Getting started with WIFI and NVIDIA

General system Newbie
1

Hello, this is my first Post. So today i downloaded EndeavorOS for the 6. time while trying to either install my wifi-card driver or my nvidia drivers. So i wanted to ask the “easiest” way to install them.

Currently im having two problems:

My Specs:

  • i5-85250U

  • Mx150

  • RealtelkRTC8821CE

  • 8 GB RAM

  • KDE Plasma

Probably because the wifi card is realtek not Intel… Normally the driver is implemented in the Linux Kernel. If it isn’t it can create problems.

I suggest you check out the driver on AUR

https://aur.archlinux.org/packages?O=0&SeB=nd&K=Rtl8821CE&outdated=&SB=p&SO=d&PP=50&submit=Go

To install first update your system:

sudo pacman -Syu

Then install the driver

yay -S rtl8821ce-dkms-git

Of course check first if it is the correct driver and use the AUR at your own risk and follow good practice.

This is pretty easy. First post better system information. Go on top of forum >help>eos log tool and post system infos here about your graphics card and installed drivers so we know where you are at. Right now it is unclear why you downloaded eos 6 times…

This article describes how to install the Nvidia driver,

https://discovery.endeavouros.com/nvidia/nvidia-installer/2021/03/

Test installation:

nvidia-installer-dkms -t

When there are no errors reported, then run:

sudo nvidia-installer-dkms

This will install Nvidia proprietary drivers and performs some configuration inside /etc/X11/xorg.conf.d/

Then run:

sudo systemctl reboot

All commands from article. you can also boot the recent eos iso in Nvidia mode but I prefer to install it myself.

Welcome to the forum! :smile:

For the record, can you show the output of

Hardware information:

https://clbin.com/Mbf1S

is the dkms not for another linux kernel?

And i think i fortgot to mention i am dualbooting with windows 11

8

Which other kernel? From the eos discover article link I posted above:

The package is available from EndeavourOS Repository to install it:

sudo pacman -S nvidia-installer-dkms

We ship the dkms version by default so the drivers can be kept up-to-date, regardless of the kernel version you’re using. Using the dkms version also means, you need to install the kernel header packages that match to your installed kernel(s).If you are using our AKM tool, the headers will be installed by default.

// example for linux-lts: sudo pacman -S linux-lts-headers

From what I can see of your hardware output, newest Nvidia driver was installed. If you want to run another kernel like lts I suggest you simply use the akm tool.

Now to switch between your Intel and Nvidia card that’s another story.

Here is the short story:

You could use Optimus manager:

https://discovery.endeavouros.com/nvidia/optimus-manager-for-nvidia/2021/03/

From your post it is unclear what problem you have with Nvidia. The other post you were referring to had screen freezes because he didn’t install correctly his RAM hardware… Are you experiencing screen freezes? If yes I suggest to save the journal log right after it happens and post the link here. You can use the eos log tool installed by default or accessible via welcome app :grin:

I installed Optimus-Manager and will try it out, thanks
Ill post the journal after the freeze asap

I downloaded the driver

yay -S rtl8821ce-dkms-git

there is still this problem
no internet

after rebooting my wificard completely disappears.

what sometimes works is that i boot into windows and then it works.

11

You can always remove the driver if it doesn’t work. Another test worth trying is to install the lts kernel (use the akm app) and check if that may work better. Sometimes it fixes some of these driver issues. Then reboot to that kernel that should appear in grub.

https://discovery.endeavouros.com/endeavouros-tools/akm/2021/08/

Both Nvidia and realtek have been a pain on Linux as long as I can remember having used Linux…

12

Do i have to install the lts-Header Aswell?

And do i always have to boot from LTS later on

13

If you want to boot into lts kernel yes. You can choose lts or current kernel at boot. Lts means long term support.

14

So I installed AKM
image
The Problem is, it does not show up in GRUB

15

Ok that’s pretty easy, has to do with the August grub debacle…

Here is the info of what to do, was just implemented in the new iso.

16

I Booted into LTS and had the same issue with wifi :frowning:
I discoverd something new:
this is what i do and what happens:

  1. Sleep

  2. Wake up
    → Wifi doesnt find any network

  3. reboot (REBOOT | not Shutdown)
    → Wifi card doesnt show up

Btw. thank you really much for the help with optmius etc… Didnt expect that fast and good help

17

Ok, I think your best bet if you can’t find a reasonable driver for the wifi is to get an Intel wifi card if your laptop allows to swap it and you feel comfortable doing it. There maybe other troubleshooting possibilities with sleep and configuration files but that is beyond my current knowledge…

18

So i was a bit digging and found this occuring
wpa_supplicant
