Compton

Randy4bodhi · 09-22-2018, 09:02 AM

Anyone else get this error when running compton?

Code:

compton: symbol lookup error: compton: undefined symbol: glCheckFramebufferStatus

business_kid · 09-22-2018, 02:29 PM

Change to your library directory (You don't tell us your distro) & run

Try

Code:

grep glCheckFramebufferStatus  libGL*

What do you get?
What's your mesa version? You masy need to update. BTW, what is compton?

compton is an area in southern LA county. it is also a windows manager i guess you could say. it is supposed to be great for an issues re: screen tearing. windows compositor i guess is the term. you got me on that one randy....

I am running Ubuntu 18.04 based Bodhi Linux 5. Compton is a compositor.

Are we talking /lib as the library directory?

Randy4bodhi · 09-22-2018, 09:30 PM

I ran it in the /lib directory and it says libgl package is not installed. Also I should mention that I don't get this error on my ubuntu 18.04 openbox install.

I may have posted this already, but have to mention when it when I see compton cuz so far nobody else has even said they have a different experience.

In my experience, on three computers, if I have Compton running, when I resume from idle, my shelf clock is inaccurate and doesn't update correctly.

I also tried xcompmgr (which is already installed) and have the same result. The only reason I even installed compton was to make conky transparent.

No errors that I recall and I even tried to run it from command line to double-check but no longer have it installed. xcompmgr runs w/o error.

this does not appear to be the answer to what business_kid asked.
please show us commands issued & their full output.
use code tgas for code, here on LQ.

doesn't moksha (enlightenment) already have a compositor? why would you need compton?
how did you install compton (do NOT answer this question before you answered the 2 previous ones)?

There are 3 questions and 1 statement that asks for more info. I answered 3 out of the 4. Plus asked for clarification.

Statement: You didn't mention which distro you where running. I am running ubuntu 18.04 on which Bodhi Linux 5 is built ( hence I posted this in the Bodhi Linux forum section).

1. what is the output of the command...

Code:

grep glCheckFramebufferStatus  libGL*

Answer: I ran it in the /lib directory and it says libgl package is not installed. Also I should mention that I don't get this error on my ubuntu 18.04 openbox install.

2. What is your Mesa version. Did not answer this as it is the same as on my other install.

3 What is compton? as I answered in a previous post ... it is a compositor.

I would show full output but it was just a short simple reply. The same reply I get when I run it in my ubuntu openbox install.
(actually it says file not found) my mistake.

(I am still not sure i'm running the command in the correct directory).

The developers of Moksha removed the built in compositor because it was too buggy to fix, and caused a lot of problems.

I use compton to get proper transperancy, and to reduce screen tearing.

randy - so what does Bodhi use if any? just curious. I never had any issues and i know so little so i was wondering. thanks.

business_kid · 09-23-2018, 10:49 AM

I'm pretty sure it should be /usr/lib. Try this

Code:

ls -l /usr/lib/libGL*

You should see 4 or 5 libraries, and a rake of symlinks. Provided you do, run the check in post #2. Otherwise, run

Code:

updatedb
locate libGL.so*

and that should find it for you. Run the check there. I get this

Code:

bash-4.4$ cd /usr/lib64                    
bash-4.4$ grep glCheckFramebufferStatus libGL*
Binary file libGL.so matches
Binary file libGL.so.1 matches
Binary file libGL.so.1.2.0 matches
Binary file libGLESv2.so matches
Binary file libGLESv2.so.2 matches
Binary file libGLESv2.so.2.0.0 matches
Binary file libGLEW.so matches
Binary file libGLEW.so.2.1 matches
Binary file libGLEW.so.2.1.0 matches

When did you update the system last? (I'm on Slackware64, btw.)

Bodhi currently has no compositing. So in the old forums, it was recommended to install compton.

You may only notice screen tearing while watching video. Compton if configured properly, can eliminate it.

Norm,

It also provides transparency for things like conky. If you run conky in bodhi and use any transparency in your configuration, without a compositor, you will probably end up with an ugly black box around it. With compton, it blends to the desktop better, because it provides true transparency. It also provides special effects like shadows, and window transparency. Mainly for aesthetics.

For instance look closely at this screenshot.

You can see the word "Forecast" through the title bar of firefox. and if you look at the edge of pcmanfm and conky, you can see a grey shadow. That is some of what a compositor does.

Hope this helps explain it a little.

Thanks so much - i guess i never installed it on 4 or 4.5 and nothing on 5 and so far all seems to work so unless i run into something i will leave it as is. when i saw your post i had no clue what you meant and had to do a quick search about the concept of compton. weird i can get along for so long with no use of it and no noticeable issues, so far at least.

I updated both systems yesterday. They do have different kernels, but I'm not sure that would make a difference.may just for the heck of it, I'll match them up.

This is what I get. Mostly nothing. But I get the same thing on a working ubuntu openbox install also.

Code:

main@dell-xps-17:~$ cd /usr/lib
main@dell-xps-17:/usr/lib$ ls -l /usr/lib/libGL*
ls: cannot access '/usr/lib/libGL*': No such file or directory

Code:

main@dell-xps-17:/usr/lib$ cd /lib
main@dell-xps-17:/lib$ ls -l /usr/lib/libGL*
ls: cannot access '/usr/lib/libGL*': No such file or directory

Code:

main@dell-xps-17:~$ updatedb
updatedb: can not open a temporary file for `/var/lib/mlocate/mlocate.db'
main@dell-xps-17:~$ locate libGL.so*
main@dell-xps-17:~$ updatedb && locate libGL.so*
updatedb: can not open a temporary file for `/var/lib/mlocate/mlocate.db'
main@dell-xps-17:~$ sudo updatedb && locate libGL.so*
main@dell-xps-17:~$

Yea mostly it's for asthetics. But If I don't use it, I get a lot of video tearing which is rough on the eyes. And as you know I'm an old fart!

But your right don't fix it, if it aint broke.
