Allocating 2GB will be running into swap so might actually reduce performance, but I'll give it a try. EDIT: Nope, still just shows white screen and processor sits idle; clearly not allocating memory and loading things like Minecraft does when it launches successfully....

Oh, sorry. I read "Check" as 'review'. I'm not from the US, and we say `ticked` instead of checked where I am Still no luck... Increase PermGen Size is ticked/checked, and I can only set the RAM size to 512MB...

Just to be clear, you're implying I should have Increase PermGen Size ticked?

I've got the launcher working, Tekkit's all downloaded, but when it tries to start the Minecraft window, I get FML doing its thing, then it disappears and leaves me with a blank, white Minecraft/Tekkit window - the one that should be saying "Mojang" or whatever. I'm running Linux (that shouldn't be introducing the problem though). What I think might be the problem is that when I run Vanilla Minecraft, I have to run its launcher using java -Xmx800m -jar launcher.jar Otherwise it gives similar symptoms to what's happening to Tekkit. I suppose Tekkit or FML isn't running minecraft in the above way or something, causing it to not work? Any suggestions/help/anything?
