[GUIDE] How to properly install Nvidia Non-Bumblebee drivers on Optimus Laptops [Solved]

[sommenom]

.

In situations where you might have multiple GPUs on a system and X fails to start with:

Code: Select all

(EE) No divices detected.
(EE) Fatal server error
No screens found

Then you need to add your discrete card's BusID to your X configuration. This can happen on systems with an Intel CPU and an integrated GPU or if you have more than one Nvidia card connected. Find your BusID:

Code: Select all

lspci -nn | egrep -i "3d"

Then add BusID to xorg.conf similarly like
4.1 Know the BusID of your dGPU card
and
4.2 Create/Modify xorg.conf

SDDM:
Try copy file Xsetup
from
/usr/share/sddm/scripts/Xsetup
to
/etc/sddm

.

Hi, I follow this tutorial using MX with KDE that uses sddm as Display manager and the setup script is in /use/share/sddm/scripts/Xsetup.
I reboot after step 5 and got a black screen in tty7.
The Xorg log says

Code: Select all

(EE) No divices detected.
(EE) Fatal server error
No screens found

Any suggestions??

I suggest you go back to the help thread you started and not use a guide that is very old post (10 months) by someone who posted 3 times to the forum and never came back.

Several folks (developers and guides) were trying to help you there. Hint: on a fresh install choose "optimus enabled" during Nvidia Driver installer, reboot, add boot code

Hello,

thank you for the guide. I have been stuck with the error message

Code: Select all

nvidia-persistenced failed to initialize. Check syslog for more details.

In /var/log/syslog I saw that the problem was me having no /dev/nvidia* files. That wondered me since my Nvidia card is installed and working with Bumblebee. In the end it was quite simple. Typing

Code: Select all

sudo modprobe nvidia

solved the problem. The /dev/nvidia* files showed up and nvidia-persistenced initialised succsessfully. I am posting this here for anyone having the same problem.

Best regards,
Leonard

I would just like to add on some versions of MX the binary is nvidia-detect-mx for clarity. At least on my version of mx linux

I tried using the MX Tools Nvidia driver on MX 23 AHS (KDE) and it broke the GUI, as it force installed quite an advanced driver.

Found this guide and it worked perfectly. Thanks.

In case this helps someone else, the system is a Clevo laptop with Nvidia 1070M GPU and I7 7700HQ (630 integrated Intel graphics)
