Debian :: Why To Have To Use Root To Play Minecraft
Jan 10, 2016
I can run Minecraft if I log in to su but I have a user to whom I do not wish to give su permission. If I try to run Minecraft from the terminal without signing into su first, I get a lot of error messages that I do not understand. I think it might have something to do with having to give the user permission to run java but I am not sure.
Here is the output:

My issue is fairly simple, I just want to play Minecraft, which requires Java. I tried installing it with the Java website instructions and then with a sudo apt-get install command. I believe the problem is simply a plugin issue with Firefox. Anyway, the distro is Ubuntu 10.04 if that helps.
Now the reason im thinking about switching from windows xp to Ubuntu because i have more ram than it will accept I have 4 gigs and its only using 2 I also know the reason this is (because its 32 bit not 64)
Code: Is it possible to play Rift on Ubunutu? Is it possible to play Minecraft on Ubuntu? Can i run Google Chrome on Ubuntu What is the ram limit for Ubuntu? Can i run Rocket Dock on Ubuntu or does Ubuntu have a similiar built in feature. And is there a possibilty of Rift and Minecraft running worse on ubuntu than they do on my crappy xp os? How do you install ubuntu without a disc? How do i duel boot windows xp x32 and Ubuntu?
I recently loaded up my old powermac g3 with debian 6.0 PPC, and it seems to be running quite good. I control it using ssh from my windows 7 box. I installed default-jre, so I could run the minecraft server on there.
I've got two questions: I installed Openvpn, but I'm a bit confused on how to use it.. I want people to be able to connect to my vpn network over the internet, what configuration should I use, and could someone maybe link me a decent step by step tutorial?
secondly, when I tried to launch the server, it tried to generate a new map, but this is taking ages! on my desktop computer, it only took two seconds, but after over half an hour, it only got to 20% of "preparing spawn area" what could be wrong with this? Any reason why the java virtual machine would have performance issues? I have no clue.. I haven't tried copying over my smp map from my windows box yet, and launching that.. but I doubt performance will be any better. (my windows 7 machine is hosting at the moment for about 10 people)
When increasing or decreasing the screen brightness, Minecraft crashes and to an extent freezes my computer UI. What I mean by to an extent is that I can move the cursor around, but I can't click on anything. I can also run keyboard shortcuts and type, which is how I restore my system by terminating all java processes with pkill.
What causes minecraft to crash and how can I solve it?
I have 2 computers on the same network that i need to link together to transfer files 1 is a web server the other is a minecraft server. the problem is that the file transfer will be constant as the minecraft server will constantly updates files on the web server and I dont want it to go to the router then to come back to the web server. I want to add a second network card to each computer and link them together and use this second connection to transfer the files is it possible?
Kill me, but) I log into root on my machine, and I downloaded an flv file. I tried to play it with Totem, but it, for some odd reason, kept showing up with big black boxes in it. When I exited Totem, my volume went mute and I can not un-mute it. This only happens to the root account. What should I do?
my rhythmbox used to work fine. i updated my computer and restarted it today and it failed to play anything but does not generate any errors either. however, if i run it from terminal as root it works fine.
so it seems like a few other people have had this issue after an update and seem to blame gstreamer-plugins. i tried a couple of things including removing gstreamers-plugins (good, bad and ugly) and rhythmbox and then reinstalling them all. none of which seemed to work for rhythmbox. (this method seemed to work for mplayer which was also not playing anything after the update.)
I was using the latest stable release of Debian, dual-booted alongside Windows Vista, with the GNOME desktop, installed via netinst, trying to build and install a library that I knew and trusted, when suddenly I couldn't open the Root Terminal. I clicked the link (in Applications->Accessories (I think, whatever the top one is)->Root Terminal), and in the taskbar I saw an item that said "Starting Root Terminal". A few seconds later, that went away, but the terminal still wasn't open. I tried the regular user terminal, to see the same thing happen. Unsure of what was happening, I tried restarting my computer, since that's always the first step you should take in computer problems.
When I restarted, GNOME wouldn't start. The screen would flash a bit for a few seconds, then a dialog box would appear over a background of static that said "The greeter application is crashing. Attempting another one...".t would then go back to the DOS-style kernel, wait a second, and then the same thing would happen. After several of that, I would get a blue screen which said something to the effect of "It has been detected that the desktop environment has crashed six times in the past 30 seconds.
