... I think. I'm seeing this error from an apt-get dist-upgrade, it appears every time.

Any ideas? Should I purge the installed nvidia driver and re-apply the update?

TIA

Forgot to mention - ubuntu 16.04, GTX750Ti, 8GB.

All is well with the desktop otherwise.

pablosquared; Well;

As a 1st look, appears there is a driver conflict between 361 and 367.
Let's look at what is installed, then see what needs to be done to get only one - there can be only 1 .


dpkg -l | grep -i nvidia
dkms status
lsmod | grep nvidia


a clean system


is a happy system

pablosquared; Hello;

Sorry for the delay ... life has a way of intruding.

Anyway, as you can see we do have driver conflicts ( that ii as the first field in the dpkg output ).
Let's clean things up, as there can be but one control for one particular graphic set - I do note that this is in all likely hood hybrid graphics .


sudo apt purge nvidia*
sudo rm /etc/X11/Xorg.conf


And now we install the driver.


sudo apt update
sudo ubuntu-drivers autoinstall
sudo apt upgrade

where we allow the system to install what it thinks best - from what it has to choose from.
As you have installed version 367, I bet that :
https://launchpad.net/~graphics-drivers/+archive/ubuntu/ppa
is the source, as that one is the preferred means to obtain the 367 version driver.
For now, we accept what the system thinks .. and IF there is a problem then we re-address it .

Reboot the system for the change in driver(s) to take effect:


sudo shutdown -r now

Advise when rebooted what the situation is.



ain't nothing but a thing

[pablosquared]

Thanks so much, Bashing-om (https://ubuntuforums.org/member.php?u=1111508), appreciate your help. Life does have a way of knocking plans for 6..

I purged the nvidia driver and rebooted back (into low graphics mode). My system doesn't have an xorg.conf.

I re-installed the 367 driver per your instruction, screens etc. returned to normal arrangements. Still getting the same error when updating, however. I don't have any non-std repositories for nvidia drivers installed - I've spent way too long trying to fix fix / upgrade nvidia drivers over many years / systems, content for a quieter life now.:)

From looking at synaptic:



nvidia-opencl-icd-361
Transitional package for nvidia-opencl-icd-367


This issue isn't presenting a problem, but it is an annoyance. Any further suggestions?

TIA

You also showed bbswitch.

bbswitch is a kernel module which automatically detects the required ACPI
calls for two kinds of Optimus laptops. It has been verified to work with
"real" Optimus and "legacy" Optimus laptops (at least, that is what the
author Lekensteyn calls those).


Is your system Optimus?

[pablosquared]

Hi oldfred. No, my system is a custom desktop, not a laptop, Optimus or otherwise.

[pablosquared]

And that was the problem - I un-installed bbswitch-dkms, rebooted, updated (which reinstalled the nvidia 367 driver)- no errors.

I vaguely remember installing bbswitch a while ago for what seemed a good reason - guess I got that wrong.

Thanks so much for your help, both - much appreciated.

pablosquared; Outstanding !

You do good work !

Glad it all worked out .



just keep on keep'n on
