Startu script Ubuntu 16.04.5 LTS doesn’t work

I have problem with configuring my linux. I always start my script manually after reboot but i want to autostart it, because I can now use watchdog to restart my computer after error.

I have my script that always work when I start it in terminal with sudo and like it supposed it make a screen with app that i opened.


./ROC-smi/rocm-smi -d 1 --setfan 90 ./ROC-smi/rocm-smi -d 0 --setfan 90 ./ROC-smi/rocm-smi -d 2 --setfan 110 ./ROC-smi/rocm-smi -d 3 --setfan 110 ./ROC-smi/rocm-smi -d 4 --setfan 110 cd teamredminer-v0.4.1-linux screen -dm ./teamredminer

So i think i need to use /etc/rc.local to start it with root privileges and i add at the end that line: /home/rig0/ exit 0

Problem is that, it don’t work. I have no idea how to autostart this script because i try crontab -e too and its not working too.

Ubuntu 16.04.5 LTS Input audio sounds as a robotic gargle during videocalls skype, facebook and other services

So here’s the scoop, I could send audios with no problem and hear everything fine when I play them back, but when I make video calls the recieving party cannot understand my audio. The audio is distorted and sounds like a robotic gargle. I’ve tryed various fixes but nothing seems to work. Mainly all the fixes related to audio here on the forum.

Greek tone only works in Dash in Ubuntu 16.04.5 LTS

I recently erased my Lubuntu 18.04 install and installed Ubuntu 16.04.5. While I was setting up the system after the installation, I noticed something strange. That has never happened to me before, even on an older installation of 16.04.

I created a keyboard shortcut and at the description the tone was before the letter. For example, the Greek word for “Good morning” is “Καλημέρα” (kalimera). When I type in the Dash it’s fine, however, when I type outside the Dash it shows up as “Καλημ´ερα” (the tone does not “belong” to the letter).

Can anyone help me? Because I am really baffled.

P.S. Anyone is welcome, but because I’m Greek, if there are Greek people on here that know how to solve this I would really appreciate it. Just wanted to make it clear so that there are no misunderstandings.

How should OpenCV 2 be installed on Ubuntu 16.04.5 LTS?

I need OpenCV 2 for a legacy program, specifically OpenCV I have attempted to install python-opencv= and libopencv-dev= The former appears to install, and when I try to install the latter, having removed its OpenCV 3 equivalent (which has recently become the default), Ubuntu retains some unmet dependency problems which seem to arise from removing OpenCV 3. I have attempted to install libopencv-legacy-dev, which appears to install, but then I am met with the standard OpenCV wrong version error: ImportError: No module named cv2.
