Ubuntu :: Opening Mathematica Via SSH X-window Sporatically Quits All Programs And Logs Out?
Jul 27, 2011
I use Mathematica 7.0 through my school's SSH server. This involves:
-loading their font server via "xset fp+ tcp/c1.ucalgary.ca:7100"
-connecting to the SSH server via "ssh -X useruser@servername.ca"
-entering my password Then I choose to run Mathematica via ". use mathematica 7" then to load the GUI "mathematica".
Sometimes, and only sometimes, the screen goes to the error in the attached picture, stays there for about 5 seconds, brings me to the login screen. When I log in again, all of my applications that were running, open folders, and my terminal windows are closed.

how to make a program open in a window, much like the -w command you can put in a launcher under gnome. Alternatively if someone could guide me on how to install gnome in lubuntu i could just give that a try too..

was a regular windows user for ~10 years now, but my current pc wasnt installing windows for some reason so i switched to linux to try it out. I've been trying to run a few small games here and there to keep me entertained, and wine just isnt agreeing with me ... Any program i try to open with wine, it says "opening _____________" in the taskbar, and then NOTHING HAPPENS! This is really irritating me, becuase if i got an error message i could try to figure out whats wrong, but when NOTHING AT ALL happens

I'm wondering if it's possible to write some sort of script so I can have an icon on the desktop which opens a combination of programs I use together frequently.Specifically, I would like to have an icon called "keyboard practice" which does the following:
1) Open QJackCtrl and "click" on Start;
2) Open the Hexter softsynth and make the Jack connections between it and my speakers;
3) Make the Jack MIDI connection between my MIDI keyboard and Hexter.

Well title say it all how do you disable the screen programs opening text in 11.04 so you do not have to hit the enter key twice to get by the two pages of text to actually be running the program you started.

How do you open a program, in this instance "Zenmap", from the desktop in a user account when it requires root privileges? Is there a way to be prompted for the password, the same way, for instance, you're prompted when mounting a new file system or making a change to the system? I tried entering 'sudo /usr/bin/zenmap' when creating the shortcut, however that didn't work.

I would really like to stop Konqueror opening up links from Skype and other programs. It's becoming annoying because I have Chrome set to be the default browser, but for some reason when I click on a link it opens in Konqueror.

I am fairly new to Ubuntu and was wondering if anybody knows of a way to open up a number of programs and placing them in specific spots programmatically. Basically, I'm trying to avoid having to open my IDE, multiple terminal windows, browsers, etc... and then having to place them all in the exact position I want when my machine boots up. Ideally, I could say:Program A, is placed on Monitor 1, workspace 1, at position 0, 0, with height and width 600 x 400. Program B, is placed on Monitor 2, workspace 2, at position 600, 500, with height and width 1000 x 600

Some windows programs won't run after I have installed them with Wine. They either won't run or they make the screen go to a black painting screen (screen goes black and you can paint over it with your mouse to make the desktop reappear). I have tried changing the windows version and made no difference. I have even tried opening it in a virtual window and made no difference (Window opens then closes)

When I turn on my computer I am greeted by an unending stream of "Starting File Managers" appearing in the programs list. This cannot be stopped, though none of the file managers actually open. They just sit there filling up my programs bar and wasting my cpu slowing down computer. It also means I cant upon my own folders, or see what programs I have open.If I run terminal, type xkill and click on one of the buttons in the programs list, that kills them all, and I can see my programs again for a bit, until it fills up again. The panel disappears and appears again, with all the spawning messages gone and any other programs I have open remain there. Its just the randomly spawned "Starting File Managers" that don't come back.
My CPU fluctuates. Its around 60% to 90% load, when it should be idle, but is instead opening all these windows.When I view the processes the most CPU intensive (when I sort) is Gnome System Monitor at 6% and then Gnome panel at 5%,gconfd-2 is as around 2%, compiz.real, dbus-deamon hover around 1%. And everything else is generally at 0%.So somewhere, a hidden process is using about 70% of my CPU load. Which isn't shown in system-monitor. Maybe because its an admin process and I can only see simple user processes. I dunno.There is something else though. I have a process with no name appearing, its blank. And it keeps disappearing and re-appearing. So you can hardly select it hard enough to kill it. I managed to kill it once and it said error, process (large number, 10,000 or 100,000) does not exist. So can't be killed.When I do an xkill the console writes:
Code:
anthony@Anthony-Acer:~$ xkill
Select the window whose client you wish to kill with button 1....

