Nvidia Ubuntu 22.04 driver error (solution)

After a normal boot, the Ubuntu displayed a wrong resolution and an “unknow” device on display settings.

I searched for the solution for hours and nothing.

So, I decided to try change the recommended driver on “Additional drivers” application to another one with the same number of the version of the GPU. In my case was nvidia-driver-515 that I discovered executing the nvidia-detector command.

Another utility command is the sudo nvidia-bug-report.sh that generates a complete log of the driver, device and so on.

Here is the changing I have done.

Flutter build ipa 1100 error

After many tries of executing the flutter build ipa command and receive always the 1100 error saying that “Your session has expired. Please log in.“, I finally done.

There is a right above the last error message, that says:

Try distributing the app in Xcode: “open /Users/user******/Development/Mobile/[[app folder]]/build/ios/archive/Runner.xcarchive”

And that’s it!

The Xcode application starts and ask if I want to automatically sing in. So I marked this option and Xcode ask to log in the Keypass.

After that I tried again to execute the ipa build and everything works fine!

Two lessons: read all error message, always. And don’t give up, never.

UPDATE:

I had to open the Peferences > Account, click on Manage Certificates And + a new Development one cause the old was expired.

After that I tried run the flutter build ipa command an the log says that I must to Build on XCode. So, a prompt ask for my local password many times and build was success.

And them the flutter build occurs.

Ufa!

Ubuntu Apparmor impedindo MySQL Workbench de guardar senhas

Ao tentar criar uma conexão, me deparei com um erro quando tentava armazenar a senha.

Depois de muito pesquisar identifiquei que se tratava do apparmor, um serviço que garante ou remove privilégios de programas.

O mysql-workbench foi instalado pela Loja do Ubuntu no diretório /snap.

Depois de tentar criar uma entrada pelo apparmor vi uma solução mais simples.

Na apresentação do aplicativo na loja tem as opções de permissões. Depois de acessá-la foi só garantir ao programa a letira/edição de senhas.
