Problems with Ubuntu Precise Pangolin

Title: Problems with Ubuntu Precise Pangolin

Version: 3.1.1

OS: Ubuntu 12.04 Precise Pangolin

Java Version: Java 1.7.0_04 Sun

Description of Problem:

Well, recently I went to boot from my Linux partition, which was a fresh install of Ubuntu. I got it all nice and working, so I download Minecraft and Tekkit/Technic Launchers.

My first problem is this:

Run launcher by terminal/desktop icon, log in, like insta-second of updating MC/etc, and then a white/back screen depending on tekkit/minecraft

Tekkit is a white screen, Normal MC is a black screen.

Now, I found out that MC/Tekkit use an older version of LWJGL, which causes compadability issues with specificly Linux users.

I manually updated my LWJGL to version 2.8.4 and it fixed the problems immediantly. I also removed OpenJDK java and use Sun's java now.

Everything works fine, then I goto bed.

The next morning (earlier from now) I log into a Tekkit server, noodle around a bit, and suddenly I get a Dirt Screen, and it doesn't go away. Im left to terminate all java processes, and restart Tekkit. I now cannot login to that server anymore. I try to login and it gives me a dirt screen for like a second, and then a white screen. No errors or messages.

Any suggestions?

I Am On Ubuntu and can't use tekkit or minecraft

as for the server it could be a bug in the server itself? does it work on other servers?

I am using 64-bit Ubuntu 12.04 with openjdk-6 and have no problems running any version of minecraft (including snapshots of upcoming versions), and technic launcher works fine for tekkit 3.1.2.

I have been using openjdk-6 to run minecraft successfully since minecraft 1.8 beta (in Ubuntu 10.10 and 11.10). Since there is a sticky movement key problem with default lwjgl 2.4.2, I have always used lwjgl 2.6 for minecraft. I tried setting latestLWJGL: true in .techniclauncher/launcher.properties for tekkit, but for some reason that has reverted to false. Oh well, at least I know that if a key sticks, I have to press the key in the direction I am moving to clear it (not the opposite direction).

For desktop or unity launcher, you need to either need to launch a script in a terminal, or wrap a command line and parameters in single quotes launched by a shell (like sh -c 'java -Xmx2G -Xms1G -cp ~/MC-client/minecraft.jar net.minecraft.LauncherFrame'). But because the technic launcher backgrounds itself, I have not gotten a launcher to work for it, so I open a terminal and launch it with a script.

Not sure why people say you need real Java (which requires proper installation and is no longer in repositories), when openjdk-6 has always worked fine for me (haven't tried openjdk-7).
