foki's questions

I am using Kubuntu 18.04 LTS on a Dell XPS 13 7390. Recently I got the update needed notification and, as any other user, updated my system promptly. When I rebooted my laptop my touchpad does not work properly anymore.

KDE settings do show that I have enabled "click emulation" and "inverse vertical scrolling" but what the settings show is just not true. Neither click emulation nor inverse scrolling are enabled. I have tried to restore default settings and then to set them again, to no avail.

$ cat ~/.config/touchpadrc 
[parameters]
InvertVertScroll=true
Tapping=true

My current kernel is 5.4.0-84-generic #94~18.04.1-Ubuntu. The last kernel when my touchpad settings worked was 5.4.0-81-generic.

To figure out what was the last working kernel, I needed to reboot into each of the kernels currently installed on my system and make sure whether my touchpad works properly or not.

To get GRUB menu showing on each startup I needed to change the following two lines in my /etc/defaults/grub:

# GRUB_TIMEOUT_STYLE=hidden
# GRUB_TIMEOUT=0
GRUB_TIMEOUT=-1

I have accidentally deleted CPU usage percentage from indicator-multiload menu and now I can't remember what it syntax looks like and can't go back to how it was.

• Possibility 1 (simplest one). Can someone who currently use idicator-multiload and have CPU usage displayed go to Preferences --> Menu items... and paste these few lines in answer?
• Possibility 2. Does anyone know where idicator-multiload stores config file/s. I cant find it in ~/.config ? `sudo apt-get purge indicator-multiload` evidently didn't removed configuration file, I have executed it and then reinstalled package with `sudo apt-get install indicator-multiload` and it restored my (broken) settings.
• Possibility 3. Does anyone simply know the correct syntax wich displays e.g. CPU 34%, iowait [something]?

I have removeded vim-tiny to get full installation following this tutorial and now I can't install vim by:

$ sudo apt-get install vim
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package vim 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 'vim' has no installation candidate

If I simply try to install vim-tiny again situation is same:

$ sudo apt-get install vim-tiny
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package vim-tiny 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 'vim-tiny' has no installation candidate

Output of vim -version is:

$ vim -version
The program 'vim' can be found in the following packages:
 * vim
 * vim-gnome
 * vim-tiny
 * vim-athena (You will have to enable component called 'universe')
 * vim-gtk (You will have to enable component called 'universe')
 * vim-nox (You will have to enable component called 'universe')
Try: sudo apt-get install <selected package>

I have also tried sudo apt-get update and sudo apt-get upgrade and sudo apt-get dist-upgrade and it's all the same. I am using Ubuntu 14.04 LTS. It is very strange situation for me to perform sudo apt-get remove vim-tiny but can't perform sudo apt-get install vim-tiny after this. Any help?

   I've downloaded IntelliJ Idea, then just unziped it and run it by execute idea.sh in terminal and made a new project. I wanted to see what would happen if I simply right click on icon at the left side bar in Unity -> lock to Launcher instead of standard way of making new idea.desktop file also used for making Eclipse launcher icon. And it just made icon on launcher wich runs that particular project. After that I've made idea.desktop icon standard way and it looks like this:

[Desktop Entry]
Name=IntelliJ IDEA
Type=Application
Exec=idea.sh
Terminal=false
Icon=/opt/idea/idea-IC-135.909/bin/idea.png
Comment=Integrated Development Environment
NoDisplay=false
Categories=Development;IDE;
Name[en]=IntelliJ IDEA
X-Desktop-File-Install-Version=0.22

Now when I click on that standard idea.desktop it runs another instance of application (that one which I've made with right click on icon on left side bar in Unity -> lock to Launcher) and it results with situation shown on image below.

I am trying to find this something.desktop icon which I have made with lock to Launcher if any and delete it, but I can't find it in /usr/share/applications.
   

• What Ubuntu actually does when I click on lock to Launcher?
• Whether it creates some .desktop file or something else?
• How can I delete icon made by lock to Launcher?

