I’ve had this issue where my sound messes up. It seems to happen mostly when I have the Android emulator open. As you see below, I only have the option of using the headset plugged in through my docking station. The laptop speakers are not in the list. If I were to unplug the docking station, I would get “Dummy Output” in the list.
I saw a flurry of articles on Google Now and OMG Ubuntu about Flutter adding the ability to compile to native Linux apps. Since I have been playing with Flutter, I decided to give it a try. I won’t duplicate what they have written. Instead, this article is my notes on enabling my app to work natively on Linux.
The primary purpose of my laptop is programming and building things. I like to dabble in all kinds of things, but most of them are programming related. This is part of my series with my notes setting up Ubuntu 20.04 of my laptop.
This is part three of my Ubuntu 20.04 Install Notes. In this post, I walk through various media-related programs. These are the various programs that I use to work with images, video, sound, etc.
My last laptop was probably the shortest that I’ve ever had a laptop! But, it was time to upgrade. Really, the kids needed something more reliable on which to do their school work. I’m passing the old laptop down to them to hopefully reduce their frustration and get something better for myself.
I selected the XPS 7590. It has 32G of RAM, which will be nice with running virtual machines. It has a USB C port, which I missed on my last laptop. It also allows charging, which is a new concept for me. I learned though that it is a slow charge and depending on what I am doing might not be enough to even power the laptop without using the battery some. It also has an Nvidia graphics card, which will let me play around with some 3D things.
Every new laptop needs a nut name (the first started with the pet name peanut). I named this one hazelnut because of this little tid bit I found on a fact page: “Ancient Greeks believed hazelnuts could treat coughing and baldness.” That seemed fitting for all the stuff going on in the world today!
I tinkered with a few of the BIOS settings, but the only one that I ended up needing to set was the SATA Operation. It’s under System Configuration > SATA Operation. I set the value to AHCI. Apparently, Ubuntu can’t see the partition unless it is set like that.
Initially, I thought I might need to tinker with the settings more because I couldn’t get Clonezilla to boot. It turns out that it was related to the image that I downloaded. Ubuntu had no trouble booting off of the USB drive.
Backing up the Drive
Just in case, I wanted an image of the machine as it came from Dell. That way if I ever need to go back, I could.
I attempted to use the Disks program to make an image of the machine. The only issue is that it required a drive bigger than the 1TB drive that came with the new laptop.
Instead I used this command:
sudo dd bs=1M if=/dev/nvme0n1 | gzip -c | dd of=/media/ubuntu/Seagate\ Backup\ Plus\ Drive/newLaptop/DellXPSDrive.img.gz
So, to restore it, I should be able to run this command (I haven’t tested this):
dd if=/media/ubuntu/Seagate\ Backup\ Plus\ Drive/newLaptop/DellXPSDrive.img.gz | gunzip -c | sudo dd bs=1M of=/dev/nvme0n1
Installing, I chose this:
I also used Clonezilla to back it up because I wasn’t that confident that I did it right. I’ll have to try to restore it into a virtual machine to test it out.
sudo apt install clonezilla sudo clonezilla
You can probably see plenty of screenshots for installing Ubuntu. I pretty much accepted the defaults and didn’t want to paste all of the screenshots here.
The only thing different was the way that I setup the drive. I picked advanced features so that I could encrypt the drive. I would love to try the ZFS, but it doesn’t have the encryption option.
Chrome has been my favorite and comfort zone. Since, I do my documenting in Chrome, I decided to install it first. I downloaded from Google’s website, and then installed it with this command:
sudo apt install ~/Downloads/google-chrome-stable_current_and64.deb
Next, I installed KeePass so that I would have access to all my passwords. I copied the Insync directory, which I use to synchronise the key store. I’ll get it syncing later. Then, I installed the program with:
sudo apt install keepass2
Just so I could get working quickly, I installed VMWare View / VMWare Horizon. I downloaded the client from their website. I installed it with these commands (made it executable, installed python, and ran the “bundle”):
cd ~/Downloads/ sudo chmod +x VMware-Horizon-Client-4.10.0-11053294.x64.bundle sudo apt install python sudo ./VMware-Horizon-Client-4.10.0-11053294.x64.bundle
(During the install, I answered all the questions as yes.)
