O Dolphin no plasma 6.1 ainda suporta serviços dolphin? Meus serviços instalados não estão mais disponíveis após a atualização.
Acabei de instalar kde-fulle escolher sddmcomo Display Manager após a instalação, mas não desconectei e mudei o ambiente de desktop para KDE e apenas reiniciei, agora quando inicializo meu Ubuntu vejo uma tela preta.
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:

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.
Eu sou novo no Linux. Acabei de instalar o Ubuntu e depois de remover a área de trabalho de plasma do KDE e reiniciar o sistema. Estou preso em uma tela de comando preta. Não tenho certeza de como chegar à tela padrão da área de trabalho do Ubuntu.
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.

Tentando atualizar o MariaDB
Li que deveria atualizar o MariaDB, mas não sei como.
~$ sudo systemctl restart mariadb
Failed to restart mariadb.service: Unit mariadb.service not found.
~$ sudo mysql_upgrade
Reading datadir from the MariaDB server failed. Got the following error when executing the 'mysql' command line client
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
FATAL ERROR: Upgrade failed

sudo: mariadb-upgrade: Command not found
~$ mariadb --version
mariadb Ver 15.1 Distrib 10.3.34-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2
Então eu corri
curl -LsS https://downloads.mariadb.com/MariaDB/mariadb_repo_setup | sudo bash -s -- --mariadb-server-version=10.8
sudo apt update && sudo apt upgrade -y
~$ mariadb --version
mariadb Ver 15.1 Distrib 10.3.34-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2
Mas, como se pode ver, isso não mudou muito.
Eu li, https://bbs.archlinux.org/viewtopic.php?id=184192 , que a atualização para a versão 10 do MariaDB pode ser o problema. Ele sugere fazer o downgrade e depois fazer algumas coisas e depois atualizar novamente. No entanto, esse artigo é de 2014, então não tenho certeza se ainda se aplica.
AppArmor
De acordo com a atualização para o Ubuntu 20.04.2 LTS quebra o Akonadi e, portanto, o KMail pode ser um problema com o apparmor, então eu corri
sudo systemctl disable apparmor
e reiniciado, mas isso não ajudou.
O que posso fazer?
