Hello!

I have run into a problem recently where when I login to minecraftin Fedora 17 I get a blank screen. Basically, I can run the client and login but all I get after login is a blank screen.

My java version is:

[[email protected] ~]$ rpm -qa | grep java
tzdata-java-2012j-1.fc17.noarch
java-1.7.0-openjdk-1.7.0.9-2.3.3.fc17.1.x86_64
java-1.7.0-openjdk-1.7.0.9-2.3.3.fc17.1.i686

And to run it I have run "java -Xmx1024M -Xms512M -cp minecraft.jar net.minecraft.LauncherFrame" as copied and pasted from minecraft.net. I have tried to change 1024 and 512 in this command to be the same (ie 512 chagned to 1024 and vice versa) I have also tried redownloading the .jar as well as getting rid of ~/.mincraft and letting the game rebuild it. I have also tried running this as different users and everytime I get the same error:

[[email protected] jesse]# java -Xmx1024M -Xms512M -cp minecraft.jar net.minecraft.LauncherFrame

I know Linux Very well but I do not know what could be causing this. Any ideas? [Note: I prefer to use openjdk as opposed to sun's crap. I /always/ have issues installing Sun's jdk. I've been able to run minecraft with open jdk for years so I don't think that is it...]

I can't think of any other logs, errors or data to pass along but if there is something I can pass along that would be helpful let me know.

This is a bit of a long-shot, but you can try turning off OpenGL. To so this outside of Minecraft, the path (at least on mac) is:

Home
Application Support
Minecraft
options.txt

Change AdvancedOpenGl from true to false.

Also on Linux, I believe that you need to have different LWJGL files than Minecraft ships with.

Thanks guys. What are the LWJGL files? I assume they have something to do with OpenGL. I'll look it up when I have a second. Thanks guys.

[edit: s/"look this up"/"try it and get back to you" ]

You guys are great! That was it. lwjgl files must have gotten out of date at some point. Thanks
