Have you mesa installed? Go the updatedb && locate libGL* route(as root). You NEED mesa for graphics.

Again, please, if you're getting the same error
Code:
sudo updatedb
sudo locate libGL*
Then grep them as described in post #2

here is the output with an extra command...

Code:
main@dell-xps-17:~$ glxinfo | grep "OpenGL version"
OpenGL version string: 3.0 Mesa 18.0.5
main@dell-xps-17:~$ sudo updatedb
[sudo] password for main: 
main@dell-xps-17:~$ sudo locate libGL*
[sudo] password for main:

OK. You have Mesa-18.05, which is recent but _something_ is missing the symbol "glCheckFramebufferStatus" and compton appears to be puking over it. Would you agree, or is it working now?

If you can't find the Mesa libGL* libraries, it's possible compton can't find them either. What you posted in your last post makes no sense to me. With Mesa-18.05 installed, libGL should be available, and yet mesa appears to be happy without them :-o. The only thing I imagine is that compton was written with Mesa in mind, and there's a different setup in Ubuntu. You will need to ask someone who knows ubuntu. The nearest thing I have is Mint-19. This uses debian & ubuntu debs, but departs from them in graphics Here's the transaction in Mint
Code:
glxinfo |grep "OpenGL version"
OpenGL version string: 2.1 Chromium 1.9
dec@Mint19-VBox:/usr/lib$ sudo grep -r glCheckFrameBufferStatus *
dec@Mint19-VBox:/usr/lib$ sudo grep -r glCheckFrameBufferStatus /lib/*
dec@Mint19-VBox:/usr/lib$ sudo grep -r glCheckFrameBufferStatus /usr/local/lib/*
bash-4.4$
Either way, you don't have that symbol "glCheckFramebufferStatus" that Mesa supplies and compton wants. Framebuffer is old technology, and you don't want it; So I'm not surprised if modern graphics setups (Wayland & suchlike) weren't backwards compatible. Try this final test
Code:
ldd /path/to/compton |grep found
and if that scores hits, that's your problem. You should have no output. I'd search on Ubuntu's website, or this one. Someone is bound to have hit this problem before.

I'm guessing this has something to do with Bodhi, as compton works as expected in straight Ubuntu. Since the Bodhi forums are defunct, this is the place to find other Bodhi users. That is why I posted the question here. To see if other Bodhi users have any issues with compton. Then I can go from there.

I will probably convert an Ubuntu install to Bodhi, and see if it effects compton next. I'm wondering if there is a package missing in Bodhi.

As I posted earlier. I get the same results from the command above in both Bodhi and Ubuntu installs, yet compton works in the Ubuntu install.

But thanks for the help! I'll google and see if I can find the LibGL* Libraries in Ubuntu.

now that I've seen this compton thing you're asking about, and know little about, as I just run what is installed, and have not messed with compton or anything like it in years. to give shadows and such. this is what I've found.

something called compiz-reloaded
http://www.cupoflinux.com/SBB/index.php/topic,4408.html
https://github.com/compiz-reloaded

might want to take a look at that too while you're at it.

You're welcome. The things that will narrow it down is not searching for libGL*, imho although I started there. The most logical assumption is that some package was compiled against Mesa, and uses that 'glCheckFramebufferStatus' symbol. libGL* isn't on your system. To find what needs it, you can try grepping for 'glCheckFramebufferStatus', or using 'ldd /path/to/executable |grep found' and if something wants libGL*, that's your problem isolated.

From the Ubuntu repo, using synaptic or CL apt-get.

Did you ever get Compton to work?

Recently installed BL5 resulting in video playback screen tearing problems that I have not been able to fix. I can't seem to get Compton to work on BL5.

i got curious about tracking down the source of my fix so i thought i would include this just in case it might help someone else:

Quote:
So If you’re having trouble with streaming quality in Firefox try this:

In a blank location bar type: “about:config”. You’ll get a warning screen (charmingly about dragons!) and when you proceed a very long list of variables.

Scroll down to “layers.acceleration.force-enabled” and set the value to “true”.

I solve the tearing issue in FF or GC with compton and it helps

Stefan

EDIT:
@naughtoloose: This is my /.config/compton.conf file I use with compton. Maybe it will help. Also, I have compton enabled after boot in startup applications

@cordx, yes Netflix in FF is part of the problem but also all other video playback options like VLC (none of the available rendering settings help) and graph intensive spreadsheets etc.
every little bit helps though

@the waiter, that helped a lot, not perfect but definitely a great improvement. At least now I see Compton is actually working whereas before there was no noticeable difference between running Compton and nothing.


Thanks a lot both of you
