I don't know about that. I only know I've never had to compile my own mesa drivers. So, I thought you might be needing them for something specific. I was only curious to know why you needed the mesa drivers so urgently.

Code:
~# ls /var/log/packages/*mesa*
/var/log/packages/mesa-17.2.7-arm-1
This isn't what you're looking for is it?

Try doing 'ls /var/log/packages/*mesa*' on your system. If you don't have it...

Code:
~# wget ftp://ftp.arm.slackware.com/slackwarearm/slackwarearm-current/slackware/x/mesa-17.3.1-arm-1.txz
~# installpkg mesa-17.3.1-arm-1.txz
Edit: I don't use X or a desktop environment for anything but testing. I'm really the wrong guy to ask questions about it, and all related things.

Quote:
Package mesa-17.3.1-arm-1.txz:
PACKAGE DESCRIPTION:
# mesa (a 3-D graphics library)
#
# Mesa is a 3-D graphics library with an API very similar to that of
# another well-known 3-D graphics library. :-) The Mesa libraries are
# used by X to provide both software and hardware accelerated graphics.
#
# Mesa was written by Brian Paul.

MESA is also a library of 3D graphics primitives - SW implementation of OpenGL(&co) that Xorg uses for specific 3D application. On Raspberry MESA needs the VideoCore device driver (vc4) in order to use the HW accelerated 3D routines from within the GPU:
https://en.wikipedia.org/wiki/Mesa_(...Device_drivers
https://en.wikipedia.org/wiki/VideoCore
https://github.com/anholt/mesa/wiki/VC4

In my previous post I've instructed you on how to enable that vc4 driver at boot time and confirmed (I wasn't aware of that) that the MESA libs/driver is already compiled to make use of the vc4 driver in Slackware ARM current. Following the steps from that post will get you what you asked in your OP, without recompiling MESA on your own:

yes i did a
Quote:
glxinfo | grep -i opengl
And confirmed that it was using Opengl acceleration.

But what about the driver in X?
I remember in FreeBSD with my NVIDIA card that the script made an xorg.conf file that said "Driver nvidia".
What i mean is: is it the same in linux?

Mesa is your X driver now, have a lecture on these links:
