Hey, running nvidia 450xx and kernel 5.4, massive stutters and fps drops, cant get the nvidia configs to save [OpenGL high performance and PowerMIzer prefer max performance, saved as .nvidia-settings-rc, edited the xinit:
exec nvidia-settings --load-config-only
exec $(get_session)
Doesnt work.
probably because i chose free drivers by mistake. Im trying to reinstall manjaro but booting from the old usb gets stuck in “ a start job in running for livemedia mhwd script ”
Know of any different way of reinstalling it or solving the drivers issue without having the need for it?. Thanks
Hello,
Can we have a confirmation that by
you refer to the ~/.xinitrc aka the .xinitrc in your home directory?
This in the Live Media or when? If you installed the 450xx by MHWD and previously of that you removed video-linux and rebooted the system, then the nonfree drivers are loaded.
That can be caused by something else. Please provide from your installed system:
inxi -Fxza --no-host
mhwd -li
cat /etc/X11/mhwd.d/nvidia.conf

Yes
I installed manjaro kde from rufus live usb, and chose free drivers :))
wow i didnt know that. Should I uninstall 450xx, remove video-linux, and reinstall?

BTW really appreciate it
Ok, so you have a Desktop PC with iGPU from AMD + dGPU Nvidia GeForce GTX 750 Ti. Your monitor is connected to dGPU and you can’t set the maximum performance.
We can try this:
- disable iGPU from BIOS, but, if you plan later to use that as passtrough or attach more screens to it, i think that might not be what you want.
- depending what you will want, there might be a need to tweak the conf file
- to get things work better with the dGPU and since you use KDE Plasma, this is my proposal:
Test this for /etc/X11/mhwd.d/nvidia.conf but make sure you backup yours, so you can restore it if something goes wrong:
# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig: version 450.66

Since i added the Option "TripleBuffer" "On" in the Section "Device" then, for KWin to use it, we create the kwin.sh file in the correct place with this command from terminal:
echo "export KWIN_TRIPLE_BUFFER=1" | sudo tee /etc/profile.d/kwin.sh
Reboot and if that doesn’t help, then modify /etc/profile.d/kwin.sh to be like this:
export KWIN_TRIPLE_BUFFER=1
export __GL_YIELD=USLEEP
export __GL_MaxFramesAllowed=1
If i’m not mistaken, if you want to use PowerMizer to maximum Performance, you have to enable Coolbits, so i added that too.
Once you have done this changes, run this command:
sudo mhwd-gpu --setmod nvidia --setxorg /etc/X11/mhwd.d/nvidia.conf
Then reboot.

Please don’t do that … I specified where that file has to be and how to create it.

No worries. Is better to keep things consistent so we know where to look next if other issues might rise along the way. The most important is to solve those issues you have.
And if works, then is even better!

Makes total sense…
After rebooting, the kwin.sh stayed the same (with only
export KWIN_TRIPLE_BUFFER=1). So i added the last two lines. Im not sure if thats what you meant
The last two lines, if added, should make things smoother. Also, if none of that helps, try disabling vsync in Compositor settings.
Ohh thats right, I really didnt consider the idea that anyone would write the entire config file so I forgot to add that I also needed to turn off “Sync to VBlan” and “Allow Flipping”. Anyway im rebooting
Okay so i rebooted, the Display configuration has reset, OpenGL Image and the PowerMizer pref mode remain automatic as before, althought theres a new menu available on the latter.
How did i missed that? Please change it to:
nvidia-settings --load-config-only
exec $(get_session)
No need for the exec part. Reboot and test again.

Hahah, my b.
I fixed it and rebooted, its still the same automatic config
I guess i wouldnt mind disabling iGPU.
Apparently you are not the only one with this issue
https://bbs.archlinux.org/viewtopic.php?id=258556
Later i will do a test on my other install.
Alright
thanks.

Im not planning on using 2 screens in the future, but what do you mean with
The passthrough is if you will use one GPU for virtualbox or qemu
https://wiki.archlinux.org/index.php/PCI_passthrough_via_OVMF
Like plugging a 2nd GPU to power the VM?
Exactly! It will use it as if was native.
By the way, have you tried to create profiles for the Nvidia GPU with the gwe from repository? GreenWithEnvy
