems with Nvidia seems to be that the drivers won't build or work on the rt kernel. I have heard that people that needed a lower latency kernel seemed to be happy with the Liquorix kernel, at least for audio processing, and the Nvidia drivers build fine on that kernel.

[adi1334]

@stevepusser - Thanks for reminding me about the Liquorix kernel. Used it a while back, when rt was not (easily) available in Debian. Will have a look again.

lspci lists no intel graphics driver so bumblebee is of no use to you.

perhaps if you change the settings in your bios that may get the intel card to load (if your laptop is indeed an optimus one). my bios setting is switchable graphics on a lenovo y700 (i think).

here's what i see on my optimus laptop

Code: Select all

00:02.0 VGA compatible controller: Intel Corporation HD Graphics 530 (rev 06)
01:00.0 3D controller: NVIDIA Corporation GM107M [GeForce GTX 960M] (rev ff)

My Bios settings that is Hybrid Graphics, which I enabled after installing bumblebee. Consequently, lspci lists 2 graphic cards, in a similar manner as described by yourself. That I have said before. Yet, when that is the case, X will not start. That is my problem and question.

Do you have an xorg.conf file anywhere that specifies using the nvidia driver?

Recent Intel GPUs also require firmware-misc-nonfree be installed from the nonfree section of the repo.

what is your

pertinently do you have the intel one?

i also have this

when it comes to xorg files i have
# locate xorg | grep etc

Code: Select all

I did not have a config file for Intel. OK. I add it to /usr/share/X11/xorg.conf,d (that is the location where X reads the config files, in my case).



AAAAND bAM! That was it, the configuration for intel was missing. Everything works now!

Thank you for your help!


Cheers!!!
