#StackBounty: #18.04 #notification #notify-osd Notifications never go away

Bounty: 50

Ever since last week notifications will show, but can’t be hidden.

Notifications stay there forever obstructing part of the screen and can’t be closed.

This happens for most notifications and the only thing that hides them is pressing Alt+F2 then restart.

I really don’t know what’s caused this. This is what I’ve tried:

  • sudo apt-get install --reinstall notify-osd
  • Logging in and out.
  • Multiple restarts.

I’m running: Ubuntu 18.04.5 LTS

Any help is much appreciated.

#StackBounty: #18.04 #nvidia #multiple-monitors #dell Ubuntu 20.04 external monitor disconnects after a short period

Bounty: 50

I’m running Ubuntu 20.04 on a Dell XPS 15 9570. I’ve been happily using external monitors on it with minimal issues until today, where it’s suddenly started to shut off the external display after a few minutes, and only recognises it again if I unplug the cable (running over USBC-HDMI)

Some digging earlier made me suspect this error from the syslog was possibly related:

kernel: [ 3012.555110] [drm:intel_dp_link_training_clock_recovery [i915]] *ERROR* failed to get link status

However the only info I could find on this suggested it had been fixed in later kernel versions so it was a bit of a dead end!

How can I go about diagnosing what the cause of the issue actually is, assuming nobody can guess at the cause from this admittedly brief description!

EDIT A bit more context from /var/log/syslog

#StackBounty: #18.04 #unity #mouse #system Mouse clicks do not work for native ubuntu apps or when open folder/file from third-party apps

Bounty: 50

I can not open files or folders from apps like rstudio, typora or chrome. As shown below, when I click "open folders" from typora, the dark grey box will pop up. However, all the buttons do not respond to mouse click except the ‘Cancel’, so that I can not switch folders or select a file.

enter image description here

Similarly, when I open the settings from top menu bar, all the buttons do not respond except the option to close it. If I move the window, it appears as follows:

enter image description here

Restart will temporarily solve the problem. But It will start behaving like this again several days later.

I can’t find a solution on the web. Any help is appreciated.


What I have tried:

I renamed .gnome .gnome2 .gconf (the other two folders were not found) following this link.

Clear cache following this link.

#StackBounty: #18.04 #20.04 #xubuntu #lubuntu Sometimes the mouse becomes unusable and I have to restart the computer

Bounty: 200

Sometimes, randomly (as far as I can tell) I can’t click anything (can still move the pointer). I have to restart the computer to have it running again. Same thing is happening on 2 computers, one is Xubuntu, another is Lubuntu. One is 18.04, another is 20.04. But it also happened on plain Ubuntu as well. What’s going on? It gets really annoying. One mouse is Logitech, another one is from Microsoft. Both are wireless. Btw, important note, the mousepad stops responding to clicks as well during that time. Thanks a lot.

#StackBounty: #18.04 #dell #xps Touchpad on Dell XPS-15-9500 with Ubuntu 18.04.05 LTS

Bounty: 100

I have just installed Ubuntu 18.04.05 LTS on my Dell XPS-15-9500. I have noticed that physical left and right clicks do not seem to work on my touchpad. For instance, when using a scroll bar, I normally would click and then drag the bar to move. This action instead causes the cursor to freeze. Tapping the touchpad does result in left click behavior and two finger tapping results in right click behavior. I have installed gnome-tweaks and enabled "area" mode as per this post: No secondary button (right click) on touchpad. However, I have not found a solution to recover right/left click behavior I described above. I have unsuccessfully searched for a solution and have found mostly ways of recovering touchpad functionality after updates. In summary, how does one enable left and right "physical" click behavior in Ubuntu 18.04?

#StackBounty: #18.04 #python #python3 #sqlite #sqlite3 Is it possible to install SQLite 3.24+ on Ubuntu 18.04?

Bounty: 50

I am trying to update my SQLite version to 3.24 or above so that a Python app can make use of the new “UPSERT” queries. I have been trying for a few hours to do this with little success; it refuses to update past 3.22.

I have attempted:

  • Using apt to install and reinstall sqlite / libsqlite3-dev (and various versions of this)

  • Downloading packages from launchpad (such as
    https://launchpad.net/ubuntu/+source/sqlite3/3.26.0-2) and attempting to install them

  • Using Python pip to try and update sqlite3

  • Adding a few PPA repos to try and grab it from there

  • Other various suggestions found from google

What I have not tried:

  • Building SQLite from source (this is a bit of a last resort for me)

Is it possible to install a version of SQLite 3.24+ on Ubuntu 18.04? If so, is the only way to build from source or is there an easy way to pick up a more recent version through apt (or similar)?

Audio input used to work fine.

I tried restarting pulseaudio with killall pulseaudio and pulseaudio -k, followed by pulseaudio --start

pavucontrol screenshots:

input greyed out

config looks fine

Also I looked up how to list audio input devices and tried that, in case it’s helpful:

That’s my built-in mic right? I don’t know where to go from here.
