Split Files on embedded Linux Systems

If you run a embedded Linux PC like raspi often some Linux Commands fail without error messages, cause the hardware performance is low tech.

Same i have seen on the split command..

to split a 50GB Photos-Archive File to 4Gb on a USB Drive i found out that:

sudo split -b 4096m -d -u Photos.tgz Photos-Archive_

fix the job..
Cause option -u disable IO-Caching over the 2.0 USB Port to the RAM of the raspi that the Data of the Output Stream is written direct to the Drive.

Ubuntu 16.04 Compiz Hang Kernel

After Ubuntu published the latest Kernel Patches for Meltdown and Spectre the Kernel 4.4.0-104/109-generic let Intel Graphics freeze or hang on Compiz with Unity.

Howto fix:

Install the latest Kernel 4.4.0-112-generic

sudo apt-get install linux-image-4.4.0-112-generic
sudo apt-get install linux-image-extra-4.4.0-112-generic



sudo apt-get autoremove --purge -y

This removes older kernels and save Space! Do test the PC for hanging again!!!
