Executei esse comandos mas continua o problema ainda aqui O Systemback não abre a GUI dele, só funciona via terminal e o Skype não abre de jeito nenhum Apesar de estar ate com icone no menu para acessar e utilizar Por log não da pra saber o que aconteceu? Mas não sei onde localiza o log de programas inseridos e removidos do Debian Jessie

Com desktop distinto cada um usando Um usando o desktop normalmente E o outro acessando via rede interna ou externa No Windows ou Smartphone Android o outro Desktop Por exemplo se for no Android, vai precisar instalar algum programa nele pra acessar o Debian? Se por exemplo: Tiver o no meu Debian, o usuarios X e Y X esta usando o Debian novamente E Y resolver acessar tambem mas não o desktop de X e sim de Y remotamente via Android O que deve ser feito para Y acessar sem atrapalhar o uso de X Tentei com o Teamviewer mas quando acessa via Android remotamente, ele interfere no usuario que esta usando o Debian localmente

Como faço para reinserir alguns pacotes do DVD do Debian Jessie no Debian Jessie do meu HD?
