Estou usando o Ubuntu 18.04 bionic e instalei o pacote xfce4. No entanto, quando escolho "sessão do Xfce" no gerenciador de login, ele não me conecta ao Xfce4, mas me leva de volta à janela de login. Por que isso acontece e como posso corrigi-lo?
Onde posso ver a configuração padrão do Xenialkernel? Estou particularmente interessado na configuração de gerenciamento de energia USB, incluindo:
CONFIG_SUSPENDCONFIG_HIBERNATIONCONFIG_PM_RUNTIMECONFIG_PMeCONFIG_USB_SUSPEND
uname -rme dá: 4.4.38-l4t-r28.2+g174510d
Eu tenho problemas para redefinir a senha de root do meu servidor mysql no Ubuntu 19.10: eu segui as instruções em https://websiteforstudents.com/resetting-mysql-root-password-on-ubuntu-16-04-17-10-and- 18-04-lts/ e tudo corre como as instruções dizem até chegar ao passo em que devo fazer o login com sudo mysql -u root. Estou tendo o erro a seguir:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
Eu verifiquei meus endereços de ligação em /etc/mysql/mysql.conf.d/mysqld.cnf. Eu tenho três, eles estão definidos para:
127.0.0.1,
10.0.2.15 (my local ethernet iface) and
0.0.0.0
então eu não sei porque ele não me deixa conectar, alguma dica? Eu configurei
sudo ufw enable& sudo ufw allow mysql- mesmo depois sudo ufw disabllede não me deixar conectar!
Finalmente consegui atualizar minha máquina desktop de 16.04 para 18.04.
E como esperado as coisas não ficaram tão perfeitas. Bem, meu computador ficou travado e não consegui mais desbloqueá-lo depois de iniciar a atualização (então o deixei lá por cerca de 24 horas). E após uma reinicialização, ele fica preso após a tela de login, mudar para um shell me dá:
$ sudo apt update;sudo apt -y upgrade

Eu tenho uma cabeça dupla GeForce GT 520 no meu sistema e estava fazendo experiências com ela. Eu instalei o CUDA 9.1 da NVIDIA e ele disse que eu deveria reiniciar para verificar se meu driver gráfico ainda carrega.
Então, reiniciei e agora o driver gráfico não carregava mais, então desinstalei, limpei e removi automaticamente o cuda novamente e reiniciei novamente, mas ainda não consigo recuperar o X. Eu baixei e tentei instalar o driver NVIDIA, NVIDIA_Linux_x86_64-367.27.runmas ele não quer instalar e, em vez disso, me diz para executar o sudo apt-get install nvidia-396 nvidia-modprobe nvidia-settingsque também tentei, mas ainda não consigo voltar ao meu X.
Como faço para recuperar meus gráficos?

Como posso resolver isso? Estou dentro16.04
Após a atualização de 14.04 para 16.04, o apt-get ficou de alguma forma confuso no meu xenialsistema e não tenho certeza de como corrigi-lo. Isso é o que eu recebo (depois apt update).
Alguém pode oferecer alguns conselhos sobre como corrigir isso?

Preciso de um script que possa ser executado como um usuário que modifique o endereço MAC de eth0. Eu criei o seguinte script:
#!/bin/bash
/etc/init.d/networking stop
ifconfig eth0 hw ether 00:50:56:98:00:19
/etc/init.d/networking start
Eu defini a permissão setuid e atribuí-a ao root:
-rwsr-xr-x 1 root root 110 May 24 14:22 ChangeMac.sh
mas ainda assim me daria a seguinte saída quando eu a executasse como usuário:
$ ./ChangeMac.sh
stop: Rejected send message, 1 matched rules; type="method_call", sender=":1.100" (uid=1000 pid=6746 comm="stop networking ") interface="com.ubuntu.Upstart0_6.Job" member="Stop" error name="(unset)" requested_reply="0" destination="com.ubuntu.Upstart" (uid=0 pid=1 comm="/sbin/init")

Por que é isso? Como posso fazer com que um usuário possa invocá-lo, mas seja executado como root?
