Demonstrating this problem on 20.04:
sudo apt install el-get
Run emacs, hit Meta+x and type el-get-install
Get "No Match".
Attempt to solve it:
Run dpkg -l on el-get and observe that there is a start script in /etc/emacs/site-start.d/50el-get.el, which suggests that there is a global configuration that allows emacs to run el-get start scripts.
So why is the script not loaded ("No Match")?
Update:
I switched to melph and installed the desired package that way.
Bluetooth Mouth work fine until sleep. After resuming from sleep however, the mouse will try to reconnect then, failing that, turns itself off.
This issue arose only after updating to 20.10 (from 20.04). In fact, in the past decade, every time when I upgrade Ubuntu to something, Bluetooth stops working.
lsusb says I have
Bus 001 Device 004: ID 8087:0a2b Intel Corp. Bluetooth wireless interface
The mount is Logitech MX Master 2S.
3 workaround works. This post asks for a method to return it to the Ubuntu 20.04 level of experience (that the mouse connects by clicking).
$ echo connect DA:8E:70:A2:34:F1 | bluetoothctl
My Ubuntu 18.04 is set to Spanish:
But man pages are displayed in English, not according to the configuration (Spanish).
$ man cp | head -n4
CP(1) User Commands CP(1)
NAME
cp - copy files and directories
The following is what I tried to get man page in Spanish:
$ LANG=es_ES.utf8 man cp # result is in English
$ LANGUAGE=es_ES:es man cp # result is in English
$ man -Les cp # result is in English
$ man --locale=es cp # result is in English
To verify es_ES is correctly installed:
$ locale -a | grep es_ES
es_ES.utf8
To verify the man pages for Spanish is installed:
$ sudo dpkg -l | grep language-pack-es
ii language-pack-es 1:18.04+20180712
all translation updates for language Spanish; Castilian
ii language-pack-es-base 1:18.04+20180712
all translations for language Spanish; Castilian
To force re-creating man pages
$ sudo mandb -c
After all of these, try the first 3 commands and none of them produces man pages in Spanish.

How can I make a window manager take a screenshot at every mouse click? Preferably taking a screenshot first, then pass the mouse click event to the underlying window.
In Gnome, if I press prt sc a screenshot will be taken and saved without question. That's the effect I want for every mouse click. Also, I probably can't use Gnome since it's a virtual X session which Gnome/Unity isn't designed for.
I will accept solutions for using any window manager, be it twm, fvwm or i3 or anything.
For the convenience of managing note and todo items on mobile, and the Google Voice integration, I use Google Keep.
I hope there is a desktop Ubuntu software which allows me to access my Google Keep notes.
Most Makefile users use the commandline. Thus they have no need of evoking it in the GUI. But Makefile can be used as an administration tool for the users too.
In my case, a clerk is tasked to maintain a document which changes daily, and as soon as she saves the file, the "source" is changed. I want her to convert it to PDF, stamp the PDF with a given template, encrypt it, merge it with a few other files, and produce three variations for different departments with different stamps.
I have a Makefile for that purpose, already written. Is there a way to let her evoke the Makefile without putting me to the mire of doing additional commandline training? She can save the document, evoke Makefile, and be done.
P.S. This is not about how to execute a shell script or an .EXE file because there is no shell scripts or .EXE files or any executable files in the question at all.
If I paste a piece of code from the browser to emacs -nw with middle mouse button, or Ctrl+Shift+v (in gnome-terminal paste from clipboard), it's incorrectly indented.
Original code:
for (i=0; i<=10; i++) {
j = j + i;
print j;
}
Becomes:
for (i=0; i<=10; i++) {
j = j + i;
print j;
}
In vim one would turn off auto-indent. In emacs I tried 2 ways that doesn't work:
Method 1:
Configure ctrl+y to use PRIMARY selection in ~/.emacs
(setq x-select-enable-primary t)
And try to paste with Ctrl-y instead of middle-mouse-key or Ctrl+Shift+V. Result: ctrl-y only pastes from emacs' kill ring, not from external selection.
Method 2: Unmap RET from newline-and-indent:
(add-hook 'lisp-mode-hook '(lambda ()
(local-set-key (kbd "RET") 'newline)))
It works for typing RET (no indent), but for middle-mouse-key or Ctrl+Shift+V auto-indent is applied anyway.
I have a SanDisk SSD P4 32GB and I use ext4. Ubuntu 14.04.
I read that I should execute the trim command from time to time, however, this command doesn't work on my machine:
# LANGUAGE=en_US:en fstrim /
fstrim: /: FITRIM ioctl failed: Operation not supported
I already have discard mount option, but my other computer with OpenSUSE took 30 minutes when asked to fstrim for the first time, suggesting discard option did not function since installation 6 months ago. I intend to trim my Ubuntu machine too to see whether discard worked.
I googled for 30 minutes. All "answers" either say you should upgrade to ext4 or you should use root and OP says "Oh it then works thanks.". I already did both.
When Ubuntu 13.10 decides to turn of inactive screen, it runs an animation for 15 seconds long, slowly dimming the screen.
The purpose, I assume, is to give an interim for human intervention - a user reading the screen can touch a key or move the mouse to brighten up the screen, preventing the turn-off.
However it failed the purpose on my Acer Iconic W500, where the keyboard and mouse are both locked up during dimming.
The user sits sadly and helplessly waiting for the screen to dim to complete black, and then can he light it up with a mouse move or keystroke.
How irritating it is to break the user away from reading a complicated article that forced him still for 10 minutes!
It may be a bug, and is perhaps filed somewhere (a quick search didn't reveal one).
Here I am asking only for a workaround, e.g. to turn off the dimming animation. If screensaver decides to turn of the screen, let it turn it off immediately so the user can quickly wake it up, thus being less a nuisance.
