Q I want user andy to own all files which end in “-img”. What command should I use?
A (Thanks to steeldriver in the Ubuntu Forums) Use this command:
chown andy – *-img
Q When I try to run VLC, nothing happens. If I start it from the command line, I see numerous errors, starting with: VLC media player 2.2.5.1 Umbrella (revision 2.2.5.1~ppa) [0000000001a648e8] core audio output error: no suitable audio output module [0000000001a651e8] core interface error: no suitable interface module…
A (Thanks to mc4man in the Ubuntu Forums) You have mixed vlc packages from 2 ppa's. If you wish to get vlc from a ppa, then just use one. So start with:
sudo apt-get purge vlc-*
Now if you want the 2.2.8 version, then add back the york ppa to your sources, run
sudo apt-get update sudo apt-get install vlc
If you want the 2.2.5 version from my ppa then, after the purge, just re-install vlc.
Q How can I play, or convert (to mp4, ogg, avi …) .dav files? (dav are video files from a security camera).
A (Thanks to nerunja in the Ubuntu Forums) “Media Player” in Mint Linux 18.3 Slyvia is able to play the .dav files fine by default. The media player shortcut shows the command as “xplayer %U”
Q I used to be able to see all my mounted and unmounted internal drives in the left hand pane in Nautilus. Now, after installing 17.10, they do not appear. How can I get all internal drives back on the left hand pane in Nautilus, including the properties dialog?
A (Thanks again to mc4man in the Ubuntu Forums) You can't, this is the direction Nautilus devs have decided to go. If so inclined, you could use a different file manager, such as Nemo.
Q Can you daisy-chain monitors using Displayport?
A (Thanks to sawfish2 in the Ubuntu Forums) Just wanted to share a small success, because I had trouble finding information on using daisy-chained displayport for dual monitors with Linux. Initially I had some trouble to get it working, but, after installing Ubuntu 17.10, and using the correct setting of the monitors (enable DP1.2 in the monitor connected to the motherboard and disabling DP1.2 in the other), it runs to my full satisfaction.
Tips and Techniques Artful and Lenovo
By now, you have probably read about a problem with Ubuntu 17.10 and certain, mostly Lenovo, computers. As I write this, the problem seems to be solved, but it was real, and it was serious.
If you use the current release (as opposed to Long Term Support) of any of the Ubuntu family of distros, your chance of running into this kind of problem goes up dramatically. The LTS versions are tested much more before release, plus you are installing four times as many new releases.
One way to reduce the number of problems is to wait a couple of months before upgrading to the new release. I <i>will</i> upgrade to 17.10, but as of New Year's Day, I'm still running 17.04. I'm letting the early adopters do post-release testing.
Mind you, I don't always follow this advice. Almost a year ago, I had an empty partition on my spiffy new SSD, and a beta release of Xubuntu 17.04 was available, so I gave it a try. It worked so well that I never considered falling back to an older version. I just hope 17.10 provides a similar experience.
