Plasma issues

[GreyGeek]

As an addendum to the post above I experimented with Iron64, from SRWare, supposedly a drop-in Chromium replacement. I found that on my system it crashes even while setting idle, it crashes opening a webpage or running a YT video, or crashes while that video is playing, etc.... It doesn't close when it crashes. They've merely added code that tests for exceptions and clears the buffer and presents a blank page. Currently, in its present condition, it is not worth downloading. I continue to use the latest version of FireFox. IF it slows down or YT videos begin to display a buffering symbol too often or too long I close FF and reopen it to the same location. It resumes where it left off.

[wonder]

I wrote in a post a couple weeks or so ago that I "no longer cared" if snapd was installed. However, I recently learned that Chromium is sending every URL I put into its URL line back to Google. That bypasses any entries in the /etc/hosts file. So I renewed my resolution to remove snapd and Chromium from my 20.04 install. Also, in a previous post I mentioned that my post-to-working-DE was 11 seconds. Today, because of my disabling and/or masking of all snap services, removing all snapd programs and Chromium, my current post-to-working-DE is 5.1 seconds. (I made improvements since I captured that graphic!)

Below is what I did, as captured from my History lines. The gaps are unrelated commands or commands containing typos and other errors.

In the past I used systemctl list-units to see what snapd components existed.

1845  [B]systemctl list-units[/B]

1853  mount | grep snap

A few hours ago, I installed a fresh install of 20.04.
The first in the first run:

sudo apt remove --purge snapd
sudo apt remove snapd

(this last its not necessary.
After this, any about snapd...

Curious, first open chrome and firefox, not ask or offer the extension for plasma integration...I need install manually...¿?

As an addendum to the post above I experimented with Iron64, from SRWare, supposedly a drop-in Chromium replacement. I found that on my system it crashes even while setting idle, it crashes opening a webpage or running a YT video, or crashes while that video is playing, etc... It doesn't close when it crashes. They've merely added code that tests for exceptions and clears the buffer and presents a blank page. Currently, in its present condition, it is not worth downloading. I continue to use the latest version of FireFox. IF it slows down or YT videos begin to display a buffering symbol too often or too long I close FF and reopen it to the same location. It resumes where it left off.

At this moment, I replace Chromium for Opera, I go to work with Opera to the same works with the chromium.
FF also I use, but not for lot tabs.

Great work of you!
