Estou no KDE Ubuntu com Plasma. Gosto de editar meus aplicativos com uma descrição relevante. Como exemplo, aqui está um trecho do .desktoparquivo GIMPs:

Name=GNU Image Manipulation Program
Comment=Image Editor
...

Vou entrar no .desktoparquivo na minha ~/.local/share/applications/pasta e alterar a DESCRIÇÃO para algo como

Name=GNU Image Manipulation Program
Comment=Image Editor and Photo Editor
...

Dessa forma, se eu não lembrar o nome do meu editor de fotos, posso simplesmente digitá-lo photono menu iniciar do KDE e a entrada do GIMP aparecerá.

Isso funciona bem, mas acho que não funcionará nos meus Flatpaks por dois motivos:

  1. Os arquivos Flatpak .desktopsão links simbólicos na minha ~/.local/share/applications/pasta.
  2. Os arquivos Flatpak reais .desktopsão armazenados na /var/lib/flatpak/app/...pasta e as alterações parecem ser substituídas toda vez que um Flatpak é atualizado.

Qual é a melhor maneira de alterar uma .desktopentrada Flatpak (nome e/ou descrição) e fazer com que as alterações sejam aplicadas permanentemente? Como alternativa, como eu poderia pesquisar um nome de aplicativo no KDE com tags que eu aplico (por exemplo, aplicando uma phototag ao programa GIMP)?

Depois de uma atualização há alguns dias, o Okular, que uso com sucesso há algum tempo, parou de exibir qualquer janela quando aberto. O dock e a lista de processos ativos informam que o programa está em execução. Isso ocorre após o programa ter sido aberto e fechado algumas vezes. Reiniciar o computador não ajuda. Se eu desinstalar e reinstalar, volto ao funcionamento normal por algumas sessões e depois o comportamento retorna. Alguém experimentou algo semelhante e alguém sabe o que está acontecendo? Estou executando o Ubuntu 24.04 e a versão do Okular é 24.05.1. Na linha de comando, posso produzir a seguinte caixa de diálogo.

$ okular (algum arquivo PDF)
kf.windowsystem: static int KX11Extras::currentDesktop() só pode ser usado no X11

** (okular:(ID do processo)): AVISO **: (carimbo de data/hora): atk-bridge: get_device_events_reply: assinatura desconhecida

Nada mais acontece antes de eu romper com ^C. Entrando apenas

$okular

resulta apenas no aviso. Nenhuma janela do programa ocorre.

Eu estava tendo um problema ao atualizar o Ubuntu. A verificação do certificado falhou, então pesquisei na internet. Então, pela minha própria lógica e algumas respostas em algum fórum. Executei o seguinte comando:

sudo apt autoremove ca-certificates

Agora, depois de reiniciar meu PC, recebo uma tela tty1 em vez da tela de login normal. Tentei pressionar a combinação de teclado Ctrl+Shift+F7-ou-F8 várias vezes. Alguém tem ideia do que é isso e como resolver?

Estou usando o Ubuntu com o pacote completo do KDE Plasma Desktop. Eu desinstalei o GNOME.

Depois de tentar

sudo apt update && sudo apt instalar ubuntu-desktop

Isso é o que estou recebendo:

Acabei de instalar o Kubuntu no meu laptop e tudo funcionou perfeitamente. Então plasma-discoverparou de funcionar de repente. Quando tento iniciá-lo, a janela aparece por um segundo ou mais como um pequeno retângulo no canto superior esquerdo e desaparece imediatamente depois. Iniciá-lo na linha de comando dá o mesmo resultado com a seguinte mensagem:

Instalei o Ubuntu 22.04 de criação rápida e tudo funciona bem com o Gnome. No entanto, quero mudar para o KDE e instalá-lo, e também está funcionando bem no modo local do Hyper V. No entanto, se eu conectar via XRDP, o Gnome ainda será usado. Alterei /etc/xrdp/startwm.she comentei as duas últimas linhas e adicionei exec startkde:

#test -x /etc/X11/Xsession && exec /etc/X11/Xsession
#exec /bin/sh /etc/X11/Xsession
exec startkde

No entanto, isso não está funcionando e no modo local posso ver esses erros em /var/log/xrdp.log:

[20231017-13:52:43] [ERROR] xrdp_sec_recv: xrdp_mcs_recv failed
[20231017-13:52:43] [ERROR] xrdp_rdp_recv: xrdp_sec_recv failed

[20231017-13:52:44] [ERROR] Sending [ITU T.125] DisconnectProviderUltimatum failed

Também descobri como configurar o XRDP para iniciar o canela como sessão de desktop padrão e tentei

echo "startkde" > ~/.Xclients

chmod u+x ~/.Xclients

sudo systemctl restart xrdp.service

No entanto, isso também não está funcionando. O que está errado?

Acabei de ver o /etc/xrdp/startubuntu.sharquivo e parece que ele também deve ser alterado:

#!/bin/sh
# DESKTOP_IMG: This file was created/modified by the Desktop Image build process
export GNOME_SHELL_SESSION_MODE=ubuntu
export XDG_CURRENT_DESKTOP=ubuntu:GNOME
exec /etc/xrdp/startwm.sh

Eu tentei com

export KDE_SESSION_VERSION=5
export DESKTOP_SESSION=plasma
export XDG_CURRENT_DESKTOP=KDE
exec /etc/xrdp/startwm.sh

No entanto, ainda não está funcionando.

No KDE Plasma, o Konsole não tem opções de aparência... Eu quero ter um plano de fundo semitransparente para o Konsole já que eu uso o neovim e ter a documentação por trás do meu terminal é muito importante em uma configuração de tela única tão pequena.

Não consigo fazer com que nenhum dos prompts su do KDE na minha instalação do Ubuntu Studio funcione. Eu defini uma senha para a conta root através do terminal e fiz logon com sucesso como root através do terminal assim ...

su
{enter password}

Tudo funciona muito bem

Mas graficamente estou preso - A única solução alternativa que encontrei é suno terminal e depois executar manualmente os comandos.

Como posso consertar isso? Há algumas coisas que estou tentando definir que não consigo acessar no momento e estou tendo que vasculhar para encontrar arquivos.
