Questions[intellij](ubuntu)

I'd like to disable CTRL-SHIFT-U on 18.04.2.

Currently, pressing CTRL-SHIFT-U within a text prompt will make an underlined u appear on the screen and pressing keys will not append text to the prompt until Escape or Enter is pressed.

This prevents me from using the default combo in IntelliJ IDE to toggle case, and I do not wish to use something else than the default.

There are countless questions about this on Superuser and Askubuntu. I tried most of the answers, none of them has any visible effect.

Go to Language Support > Keyboard input method system > Set the value to none (some answers suggest pressing the Apply System-Wide button)

or

Add export IBUS_ENABLE_SYNC_MOVE=1 to ~/.profile and then reboot

or

Kill the ibus-daemon process

This one, the process does exist, but it respawns immediately when killed.

Throughout the answers it was implied that ibus was responsible for this behavior. There is even a GitHub issue about this. So I finally caved in and decided to try removing the ibus package by using apt-get remove ibus and apt-get purge ibus, which is suggested by one of the answers.

After rebooting, CTRL-SHIFT-U still does this thing. There is no longer any ibus-daemon process even after startup. If I go to Language Support, there is no longer ibus as a Keyboard input method system option. It is set to none, and only XIM remains as an alternative.

How come the CTRL-SHIFT-U still works even after ibus is uninstalled, and how can I disable it once and for all on Ubuntu 18.04.2?

Since I switched to the snap version (--classic) of Intellij I can't open any external link (to web sites) from this app. Whenever I click a link I receive the following error:

Error - KIO Client

Unable to create io-slave. Can not create socket for launching io-slave for protocol 'https'.

Versions:

• Ubuntu 18.04.1 LTS
• KDE Frameworks 5.44.0
• Qt 5.9.5 (built against 5.9.5)
• snap 2.37.1.1+18.04
• snapd 2.37.1.1+18.04
• series 16
• Ubuntu 18.04
• Kernel 4.15.0-45-generic

I am having problems with the IntelliJ installation. The installer wont create a shortcut so I do have to start IntelliJ every time with the "./idea.sh" command. Which is pretty enoying if you everytime have to navigate there to start IntelliJ.

Version: 2018.2 Build: 182.3684.101

IntelliJ IDEA 2018.2

If I could get some advices/help I would be very thankful. I am relatively new to Linux so I would really love an instruction :S

I can't close the IntelliJ IDEA when it hangs, how can I close it from the terminal?

P.S.: I think this question is different from "How to kill a unresponsive program from terminal?" because IntelliJ's process has name just 'java' so you can't really tell it apart by its name.

My evaluation licence has recently expired for IntelliJ Community edition version 12. I want to uninstall the application but do not have an option to in Ubuntu Software Centre.

I'm currently looking around my file system at what is installed as part of IntelliJ using a few guides related to Mac. I'm using Ubuntu 12.04

Can someone please point me in the right direction?

_{*I genuinely thought I was using Ultimate edition when I posted this question. I subsequently bought a personal commercial licence. If your boss doesn't buy you a commercial one, getting a personal commercial one was worth it for me [as I like to contribute to what I use].}
