slackware current 32bit recent upgrade killed my son's ability to play minecraft

Dear Slackers,

The recent upgrade bump to 3.9.5 had some side effects for me:
minecraft will not run; I use AlienBob's minecraft package with either
a) the java slackbuild in /extra
b) the new openjre packages from Alienbob (7b40)

but to no avail ; I get a fatal error

Before the bump on 3.8.13 I had no problems whatsoever...

Does anyone have a clue as to what I could change to rectify the problem?

I run on Kde 4.10.4 with either OpenGL and Native for compositing and Qt graphics or (Xrender and Raster)

Thanks in advance

As far as i know minecraft needs/depends on the orginal (from java.
i have jdk installed no problem. The latest version as of is 7b21, you find jdk 7b21 also on slackbuilds.

Give that a try, you also can try updateing minecrafts lwjgl to a newer version.

I did not have that error, in fact I can play minecraft just fine using openjre 7u40 and my own minecraft package, but only after I updated the bundled Lightweight Java Game Library (lwjgl):

It is a known issue with the bundled lwjgl library (which gets downloaded as part of the initial update of minecraft).

You can manually update the lwjgl library from the one that minecraft bundles to version 2.9, which fixed my issue of a black minecraft screen after logging on.
Download the archive with the binaries, and copy the new lwjgl files into the .minecraft folder in your home directory, overwriting what's there:
$ wget
$ unzip
$ cd lwjgl-2.9.0/
$ cp jar/* ~/.minecraft/bin/
$ cp native/linux/* ~/.minecraft/bin/natives/

Problem is now solved. (But not by the suggested solutions.)

Mine craft works with both the open versions from AlienBob as well with the closed versions of java (I use now openjre).
The black screen phenomenon described by AlienBob is indeed fixed with an upgrade with lwjgl. (I already knew about this).

What fixed it was:
I installed the propriatary AMD driver but I opted for creating a slackware package (as is well described in the slackware documentation project).
After installing, minecraft works but the texture is now looking awful.
However after upgrading mesa files are messed up (they are in the wrong place it seems). To fix that and restoring the normal textures do the following:

make a symlink with
target /usr/lib/fglrx/ and link name thus
ln -s /usr/lib/fglrx/ /usr/lib/
Now it works properly.

This was solved by

I think the ATI SlackBuild needs updating, but for the meanwhile, you can move the mesa to and make a symlink to fglrx/ as
Why it didn't work with a non proprietary driver is still a mystery to me.

Thanks AlienBob and Stuferu for your kind advice.
Thanks Zakame for the proper solution in my case.