I have installed Gnome 3 just to try it using this command:

sudo apt-get update && sudo apt-get install gnome-shell ubuntu-gnome-desktop
sudo reboot

After this on log screen I have choice between Unity and Gnome desktop enviroment. Gnome works fine but when I have rebooted machine and loged in a Unity session there was a "mixed Unity". It was Unity with Gnome font, Gnome dialogs and a Gnome look terminal window. Also when I boot machine there is a blue GRUB screen instead of ubuntu purple one. I have tried to restore Unity sudo apt-get install unity but nothing was installed ("...there is latest version..."). Lastly I decided to remove Gnome and tried (from here):

sudo apt-get remove libgtk-3-common
sudo apt-get install ppa-purge 
sudo ppa-purge ppa:gnome3-team/gnome3

#This apt-get remove libgtk-3-common was deleted many things...

Now I can't boot Ubuntu anyway, when I choose Ubuntu from grub (this is dual boot) there is just black screen and cursor in uper left corner. I have tried to automatically update grub by choosing appropriate option in recovery mode.

I really don't want to loose this instalation because there are many settings and software that I really need. How to solve this boot problem and how to remove Gnome?

This is report from boot-repair->boot-repair report.

I also tried to install libgtk-3-common but

libgtk-3-common is already the newest version
libgtk-3-common set to manually installed

And tried to sudo apt-get install ubuntu-desktop

I have solved this unmet dependencies by:

sudo cp /etc/apt/sources.list /etc/apt/sources.list.original
sudo cp /var/lib/dpkg/status /var/lib/dpkg/status.original
apt-get autoclean
apt-get autoremove 
sudo apt-get -f install

and then sudo apt-get install --reinstall ubuntu-desktop works and now I can normally boot a Gnome session but Unity still have some problems. There is no launcher, upper line...

I'm trying to istall AMD/Intel hybrid drivers using this guide and have problem with lib32gcc1 when I'm try to install fglrx*.deb's sudo dpkg -i fglrx*.deb. I get dependency problems with it:

 dpkg: dependency problems prevent configuration of fglrx:
 fglrx depends on lib32gcc1; however:
  Package lib32gcc1 is not installed.
 fglrx depends on libc6-i386; however:
  Package libc6-i386 is not installed.

It says "Package lib32gcc1 is not installed." but look:

sudo apt-cache search lib32gcc1
lib32gcc1 - GCC support library (32 bit Version)
lib32gcc1-dbg - GCC support library (debug symbols)

then I'm tried:

sudo apt-get install lib32gcc1
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 lib32gcc1 : Depends: libc6-i386 (>= 2.2.4) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

also

sudo apt-get -f install
sudo apt-get install lib32gcc1

don't help.

What is the problem? Is lib32gcc1 exists or not? If it don't exists how can I get it to provide installation of fglrx*.deb's?

Has anyone installed correctly Ubuntu 12.04 on HP ProBook 4530s (Radeon HD 6490 M + Intel HD Graphics)?I don't have much time to spend in configurating the system,I would most like to simply install a system that works on my machine.I was tried this 4 months ago but I gave up because of a lot of trouble that I encountered. :(

I downloaded newest driver from Ati site and installed it...

Now at start-up I see a black screen and message:

"Your screen,graphics card,and input device settings could not be detected correctly.You will need to configure these yourself."

I press enter and move to next screen with message:

"What would you like to do?"

and listed below:

"Run in low graphics mode for just one session."

(it is marked) and some other options that could not possibly to mark with TAB or up,down,left,right or shift key... (no cursor). I can not login to system and can not use it! What should I do?

While loging in I chosed "Ubuntu" but when launch My Unity receive message "Ubuntu running in 2D mode..." and some options in compizConfig are disabled. I am instaled ati radeon proprietary driver and now it's activeted but when try to install post released updates then be a problem with installation and can't activate it. ...and i can't launch Ctalyst Control Centre (as one of the reasons stated- the AMD driver is not functioning properly.)...and still can't switch to Ubuntu 3d.
