Had to reinstall Ubuntu, now it won’t connect to my WiFi at home

I had to reinstall Ubuntu due to it failing to boot (stuck on /dev/sda1 clean …). Now for some strange reason it won’t connect to my WiFi at home (same router as before), although the connection worked during the reinstallation.

Trouble installing ddccontrol

I am running Kubuntu 14.04 on a 32-bit system and I’m trying to install ddccontrol so I can change my monitor brightness without touching the monitor in a GUI. I understand I need to install the CLI version first to get the GUI version (gddccontrol) as is my goal. I have found multiple packages on GitHub and Launchpad and have tried all that I can find. Most of the .deb packages I’ve ran with package…

How to back-up MySQL in a snap

I’ve installed NextCloud in a snap under Ubuntu 16.04 LTS. The MySQL installation in the snap uses a socket file locate in the snap’s (containerized) /tmp rather than a network socket. I don’t want to reconfigure the snap’s MySQL configuration to add a network listener, as I expect that such changes might get lost with upgrades or re-installations. I want to back up NextCloud’s MySQL environment using mysqldump, but without a network listener I need…

What are some methods to fix a broken Unity *session* (no re-login)

The top bar with the applets and the main system menu is missing but, what’s worse, dconf and gsettings have no effect even though dconf-service is running. What methods would you try that don’t apply only on reboot or relogin? If you need to break your session in order to test together with me, just use a combination of unity –reset-icons and killall -9 compiz. It kind of works all the time.

I tried to change the ownership of two folders with the following commands: chown -v lfs $LFS/tools chown -v lfs $LFS/sources At the time the commands succeeded as I saw a message saying the change had been done. Sometime later I checked to see if lfs was indeed the owner, with this command: sudo ls -ld /mnt/LFS/sources and got the following answer: drwxr-xr-x 2 root root 4096 fev 24 17:39 /mnt/LFS/sources Thinking that I might…
