If you use a Gigablue SAT Box,after some weeks enigma2 will hang up: edit root crontab: $crontab -e insert: 0 1 * * * killall -9 enigma2 && sleep 5 && init 3 && /etc/init.d/samba restart 5 1 * * * wget -O /dev/null -q "IP-OF-GIGA-Box/web/powerstate?newstate=0&type=0" This will restart enigma2 Service, Samba and Webinterface too! Then Enigma is set to Standby! That kodi can access the TV Bookmarks to view TV over LAN! If Standby is not set Kodi hangs!

Under heavy load the Debian Kernel 4.14-13 crashes on high memory load and let the CPU freeze. Not really funny so rollback to older version
Apparmor has a current bug with the Kernel 4.14 on Debian and seems Ubuntu too, it blocks MySQL and other services from clean run. Bug touches Network Stack of the 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 do: sudo apt-get install linux-image-4.4.0-112-generic sudo apt-get install linux-image-extra-4.4.0-112-generic reboot then: sudo apt-get autoremove –purge -y This removes older kernels and save Space! Do test the PC for hanging again!!!
I have often seen that the Unity Topbar of Ubuntu LTS is hidden or not clean loaded after Login. It’s Caching Problem of Unity (Compiz) and Lightdm, if the PC is not clean rebooted or started. Howto fix: sudo rm -fr ~/.cache/compizconfig-1 \ && sudo rm -fr ~/.compiz && sudo service lightdm restart Now relogin and check.. if ok do a Profile Backup! with: tar -cvzf /usb-backup-stick/compiz.tgz \ /home/username/.cache/compizconfig-1 /home/username/.compiz
If you work on older Laptops and you use a Console only System Setup like on Debian there is a Bug on systemd and the console-setup package since years. After reboot all Font Settings seems gone. But the Settings are not real gone, cause systemd does not pull the settings on boot! How to fix? edit the crontab of root by sudo su – crontab -e insert the /bin/setupcon command on “@reboot” means on every boot! @reboot /bin/setupcon > /dev/null 2>&1 save and exit, reboot now now the PC should echo big Fonts for old eyes “Terminus 20×12 Frambuffermode”
