These utility scripts aim to make the life easier for nvidia cards users. It started with a revelation that bumblebee in current state offers very poor performance. This solution offers a bit more complicated procedure but offers a full GPU utilization (in terms of linux drivers).
- Make sure your user belongs to 'sudo' group* (see below for further info)
- Execute
nvidia-xrun [app]
in any terminal - Enjoy
-h, --help
- Print help text-u, --unload
- Attempt to unload Nvidia GPU
*'nvidia-xrun-core' requires root permissions for several key commands such as loading/unloading Nvidia kernel modules
NOTE: Turning Nvidia GPU off is not possible always, mostly because of interrupted nvidia-xrun
commands. If you encounter this issue, run nvidia-xrun -u
or nvidia-xrun --unload
to turn off your NVIDIA GPU.
This fork of nvidia-xrun has been revamped. It has some features the original Witko/nvidia-xrun has not:
-
Run
nvidia-xrun [app]
in any terminal and in any TTY session-
Both graphical & command line environments are supported
-
If executed in a graphical environment, nvidia-xrun finds a free TTY for Nvidia GPU, and gives clear instructions how to switch between TTYs
-
If executed in a command line environment, nvidia-xrun launches the program of your choise in the current TTY using Nvidia GPU
-
-
The following parts are not well supported by this fork:
-
Dry-run support is removed. Maybe added later.
-
Not good support for user-specific
.nvidia-xinitrc
files
The forked nvidia-xrun
depends on ttyecho program.
You can find ttyecho in subfolder 'ttyecho', included in this repository. PKGBUILD script is for Arch Linux and variants.
You should compile ttyecho.c
with gcc
:
gcc ttyecho.c -o ttyecho
Install compiled ttyecho
binary either as a custom package or place it manually in /usr/local/bin/
folder. ttyecho
must be found in your PATH.
- nvidia-xrun - uses following dir structure:
- /usr/bin/nvidia-xrun - the executable script wrapper
- /usr/bin/nvidia-xrun-core - the executable (core) script
- /usr/bin/ttyecho - ttyecho executable (Execute commands in another TTY session)
- /etc/X11/nvidia-xorg.conf - the main X confing file
- /etc/X11/xinit/nvidia-xinitrc - xinitrc config file. Contains the setting of provider output source
- /etc/X11/xinit/nvidia-xinitrc.d - custom xinitrc scripts directory
- /etc/X11/nvidia-xorg.conf.d - custom X config directory
- /usr/share/xsessions/nvidia-xrun-openbox.desktop - xsession file for openbox
- /usr/share/xsessions/nvidia-xrun-plasma.desktop - xsession file for plasma
- /etc/sudoers.d/nvidia-xrun-sudoers - sudoers override for nvidia-xrun to run it without password
- [OPTIONAL] ~/.nvidia-xinitrc - user-level custom xinit script file. You can put here your favourite window manager for example
Usually the 1:0:0 bus is correct. If this is not your case(you can find out through lspci or bbswitch output mesages) you can create
a conf script for example nano /etc/X11/nvidia-xorg.conf.d/30-nvidia.conf
to set the proper bus id:
Section "Device"
Identifier "nvidia"
Driver "nvidia"
BusID "PCI:2:0:0"
EndSection
You can use this command to get the bus id:
lspci | grep -i nvidia | awk '{print $1}'
Also this way you can adjust some nvidia settings if you encounter issues:
Section "Screen"
Identifier "nvidia"
Device "nvidia"
# Option "AllowEmptyInitialConfiguration" "Yes"
# Option "UseDisplayDevice" "none"
EndSection
Obsolete for now
## Automatically run window manager For convenience you can create `nano ~/.nvidia-xinitrc` and put there your favourite window manager:if [ $# -gt 0 ]; then
$*
else
openbox-session
# startkde
fi
With this you do not need to specify the app and you can simply run:
nvidia-xrun
dnf copr enable axeld/nvidia-xrun
dnf install nvidia-xrun
The OBS Repo can be found here
Yes unfortunately running Steam directly with nvidia-xrun does not work well - I recommend to use some window manager like openbox.
When using openbox on a HiDPI (i.e. 4k) display, everything could be so small that is difficult to read.
To fix, you can change the DPI settings in ~./Xresources
file by adding/changing Xft.dpi
setting. For example :
Xft.dpi: 192
nouveau
driver should be automatically blacklisted by nvidia
but in case it is not, nvidia
might not get access to GPU. Then you need to manually blacklist nouveau
following Arch wiki https://wiki.archlinux.org/index.php/kernel_modules#Blacklisting.
nvidia
driver may load itself on boot, then nvidia-xrun
will fail to start Xorg session.
To avoid that, you should blacklist it (see link above).
Also sometimes, blacklisting is not enough and you should use some hack to really avoid it to load.
For example, adding install nvidia /bin/false
to /etc/modprobe.d/nvidia.conf
will make every load to fail.
In that case, you should add --ignore-install
to modprobe
calls in nvidia-xrun
script.
