Ubuntu : Module evdi not found in directory for displaylink-driver.service

J’ai vu que j’avais en boucle dans syslog :

sh[30354]: modprobe: FATAL: Module evdi not found in directory /lib/modules/6.2.0-10018-tuxedo

J’ai donc essayé manuellement avec plusieurs versions mais sans succès :

$ sudo dkms install -m evdi -v 1.12.0
Error! Could not find module source directory.
Directory: /usr/src/evdi-1.12.0 does not exist.

Donc j’ai du me résoudre à prendre sur git et à faire le build :

$ git clone https://github.com/DisplayLink/evdi.git

$ python3 -m pip install pybind11 

$ make

$ sudo make install

make -C module install
make[1]: Entering directory '/home/arias/GIT/evdi/module'

Warning: modules_install: missing 'System.map' file. Skipping depmod.
make[2]: Leaving directory '/usr/src/linux-headers-6.2.0-10018-tuxedo'

Ensuite j’ai fait l’installation manuellement … et maintenant j’ai le displaylink-driver.service qui se lance et le display port qui fonctionne à nouveau.

Mkdocs emoji reduction de la taille

En passant

Répondre

J’ai fini par trouvé (j’ai ajouté css/extra.css ):

img.emoji {
   height: 16px;
   width: 16px;
   margin: 0 .05em 0 .1em;
   vertical-align: -0.1em;
}

.twemoji {
  width: 16px;
  height: 16px;
  display: inline-block;
  vertical-align: top;
}

Et maintenant c’est fixé.

Oracle Linux / Redhat : systemd change /dev/null permissions

Pour fixer le problème des changements de permission sur /dev/null par systemd j’ai fait la commande suivante :

# grep -riL "ExecStartPost" /usr/lib/systemd/system/*service | xargs grep "TTYPath=/dev/tty" | sed 's/:/ /g' | awk '{print $1}' | xargs sed -i '/^ExecStart.*/i ExecStartPost = -/usr/bin/xset -display :0 -dpms s off'

# systemctl daemon-reload

Pour tous les types TTY j’ai ajouté : 

ExecStartPost = -/usr/bin/xset -display :0 -dpms s off

J’ai l’impression que le problème est fixé.
