Ubuntu 18.04 LTS out!

Downloading/subbing for comments- not sure what to make of this, but want to drop it into a VM anyway :)
 
I know what I'll be doing tonight... and no I don't mean just looking at dirty videos.
 
Should be a very nice release. Especially Ubuntu MATE and all of it's new HiDPI glory. Ubuntu MATE is tempting me away from Solus which is a very hard thing to do.

I'll be waiting a few days to let others deal with the inevitable upgrade issues before I upgrade my Plex server from Ubuntu 16.04 to 18.04. ;)
 
So installed Ubuntu MATE on a spare laptop at the office. It really is nice. The HiDPI scalling works well. The defaults in general are sane. The pre-installed applications are useful and don't feel like bloat.

The Desktop Layouts under MATE Tweak are top notch.

My only gripe with MATE at this point is the default Marco with the adaptive compositor which is the default. It only uses hardware acceleration if your video driver can use DRI3. Modesetting in Xorg defaults to DRI2 for Intel chips because Xorg is dumb. So this gives you tearing. There are two ways to correct it. You switch to marco-compton or marco-compiz or you add this to /usr/share/X11/xorg.conf.d/20-intel.conf

Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "DRI" "3"
EndSection
 
See, I plan to stick with Mate 16.04 until all the issues with 18.04 are well and truly ironed out and then Vermilion goes and tells everyone how good the HiDPI scaling is! Now I want to try 18.04 with a 4k monitor. :(

I use Marco-Compton GPU compositing on both my Nvidia and Intel GPU equipped platforms and don't experience any tearing at all, is there an issue running Marco-Compton over the default setting?

Not at all. I myself prefer Compton. This is just one of those things that bothers me. What's the point of making the default window manager hardware accelerated with DRI3 (and announcing it as big part of MATE 18.04) if the system is going to fuck it up with modesetting?

Bad user experience. If I was a new user it would piss me off to see tearing. Sure many of us know to use Compton or Compiz or even use Google to figure out the 20-intel.conf thing but a new user wouldn't.

Another good example of subpar UX is the gnome-shell memory leak right now. Seriously? Why isn't that shit fixed already?

"Might be backported to 3.28"

MIGHT!? Holy horseshit....

two major Ubuntu releases with 18.04 have bad UX right out of the box with one being Ubuntu "proper" itself. Totally unacceptable for an LTS release and certainly not the way we want to introduce Linux to a new user or any user, even experienced ones, for that matter.

I think they use the software rendering WM by default to avoid any compatibility issues?

It's interesting you mention the memory leak in Gnome, I encountered the memory leak about 12 months ago, yet when I reported it in the relevant forums I was basically told I was crazy - As a result i formatted and installed another distro. You know the Gnome developers, they believe their way is always the best way and the opinions of the users or even the contributors doesn't matter. They probably honestly believe the memory leak isn't their fault and there's nothing wrong with their DE.
 
Vermillion, is it possible to see a screen shot of the Mate HiDPI settings?

From what I was reading and from what Martin Wimpress (MATE lead dev) said the new Marco should be hardware accelerated by default if the GPU supports DRI3. Problem is modesetting is ignoring DRI3 and forcing DRI2.

With DRI2 and DRI3 if 3 is unavailable it will fall back to 2 with no issues. So in this case with Intel, during setup they could set it so they create the .conf file if it is an Intel GPU. If the GPU doesn't support DRI3 it'll just fallback to DRI 2 and work just fine.

Ah, I understand! I agree that it's very frustrating when things don't work correctly out the box as swinging users testing the waters with Linux are easily scared away. The same frustrates me with vanilla Ubuntu, I don't know whether it's improved or not, but the last time I tried it the software center was a buggy mess and didn't want to install third party .deb's at all! They could have at least installed Gdebi by default! Even in the Linux sub forum there's a post from poor Deadjasper struggling because Mint doesn't appear to come with Samba installed by default - Very annoying. Having said that, the Ubuntu Mate devs are pretty switched on and most of the time the distro works pretty well straight out the box.

If you get time whenever I'd love to see a screenshot. Otherwise don't stress, I've got no intention of cracking the whip and demanding - Just very interested is all. ;)
 
Installed in on my Dell Precision m3800 laptop. Works great. No more high dpi issues with my 4K display like with the previous versions. Really liking MATE too. I can’t find anything I don’t like about it.

With a Precision I'm guessing Nvidia card? Using Nouveau or NV drivers? Any tearing out of the box with Marco?
 
I've been using NV drivers on my desktop under 16.04 and have never experienced any tearing.

