Hello. Recently I’ve been experiencing problems with the drivers for XUbuntu 20.04, although it has been working properly until today. I have the Linux Kernel 5.4.0-100, a NVIDIA GeForce GT710 card and using the 470 version of the driver.

I’ve already tried purging all the versions, reinstalling them, rebooting…Also tried to include the “pci=realloc” parameter on grub, and tried to use an older driver version without success. This is the bug report log:
nvidia-bug-report.log.gz (84.5 KB)

Thanks in advance!

Edit: Secure Boot does not apply for my computer

Please try loading it manually
sudo modprobe nvidia
and post any errors.

Trying to run sudo modprobe nvidia gives me this error:

modprobe: ERROR: could not insert 'nvidia': Unknown symbol in module, or unknown parameter (see dmesg)

dmesg outputs this:

[ 2144.633834] nvidia: Unknown symbol drm_gem_object_put_unlocked (err -2)

Your system compiler is set to gcc 8.4 but should be 9.3. Please set the correct compiler, then reinstall the driver.

I tried that, with no success sadly.

Tried sudo apt install gcc-9; to ensure it was already installed and it was. Then:

sudo update-alternatives --remove-all gcc;
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-9 10;
sudo update-alternatives --install /usr/bin/cc cc /usr/bin/gcc-9 10;
gcc --version;

Which outputs the gcc version 9.3 correctly.

I also made sure to double and triple check the remaining nvidia files after purging, and two files remained even after purging: libnvidia-compute-470:i386 and libnvidia-compute-390:i386. I removed them manually and reinstalled everything, with no success

Does modprobing it still reports the same error?

7

Yes, it does report the same error as the previous message

8

Please try reinstalling the headers
sudo apt install --reinstall linux-headers-$(uname -r)

9

Done, without success either

I get the feeling dkms doesn’t replace the modules. Please post the output of
dkms status

11

It outputs this:

nvidia, 470.103.01, 5.4.0-100-generic, x86_64: installed
12

Please run
sudo dkms remove nvidia/470.103.01
sudo dkms install nvidia/470.103.01
afterwards, please attach the make log
/var/lib/dkms/nvidia/470.103.01/5.4.0-100-generic/x86_64/log/make.log

13

Here it is:
make.log (1.0 MB)

I only now noticed that the whole drm.ko module is missing in your system, so the nvidia driver is correctly compiled but the module is missing. Please try reinstalling the linux-modules and linux-modules-extra packages and check if lsmod |grep drm shows it.

It worked perfectly! That was the problem. Upon reinstalling the modules for my kernel version and rebooting, now both screens are working properly. lsmod | grep drm shows the modules correctly.

Thanks a lot for your help and time!
