I have just installed Ubuntu 24.04 on convertible laptop.
How do I add more keys like esc, and Print Screen on virtual keyboard?
Attached is image...
I have exhausted all things that I found online trying to fix following on ubuntu 22.04
#apt install libpcre2-dev
The following packages have unmet dependencies:
libpcre2-dev : Depends: libpcre2-8-0 (= 10.39-3ubuntu0.1) but 10.40-1+ubuntu21.10.1+deb.sury.org+1 is to be installed
Depends: libpcre2-16-0 (= 10.39-3ubuntu0.1) but 10.40-1+ubuntu21.10.1+deb.sury.org+1 is to be installed
Depends: libpcre2-32-0 (= 10.39-3ubuntu0.1) but 10.40-1+ubuntu21.10.1+deb.sury.org+1 is to be installed
E: Unable to correct problems, you have held broken packages.
Apparently problem is due to dist-upgrade issue from 21.10.
What I have tried so far:
apt upgrade
apt install -f libpcre2-dev
apt autoclean
apt --fix-broken install
Also here's the output of
apt-cache policy libpcre2-8-0
libpcre2-8-0:

Which I am not sure how to use...?
So, on one of our servers (and we have 154), we saw this log entry:
Feb 21 00:00:03 vps-442 fstrim[3162507]: /boot/efi: 97.8 MiB (102542848 bytes) trimmed on /dev/sda15
Feb 21 00:00:03 vps-442 fstrim[3162507]: /: 15.6 GiB (16687521792 bytes) trimmed on /dev/sda1
Feb 21 00:00:03 vps-442 systemd[1]: fstrim.service: Succeeded.
Feb 21 00:00:03 vps-442 systemd[1]: Finished Discard unused blocks on filesystems from /etc/fstab
And we have corrupted and missing files on that system!
Is it safe to turn off fstrim on vps server service?
Ubuntu 20.04 only lets me exit right screen on exactly matching pixel coordinates where hortizontal screen is placed. (Red square)
It is very frustrating when one monitor is vertical and other horizontal...
Is there some way to make monitor always leave screen when moved to left corner?
If I restart extension Ubuntu Appindicators, then only one icon stays.
Ubuntu is 21.10 and Viber is 16.1.0.37
If I grep Viber in processes, situation is same, before and after restarting appindicators extension...
root@mypc:/home/user# ps -afx | grep Vib

I was upgrading from 20.10 to 21.04 and during setup some prompt popped-out asking me for keyboard shortcut for input switch, and I have choosen (Left Shift + Left Ctrl), and now I can't find it anywhere to change!
On shortcut settings, there is no such (Left Shift + Left Ctrl) shortcut, nothing left/right.
You can only see it under region settings.
I have Audioquest Dragonfly Black, v1.5
It says on their website, when light is blue, it's registered on 48 khz when light is green it's 44.1 khz
When I plug it on laptop under windows, it's blue light, but when I plug it in the same laptop under Ubuntu 20.04 it's green light.
Any ideas how to get it to perform at 48k in Ubuntu 20.04 ?
