XFCE: Lockscreen has low resolution

[PROBLEM] Fresh installation of Xubuntu 18.04.4, GFX card Nvidia GF119/GT520 - Dual screen setup with 2 very different monitors. Everything works fine, screen resolution and offset as it should, BUT: The lock screen looks weird, because it has a quite low and possibly 4:3 resolution (on 16:9 monito...

Linux: Read embedded Windows key from BIOS

I have bought several notebooks that had Windows preinstalled, but the license key was only stored in the BIOS (no more stickers on the bottom like in the good old days). I never used the Windows on the more recent machines, and only have GNU/Linux installed on it. However, I like to know license ke...

Phone hotlines.

Es tut mir leid und Sie sind schon die xte Person heute die mir dasselbe sagt - aber ich kann leider nichts machen. Wir wissen auch nicht warum das so ist.

LaTeX Error: File `booktabs.sty' not found.

[PROBLEM]
Using Pandoc to generate LaTeX from Markdown gave me the following error:
LaTeX Error: File `booktabs.sty' not found.


[SOLUTION]
Whatever was missing seems to be in this package:
Code: Select all
$ sudo apt install texlive-latex-extra


OS was Xubuntu 18.04.4.

APT: Packages wrongly marked as orphaned

Happens (at least to me?) every now and then and I find it a bit "unrelaxing" that sometimes a meta-package is being (marked as?) removed due one of its dependency-packages not being present. There are different situations (perfectly reasonable and legal package install/removal use cases) ...

New design brand label: "Sicherheitshalber"

IDEA: First: Only one word: " sicherheitshalber ." printed on T-shirts, pullovers, etc: Different colors, different styles, different fonts - but the same word. The "." (dot) at the end is important ;) In today's times, this word unfortunately seems to be used (and accepted?) a &...

IPv6: use "/etc/sysctl.d"

Another option that I now find slightly cleaner than modifying "/etc/sysctl.conf" directly, is to use the "/etc/sysctl.d" folder to keep this config separately (and easier to enable/disable it). 1) Create a file called "/etc/sysctl.d/70-disable-ipv6.conf" 2) Put the sam...

Ubuntu: add-apt-repository hangs

[PROBLEM] Trying to add a new PPA, using the (already) good-old "add-apt-repository" just hangs and waits forever. Nothing happens. Probably timeout of some kind. I run into this on every new installation since 18.04, and I keep forgetting what it was. Shame on me... [SOLUTION] APT is try...

Xubuntu 18.04: Bluetooth OFF by default

I'm very happy that recent kernels support bluetooth chipsets properly out of the box! Hooray! But, I like to have bluetooth disabled after boot - and only turn it on manually on demand. Especially on notebooks. On recent Xubuntu 18.04, the following command disables that the bluetooth service start...
