Tried out XUbuntu(My preferred to date) with XFCE 4.16 and fractional scaling. I run a Windows 10 guest with linux in VirtualBox machines and I have a 27inch 4k screen at ~144 DPI.

The fractional scaling is garbage in this setup; and not just because you put the numbers in backwards from what you'd expect(2x is 2x smaller, and 0.5 seems to be 150% larger). It seems like it just scales the rendered output; everything is blurry! Scaling the DPI up to 144 however makes almost everything nice. The term, Chrome, VSCode, Intellij and etc all seem to adjust properly based on the DPI setting. The fractional scaling has a multiplier effect on that though, and so then reducing the DPI makes it smaller but still blurry. It also causes a lot of lag.

So, fractional scaling in XUbuntu seems to be scaling the video output and not just the UI like you would expect. Adjusting this in VirtualBox itself leads to better performance.

My guess is that it was downvoted because it violates two of the comment guidelines: > Comments should get more thoughtful and substantive, not less, as a topic gets more divisive.

Being grateful theres additional options for a well supported desktop experience besides the two dominant parties is flame bait?

Subjective interpretation is now a basis for downvoting and being labelled flamebait.

Meanwhile the most upvoted comment is about the graphic looking like hairy testicles(which it does).

Just opened the page and from the first sentence I had the proof that the ubuntu of Canonical is now a ghost of itself and already far down on the slippery slope...

"22 April 2021: Today, Canonical released Ubuntu 21.04 with native Microsoft Active Directory integration, Wayland graphics by default, and a Flutter application development SDK. Separately, Canonical and Microsoft announced performance optimization and joint support for Microsoft SQL Server on Ubuntu."

So, the major changes done to the distribution is to suck up Microsoft and Google at the same time, and integrate whatever shitty stack that they want to push.

For example, Microsoft SQL, if you are on Linux, you have the full power of Postgres, Mariadb, ..., who in his right mind would willing-fully use Ms SQL on Linux?

And so, going one step further and spend resources to work on that as priority and market it?

As a very long term Linux and Open Source proponent, I have the feeling that it is a hold up.

>Ubuntu 21.04 uses Wayland by default

did they fix all the issues with Wayland on desktop yet? Like HiDPI being broken, Electron-based apps being blurry, broken color management, broken 60+fps, etc etc

Why don't people make the effort to just move to Debian Stable? If you don't want to pay any money, relying on Redhat's goodwill always seemed precarious.

Because there's a big software stack from drivers to scientific software which is being developed for 10+ years (or even longer) for RH based distributions, or for CentOS/ScientificLinux specifically

Software development and verification is huge in scientific computing. It's not just "Meh, let's port it in a weekend and be done with it".

Have they sold the company to Microsoft? "Microsoft SQL Server on Ubuntu delivers an optimised, cost-effective database platform" Of course not, it's not free so it's not cost effective compared to the best database, which is PostgreSQL. Integration with Active Directory group policy seems also a really bad idea since it allows insecure proprietary software to control your Linux machines.

Clearly you're not the audience for these features.

Also proprietary software is not insecure just be being proprietary.

And if that's the extent of your understanding of what the software does, then you aren't really qualified to give an opinion on its security.

I tried Wayland on 20.10 a few month ago and concluded it wasn't ready for daily use. The worst thing is that it would RANDOMLY cause Gnome to restart while closing all my applications. Also the cursor was jumpy and laggy sometimes (especially when opening context menus). Is anyone aware if these issues still happen?

Regarding jumpy mouse, try it with an another one. I suspect some higher end or gaming mice work badly with Ubuntu for some reason. Very jerky motion and missed button presses. Cheap basic mice seemed to work well.

I actually do have a gaming mouse I really like using. Not sure if I want to downgrade for that. It has to be Gnome issue, I've used Sway (Wayland) where everything was super smooth.

The bootloader was broken for this laptop model in 19.10 and I've been deferring going through the same pain upgrading to 20.04. Totally aware of the support situation and upgrade sequence, but an unsupported machine sure beats a bricked machine

You should definitely go to the pain of upgrading to 21.04, since xx.04 releases get updates for 5 years instead of 6 months.

Only every second xx.04, to the best of my knowledge. 20.04 was an LTS release, the next LTS will be 22.04. 21.04 is a standard release supported for 6 months.

Not really disagreeing with the spirit of your comment, but choice of RDBMS is rarely based on the desktop environment of the developers, except in maybe small/hobby projects where the differences don't really matter anyway.

As someone who works in a .NET shop, it's been possible for a while to run MS SQL Server on Linux, anyway. This leads to a smaller overall footprint for those of us using dockerfiles to spin up test environments and such.

Thank you to Canonical for keeping Ubuntu a free and open source operating system with long term support! With the death of CentOS (replaced by an unstable upstream of RHEL) it means a lot to the Linux community.

I fail to see how moving to a rolling release strategy results in any kind of "death", seems like FUD to me. Rolling release, trying to stick to upstream releases as closely as possible, works well with Arch Linux, I'm glad CentOS learned from Arch Linux success. DISCLAMER: I'm not even a CentOS user, but I just like what RH does and has done for "the Linux community" as you call it (I would just call it "society" bu…

The move is pretty transparent to me, when CentOS was effectively "free RHEL" many people who didn't feel they needed support just ran CentOS in lieu of RHEL knowing that they'd get near-100% compatibility without paying a dime.

The fact that it's a rolling release is not really the problem per-se, it's more that you can no longer expect that CentOS n == RHEL n. It's not a drop-in replacement. You can't expect that something that works in RHEL will work in CentOS and vice-versa.

For people who ran CentOS because they liked it over the competition it may not be a deal breaker. For people like me who only used it because it was "free RHEL" the new rolling version is effectively useless. And I'm 100% certain that it's exactly what RedHat/IBM counted on: no more free candy, just buy a license.
