Notes on OLED on Linux

Posted on by

OLED screens have had issues on Linux. Main problem is unable to control the screen brightness. It looks like there are some ways to do it now

Looks like icc-brightness should help. Install instructions are from here

sudo apt install -y liblcms2-dev
git clone https://github.com/udifuchs/icc-brightness.git
cd icc-brightness
make

You can run the utility with

./icc-brightness

Installing it will set it up to automatically run on log in.

sudo make install

Log out and back in and it should work.

Linux Screen – Create, Connect, Disconnect, Terminate Sessions

Screen is a handy tool that can help you run scripts on servers remotely without having to worry about the session getting terminated. It seems to operate kinda like a virtual console.

Create Screen Session

Create a new session with a specified name

screen -S SessionName

Example output below. Create session named testsession and print screen sessions.

[bob@localhost imapsync]$ screen -S testsession
[bob@localhost imapsync]$ screen -ls
There are screens on:
3313.testsession (Attached)
1 Sockets in /var/run/screen/S-bob.
[bob@localhost imapsync]$

Disconnect from Screen Session

You can disconnect from a screen session by hitting ctrl + a and then ctrl +d

“ctrl + a” then “ctrl + d”

List Screen Sessions

You can list the screen sessions with

screen -ls

Example

[bob@localhost imapsync]$ screen -ls
There are screens on:
3212.testsession (Detached)
2556.xap (Detached)

2 Sockets in /var/run/screen/S-bob.
[bob@localhost imapsync]$

Connect to screen Session

You can reconnect to a screen session with

screen -r testsession

Terminate Screen Session

To terminate a screen session, connect to that session and then on a clear line hit ctrl + d

Same way as if you were closing a remote ssh connection.
