Ubuntu 19.04 is available for download today. With Linux 5.0 and GNOME 3.32, Disco Dingo offers performance improvements and visual enhancements. Whether you are upgrading or not, Disco Dingo is the foundation for future long-term support for Ubuntu.
As always, this latest release of Ubuntu comes six months after the last Ubuntu release, Ubuntu 1
So, should you go to the download site, get a copy and publish it to your main computer? Not necessarily. Disco Dingo is not an LTS version (Long Term Support). Ubuntu 19.04 provides only nine months of support and patches, while Ubuntu 18.04 LTS "Bionic Beaver" is the proven stable desktop environment for the time being.
A faster GNOME 3.32 desktop
Of course there is a new wallpaper. The first thing you'll probably notice is a new icon on your desktop for your home directory. If you do not like it, you can install GNOME Tweaks to hide the home directory icon.
In modern "flat" design, the top bar and the starter of the desktop have a solid black background. The transparent versions of 18.10. Have disappeared.
The application menus have been moved back to the window of the respective application. They are no longer displayed in the toolbar. This is a change in GNOME and not a design decision by Canonical. Some applications always kept their menus in their own application windows, which made the experience inconsistent. There were also some long-standing issues that were difficult to fix. Now this whole initiative has been abandoned in favor of a traditional menu placement – each application menu is located in the application's own window.
Apart from the visual changes, GNOME itself is faster and uses less GPU resources and the upstream GNOME team thanks to the two Canonical programs.

New icons and visual enhancements
The Yaru Icon The set has been updated , and new icons have been added for other third-party applications. This icon set looks more coherent and smoother. There are indications that attention is being paid to the user interface everywhere. Files have received a facelift, they look crisp and feel appealing. That's no surprise.
Even the terminal window has been polished. The GNOME Terminal application has a new title bar with a highlighted New Tab button and a search icon.
The system menu contains a new gearwheel setting icon that replaces the gearwheel icon old icon "wrench and screwdriver".
Application permission controls
The GNOME Settings app now lets you control various application permissions. You can even choose whether or not each application can display notifications.
The Nightlight feature changes the hue of your computer's display and reduces the amount of blue in the backlight when the sun goes down. You can now configure the nightlight schedule yourself.
Updated sound controls
The sound controls have been redesigned. You will not get more functions than before, but the controls are organized more clearly and logically.
Scaling fractional ads (possibly)
GNOME 3.32 supports fractional scaling support, which is of interest to people with high DPI (dots per inch).
In the modified version of GNOME shipped with Ubuntu, the fractional scaling settings are unfortunately hidden or inaccessible to us. A tool may allow access to these settings – or another way to access these settings will be from the user community. After all, they are in GNOME.
Live Patch for Reboot Free Kernel Updates
The Ubuntu 19.04 Software and Updates app has a new tab named LivePatch. This new feature allows critical kernel patches to be applied without rebooting. For users using Ubuntu at home, it is not necessary to install a kernel update on computers that are frequently turned off. If your Ubuntu computer provides an external service or hosts a Web site, it becomes more difficult to schedule the reboot.
Canonical introduced Livepatch in Ubuntu 18.04 LTS, only to remove it again in 18.10. It's now back with this new tab in Software & Updates.
In the 19.04 beta release that was used to test this article, the Software Updates application window has a LivePatch tab, but it is disabled.
Linux Kernel 5.0.0-8 "Shy Crocodile"
The number of Linux kernels has been increased to 5.0.0-8 by Linus Torvalds, but not because of noteworthy code changes. Normally, a significant jump like this would result in an equivalent change in code or functionality. This is not the case. In an email to the Linux Kernel Mailing List, he said:
Changing the numbering does not indicate anything special. If you want an official reason, I run out of fingers and toes to count on, so 4.21 became 5.0.
Torvalds went on to resolve the code changes in Linux 5.0:
About 50 percent are drivers, 20 percent are architecture updates, 10 percent are tooling tools, and the remaining 20 percent are complete (documentation, network, file systems, upgrade) the header file, core kernel code …). Nothing special stands out, although I like to see how some age-old drivers are brought to pasture (* cough * isdn * cough *).
This new core should also be faster because the work accelerated the system was accelerated anti-specter and meltdown code.

Raspberry Pi Touch Support
Most of the driver work in the kernel has been run by video drivers with improved display support Size and Functionality – From the AMD FreeSync NVIDIA RTX Turing to the Raspberry Pi Touch Display. Debian-derived Raspbian Linux already supported the Raspberry Pi Touch display, but now you have the choice to use Ubuntu with your Pi Touch.
The usual software version is being updated
Many software packages have been updated. Here are some of the most important packages in Ubuntu Disco Dingo and their version numbers. Note that Thunderbird stays on the same version.
(The numbers in parentheses are the older versions found on the Ubuntu 18.10 Cosmic Cuttlefish computer that was used to test this article.)
- GNOME 3.32.1 (3.30.1)  Kernel 5.0.0-8 (4.18.0-17)
- Thunderbird 60.6.1 (60.6.1)
- LibreOffice 18.104.22.168 (6.1 .5.2)
- Firefox 66.0.3 (66.0.2)
- Ubuntu Software 33.0.6 (3.30.2)
- Files 3.32.0 (3.26.4)  GCC 8.3.0 (8.2.0)

- OpenSSL 1.1.1b (1.1.1)
Should you upgrade or not?
19659030] It is difficult to provide a convincing argument for an upgrade based on previous findings. The speed improvements are welcome – but not amazing. The visual enhancements are good, but not mind-boggling. There is not much here to set the world on fire what we expected. This is a preliminary build that is not an LTS and delivers what you expect. You get fixes, updated software, a new kernel, and some desktop decorations.
If you've been waiting for a specific solution to a problem that bothered you, especially if it's ad or graphics, you might want to do this by giving Disco a try. If you need the latest software, continue. Ubuntu 18.04 LTS will be supported in the coming years, however, and the next LTS release will be released in a year's time.
Nothing new has been found in the tests that could prevent you from upgrading. But for a PC running Ubuntu in a family house – or anywhere else – I keep coming up with the phrase, "If it's not broken, do not fix it"
