Adding my user to the video group and rebooting solved the problem for me.
glxgears now also works.

I can now launch both OSCARs, from deb (repo) and built in my system.

Hope this simple solution works for others as well.

OK! I just learned something new.   In Linux the default graphics engine is OpenGL and will not be listed in OSCAR's configuration file, unless you change its setting.

To set the graphics engine to the Software engine in Linux, edit the  .config/OSCAR-Team/OSCAR.conf file.
Add the following lines to the beginning of the file:
[General]
GFXEngine=2


Your OSCAR.conf file should now look something like this:

Code:

[General]
GFXEngine=2

[MainWindow]
geometry=@ByteArray(\x1\xd9\xd0\xcb\0\x3\0\0\0\0\0\0\0\0\0\0\0\0\a\x7f\0\0\x4\xf\0\0\x1\xb7\0\0\0\x8f\0\0\x5\xb5\0\0\x3\xb2\0\0\0\0\x2\0\0\0\a\x80\0\0\0\0\0\0\0\x1b\0\0\a\x7f\0\0\x4\xe)

[Settings]
AppData="OSCAR's Data folder location"
Language=en_US

Parameter values:
0 - sets the graphics engine to OpenGL (the default).
2 - sets the graphics engine to "Software"

You will need to restart OSCAR if it is running when you make this change for it to take effect.

Linux users use to write :
~/.config/OSCAR-Team/OSCAR.conf
~ is a link to the home folder of the current user.

You can also write :
- /home/$USER/.config/OSCAR-Team/OSCAR.conf
or
/$HOME/.config/OSCAR-Team/OSCAR.conf file


.config/OSCAR-Team/OSCAR.conf works only if your are in your home directory.
You can change to your home directory with
cd (without argument) [maybe not on all distribution]
cd $HOME
cd /home/$USER

Thank you for the clarification. After thinking about your post, would you please provide an instance where you would be in someone else's account to use OSCAR?

Interesting. I never thought of the video group. It seems that Debian makes every user a member by default.

Too late now, but I should clarify the shift key startup. You have to hold down the shift key and then start OSCAR while the shift key is held down.

Thanks for reporting back.

This is a question not specific to this thread, and I would welcome removing it shortly...
Does the framework of this forum allow for, when answering to a given post, hyperlinking to that post?
Something like reddit, or others.
Otherwise, posts keep crossing each other, and it gets difficult to follow the tree of conversations within a thread.

EDIT
I now see in this post that it is possible with "Reply with quote". It's just that people don't use it, even if it is quite useful.
Next step: learning how to delete this post.

@sancho
People generally don't use Reply with Quote unless it's necessary.  It tends to clog up the thread and make things harder to follow.
If you need to use it to maintain context that's fine.  Just snip out the stuff you don't need.

Here is a thread on the matter: http://www.apneaboard.com/forums/Thread-...with+quote