Waiting two minutes before trying again." When it did that, I tried logging in as root to assess the problem. I gave it the correct password, but it said that it was an incorrect login. After several tries (to ensure I didn't mistype the password), I logged in as myself. Same problem. I tried the su command, with the correct password, and it said it couldn't authorise it.
After a lengthy conversation with a friend of mine who was very good with computers, he basically summarised that he had no clue, but that his best guess would be a virus. Upon running the Linux installer, I found the Repair option. Not being particularly familiar with Linux, I used it simply to backup my important files onto a flash drive. I then tried running the Install option, in an attempt to simply write over my existing Linux and make it new again. The installer, however, consistently froze up when trying to start the partitioner, on the "Checking disks..." stage. I figured it was a problem with my partition. In my naivete, I simply used the Windows tools to clear that partition... It destroyed GRUB too, so I couldn't run any OS. I figured my computer was pretty well screwed, and at that point just decided to bring it into the shop and have them completely wipe it.
my computer was backed up onto an external hard driven I brought it back, I reinstalled Windows. Upon restart, it said that it was still looking for GRUB, which made no sense to me. After messing around with it a bit, I decided to just reinstall Linux too. To my lack of surprise, that fixed the problem. Both OS' now ran just fine. The first thing I did on Debian was to install the Clam Anti-Virus, which I understood to be one of the best Linux anti-viruses. However, within about 10 hours, got the same problem as originally. I wasn't doing any of the same things, and between the lack of consistency in activities and the fact that I had an anti-virus running,figured it wasn't a virus. Not knowing what to do, I just left it and have been using Windows since.
I have looked around almost everywhere for a way to run Minecraft on my PowerPC with Maverick, but nothing seems to be working. I'm not sure if it's a problem with getting Java on here (which I can't seem to do without it saying you have to have some other Java file there, or something) or a problem with liblwjgl.so (which is apparently not compiled correctly for PPCs).
I edited fstab to automatically mount my windows data partition on boot, but I screwed it up by not specifying the file system type, however that is not the problem, I was able to fix that easily. The problem was that when it failed to mount the partition, Debian automatically entered root and I guess that is to be expected in order for me to fix it, but I never configured a root password and it just gave me full root access without asking any password, not even my user password. I though that was strange so I set the root password and sure thing it asked me for the root password this time without automatically logging into root....
I then tried to lock the root account to see if it will ask me for a password or not, it did but of course I wasn't able to login as root because it was locked now and I was left with no way to access the system. I had to fix fstab from a live cd so that I can login normally as the user....
I didn't know what to search for or if that is the expected behavior if you don't set root password during installation, but it just seemed a bit strange to automatically enter root when you specifically disable root login during installation...
I'm trying to run minecraft.jar. The download page states that the .jar is executable, but when I try to run it it's as if it was a tarball rather than an executable file. I don't want to extract anything, I want to run it. I tried the instructions on the website: Code: java -Xmx1024M -Xms512M -cp Minecraft.jar net.minecraft.LauncherFrame but that didn't work, and I got this error:
I just changed my sound profile in the sound preferences menu to Analog Surround 5.1 Output, and now since doing that, Flash player in Firefox has no sound and when I play Minecraft there is also no sound. Sound was working before I did this. I have tried reverting back to the previous settings, but that did not work. I tried rebooting, but no successes from that either. Also, when I test my speakers through sound preferences, they work. System sounds also work.
So I was using Minecraft and it was working just fine, but then I got a rather common error. The fix is always to switch over to java sun. I did this, but now it has a black screen when I start the game. I realized after this that I hadn't tried simply reinstalling minecraft. reinstalling it did not fix the new problem. Can anyone tell me either how to switch back to jdk or how to fix the black screen?
I'm trying out the old, free version of Minecraft, and I cannot seem to be able to move. If I press F9, I sometimes get an options screen, and sometimes not. I have F9 bound to scale in Compiz, though I had the same problem with Metacity. If I press any of the movement keys, I do not move, though I can use my mouse. I'm using sun-java6-plugin.
i cant get minecraft to work on kubuntu i found a thread that helped install a different java but i am unable to complete the install because i can not press ok for some reason.
I downloaded an old save that i used when I used to use windows, i switched over to ubuntu and i want to use it again, but i have no clue where Minecraft stores its saves, i know in windows it was the "appdata" folder.
I'm trying to fully automate a Minecraft server, and I decided to use Ubuntu 11.04 on this computer. The computer I'm using for it is an old computer (it's the old family PC, it's about 5 years old (and running amazingly now that I've formatted the hard drive (compared to how it used to run))) so it won't run the Unix environment (or something like that) and runs the Gnome environment instead.
Anyways; the server auto-starts when my computer turns on (my computer also automatically turns on). Now all I need to do is have my computer auto-shutdown at 12:00AM as well as enter the command "stop" into the running terminal. I plan to later add more commands (such as automatically welcoming people to the server when they connect, but that's not important right now and I'll likely be able to figure out if I can get this working).
This is the command I'm using to shutdown the computer:
sudo shutdown -P 24:00
However, it doesn't work. First of all, I need to enter my password, so I need some way to have the shell file enter my password for me whenever the terminal asks for it. Second of all, it just plan doesn't work, even if I enter my password (like, the countdown doesn't appear). As for entering commands into the terminal, the only way I can think of is:echo "stop" But the problem is that doesn't work because it wont enter into the running terminal (and I don't know how to do that).
each and everytime I close Minecraft window it puts my 1024x768 15" screen from 75hz to 60hz and this occurs EVERYTIME I close Minecraft, I have tried uninstalling then re-installing Minecraft.
I wasn't sure weather to post here or on the minecraft forums.
OS: Ubuntu 11.04 x86 CPU: Intel core i5 sandy bridge 2410M GPU: Intel HD 3000 (Integrated) RAM: 8 gigs ddr3
So I got my new laptop a few days ago,loaded up ubuntu.After starting up minecraft to connect to my server I realised that the fps was going from 50 to 1 and back to 50 again EVERY SECOND so obviously this isn't normal.After a quick google search every one on windows seems to have no problem. There are no results for linux.
Edit: Yes I know why the are you using a x86 os on a computer with 8 gigs of ram? At the time of installation all I had was no internet access and a live cd from LUD with ubuntu on it
I'm on Ubuntu and I don't lag none the less at all. Is there a goood video tool that can help me record minecraft with little to no lag at all? Or some trick because I think I set my java priority higher than usual. I have only 2GB of RAM
Ok so i have just searched and searched and i have minecraft on my cumputer and i run it and click run offline and it goes black and after about 5-10 seconds this error comes up in the minecraft window
I want to make a script that specifies how much ram to launch minecraft server with, so far I have:Code:read $ra java -Xmx$raM -Xms$raM -jar minecraft_server.jar noguibut I knowthat that won't work because there is the M at the end of the variable $ra, is there a way I could make this work? I believe that the M at the end is required to specify the measurement unit.
When I run a java application (minecraft) the computer occasionally freezes. I'm not sure which version of Java I have. The online java app for telling you which version I have says that I have an old version. The command line says I have an up to date version. If I need to update Java Sun , how do I do it ? I followed the instructions once and didn't work.
I installed Fedora 15 last week, on my main PC, and I absolutely love it. Defintely my favourite operating system. Now I have a few questions. I thought I would put them all in one thread, instead of making seperate ones. I did search before I posted, and I cant seem to find any solution to my problems. So here it goes.
First question, I am using evolution for my e-mail program/client. My email addresses are all hosted by hotmail. Now I have set them all up correctly, but cant seem to send e-mails(I recieve them perfectly fine). I am using the "smtp.live.com" server, and using SSL encryption. I have tried messing with the settings but have had no luck. Has anyone figured out how to fix this?
Second question, I play minecraft frequently, and I am currently starting the program via terminal [java -jar /home/username/minecraft.jar], which works flawlessly. However it is too slow(open terminal, type it in. I need a simple click), is there any other way to start minecraft?
Third and last question, What is the best way to close minecraft? I notice if I just close it(via right click, and close, or clicking the X) it freezes and stays open for a long time. Is there any better way to close it?
