[SOLVED] Help needed with auto start scripts for java server program
location: linuxquestions.com - date: October 22, 2011
I'm very new to Linux scripting so I'm hoping someone can help me out here. I want to start a java program on startup as user "user". I have 2 questions.
1. Does rc.local run as root? If so is there any way to su - user within the script or to tell rc.local to launch something as user?
2. What is wrong with my script below? It echos fine but won't start the program daemon. (it works fine when I type the command directly into bash)
echo "/usr/bin/java -jar /home/user/mekwars/Server/MekWarsServer.jar & " >/home/user/Desktop/mekwars_startup_log
/usr/bin/java -jar /home/user/mekwars/Server/MekWarsServer.jar & >> /home/user/Desktop/mekwars_startup_log
Permissions are set as
-rwx------ 1 user user 187 Oct 22 17:04 mekwarsStart.sh
Thanks for any help on this, I know it's probably something stupid with the script.
Dropping bluetooth connection on Ubuntu 11.4...help needed.
location: ubuntuforums.com - date: July 27, 2011
I run Ubuntu 11.4, fresh install, on Acer Travelmate 5520G. I'm having a problem with using a bluetooth headset with it. Whenever I try the connection drops after a while (shorter or longer, this is really erratic...).
When this happens the headset is still listed in the bluetooth preferences but reconnecting is not possible, only through removal and re-discovery.
I've investigated and here are my findings (I'm not a superuser so please treat me as a beginner):
1. The connection with the headset can be established, headset is added to the devices as well as shows in Sound Preferences having been added.
2. Sound can be routed through the headset.
3. The connection drops suddenly without a visible pattern after an arbitrary length of time - 30 sec or can go till disconnected by hand.
4. Re-connection is not possible. The headset disappears from Sound Preferences, although it's still present in bluetooth devices. Attempts to reconnect fail. /var/log/syslog shows:
Ubuntu and Ham Radio! DSTAR help needed...
location: ubuntuforums.com - date: December 31, 2010
I am assuming there are some other amateur radio operators out there using Ubuntu. Is there any Linux based radio programming software for the Icom IC2200 and/or the Icom IC-91AD? I have the windows(xp) software for them and the cables, I was just thinking it would be nice to do it in Linux.... since the DSTAR network is built in Linux.
Help with program installation.
location: ubuntuforums.com - date: May 16, 2010
I'm fairly new to using ubuntu, i've had in on my netbook for a few months now as my older brother said it would work better, which it does. Though I don't know the first thing about ubuntu.
I've been trying to install a program called Zekr which is a islamic program that recites the quran. It installs through the software package manager fine and when I try it open it I get an error message which says;-
"Uthman-taha experimental theme cannot be used. Install tff-me-quran to enable uthman-taha theme."
When I try and install tff-me-quran with the instructions on the zekr website it won't find the file.
Is there any other way to get this program to work?
Any help would be appreciated.

NAS on btrfs (possibly zfs/xfs) advice/help needed (softwaregetting started)
location: linuxquestions.com - date: June 28, 2010
Thanks for reading this question and any help and advice you are able to provide.
Currently have multiple small DNS-323 NAS-in-a-box that need to be replaced with a single storage server.
HISTORY: Since the setting is for an advanced home server (2-3 simultaneous clients max) that will hold movies and application/game ISO's, I was originally going to go with a simple RAID6 on freenas. As I learned about silent data corruption, and with a max of 3 simultaneous users, I don't see a need for a hardware raid processor. So I gathered that software RAIDZ (RAIDZ2) based on ZFS or BTRFS that prevent silent data corruption would be a better match (please correct me if I am wrong).
NEEDS: The needs (in addition to prevention of silent data corruption) are basically online capacity expansion (OCE), and 2+TB volumes (64bit LBA); with a preference for the ability to spin down idle drives. I'm going to make the assumption that any solution I go with will allow me to read/monitor actual

[SOLVED] No keyboard input or fullscreen with fps games, help needed.
location: ubuntuforums.com - date: October 19, 2008
Always when I try to play any fps game, it works a couple minutes ok.
But then, fullscreen goes off. It now fills only 1/4 of my screen, the rest I see is my desktop.
And no keyboard or mouse input! It seems to be that the game window isn't focused.
I can't restore focus with alt+tab because keyboard presses don't register! And mouse doesn't work either.
Cursor isn't even visible. It is probably focused on the game window, but when I move my mouse, nothing happens.
But the game isn't crashed. I can still see other players running on the game window.
So what's the problem? Some other program stealing focus? I don't have any other progs open.
