Minecraft cause X to run at 100%

Cif · 2012-07-13 21:56:36

When I start Minecraft, after 20/30s cause X to run at 100% of one core and desktop is not usable anymore. If I'm lucky I can quit the game or I have to ctrl + alt + f1 and kill Java. Once happens, X refresh monitor every 2-4 seconds, input are still fine bit is not usable anymore. I have nVidia driver with two monitor, AMD Phenom X4, 8GB RAM. I tried with: openjava6, openjava7, jre6, linux-ck with latest driver, linux with latest driver, linux with 295 driver, linux-lts with latest. Nothing works, I can't play Minecraft

Odd. I have no trouble playing it with the latest JDK/JRE, etc., also on a dual monitor setup. Are you running the release version of Minecraft or a snapshot? Also, are you using a DE like Gnome or KDE? What graphics card do you have in that machine? Do other OpenGL apps cause similar grief?

I'm running the AUR version, so the last 1.2.5, using XFCE, with a nVidia 8300 integrated. I can play WoW in wine without problems...

Does it freeze when you're sitting at the menu or only when you're playing the game?

Looking back at your original post, it's perplexing to me that it's causing X to peak at 100% CPU rather than Java.

Try running Minecraft from a console by itself (this assumes you're running aur/minecraft):

java  -Xmx1024M -Xms1024M -cp /usr/share/minecraft/minecraft.jar net.minecraft.LauncherFrame

And then examine that console for output when the freeze occurs.

I tried that command but nothing strange show up

So is this happening in the game menu or when you actually create a world? Have you also tried changing any of the video options from the menu?

It seems this might be a bug with Minecraft rather than anything specific to your configuration.

Cif · 2012-07-18 23:08:24

I t happens during the game, after 20-30 seconds. If I left the game in the main menu seems ok, the problem do not appear. I changed all the options, I removed all effects without success.

This is beginning to sound like it might be a bug in Minecraft, and therefore far beyond my ability to fix. Perhaps there's someone else here who may have some additional ideas.

Failing that, it may be worth posting on the Minecraft forums. A quick Google search turns up a similar issue from over a year ago but without any clear resolution. Surely someone else has had similar issues, and it seems to me that you've tried everything.

One additional thing that may be worth trying is to grab a copy of lwjgl either from the AUR or from SourceForge, move the existing Minecraft copies (usually under the Minecraft "natives" directory) somewhere safe, and then use the ones you've downloaded in their place. There are a few versions of them on SF, but the 2.7.x ones were somewhat unusable if memory serves. If you've already tried this, disregard.

I reinstalled Arch, but I found out the same problem using nVidia driver. Using nouveau I have no issue
