Ubuntu – Minecraft Fullscreen not working

fullscreenjavaminecraft

I upgraded to Quantal recently, and Minecraft seems to not want to run in fullscreen. When I go to fullscreen it, the screen will go black for a second, as if it was about to go fullscreen normally, but then it just restores back into its window. So far I have tried:

using different JREs (I've tried openjdk 6 and 7, as well as oracle7). Oracle's jre wouldn't even run Minecraft (I just got a black screen after logging in)
switching graphics drivers (tried nvidia-current, nvidia-current-updates, and xserver-xorg-video-nouveau)
updating minecraft bin files
updating lwjgl libraries separately from the lwjgl site

None of this seemed to work at all.

I am running Minecraft with the command java -Xmx1024M -Xms512M -cp minecraft.jar net.minecraft.LauncherFrame

Graphics card is GeForce 9500 GS/PCIe/SSE2.

Everything was working fine a few days ago when I was on 12.04.

This happens to me too. But, at random, when I press F11, it goes full screen. So I keep pressing F11 until it stays full screen. Sometimes it takes up to 10 tries.

Try using Magic Launcher

For starters, there is a big chance those are two different issues

Your friend not connecting might be an incorrect port forward. Google around for a site that will do a port check on your IP (there are tons).

Your error is game client/java related. Verify that you have the correct java version installed (check the one your friend has, if it works for him) and install it like so: How can I install Sun/Oracle's proprietary Java JDK 6/7/8 or JRE?

If that doesn't work try removing the mods? I haven't personally played minecraft (downvotes incoming i guess?) but that's one of the first things i'd try.

Ubuntu – What do I do when Minecraft in fullscreen loses focus

wmctrl tool provides command line access to window manager (not installed by default, the package is named wmctrl). The -a flag permits a user to Activate the window by switching to its desktop and raising it. (Note that you can find the window name with -f option)

$ wmctrl -l
0x01600007 -1 hostname Desktop
0x04200002  0 hostname mouse - What do I do when Minecraft in fullscreen loses focus? - Ask Ubuntu - Google Chrome
0x03200007  0 hostname Terminal
0x03e00015  0 hostname Minecraft 1.10.2
$ wmctrl -a "Minecraft 1.10"

Thus a complete recipe could be

Switch to virtual console Ctrl+Alt+F1
Login
DISPLAY=:0 wmctrl -a "Minecraft 1.10"
Switch to x server console Ctrl+Alt+F7 (or F8)

See this other answer for more details on wmctrl.
