Had trouble connecting my MSI Katana to WiFi on BashCoreX live — no connection to the router at all. Turns out the kernel modules msi_wmi and wmi_bmof were interfering.
Running this command fixed it:

sudo modprobe -r msi_wmi wmi_bmof

After that, I just ran:

sudo nmtui

to configure the network, and WiFi worked perfectly!

If you have an MSI laptop and WiFi issues on Linux, this might help.

#modprobe #wifi #msi #katana #nmtui #bashcore #bashcorex #debian #kernel #linux

Solución al error VirtualBox can’t operate in VMX root mode

Tras la actualización en Debian Trixie a la versión 6.12.6 del kernel de Linux he ido a arrancar mis máquinas virtuales de Virtualbox, y Vagrant me ha devuelto el siguiente error:

VBoxManage: error: VirtualBox can't operate in VMX root mode. Please disable the KVM kernel extension, recompile your kernel and reboot (VERR_VMX_IN_VMX_ROOT_MODE)

La extensión KVM del kernel es la que conecta con el sistema de virtualización de Intel, el que usa mi Thinkpad. En un primer momento he intentado desactivar en la BIOS el sistema de virtualización de Intel y reconfigurar el kernel. Eso no ha funcionado, Virtualbox necesita el sistema de virtualización para funcionar.

Luego he probado a desactivar los módulos KVM del kernel:

sudo modprobe -r kvm_intelsudo modprobe -r kvm

Tras la desactivación, Virtualbox vuelve a funcionar perfectamente.

En el caso de un procesador AMD, en lugar de Intel, los módulos a desactivar son los siguientes:

sudo modprobe -r kvm_amdsudo modprobe -r kvm

Con la actualización de virtualbox a la versión 7.0.20 en Debian, el responsable del paquete notifica lo siguiente:

In kernel 6.12, KVM initializes virtualization on module loading by default.
This prevents VirtualBox VMs from starting. In order to avoid this, either add
“kvm.enable_virt_at_load=0” parameter into kernel command line or unload
the corresponding kvm_XXX module.

And the latest Manjaro Live image breaks Broadcom Wifi installation cause tons of modules via modprobe are missing.

#manjaro #broadcom #modprobe

Just wasted some time on the following:

$ modprobe foo
modprobe: ERROR: could not insert 'foo': Exec format error

$ file `modprobe -n foo`
# Looks OK

After some digging:

$ modprobe -v foo
insmod /path/to/bar.ko
modprobe: ERROR: could not insert 'foo: Exec format error

$ file /path/to/bar.ko
# Wrong architecture

(bar.ko is a dependency of foo.ko.

Or rather: was. In a previous, broken, build. Don't ask)

#modprobe

"When entering a list of values, do not insert spaces after commas, or #modprobe will incorrectly interpret values following spaces as additional params."
thx, #linux #manpages for not mentioning that anywhwere.
#TouchPad can be reactivated by reloading #PsMouse module using #ModProbe , This was observed on #Asus #Laptop #X450LCP
For some reason my freshly installed #Debian #Linux does not find #modprobe, which is in /sbin/modprobe. Same for ldconfig. Any idea why? Some paths problem?

Right, I used #modprobe on bcm2835-v4l2 and it now works! 😀

USB é a sigla de Universal Serial Bus. Esta tecnologia criou um
novo método de conectar periféricos ao computador.

Instalar um periférico foi encarado como uma tarefa assustadora,
digna apenas de técnicos ou pessoas com mais experiência. Isso exigia mais do
usuário, pois ele tinha que abrir o computador
