I recently upgraded my Dell XPS (9560) to Ubuntu 1804 LTS from 1604 and I ran into a few issues along the way. This post may help others so I am documenting it here.
Prior to installing Ubuntu 1604 I upgraded the BIOS from Windows 10. Also in the BIOS settings I disabled secure boot and changed the SATA option from RAID to AHCI. If you are following along but doing a fresh install of Ubuntu 1804 over the top of Windows you may need to also do this.
I backup my important folders to my NAS using Deja Dup. I also decided to backup my hard drive to an external 2TB USB drive prior to upgrading. I am glad I did this as I could NOT restore my Deja Dup backup in Ubuntu 1804.
I opted for a fresh install of 1804 rather than upgrade directly from 1604. To install I needed to boot into the live environment and install from there. Installing directly did not work. Installing from the live environment seemed to go ahead without issues. I installed the minimal version of 1804 which I was thankful for as it saved me from having to uninstall all the apps I don't use like the Libre office suite etc..
One of the reasons I chose a Dell laptop was that Dell sell an Ubuntu edition XPS so I hoped there would be good support for hardware within the linux ecosystem. Everything did work out of the box but I still did face some issues that I had to work around.
Once the installation was completed there was a problem with logging in. After entering my username and password the screen would go black and the system was unusable. The solution was to install the Nvidia drivers which I declined to do as part of the install due to my coloured history with the Nvidia drivers.
To install the Nvidia drivers switch to the terminal with the ctrl + alt + f2 keyboard combination from the login screen.
sudo apt install nvidia-390 # Reboot after drivers are installed sudo reboot now
After installing the Nvidia drivers I could now login and use the system.
The first thing I noticed was the fans where running at full tilt all the time. This was very annoying. The battery life is also very dismal when using the default settings so some adjustments are required to suit laptop use rather than desktop use. To be fair this was also an issue with 1604.
Install the powertop, tlp and tlp-rdw utilities.
sudo apt install powertop tlp tlp-rdw
Enable powertop recommendations.
sudo powertop --auto-tune
These adjustments don't survive a reboot so create a service to start on boot.
cat << EOF | sudo tee /etc/systemd/system/powertop.service [Unit] Description=PowerTOP auto tune [Service] Type=idle Environment="TERM=dumb" ExecStart=/usr/sbin/powertop --auto-tune [Install] WantedBy=multi-user.target EOF
Start and enable the powertop service.
sudo systemctl daemon-reload sudo systemctl start powertop.service sudo systemctl enable powertop.service
Finally change the Nvidia video card settings to use the Intel integrated graphics only in power saving mode in the Nvidia control panel. I run Windows 10 on an external USB 3 SSD drive for gaming so I have no use for the NVidia video card in Linux, YMMV.
Putting the laptop into suspend would cause the laptop to lock up and it was not possible to bring it out of a suspended state. Sometimes the fans would also turn on to full speed during this state indicating that it was not actually suspending at all. Some further adjustments to the Nvidia settings where required to fix this issue.
Disable the fallback service.
sudo systemctl disable nvidia-fallback.service
Edit the /etc/default/grub config adding the line GRUB_CMDLINE_LINUX="nouveau.blacklist=1"
Update GRUB and reboot.
sudo update-grub # Reboot after drivers are installed sudo reboot now
My laptop came with a Killer wireless card which is absolute rubbish. My bluetooth adapter would occasionally dropout and be undetectable by the operating system. This was also an issue in Windows 10 so I know it was not related to Ubuntu specifically. The web is littered the complaints from people about these P.O.S cards. The only way to get it back was to reboot but sometimes this was not enough and I had to go into the BIOS and disable/re-enable the bluetooth to bring it back to life.
After upgrading to 1804 the bluetooth was dropping every other day and sometimes daily so I replaced the card with a Intel 8265 wireless card. It cost about $30 delivered and took 20 minutes of effort, I have not had any issues related to bluetooth dropouts since. My fingers are crossed that this issue is now put to bed.
The default Ubuntu theme is pretty bland IMHO and I use gnome-tweak-tools to adjust some of the settings. First I installed the Any Bloody Slim theme. Next I installed the PopOS theme that is provided by System76.
I use Gnome Tweaks to set the Application theme to Ant Bloody Slim and the Cursors and Icons themes to PopOS. Combine this with the Gnome dark theme and a nice background and IMO this results in a very pleasing to look at and use desktop environment.
The following are a list of the core applications that I use.
I use the Hurtado theme for Tilix which can be found here.
Enpass can be joined to Dropbox and passwords synced across multiple devices.
Also install additional packages to play restricted content.
sudo apt install ubuntu-restricted-extras ffmpeg
I also use Enpass, Privacy Badger and Add Block Plus Firefox plugins.