Finally, I installed Microsoft Teams. Now, that they have a Linux version, I’ll just install the official client. I downloaded it from their website. I installed it with:
sudo apt install ~/Downloads/teams_1.3.00.5153_amd64.deb
First up is the graphics card. It uses the Nouveau driver by default:
I switched it over to the official Nvidia driver. I didn’t have to install any repositories or anything. I just did it from the “Additional Drivers” application.
I was concerned about the Wifi initially based on some of the reviews that I had read. I had no issues though. I just ignored it in the “Additional Drivers”.
The only thing that I have noticed so far that doesn’t work is the finger print scanner. That’s not that big of a deal, and I wonder if it is both a driver issue and a software issue.
I did have a little fight with the Display Link drivers. That’s really more of an accessory issue rather than a laptop issue. I thought that I needed the drivers for the Dock that I bought with the laptop. It turns out that I didn’t. That story will have to come in a later post.
The high resolution screen (3840×2160) is really nice, but I didn’t take into account that it makes things hard to see sometimes. Ubuntu has a setting to scale it up by 200%, but it still leaves some things really small. For example, the 0ad game is hard to read any of the text. The Gimp icons are really small.
One challenge I have had is that my monitor doesn’t support 3840×2160. To have two different displays with different resolutions is a bit of a challenge. I really need the laptop display to scale at 200% and the external display to be 100%. I found the only way to do that was to check the “Fractional Scaling” option at the bottom.
On my last laptop, I had just started playing with the battery tools to try to get more battery time. It seemed to make a big difference, so I thought I’d start out installing it here. I thought about trying laptop-mode-tools, but I found an article with a machine similar to mine.
I installed both tlp and powertop with:
sudo apt-get install tlp powertop
I started tlp and checked the status:
$ sudo tlp start TLP started in battery mode (auto). $ sudo tlp-stat -s --- TLP 1.3.1 -------------------------------------------- +++ System Info System = Dell Inc.

When I turned off the Nvidia card, I was getting some really good battery times. I have yet to actually time it, but it’s over 2 hours, which was the best my other laptop would ever do. Here’s the command I used to turned of Nvidia:
sudo prime-select intel

I have been using Xiphos as my Bible app on my laptop for quite a while. Ubuntu 20.04 left me with quite a surprise when it wasn’t found!
$ sudo apt install xiphos [sudo] password for skp: Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package xiphos
I’m thinking that it has to do with some dependencies that are outdated, but I’m not sure.
I got an email from Let’s Encrypt saying that I am using an old protocol to update my certificates:
According to our records, the software client you’re using to get Let’s Encrypt TLS/SSL certificates issued or renewed at least one HTTPS certificate in the past two weeks using the ACMEv1 protocol. Here are the details of one recent ACMEv1 request from each of your account(s):
Looking on my server, I found that I have version 0.23.0 installed:
$ certbot --version certbot 0.23.0
When I checked to see if it was upgradeable, I did find certbot in the list:
$ sudo apt list --upgradeable ... certbot/bionic-updates,bionic-updates,bionic-updates,bionic-updates 0.27.0-1~ubuntu18.04.1 all [upgradable from: 0.23.0-1] ... python3-acme/bionic-updates,bionic-updates,bionic-updates,bionic-updates 0.31.0-2~ubuntu18.04.1 all [upgradable from: 0.22.2-1ubuntu0.1] python3-certbot/bionic-updates,bionic-updates,bionic-updates,bionic-updates 0.27.0-1~ubuntu18.04.1 all [upgradable from: 0.23.0-1] p
So, I updated it with the apt command:
$ sudo apt dist-upgrade
After it ran to completion, the version was 0.27.0:
$ certbot --version certbot 0.27.0
I tried to verify with this command:
$ sudo certbot renew --dry-run
Long ago, I was using a Google Notebook that has since been killed by Google and migrated into Google Docs. Then, I switched to Evernote for tracking all manner of information. When Evernote decided to limit the number of devices you could use, I switched to OneNote. I was already paying for the Office 365 subscription so it just made sense to me rather than paying for another product from Evernote.
OneNote has never worked on Linux. The saving grace is that they have a webapp that works just fine. I simply pin my work notebook and my personal notebook tabs in Chrome. It gets the job done. Plus, I have the android app so that I can access the information from my phone while out and about.
What’s changed? I’ve gotten frustrated with sync errors. It’s at the point that OneNote is unreliable, and I can’t depend that it will actually save. I left a question mark on the title of this article because I want to change, but I’m unsure of what to change to. So, the decision isn’t quite made yet.
