How is the screen tearing fix in Marco working out for folks with NVidia GPUs?
According to https://youtu.be/iVzGZo5kS8c?t=903 the ForceFullCompositionPipeline setting was still needed to prevent tearing in 19.10 beta.
Due to of some changes in
bash-completion and/or maybe
mawk our LiveCD and installed system are affected by the following bug:
umount /dev/ with Tab does not work and gives error instead of completion:
$ umount /dev/awk: line 18: function gensub never defined awk: line 18: function gensub never defined
I have already reported it as bug
but the reaction on launchpad is very disappointing, no one wants to take responsibility and recognize a bug in some package.
Please do the following:
umount /dev/and then press Tab to confirm the error
Note: installation of
gawk package fixes the issue, but it is not installed by default.
Going back to noveau is not an option for many, unfortunately. The performance gap (especially on non-Kepler GPUs, which can't even be re-clocked manually) is just way too large.
I would recommend adding this to the 19.10 release notes, though, just so people are aware of this limitation.
Unfortunately right now you have to opt between a nice screen tearing free desktop experience or high performance games/ professional 3D modeling with tearing.
As I do not run games, and professional 3D can be used on Microsoft Windos if necessarily, I don't need Nvidia proprietary driver, and I enjoy Tear Free Mate Desktop/Firefox Browser on it entirely. And desktop /Browser run fast like on Proprietary Nvidia.
You can fix the screen tearing on the proprietary NVidia drivers as well, but it requires extra steps:
@maximuscore thanks for the tip, I will give it a try, as proprietary driver keeps my video card at low power use than nouveau at common desktop use (as I see a small difference in fan speed).
I tested in the past different guides from internet, none of them work with Marco, the only thing that work it was called "Compiz", but it has small glitches on Mate, while Marco run absolutely perfect.
Hi from first-time poster
I've just installed 19.10 beta on my Asus Transformer and the screen is in portrait mode and does not make use of the accelerometer to rotate the screen and touchpad. This is not a regression it also happens with other older versions of Ubuntu main and flavours.
But I'd like to try to see if we can get it fixed.
Thanks to this post: https://linuxappfinder.com/blog/auto_screen_rotation_in_ubuntu
I found that by installing
iio-sensor-proxy inotify-tools and running this script (slightly modified from the example) it both switches to the correct orientation and adjusts to future changes.
#!/bin/sh # Auto rotate screen based on device orientation # Clear sensor.log so it doesn't get too long over time > sensor.log # Launch monitor-sensor and store the output in a variable that can be parsed by the rest of the # script monitor-sensor >> sensor.log 2>&1 & # Parse output or monitor sensor to get the new orientation whenever the log file is updated # Possibles are: normal, bottom-up, right-up, left-up # Light data will be ignored while inotifywait -e modify sensor.log; do # Read the last line that was added to the file and get the orientation ORIENTATION=$(tail -n 1 sensor.log | grep 'orientation' | grep -oE '[^ ]+$') # Set the actions to be taken for each possible orientation case "$ORIENTATION" in normal) xrandr --output DSI-1 --rotate normal ;; bottom-up) xrandr --output DSI-1 --rotate inverted ;; right-up) xrandr --output DSI-1 --rotate right ;; left-up) xrandr --output DSI-1 --rotate left ;; esac done
Is it possible to include something of this kind into the image? I realise that DSI-1 is specific to my Asus setup so some detection would be required for this to apply to all units with an accelerometer.
Thanks in advance
No, you don't.
I know you're thrilled that the new compositor in marco fixes YOUR tearing, and that's great, but (a) it doesn't work for at a minimum some Intel IGPs; and (b) there's nothing stopping people from using Compton (or even Compiz, if they want that) just the same as before, and if that means not losing half the performance of their very expensive video cards it's a more than valid reason for them to do so.
I noticed that the icon of the "Advanced Mate menu" can no longer be changed and is now set to the icon provided by the theme as "start-here".
The change was asked here as "an option":
The problem I have is that I want to use "Numix circle" as my theme, but I don't want to have a red circle with an "n" in the panel (the left part of the image is my current setup and the right one is UM19.10 running in a VM).
Numix is a theme that can be applied to many distributions. They provide a generic "start-here", a version for Arch ("start-here-arch"), a version for KDE ("start-here-kde" and a symbolic version "start-here-symbolic".
If they decide to make a version for mate, it will not be used unless they called it "start-here" or I overwrite the icon.
I think this option is fine only for themes made specific for Mate.
You know @arQon maybe you are not so thrilled about this Marco tearing free experience in 19.10 but I really am. I am not a programmer, just an engineer, but I own two workstations one desktop one laptop and a netbook that I run quite often of course I own another desktop use by my mother, and another laptop and netbook that I use really rarely, plus another 3 32bit laptops that are almost no more used, plus two home servers and 3 raspberry pi. All of them have Ubuntu Mate.
From My main PC's use, all of them except the netbook (not counting pi and servers) have screen tearing fixed with Marco. My old laptop have an ATI video card, on that one is not fixed, I don't care as I can use Compiz on it, and is also very rarely used.
