Eu executo o seguinte comando para livrar recursivamente pastas de caracteres que causam problemas com certos aplicativos, scripts ou em NFS/SMB, ou seja, altere 'para ’, ?para ？(chinese char), :para ：(chinese char), etc.

$ find . -type d -execdir /usr/local/bin/rename "s/'/’/g" '{}' +

( renameé o script perl de Aristóteles Pagaltzis)

O problema é que se um determinado caminho tiver duas ou mais ocorrências dos caracteres acima em dois níveis diferentes, ele falhará ao fazer a modificação na segunda vez, pois o caminho inicial não existe mais, por exemplo, em /data/videos/john's pics/folder/last year's bday/folder/, ele falhará com No such file or directory.devido a ter dois '.

Estou pensando em executar o findcomando acima recursivamente de baixo para cima, mas não sei como fazer isso e se essa é a melhor abordagem.

Usar findou qualquer outro script/ferramenta nix como awk, etc., está bom para mim.

Laptop: Sytem76 Bonobo 15, 2024
PopOS 22.04
NVIDIA GeForce RTX 4080
x11 (not Wayland)

Depois de desembalar o laptop, coloquei o stick NVMe que estava executando o PopOS 22.04 em um laptop Dell XPS 9710. Ele inicializou imediatamente, embora o monitor externo não estivesse disponível, então suponho que estava usando a GPU Intel/integrada. Depois de executar a aptatualização do driver, a GPU Nvidia ficou disponível, mas apresentava terríveis problemas gráficos, onde as partes mais ativas da tela saltavam e eram atualizadas constantemente. Registrei uma chamada com System76, que me aconselhou o seguinte:

Parece que o problema é que você instalou o driver Nvidia para Ubuntu, tentando configurá-lo com Prime. Embora você esteja certo de que este é um laptop Optimus que normalmente usaria Prime, descobrimos que usar nossa embalagem resulta em uma experiência melhor.

# add the system76 PPA
sudo apt-add-repository -y ppa:system76-dev/stable
sudo apt update
# remove the current Nvidia packages
sudo apt purge ~nnvidia
# make sure we are getting the most recent release
sudo apt update
# make sure apt and dpkg were not interrupted
sudo dpkg --configure -a  
sudo apt install -f  
# remove supporting libraries as well
sudo apt autoremove --purge
# install the nvidia driver
sudo apt install system76-driver-nvidia
# reboot the system to start using the new driver
sudo reboot

Eu segui os passos, mas o problema permanece o mesmo, ou seja, tela rasgada ao usar gráficos Nvidia, de alguma forma estável no modo híbrido se houver baixa atividade gráfica e nenhum problema desse tipo com gráficos internos.

Esta é a saída de nvidia-smi:

Deve-se observar que ao executar nvidia-settingsna placa de vídeo Nvidia, ocorre o seguinte erro:

** (nvidia-settings:92652): WARNING **: 21:23:21.908: PRIME: Failed to execute child process “/usr/bin/prime-supported” (No such file or directory)

Esta é a saída de nvidia-settings, procurando por PRIME:

Não sei por que prime-supportedestá faltando, mas quando tento instalá-lo, ele informa o seguinte:
