CanVox mentioned here: http://forums.technicpack.net/threads/upside-down.45469/ that it is LWJGL's fault, and they have a beta fix. I would love to see it!

Updating to Java 7 didn't work for me. Same method.

I've worked out what it is! It means you have an activated Black Hole Band in your inventory or in an Alchemy Bag you're carrying. It's activated if it's purple.

That sounds like a different issue; with the launcher not Tekkit itself. I can only recommend searching these forums for someone else with the same problem. Find the logs folder in your techniclauncher folder and open the file with _0 at the end. At the bottom (it's often a pretty massive file) should be your most recent launch, you can see by timestamp. Look for any errors, and maybe post as a bug report with the log file (you only need the part after the last "---------" in the file). You could also PM me the last part of the log file and I'll try and pinpoint the problem.

If you don't have Java 7 (or 1.7, they're the same), then install it. If you're replying to this thread, I'm assuming you're running Ubuntu too, so make sure you install openjdk-7-jre using the terminal (apt-get), synaptic or the software centre. If you don't know how to do this, google it up and you'll find something. If you do have Java 7, try clearing the cache from the launcher options window. You will need to replace your LWJGL libraries again after this. Make sure you replace all the necessary files, see http://www.minecraftwiki.net/wiki/Tutorials/Update_LWJGL for detailed instructions that I used. Failing this, try renaming the tekkit folder in ~/.techniclauncher so it gets replaced entirely, and repeat LWJGL replacement. Good luck!

Fixed by manually downloading the latest LWJGL libraries from their website, and replacing the LWJGL files in tekkit/bin and tekkit/bin/natives.

I have the same problem on Ubuntu 12.04 64bit machine with OpenJDK 7.

Launcher Version: 1.0.1.3 Operating System: Ubuntu 12.04 64bit Java Version: 1.7_05 Antivirus Program: Description of Problem: When I sign in to the Technic Launcher and select my mod of choice (usually Tekkit, but bug was present for others as well), I click "Log in". Immediately a new window appears with the title "Tekkit" (or whatever modpack I am using), and the launcher window disappears after a few seconds. However, the game window stays white, and never reaches the Mojang screen. I have tried redownloading the Technic launcher and clearing the cache from the launcher (therefore redownloading mod files). I also tried using Oracle Java 7 rather than OpenJDK (default for Ubuntu), but there was no effect. I don't have this problem on my mac, which is also running this version of the Technic launcher.

When I chose to keep all my world directories in a subdirectory, rather than in the main server dir, Railcraft gave an error, showing it was still looking in the root of the server. This is not a clean server, but it should still work. Here is the error from the server log: 17:47:06 [sEVERE] java.lang.RuntimeException: /home/.manage/bukkit/tekkit-server/middle-earth is not a directoy. 17:47:06 [sEVERE] at railcraft.Railcraft.getWorldSaveDir(Railcraft.java:69) 17:47:06 [sEVERE] at railcraft.common.RailcraftSaveData.getData(RailcraftSaveData.java:28) 17:47:06 [sEVERE] at railcraft.common.ChunkManager.loadAnchors(ChunkManager.java:322) 17:47:06 [sEVERE] at railcraft.common.ChunkManager.updateTick(ChunkManager.java:424) 17:47:06 [sEVERE] at net.minecraft.server.mod_Railcraft.onTickInGame(mod_Railcraft.java:64) 17:47:06 [sEVERE] at cpw.mods.fml.server.ModLoaderModContainer.tickStart(ModLoaderModContainer.java:285) 17:47:06 [sEVERE] at cpw.mods.fml.common.FMLCommonHandler.gameTickStart(FMLCommonHandler.java:77) 17:47:06 [sEVERE] at cpw.mods.fml.server.FMLBukkitHandler.onPreTick(FMLBukkitHandler.java:129) 17:47:06 [sEVERE] at net.minecraft.server.MinecraftServer.w(MinecraftServer.java:494) 17:47:06 [sEVERE] at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:453) 17:47:06 [sEVERE] at net.minecraft.server.ThreadServerApplication.run(SourceFile:492) 17:47:06 [sEVERE] Unexpected exception java.lang.RuntimeException: /home/.manage/bukkit/tekkit-server/middle-earth is not a directoy. at railcraft.Railcraft.getWorldSaveDir(Railcraft.java:69) at railcraft.common.RailcraftSaveData.getData(RailcraftSaveData.java:28) at railcraft.common.ChunkManager.loadAnchors(ChunkManager.java:322) at railcraft.common.ChunkManager.updateTick(ChunkManager.java:424) at net.minecraft.server.mod_Railcraft.onTickInGame(mod_Railcraft.java:64) at cpw.mods.fml.server.ModLoaderModContainer.tickStart(ModLoaderModContainer.java:285) at cpw.mods.fml.common.FMLCommonHandler.gameTickStart(FMLCommonHandler.java:77) at cpw.mods.fml.server.FMLBukkitHandler.onPreTick(FMLBukkitHandler.java:129) at net.minecraft.server.MinecraftServer.w(MinecraftServer.java:494) at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:453) at net.minecraft.server.ThreadServerApplication.run(SourceFile:492) Any ideas how I could fix this, or anyone with a similar problem? Otherwise I'll go and file a bug with the Railcraft devs.
