[LAPTOP] Nvidia Driver Visual Glitches with Nvdia 1060 max-q

[wrender]

I used software sources to download the Additional Drivers tool to download and install the Proprietery Nvidia driver and intel microcode update. However since I did that I have noticed that I get strange visual artifacts around my mouse and on screen while typing.

The version it installed is 384.90 and the one on the site is 384.98 I remember they used to have an option for stable or latest. This time there was only one option to choose.

I am goiun g to guess that you only see one option is because your very recent card is not supported by the other older driver versions available in Ubuntu's repos. I just got a gtx 1050, which is somewhat new-ish, and only see one Nvidia choice of the 384 driver (in Kubuntu 17.10). There is an Ubuntu ppa for updated Nvidia drivers here
https://launchpad.net/~graphics-driv..._filter=xenial
where you can get the 387 driver, which might work a little better on your newer card. I have three choices for the non-free drivers with this added: 381, 384, and 387

381 and 384 we very buggy for me. I only have a GTX 780 but 387 is the only driver that works well here.

The next time you boot up and are at the login screen use Ctrl+Alt+F2 to get a terminal, then issue
sudo systemctl restart sddm

and then log in.

I think sddm 0.16.0-3 fixes the problem

It's funny as I always thought that the additional drivers tool just used a nvidia ppa to get the latest...

[wrender]

I purged all old nvidia stuff and then added the ppa and installed the latest binary driver which is 387.34 (although it did say open source in brackets at the end which I find weird). It didn't help.

I did the sudo systemctl restart sddm. Which seemed to temporarily fix it for that session.

However, I actually found that after boot up I would log out then log in and it seemed to do the temporary fix for the session as well. So not sure what is affected by that...

[oshunluvr]

Umm, not open source.

Maybe you saw "OpenCL ICD?"

"OpenCL" means "Open Computing Language" - from wiki: "OpenCL (Open Computing Language) is a multivendor open standard for general-purpose parallel programming of heterogeneous systems that include CPUs, GPUs and other processors" This is not the same as "Open Source" which means the source code is available to be viewed or edited and re-complied by anyone.

"ICD" means "Installable Client Driver" - which is both obvious and redundant.

To your other comments, all PPAs available by default are serviced by Canonical. Many, many, specific packages are available in newer or different versions from non-Canonical PPA sources - but you have to enable those types of PPAs yourself. The general rule-of-thumb is stick with "factory" until you can't - and this is one of those cases. Canonical's adaptation of external drivers like nVidia's is not done in any sort of timely fashion.

Your last comment re. logging in vs. booting up or restarting sddm I didn't understand.

I just double checked and it says
"Using NVIDIA binary driver - version 387.34 from nvidia-387(open source)

If I turn on my laptop and log in the graphical glitches are present. If I log out and log back it the glitches are gone for that session.

I just double checked and it says
"Using NVIDIA binary driver - version 387.34 from nvidia-387(open source)

Wow, interesting. I've never seen that - where are you seeing that? AFAIK, the only open source driver is Nouveau.

[wrender]

Yeh it is confusing that it mentions open source...

But I have the full Nvidia panel and I have been using some heavy Opengl 4.6 Apps with 3d simulations going and they recognize the card and driver.

[wrender]

Any thoughts if it is kde issue or nvidia driver issue connected to the artifacts for the first login?

[vinnywright]

their is a nvidia-390 driver out now as well

[vinnywright]

forgot to add that the nvidia-390 driver is coming from this PPA added to /etc/apt/sources.list

#graphics drivers (nvidia)
deb http://ppa.launchpad.net/graphics-drivers/ppa/ubuntu/ xenial main

I'm using the 390.12 driver which didn't change anything.

I mean it isn't terrible as when I boot up and log in and out and in the artifacts go away for that session. But it would be great to find the culprit so I don't have to do the dance.

[GreyGeek]

I'm running the nvidia-378.13 driver for my GT650M chip and I have to do the dance as well.
I use Ctl+Alt+F2 at the login screen, log into the F2 terminal, run "sudo systemctl restart sddm" to get the login screen back, and then enter my password again (third time). I tried the 384 &387 nvidia drivers but they didn't help.

This Acer V3-771G laptop has two GPU's. The primary is an Intel 4000HD and the secondary is the NVidia GT 650M, which CANNOT be set as the primary in the BIOS. Several years ago I tried using Optimus and Bumblebee and got marginal to poor results. When I installed the 378.13 driver it made my GT650M the PRIMARY GPU on the desktop and all programs run using it. This is the first time I've had an accelerated video chip that worked the way it is supposed to. Minecraft, for example, gives me 90-120FPS under Intel but under the 650M I get between 300 - 500fps. With that kind of performance I'll put up with the additional 10 seconds it takes to get to the desktop.
