How to install nvidia drivers on ubuntu

First update your new system

sudo apt-get update 
sudo apt-get dist-upgrade 

ensure what graphics driver your system needs.

ubuntu-drivers devices 

install intel driver first

sudo apt-get install intel-microcode 
sudo apt-get install nvidia-xxx 
That's all.

Note: nvidia-xxx

you must enter the recommended driver version displayed in ubuntu-drivers devices and I must warn you. Updating the kernel may cause you problems, so once you installed that NVIDIA driver, please don't upgrade with this commands (sudo apt dist-upgrade or sudo apt upgrade and sudo apt-get dist-upgrade), please use sudo apt-get upgrade that command will hold new kernel releases.

Running EFL applications under Wayland based on Ubuntu 14.04 : egl wayland example

For correct functionality when running under Wayland you must use the latest versions of all the EFL components under Wayland. As a precursor to these steps you must have downloaded and compiled Wayland as per the building instructions.

Running EFL applications under Wayland based on Ubuntu 14.04 : elm example

For correct functionality when running under Wayland you must use the latest versions of all the EFL components under Wayland. As a precursor to these steps you must have downloaded and compiled Wayland as per the building instructions.

notes

Running EFL applications under Wayland
For applications that use Ecore_Evas directly set the environment variable ECORE_EVAS_ENGINE to either wayland_shm or wayland_egl depending on whether you wish to use the SHM based interface with software rendering or use EGL.
For applications that use Elementary set the environment variable ELM_DISPLAY to wl. You may also set the environment variable ELM_ACCEL to none to use software rendering, or to gl to use hardware accelerated rendering.
For more debug info, please set:
export MESA_DEBUG=1
export EGL_LOG_LEVEL=debug
export LIBGL_DEBUG=verbose
export WAYLAND_DEBUG=1

Running EFL applications under Wayland based on Ubuntu 14.04, compile libdrm, mesa, wayland, weston, efl from sources

For correct functionality when running under Wayland you must use the latest versions of all the EFL components under Wayland. As a precursor to these steps you must have downloaded and compiled Wayland.

Setting up the environment

apt install git autoconf automake libtool autopoint check
Installing in a custom location, system wide install would break things.
export WLD=$HOME/install   # change this to another location if you prefer
export LD_LIBRARY_PATH=$WLD/lib
export PKG_CONFIG_PATH=$WLD/lib/pkgconfig/:$WLD/share/pkgconfig/
export PATH=$WLD/bin:$PATH
export ACLOCAL_PATH=$WLD/share/aclocal
export ACLOCAL="aclocal -I $ACLOCAL_PATH"

mkdir -p $WLD/share/aclocal # needed by autotools
Do not set LD_LIBRARY_PATH as your default, it will break things.
Put the above in a script env.sh and source it in the terminal you wish to build the packages.

Notes

please confirm that struct wl_egl_window definition in wayland and mesa are same.
struct wl_egl_window {

int width;
int height;
int dx;
int dy;

int attached_width;
int attached_height;

otherwise you might got a crash here:

Fix : /bin/bash ./config.sub failed

checking build system type... Invalid configuration 4': machine4' not recognized
configure: error: /bin/bash ./config.sub 4 failed

solution:
autoreconf --install
then configure again.

fix error: wl_display@1.error(wl_display@1, 1, "invalid arguments for wl_surface@6.attach")

wl_display@1.error(wl_display@1, 1, "invalid arguments for wl_surface@6.attach")

root cause:
wl_surface_attach(wl_surface* surface, wl_buffer* buffer, int, int);
((wl_proxy*)surface)->display != ((wl_proxy*)buffer)->display
surface's display and buffer's display were not matched.
wayland server can't find the buffer object in surface's client connection.

solution:
correct source code, let wl_surface and wl_buffer use the same display.
By the way, each time you call wl_display_get(NULL).
you will get a new display.

fixed: embedded-redis: Unable to run on macOS Sonoma

Issue you might see below error while trying to run embedded-redis for your testing on your macOS after you upgrade to Sonoma. java.la...
