hello...first time with centOS...10 + years (off and on) with linux
some applications are not opening...i get the 'bouncing' icon when i select an application...then the icon disappears...nothing 'opened'...
...using a thinkpad t500...any ideas?

Hello and welcome to LQ.

Should work. (not helpful huh?)

Might be that your ram is too low or slow swap or defective install.

I assume that you mean that default applications are not working correct?

Try launching the application from a terminal, then paste the output that appears in the terminal here, in code tags.

I use Red Hat on servers, but in my experience it's been fairly unpleasant on the desktop; just not enough everyday-user packages. lxqt is in EPEL, for instance, but lxmusic is not.

However, it being Linux, of course it can be done, mostly by borrowing from the hard work of the Fedora devs:

1. Install RPM Development Tools:

Code:

$ sudo yum grouplist -v 
$ sudo yum groupinstall fedora-packager

2. Grab the source RPM for lxmusic from Fedora

3. And then build it for your system:

Code:

$ rpmbuild --rebuild lxmusic-0.4.7-1.fc24.src.rpm

4. Install with yum...

Code:

$ sudo yum install rpmbuild/RPMS/`uname -m`/lxmusic*centos*rpm

thank you notKlaatu

"Try launching the application from a terminal, then paste the output that appears in the terminal here, in code tags." what terminal command would i use to launch BlueDevil ? and what are code tags?

when i ran: sudo yum groupinstall fedora-packager
i got this:

Warning: group fedora-packager does not exist.

interestingly there were 2 links originally in your reply that pointed to facebook...however the links have disappeared...one link was "Development Tools" the other was in the first line though i can't remember which words exactly...weird...
