Hi,
Sorry if this isn’t the right place for this question. I did some searching and didn’t come up with anything. I’m using openSuse 12.3 now, and the KDE performance seems a little bit slow. I was getting 45-55 fps in Minecraft on Kubuntu 13.04 with the graphics all the way up last week. On openSuse, I’m getting 25-30 with the graphics on medium settings. Is there anything I can do to speed things up? In both settings, I had the desktop effects disabled.

Might be useful if you told us a little bit about your hardware and
configuration.

Right, it’s an HP laptop(ultrabook) with an i5 3317u and Intel HD4000 graphics and 16gb of RAM. It’s running 64 bit openSuse with the KDE desktop. It has an AMD 7670m GPU that I gave up on long ago and have disabled all the time now. The desktop runs fine. It’s only in gaming that I notice it’s slower than Kubuntu was. Is there any other information that would be helpful? Its a plain install. Nothing out of the ordinary.

Is your 12.3 installation 32-bit or 64-bit?

It’s 64-bit.

On Kubuntu, were you running the Oracle JVM or OpenJDK? (The latter is
what’s included with openSUSE, but you can install the Oracle JVM if you
download it from Oracle - their licensing changed so it can’t be
distributed with the distribution any more, so I understand)

I was running the openJDK 7 on Kubuntu, which is also what I’m using on openSuse. I used the same command to run the game in both cases too:
java -Xmx2048M -Xms2048M -jar minecraft.jar
Also, thanks for taking the time to help me figure this out. I appreciate it.
BTW am NON-Technical 
Followed advice from earlier this games group posts, expect a quick search minecraft to show.
Fixed my problems with this post:
Dated: 10-May-2013, 01:25
Author: rrimc69
Subject: Minecraft 1.5.2 with .jar mods including fix for black screen
since subscribed in openSUSE 12.3 GNOME am using terminal and command: java -Xmx1024M -Xms512M -cp minecraft.jar net.minecraft.LauncherFrame
BTW not using browser, opens another terminal with color which young one likes more than browser earlier, currently busy on other machine
My notes:
minecraft, (latest) LWJGL, appears work OK
seems both minecraft and LWJGL updating regularly,
whilst still not sure which jar files used, those in ~/.minecraft or one of several in ~/bin
.
Thanks for replying. My issue is not a black screen. It’s slow performance in-game. I may look into optifine as a solution, but I was really hoping for some configuration options that might help my whole system if possible.

No problem - I also occasionaly play Minecraft myself (though it’s been a
while).
Since you’re using the Intel driver, it might be interesting to compare
versions between the two distributions and see if maybe the Kubuntu
install is running something newer (or older, for that matter).

I’ve been looking for the Kubuntu version number on the xf86-video-intel package, and as far as I can tell, it’s 2.21.6-0. I have 2.20.19-2.1.1 installed in openSuse. I’ll see if I can update that. I also updated the kernel to 3.9.7-1, and it didn’t have any effect on Minecraft (didn’t really expect it to).
Version 2.21.10 is in the XOrg:X11 repo.
But you would have to upgrade your whole X stack to the versions in that repo.
Do the following:
sudo zypper ar http://download.opensuse.org/repositories/X11:/XOrg/openSUSE_12.3/ xorg
sudo zypper dup --from xorg
After a reboot you should be using the latest versions of X and the intel driver…
If you get some dependency errors, please post them so I can advise the best action to take.
Ahh, I already did the upgrade, and you’re right. I had to upgrade X while I was at it. So far no issues, and Minecraft is getting around 40-55 fps depending on what’s going on around me. It seems to have helped!
Great! Nice to hear…
Thanks for sharing a great post. I appreciate your thinking
