DKMS Problem

English Install/Boot/Login

Hey,

I have a DKMS problem. I use the wifi driver rtl8192CU and the following repository on github.

https://github.com/pvaret/rtl8192cu-fixes

I executed the following commands:


cd /home/user/programs/wifi-driver
git clone https://github.com/pvaret/rtl8192cu-fixes.git
sudo dkms add ./rtl8192cu-fixes
sudo dkms install 8192cu/1.11
sudo depmod -a
...

But after a kernel update the module was not rebuild. I have to rebuild manually. After that it works, but it is really painful.

What can I do to resolve this problem?

Thanks in advance
Björn

You have to make sure dkms is running. You can do it in Yast2>System>Services Manager - dkms enable and start. Or you should be able to do it in terminal with

sudo systemctl enable dkms
<password>
sudo systemctl start dkms

Hi Pete,

yes the dkms service was not enabled and started. I have did that and executed dkms install again. After a kernel update the module was not available and I had to build manually again. The problem is not solved.

Is the location of the source code important?

Greetings Björn

It will only autoinstall modules that explicitly request it (man dkms, search for AUTOINSTALL).

Check the dkms.conf file which should be in /usr/src/8192cu-1.11/.
And check

dkms status

.

Why not the rtlwifi driver and the rtl8192cu-firmware from my Repo?
https://download.opensuse.org/repositories/home:/Sauerland:/branches:/home:/Sauerland/openSUSE_Tumbleweed/

That is build automatically if a new kernel is published in the Tumbleweed Repo.
So you can get it automatoically by updating your System if you enabled my Repo.

It is build from Larry Fingers git Repo:

@Sauerland Your repo is my second solution for this problem. I would like to try the build with dkms.

Here my console output:

It looks like module should have been autoinstalled. At this point you really need to troubleshoot it using logs (systemd logs - was service started at all, was it completed or faulted? dkms logs - what happened when dkms run?).

Try a newer version from github (there are more than pvaret’s). Or patch the one you have for kernel-4.15. There is a patch for the newer kernels if you google it (“nvidia kernel.4.15”). But there ought to be an updated attempt if you search 8192cu in github.
I’ve just reread your latest post properly! Forget about this. Sorry.

Why are you trying to run a depricated driver?

“The new rtl8xxxu driver initially introduced in kernel 4.4 works mostly well these days, and you should give it a try before trying this repository.”
