If you use a TP Link Router like 3600, 4300 or a other brand with ATH9K Chipset you should upgrade to OPENWRT 18.06 with Kernel 4.9
Tested: OpenWrt 18.06.0 r7188-b0b5c64c22 / LuCI openwrt-18.06 branch (git-18.210.69179-6df9a57) – Atheros AR9344 rev 2
- more stable
- less load
- no ath9k Wifi Lookup on high transfers
Same seen on other TP Link Routers like 841 Series, remark last Version 13 not supported
Hope that the Freifunk Software will be updated fast!

If you use a Gigablue SAT Box,after some weeks enigma2 will hang up:
edit root crontab:
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.
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!!!
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.
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 \
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 -
- 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“
Current is a UNFIXED Bug on Debian 9.0 Stretch which makes impossible to easy install DKMS Nvidia-Legacy Drivers 304/340 for older Geforce Cards
To run nouveau on upgrade 8.0 to 9.0 go to /etc/modprobe.d and remove MANUAL all blacklist configs (*.conf) of nvidia cause some glued on upgrade and are not purged automatic by the upgrade. Cause they will block nouveau load at boot (xserver-xorg-video-nouveau)
Then run on Terminal:
$sudo update-initramfs -u -k all
- Older Hardware isn’t supported by Legacy Drivers after Nvidia-375!!
- If you not forced to upgrade to 9.0, then WAIT! up to 3 Month! and checkout Bug Lists.
- I tried Nvidia Installer Files too (*.run) they don’t work too, seems a API of the Kernel is changed
- Nouveau Version on Debian Stretch is able to run Kodi (glx)! seen on Geforce 8400GS 256MB
- On Onboard Geforce Chips like older Laptops HOLD Debian 8.0
