 In order to install the drivers of the NVIDIA GeForce RTX 4070 Ti on Fedora 42, I followed the steps on the tutorial:

https://www.if-not-true-then-false.com/2015/fedora-nvidia-guide/

All worked flawlessly.

Configurando Logitech Lift con SOLAAR

 El logitech lift tiene 6 botones y ellos se pueden personalizar usando solaar:

https://github.com/pwr-Solaar/Solaar

En particular me gusta activar con el boton central pequeño (DVI ) el comando para hacer el puntero más visible en KDE que es Ctrl+Shift+F12:

Eso se hace así:

En el menú principal:

• Active Key/Button Diversion: DPI Switch - Diverted

Luego en Rule Editor configure la regla:

• Key >> DVI Switch (Key Up)
• Key Press >> Control_L Shift_L F12 (agregue teclas con Add key) y luego seleccione Click

Save changes y eso es todo.

Para entender esto me sirvió el video: https://www.youtube.com/watch?v=CHbFFvxldG4

No WIFI on ASUS Vivobook 15

This device is not supported by Linux yet!

 

daalvarez@laptop:~/Downloads$ lspci | grep Network
0000:02:00.0 Network controller: MEDIATEK Corp. Device 7902 

 

Check:

https://linux-hardware.org/?probe=97a323caf9

In order to circumvent this problem I bought a USB with the chipset RTL8188FU 802.11N from AliExpress:

daalvarez@laptop:~$ lsusb

Bus 001 Device 002: ID 0bda:f179 Realtek Semiconductor Corp. RTL8188FTV 802.11b/g/n 1T1R 2.4G WLAN Adapter

Linux does not recognize it out of the box. Therefore, I used the drivers and instructions in:

https://github.com/kelebek333/rtl8188fu

with the following modifications (given that they are for Debian-based distributions, and I am using Fedora):

Instead of

sudo apt-get install build-essential git dkms linux-headers-$(uname -r)

Do:

sudo dnf upgrade

sudo dnf install dkms git

Then reboot and continue with ...

sudo dkms install ./rtl8188fu

etc ...

Down below, use the instructions for DRACUT below instead of the ones for INITRAMFS.

Reboot again, and you now have WIFI in your laptop.

Ajustando las ventanas de LXQt

LXQt does not allow to easily resize.

I created some shortcuts that allow to resize a windows easily

$ kate .config/openbox/rc.xml

Then add under <keyboard> the following:

    <keybind key="C-S-KP_4">              # Left
      <action name="UnmaximizeFull"/>
      <action name="MoveResizeTo">
        <width>50%</width>

      </action>
    </keybind>
    <keybind key="C-S-KP_6">              # Right
      <action name="UnmaximizeFull"/>

0.95 = 1600/1680x1050
