Estou tendo um problema gráfico estranho com o gerenciador de janelas no Kubuntu 14.04 LTS.
Algum tempo depois de usar o sistema, percebo alguns artefatos que afetam o Windows. Estou anexando alguns exemplos
Isso torna o sistema inutilizável: por exemplo, se eu clicar em um ícone no Dolphin, os ícones da pasta "parent" não desaparecem e se sobrepõem aos ícones da pasta que acabei de clicar.
Editar: Esse problema aconteceu novamente, eu notei quando o pc estava rodando por 3 horas. Obrigado ellisistfroh, eu lancei em um terminal os comandos que você sugeriu. Não parece um problema do Xorg. Eu não acho que é um problema de superaquecimento, porque se eu sair / login o problema desaparece. Eu também tentei reiniciar o KWin, mas sem sucesso.

Editar 3: Como sugerido por @ellisfroth, instalei o openjdk-6. Eu estava enfrentando esse problema esta manhã e o problema foi resolvido sem reinicializar.

Também poderia ser esse bug (veja também duplicatas de erros):
link title: Aplicativos Java vazam shmem chunks
Veja também: link que é a referência para o Debian
Se o erro apareceu de agora em diante (informações ausentes de u), isso pode vir de uma atualização confusa.
Você pode justificar isso consultando o seu APT-History:
$ var / log / apt / history.log
$ java -version
informa qual é a versão instalada. Aguardando resposta de você ...
Se o problema persistir, devemos dar uma olhada nos arquivos de log para encontrar erros via Terminal / Konsole (apenas os comandos C & amp; P):
egrep "EE|WW" /var/log/Xorg.0.log*
lspci -nnk | grep -iA2 vga
tail -n 50 ~/.xsession-errors
Não faz sentido adivinhar a partir de agora. Poderia até ser um efeito de superaquecimento ou os sinais de uma placa gráfica. Verifique se há poeira nos ventiladores! Ou alguns PPA.
O.k. Já que agora sabemos que é um laptop híbrido com um Intel HD4000 / Nvidia GT650M - precisamos de mais informações:
