I use GNOME 40.5 and I would like to ask you how can I add GNOME topbar to secondary monitor too.
This is my desktop:
and as you can see I don't have topbar on secondary monitor, I would like to have clock and system tray here.
is possible to disable file search in Gnome Shell search as you can see on screenshot?
I want only search for applications.
I use KDE Plasma as DE, and I can set presentation mode (to prevent sleeping) in settings, I would like to ask you if I can set it in terminal, because I would like to create script for it.
I setup GPU passthrough, it works, but ubuntu is spamming modprobe processes, it consumes lot of CPU, this is log from dmesg:

I use Kubuntu 18.04, and yesterday I tried to install Nvidia drivers (I use iGPU and GTX 1060), so I followed these commands:
sudo add-apt-repository ppa:graphics-drivers
sudo apt-get update
sudo ubuntu-drivers autoinstall
I didn't reboot, and today when I start my PC I see after boot "Started bpfilter" and nothing happens, I am stuck, I can go to another TTY, so I tried to uninstall nvidia drivers using:
sudo apt-get purge nvidia-*
sudo apt-get autoremove
Rebooted and didn't help, I tried even reinstall xorg and sddm.
This is output from sudo lshw -c video:
I want to use iGPU for my primary display.
I use Ubuntu 18 with KDE Plasma, and I cannot use 2 network interfaces at same time. I have "Wired connection 1" from my IPS (ethernet cable) and "Wired connection 2" using my phone "USB tethering", always works only one interface, if I use phone's connection it works, and if I use connection from my ISP it works too, but if are both connected, only one works, another is like 0 KB/s, I tried several speed tests.

Is it possible to add new items into context menu in Dolphin (KDE Plasma) if I right click on something?
I would like to make a script called Move to applications, which will show only if I right click on a .desktop file and then it will move it to /usr/share/applications/ folder. Or is there a faster way for moving .desktop files to /usr/share/applications/ folder.
I use KUbuntu and I use Breeze theme, I like it, but I would like to use trash icon from Ubuntu 16 (Unity) which looks like this (I have it):
So I created folder Breeze_tomsk (I copied original Breeze icons and replaced trash icon) in ~/.icons/ folder, and I cannot change my icon pack, because in Plasma settings I don't see my icon pack, where is problem?
I just changed BorderlessMaximizedWindows setting in ~/.config/kwinrc to true to hide window title bar and it works, but after restart of my PC my kwin config is reset to default settings, so BorderlessMaximizedWindows is set to false again.
How to make these settings persistent after restart?
Output from inxi -Sxxx:

Desktop: KDE Plasma 5.13.5 (Qt 5.11.1) dm: sddm,sddm Distro: neon 16.04 xenial
UPDATE:
The problem was with Latte Dock: Can I have different BorderlessMaximized windows option between different layouts?
I have some applications (for example LibreOffice) which looks really weird, design like from 90's.
As you can see here: 
How can I fix it, please?
I installed the KDE desktop environment using apt install kde-plasma-desktop. The problem is that I don't have network settings in System Settings:
(source: kde.org)
Of course, I'm missing this from my System Tray as well.
How can I install these settings?
I am using Ubuntu 16.04 LTS and I would like to downgrade Unity to version 7.3.2 (Ubuntu 15) or to version 7.2.6 (Ubuntu 14). I know that there are some dependency issues, but is it possible to fix these dependency issues? So, just in case that this is possible ... how can I downgrade Unity?
Im trying to install Padre (Perl IDE) on Ubuntu using command sudo apt-get install padre
But I get:
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package padre is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'padre' has no installation candidate
Why is Padre removed from repositories?
I would like to install Ubuntu on SSD (I know that i Have to set TRIM, noatime, etc..) But I would like to know if I can check how many GB was written in last day / week / month.
Because I would like to measure how many GB is written every day on SSD if folders /var and /tmp were on SSD. If there would be less than 10GB writes per day I think it is cool and it will not damage SSD much.
And no I don't want to use ramdisk :)
I know, this is quite "popular" topic, but I made some tests with Unity.
I would like to know why Ubuntu 16.04.2 LTS is using 2x more RAM than older versions of Ubuntu?
Is possible to reduce it to arround 500MB of RAM usage? Or is possible to downgrade Unity to lower RAM usage?
For imagine LUbuntu 16.04 LTS uses about 600MB of RAM with same kernel and packages, so it means that 400MB (+ something, because something of that 600MB RAM is LXDE in LUbuntu) of RAM is only Unity. In past release 400MB of RAM was almost whole oparating system Ubuntu with Unity, now it is only a part of Unity?
Please don't tell me to switch to lightweight flavour of Ubuntu, I have enough RAM and I like Unity, BUT I want to know why is it consuming 2x more RAM and of course I want to reduce it (from the principle).
So I made some tests with clean Ubuntu installations (with nothing running in the background) and their RAM usage:
Ubuntu 14.04.5 Trusty Tahr LTS
Ubuntu 15.04 Vivid Vervet
Ubuntu 15.10 Wily Werewolf
Ubuntu 16.04.2 Xenial Xerus LTS
Is possible (any method) to switch between Graphics Cards while system is running? And than disabled card bind to KVM/QEMU?
I have 2 GPUs (1x Intel HD 4600 and 1x NVIDIA GeForce 1060)
I would like to have virtual Windows 7 using KVM with GPU passthrough.
Intel Graphics for Linux (host) NVIDIA for Windows 7 (guest)
I know that i have to set stub for NVIDIA.
I would like to have primary GPU Intel Graphics and use sometimes NVIDIA card using Bumblebee (nvidia optimus).
But problem is that then i cant bind NVIDIA card to virtual machine. Is possible to unbind drivers while system is running? I dont think it is problem, because X server is using primary iGPU (Intel Graphics, not NVIDIA)
Thank you very much
PS: I have a desktop
I installed Ubuntu 14.04 with dualboot. But i have problem with microphone noise. I can not find any noise reduction in Ubuntu.
Sound quality is for me quite important, because i am talking with friends on TeamSpeak, recording videos on youtube and doing livestreams.
I have microphone in headset, and i never had any problem with it in Windows.
I tried alsamixer and PulseAudio Volume Control, but it does not help, because it only lowered my volume, but noise is still here.
Please do not post here applications like audacity, because i need realtime reduction, because livestreams and talking on teamspeak.
PC: Desktop
Sound card: Realtek® ALC892
I would like to ask you, if you know any SIMPLE and LIGHTWEIGHT application for monitoring network?
I am not looking for network activity monitor for servers, like daily stats etc, i need realtime stats.
I mean that it shows how much bytes are incoming and outgoing of EVERY SINGLE APP..
I would like to have that program with GUI.. something like this in Windows:
I would like to ask if there is any list of pre-installed applications in Ubuntu which are safe to remove.
Once, I tried to uninstall unnecessary applications from Software center, but it created some bugs. For example, I lost some icons from System settings, and then I had to do sudo apt-get install ubuntu-desktop to recover lost data.
I would like to remove unnecessary applications, but I don't want to break my system.
I replaced nautilus with nemo file manager, i like nemo much more, but i dont know how to set wallpaper in nemo. If i go to images and right click on image, then select "Set as wallpaper" nothing happens...
