Bumblebee: optirun working, primusrun not working

[behpo]

On a laptop with a 940M GPU. It seems it's not a fermi architecture so I installed the regular driver (not 390xx)

optirun glxgears

works

primusrun glxgears
Error: couldn't get an RGB, Double-buffered visual

primusrun steam

....
WORKS ? ... I have tried it numerous times, I don't understand... Maybe after I reinstalled the driver...

However launching a game (even with "primusrun %command%" in the launch option) still doesn't work

edit: well it worked only once

primusrun steam

Thanks for reading!

At first glance, you need to fix your code output, to make reading easier. Read this Tutorial about the basics, please.

@behpo

“optirun glxgears” works

Why not use optirun then?

[behpo]

Thank you.

[behpo]

Anyone?

Primusrun is supposed to give better results compared to optirun. And I can't run any steam games.

I did manage to use primus on this computer a long time ago, and I didn't encounter this issue.

From what info I could find, it might have something to do with 2 drivers being installed, or a conf file pointing to the wrong driver, but I don't know where to go from there.

Or could I do a complete uninstall, and reinstall following a archlinux wiki tutorial? Would it change anything?

[AgentS]

Hi! I am "anyone".

@behpo

Primusrun is supposed to give better results compared to optirun

AFAIK the best is the one that works.

@behpo

This could have been the answer to my previous question, since "Thank you" to nothing I gave you sounds a little ironic and improper.
On Topic, this feels (to me) like a game/steam specific issue and I would suggest a search on game specific forums.
I hope someone else here can help, since a lot of gamers are here. You might add a relevant tag to your topic to drag their attention.

You can try just setting up PRIME so there's no gpu swapping.

[HowTo] Set up PRIME (output offload) with NVIDIA proprietary driver

The latest versions of Xorg, kernel, and NVIDIA driver all support PRIME output but setting this up is a bit of a faff. What follows is a method to get this working on an Optimus-enabled laptop. 440xx update: If you have something which supports driver series 440xx then you should switch to video-hybrid-intel-nvidia-440xx-prime and ignore this guide (unless you want to use only the dGPU). Specify using the dGPU with e.g. prime-run glxinfo. Note: Fermi-based GPUs should use nvidia-390xx inste…

That's what I ended up doing because Manjaro doesn't seem to handle this stuff very well. Otherwise, install Ubuntu, which works without doing anything.

[jonathon]

Manjaro tries to default to bumblebee which works fine for a large number of Optimus laptops.

Ubuntu's approach is to install PRIME by default, so by setting up PRIME manually you're getting the same setup as Ubuntu.

Optimus support is known to be suboptimal in every distro, but that's down to NVIDIA.

[behpo]

I'm an imbecile. For whatever reason I thought bumblebee would give optirun and primusrun. I tried the link you gave, but I must have messed up somewhere and no DM on startup. So I uninstalled with mhwd, reinstalled bumblebee, rebooted (without reverting the changes I made...) and now I can't even type, it's just a non blinking white underscore.

oops.

[behpo]

You're right, sorry about that.

[AgentS]

@behpo

it’s just a non blinking white underscore.

You can still go to TTY and repair, normally.
Uninstall previous driver and install new one (with mhwd).
The Tutorial is a good guide to setup PRIME, just verify the relevant conf files for modules (load and blacklist) to be correct (leftovers might break it).

[kikutaknight]

i had to go through the tutorial twice to get it right as well xD

[behpo]

At first I could login with the terminal and used mhwd to revert the driver change.

But I didn't revert the config files changes I had made.

After reboot, no ctrl+alt+f1 or f3 or f7 or any f will work. F me.

The blinking underscore thingy is frozen. No blink. Static. Sad.

What now?

edit: I tried failback mode, it's the same.

[jonathon]

Use a chroot.

[behpo]

Thanks, I'll try that right away

sudo mhwd-chroot : command not found. I'm trying to understand why, I can see mhwd-chroot installed (nevermind)

[behpo]

Yessss it worked, I feel like a rockstar! Thanks!

Now back to being a good noob and not modifying any default settings.

Optirun here I come. Now I need to understand how to launch steam games with it.
optirun %command% (instead of primusrun %command%) won't work