The AMDGPU open source driver is quite impressive. It's better than the old fglrx driver. https://www.phoronix.com/scan.php?page=article&item=amdgpu-radeonsi-fglrx&num=1

I've got an older AMD A8 system I use the AMDGPU driver on and it's world's better than the older driver. Playing something like DOTA2 is noticeably better with AMDGPU vs the old driver on that system.

Maybe it has changed but when 17.01 was launched the performance was abysmal and it had heavy screen tearing. I had to switch to compton to fix it. I don't have AMD personally but my father in law does in his laptop. We live 2000 miles apart so I had a bit of a stretch when we visited there last time and I upgraded his lappy :D
 
I am using a 4 year old amd a4 and 18.04 works perfectly for what I do but I am not playing games.
 
I see what you did there it says mine is 30% ram at rest.

Running Vanilla 18.04 on my desktop and laptop. On travel from work, so the screenshot is from my laptop. Memory usage in GNOME really isn't too bad considering how big it is. I also have 6 extensions loaded. So far, I'm quite impressed with 18.04 and I only have one gripe. While I like snaps, vanilla Ubuntu is super snap happy. Four of the default system utilities following a minimal installation are snaps. And I'm not talking uncommonly used applications, I'm talking System Monitor, Calculator, and a couple others. I have two issues with this. First, snaps don't integrate well into whatever theme you're running unless it's Adwaita. Second, I just don't see the point. Why not install the native versions of those applications? What is gained by using the snaps? Needless to say, I removed the snaps and installed the native packages. Also, another thing I don't like about snaps is how big a df listing or the file systems tab in system monitor gets with a bunch of snaps installed.

This messes with my OCD also, but you have to look at the bigger picture. If Snaps make it easier for developers and increase security on an already very secure operating system it's a win for Linux as a whole. :)

Mazzspeed is 100% right. By making them snaps they can also update/modify those apps without changing the LTS release underneath. I have heard on multiple podcasts, from Martin Wimpress, that Canonical is aware of the theme issue and they are looking into a solution. Canonical isn't stupid. They know people want everything to be uniform. They just have to make it happen securely. It'll happen. Just give them time. :D

Oh yeah, I agree. Don't take my comment as being down on snaps as a whole, I just don't think they're ready to replace system utilities yet. I love having apps like yakyak and others as snaps, but until snaps are invisible to the end user I don't see the advantage currently. For me anyway.

Would have worked if they just used flatpak like everyone else. ;) half joking. I agree that they will probably find away to implement support. In flatpak terms you have to have the theme installed via flat as well which is not a perfect solution either. I'm not sure exactly how to fix it with no snap/flat themes but I'm sure people smarter then me are on it.
 
This computer I am using is better than the one I had before, AMD A6 compared to A4, and I have firefox and three tabs open and ram use is 35% steady. I don't think it's a resource hog or anything it just is intense on weaker systems. That's the way the winds are blowing, they don't even make many 32 bit os anymore (with good reason just saying sucks if you have one of those machines).

Got the upgrade on my workstation. Didn't get long to play with it, but I was surprised my triple monitor setup remaining working after restarting (I've had a lot of issues getting the screens to stay in the right order previously). Want to play with it more, but it looks solid so far.
 
Been playing with it for a few days now installed on my Surface Pro 3. It's kind of weird. All the primary systems were supported out the box. Type Cover, trackpad, pen, hell it even picked up the accelerometer and seems to rotate reliably though a lot screen tearing in Chrome in portrait mode. It doesn't seem to have any idea about sleep. Press the power button and it wants to shut down the machine. Close the Type Cover and I have to reboot. Scaling works basically, I have it at 200% and all Libre Office is fine. Steam and Spotify totally ignore the setting and just scale at 100%.

Not expecting this all to work and I know folks will freak out over about using a Microsoft device, but clearly someone has been working on this stuff because this is the best out of box experience I've had with Ubuntu on this SP3. But without hardware vendor support things will probably never be perfect. At any rate this will be my permanent Linux/Windows Insider test machine so I'll see what I can figure out about these issues.
 
Go into Steam settings > Interface and tick 'Enlarge text and icons based on monitor size'. I've used it under a 4k VM running Ubuntu Mate 18.04 and it works. Getting in before you say it, fractional scaling doesn't work under Xorg.

Thanks, that was the first thing I tried to no effect. 100% scaling regardless of the desktop setting.

I am aware, I actually do follow Linux stuff around here to learn stuff even when I voice my opinion. Out of the box with this setup, scaling is essentially busted, I'll do some research. On the plus side, it seems like the Type Cover issue improved with some automatic updates. Still flaky but after a couple of opens and closes and hitting power button when the screen light comes on gets me back in without rebooting.

Scaling is essentially busted period. How are we in 2018?!?! 4K has been a defacto norm for years now.
