Estou executando o Ubuntu 16.04 LTS, o gnome-shell com o tema adaptt gtk e várias extensões gnome (com ferramenta tweak).
Estou tendo problemas ao iniciar programas (pode estar relacionado ao redimensionamento de janelas?). O Ubuntu congela aleatoriamente quando eu inicio cromo, folga, spotify ou atom (programas que eu uso muito). Às vezes consigo mover o mouse depois que ele congela e posso entrar na CLI usando as teclas ctrl + alt + f, mas não consigo fazer o X funcionar novamente sem reiniciar o computador.
Estou suspeitando que isso esteja relacionado aos drivers de configurações X / placas gráficas. Minha placa gráfica é uma Nvidia (NVS 310) em execução em um computador de mesa HP Z420. Estou usando drivers proprietários da nvidia (atualmente 384.111): Drivers adicionais
Algumas capturas de tela do gnome-tweak-tool para que você possa ver quais temas e extensões eu executo:

Aqui estão algumas informações de depuração do syslog na última vez que o ubuntu congelou:

Depure de um congelamento que eu consegui recuperar depois de esperar algum tempo e mudar de tty (desta vez eu estava começando a folga):

Isso vem acontecendo há um tempo e é muito chato, já que às vezes tenho que reiniciar meu computador várias vezes por dia porque ele não está respondendo. É muito aleatório, pode de repente funcionar por dias sem congelar.
A partir das informações fornecidas e do syslog, alguma sugestão sobre o que posso fazer para tentar corrigir isso?
Obrigado!