The workstation for my use are quite kick as both have some old nvidia quadro GPU's and 6 core xeon processors but if scrolling in firefox is shi... (using a logitech free scroll wheel) video run like garbage with screen tearing on Nvidia Quadro what the fu..., I don't give a... on video performance as the all desktop experience it was junk.... so use Compiz witch solve those issues but bring others, (Compton was worse )... so in the end every time I found myself switching between Marco and Compiz, and in the end for my workflow remain most of time with Marco as it work perfect except screen tearing.
I don't know how you see this but right now my main system desktop run marvelous with Marco and I don't give a shi.. that my Quadros run almost on idle, I just enjoy the smooth desktop experience in 19.10. Quadros was intended for Windows professional apps, some run also under wine, but not as good and also without "space mouse" devices.
You wont both, there is another option, is called KDE, that is not a Linux desktop (neither Windows), you can install it on Linux but is not intended for Linux users as is hard to do basic Linux staffs like running scripts, ssh automatic key authentication does not work without extra manual configuration,.....
I don't say that maybe in the future Mate will use video acceleration by using OpenGL ore something else but is not the case now, and I am really happy that it works very good now, this desktop is almost perfect.
start-here button, we could submit one for
start-here-mate to the numix project. We can change the icon to load that one with fallbacks. GTK allows you to load icon fallbacks by removing hyphen parts: start-here-mate -> start-here -> start -> missing-image, so this should satisfy pretty much all themes.
As to why we changed it, the old icon didn't adapt to theme changes, and so we had to include an icon for light and one for dark themes. Plus a bunch of code to support this option. Using this new icon removed like 500 lines of code, if I remember correctly, and now it correctly matches most themes (numix being an exception here, thanks for pointing this out).
Would you mind filing an issue about the numix icon, so that we can track it?
Like I say, it's great that you're so happy with it. You seem to have missed that part. I'm just pointing out that you saying his ONLY options are "Switch to Nouveau and take a massive performance hit, or put up with the tearing" is flat out incorrect. The improvement to Marco does not in any way invalidate the options that existed before that change and still work better for many cases, including his.
YOU may not care about the performance, but you are not him. Different people have different priorities, and while your evangelism of the new compositor is helpful to some of them, it's not helpful to people who have already explicitly stated that the prerequisites for getting it to work are not acceptable to them, or that it doesn't work on their hardware. I'm just asking you to keep that in mind, instead of advocating that Marco's compositor is the One True Way no matter what. Okay?
OK. I wasn't sure where to put this. Thanks.
Numix has an icon called "desktop-environment-mate" with the mate logo they can link to "start-here-mate" I think ...
I have a problem with mesa-opencl-icd
I used Mate 19.04 and earlier without a problem, but with 19.10 Beta, it fails.
I use mesa-opencl-icd and the [email protected] project (app) within BOINC to process data on my Radeon/ATI 7750 Card.
The process starts up OK - but I get an error in less than a minute.
The error is reported on https://einsteinathome.org/task/888883349,
I will try to copy and summarize here...

Question: Any ideas?
Go back to 19.04 or 18.04?
T H A N KS in advance,
Looks like one of the libs has bad alignment. And, jep, Phoronix mentions one of the Mesa devs implementing a new scheme for shader loading in May - https://www.phoronix.com/scan.php?page=news_item&px=AMD-Mesa-Real-Runtime-Linker - so the timescale fits.
Blow away the shader cache - I suspect it's stale, and old ones are definitely not going to be compatible (though it's hard to believe Mesa didn't version things properly and handle that case, so I'm not too confident in that guess). Worth a shot though. Or if you're using pre-compiled shaders that you DL'd from somewhere, get new ones.
2 posts were merged into an existing topic: 19.10 - Loading / Saving custom panel layouts is utterly broken
maybe this distribution is really in [lack] of developers, the developers that exist can only do small patches to existing bad coding as no one have time for a code rework
And you'd be correct! Ubuntu MATE (and MATE upstream, they're very much related) is a very small team of volunteers. Some contribute in the evenings, some in the weekends, and others sneak in some code in between meetings at their day job. Bugs, issues, and feature requests pile up much higher than there is time to take care of them. There's also testing, documentation, managing the releases themselves, reviewing all the patches, etc.
Even then, the team still manages to rewrite parts as needed when time allows, and each new release is better than the last, so there's that!
Also keep in mind that developers rarely follow the forum to determine what needs to be fixed. So if you find an issue filed for this already, make sure you add to it as much information as you can to help the developers. If there's no issue filed, then make sure you do it, so that developers are aware.
Lastly, some bugs, even if they seem small from the outside, are incredibly hard to figure out and fix. This might be one of those, for all we know
Hey I had few small issues at first but they went away, though I don't switch layouts often, it often seems to help if you switch to several built in layouts before switching to a custom layout(or a built in layout that is giving you trouble
edit: I just tried switching and mostly it worked flawlessly, until I moved back to my custom layout, then it repeated the brisk menu, besides that it was fine.(I also tried it several more times and while I got it to do it once, after I modified it correctly and saved it under a new name, it worked perfectly even switching from layouts that had the brisk menu) so it seems to be more a problem with custom layouts than built in ones, also in all my testing the panel applets I have had the most trouble with in 19.10 are the brisk menu and mate dock applet, however over all it seems far more solid than previous releases
