Tenho tido alguns problemas com o desktop do Plasma desde que fiz algumas atualizações. Estou executando o Debian Testing. No último sábado, houve um conjunto de atualizações relacionadas à área de trabalho do Plasma:

Isso quebrou algumas coisas chatas:
Em particular, o carregamento do Systray não é o maior problema. Eu estou em uma perda com descobrir o que poderia ter dado errado e o que eu posso fazer para consertar isso. O problema ocorreu em duas máquinas diferentes, ambas executando o Debian Testing na mesma configuração. Eu não consegui encontrar nenhum bug arquivado no KDE ou no Debian, mas estou relutante em abrir novos, até ter certeza de que não fui eu quem quebrou.
Gostaria de agradecer aos ponteiros de solução de problemas ou soluções.
A questão é 'Debian upstream'. Veja este relatório em bus.debian.org .
Existe uma solução alternativa. Você pode construir o pacote plasma-workspace manualmente a partir do repositório de código-fonte da Debian, que você deve habilitar primeiro.
apt build-dep plasma-workspace apt source plasma-workspace dpkg-buildpackage plasma-desktop.deb resultante com dpkg -i <file>
Eu recomendo que você espere até que o Debian upstream corrija seu pacote.
