Snapshot 20210527 - Usr merge and compile kernel modules

**malcolmlewis** · 01-Jun-2021, 17:26

Hi
Likely issues with compiling modules... See https://lists.opensuse.org/archives/...QJ27IEVA5WUTW/

I had the issue compiling the nvidia module... the following fixes;

Code:

cd /usr/lib/modules/5.12.4-2-default/

find . -type l -ls

build -> ../../../usr/src/linux-5.12.4-2-obj/x86_64/default
source -> ../../../usr/src/linux-5.12.4-2

rm build source

ln -s ../../../../usr/src/linux-5.12.4-2-obj/x86_64/default build
ln -s ../../../../usr/src/linux-5.12.4-2 source

Hi Malcolm

I am running a multi boot with Win 10.

So I decided to re-install TW with the 270521 snapshot. All went well until I used;

sudo zypper addrepo --refreshhttps://download.nvidia.com/opensuse/tumbleweed NVIDIA
sudo zypper refresh
sudo zypper in x11-video-nvidiaG05

to install the nvidia prop drivers.

On reboot the screen log in for Gnome became very big and trying to log in became imposible.

Should I use the commands you gave and if so please could you kindly verify if
for example;

build -> ../../../usr/src/linux-5.12.4-2-obj/x86_64/default
source -> ../../../usr/src/linux-5.12.4-2

is all on one line? Because by the looks of it I may have to re-install.

Thanks in advance and also for your help in allowing me to log back in to the forums.

Regards

Steve

Hi
In your example, that is incorrect it only goes up three levels, you should see the items in red in the output of command 2;

Code:

command 1: cd /usr/lib/modules/5.12.4-2-default/

command 2: find . -type l -ls

command 3: rm build source

command 4: ln -s ../../../../usr/src/linux-5.12.4-2-obj/x86_64/default build

command 5: ln -s ../../../../usr/src/linux-5.12.4-2 source

Those are not the commands. Those two lines are the output from the earlier commands.

These are the commands that you need:

Code:

cd /usr/lib/modules/5.12.4-2-default/
rm build source
ln -s ../../../../usr/src/linux-5.12.4-2-obj/x86_64/default build
ln -s ../../../../usr/src/linux-5.12.4-2 source

That's 4 commands, and you need to run those as root.

It is actually

Code:

ln -s ../../../src/linux-5.12.4-2-obj/x86_64/default build
ln -s ../../../src/linux-5.12.4-2 source

There is no need to climb to the top; both /usr/lib and /usr/src are under /usr now. This is link that will be created by kernel packages automatically after UsrMerge.

But your version works of course.

Pretty intimidating:

Code:

The following product is going to be upgraded: 
openSUSE Tumbleweed 
  20210524-0 -> 20210527-0 

The following 5 packages require a system reboot: 
  dbus-1 glibc kernel-default-5.12.4-2.1 libopenssl1_1 systemd 

3254 packages to upgrade, 9 new. 
Overall download size: 0 B. Already cached: 3.29 GiB. After the operation, additional 403.9 MiB will be used. 

    Note: System reboot required.

Some 20 minutes smooth upgrade.

Thanks very much for the posts.

I did a fresh install yesterday based on the latest ISO and hit this problem.

**marel** · 02-Jun-2021, 03:15

Update and reboot were also smooth here.

On thing I noticed is that my local installed java was not present anymore.
I have a script starting josm using that was using local installed java because of performance issues and that was outputting:

/usr/java/jdk1.8.0_261-amd64/bin/java: No such file or directory

So with the usr merge that has gone.
Solved the problem by installing the josm package, will keep that until I run in performance problems again, maybe the reason why I did switch in the past to Oracle java is gone.

I, on the other hand, had no problem with my Nvidia Geforce 610
