udippel's questions

Since yesterday, my grub boot menu doesn't show any longer. 24.4.1. The PC boots straight into kubuntu. The Partition should be there, however, since sudo update-grub shows:

done

Also at cold boot, no menu shows. The data in the W10-partitions seem to be there, I can mount them and read them.

What to do?

I'm looking for passing a variable to script (I know how to do that), that will be echoed by the script in order to slightly modify that variable.

$ [scriptname] foo bar 

where [scriptname] is the name of the program, and foo and bar the two arguments passed. [Edited for clarification, after comment:] The resulting file should be named foo_bar1, but with the option for the user to make minor modifications to this file name that one can't know beforehand. Therefore it could look like

$ [scriptname] foo bar
The output file name will be foo_bar1

And here I wished I could interactively use, like backslash, remove the 1 and replace it by underscore (_) and 2: The output file name will therefore be foo_bar_2 And this would subsequently be a known or new variable in the script, so that the results of this script can be written into an output file called foo_bar_2.
Reason for my question is, that the file names are not just 3 chars, but rather long, and contain specific data. So the user ought not (try to) re-type dozens of characters; often the output file name will be the one as proposed. The user will see it, most often just 'Enter'. Though also have the chance to add own, minor, modifications. [I hope this explains somewhat better what I need.?]

Is this possible? If yes, I'd gladly learn how to do that. And it isn't necessarily only the last number (I'd know how to remove/isolate it). But at times, I ought to be able to also call the output foofoo_bar_2.

Finally, an almost problem-free update between LTS; at least for me. Thanks a bunch!

There are some minor snags. The one that bothered me most was that all my mounts were inaccessible. Reason: all directories with removable devices under /media/memyselfI/ at (auto) mount create two directories, one that belongs to root, and one that belongs to me, with a directory name ending at an appended '1'.

Example: I have my data in mounted folder /media/mymyselfI/ABC. After the restart the auto mount produces two directories:

drwx------ 1 root root 118784 Sep 23 14:41 ABC
drwxrwxrwx 1 memyselfI memyselfI 118784 Sep 23 14:41 ABC1

ABC is empty, ABC1 contains my data. After some umount, and rmdir of the first as root, everything works once again.

Is this correct, or to be expected update behavour?

"Solved" by upgrading from 20.04 to 22.04

I have tried all the suggested solutions,

sudo apt-get remove --purge libreoffice*
sudo apt-get update
sudo apt-get install libreoffice
sudo apt-get install libreoffice-plasma
sudo apt-get clean
sudo apt-get autoremove 

including in different, logically correct sequences.

$ dpkg -l | grep libreoffice
$

What can I do to remedy the situation, please?

No, I haven't locked my widgets. I can move them around freely, I can create them, I can delete them. But I can't resize them and I can't get to their handles. I searched in here, and found two answers, which did not help. So, I did 'tweak' the widgets in DesktopSettings, to no avail. I did an 'unlock' whereever I could have done one (though none was locked). The locks looks like a horizontal eight, in black, barely visible on the lower left side of each icon. I run kubuntu 18.04, daily updated.

The first image shows the lock (?) across the icon. The second image shows some widgets that are open for editing, and some, with names in italics, that cannot be modified.

It looks like -flicker-, but contrary to what I could find in Google, it is not to do with Chrome. It is the log-in screen already that shows up occasionally on the screen, and then the screen turns black again. This is the second, main, monitor to my Thinkpad T410s. On the built-in screen everything is fine. But it is so tiny, I do not use it. I also came across some random shutdown troubles during my search. I do not have any such. I would not say that the display flickers, rather the display shows up for spilt-seconds while the larger part of the time the display is simply black.

As last resort: How would I downgrade from here so that I can use the PC again, please?

Here is - on request - the output of lspci -k | grep -EA3 'VGA|3D|Display':

00:02.0 VGA compatible controller: Intel Corporation Core Processor
Integrated Graphics Controller (rev 02)
        Subsystem: Lenovo Core Processor Integrated Graphics Controller
        Kernel driver in use: i915
        Kernel modules: i915

There are a number of items that I found during the search, like: Ubuntu how can I send my audio output, to the mobile which is connected using bluetooth?

There is an answer with +100, stating that Android lacks the A2DP capabilty. As far as I can make out, in the meantime there is an applet by the name of SoundAbout that is supposed to do just that. I installed it, paired the devices.

And what I get is like the image in https://cjenkins.wordpress.com/2013/07/16/use-a-wireless-bluetooth-speaker-on-ubuntu-12-04/ , except it says A2DP source (Receive Audio)

I have installed blueman, and I get quite a lot, but no other output device ever pops up in pavucontrol. Therefore, everything is and remains quiet. pulseaudio-module-bluetooth is installed.

How can I get to make the sound system see the device?

Thanks in advance!