I like to alias my firefox commands so I can open up mutiple pages at once. This works great. firefox [URL]
But if I have firefox already up and running it will open as tabs of the firefox I already have running. How can I open the multiple pages in a new window in this case?
- Using -no-remote could work, but I would have to make a whole different firefox profile for each set of pages, not really a solution. - Also tried setting it to a particular display and it opened as a tab again. ie. firefox [URL] -display=":0.0"

In Pidgin browser preferences, it's set to open in new tabs. But when I click on a link in IM, it opens in a new window instead. Is this because I use Google Chrome in the Incognito (Private Browsing)?

I use firefox3.6.x, and i play online video (sockwave flash) often, but while opening the page (often has swf), the whole X restart, and back to login window of gdm. The problem not accured everytime i open the page, but very often. I met this problem both in ubuntu 9.10 and 10.04, and also lubuntu 10.04. So, i fall back to use firefox 3.5.9, and evrything seems fine.

When I VNC into my CentOS server I am always met with the usual GUI and an annoying terminal window. If I try to close the terminal window it reappears immediately. I can only minimize it to the taskbar. Am I missing a simple setting to disable this?
Here is my xstartup file:
#!/bin/sh
# Uncomment the following two lines for normal desktop:
unset SESSION_MANAGER
exec /etc/X11/xinit/xinitrc
[code]...

I have a program that runs fine from the terminal, but when I put it into the Startup Applications it doesn't work. Where can I check the logs to see what the problems is? By the way, this is the command:
bash -c "sudo dbus-launch path_to_program --debug > path_to_debug.log"

I've recently installed ubuntu, and right away from a fresh install programs would crash whenever I closed the last window. It doesn't give me any error messages, so I don't know what the problem is , just poof the programs is gone and I have to launch it again. This happens in almost every program, I've used except rtythmbox. it's not a big deal for the small programs that load instantly, but for firefox or openoffice it's big pain in the neck.

I have a huge set of events in Mathematica that I need to react to, and it's not practical always checking for it, especially since events are randomly distributed in time.So I wanted to add a simple sound to remind me to go check the event. I wanted to use Beep[] but I get no results, in fact, I didn't realize till now that mathematica is making no sounds whatsoever.I use Debian Squeeze Stable and have no trouble with any other application using sound.

Since I have upgraded to to 10.10, I've noticed that I can no longer drag programs to another desktop. Somehow this setting must have been disabled. How does one reactive this setting? (I'm guessing its Compiz related...)

Many commands in Mathematica 8 (Integrate, Simplify, etc.) seem to only be using a single core on my system. Is there any way I can change the affinity so that it utilizes all cores for computations?

I lastly used KDE (version 1.x ). Now I'm using KDE 3.5 for several weeks and one thing really annoys me: there are a lot of programs that don't remember their last window position and/or size. They always default to a specific location/size when I close and open them again. I give you some examples:
Program that doesn't remember anything:
- Konqueror
Program that remembers window size, but not position:
- KMail
Nice Program that remembers everything:
- Basket Note Pads
Is there a way to tell these programs to remember their position/size?And a second question about konqueror: Can I tell konqueror to remember the view mode? I prefer MultiColumn view, but it always defaults to Icon view.

I Install Mathematica 4.0 on Ubuntu 10.04 and fedora 13. When i create new notebook file and save it, Mathematica front end automatically disappear. It shows message "Mathematica has received the signal: SIGSEGV and has exited" on terminal. But this not happing on older Linux version such as suse enterprise desktop 10. if i first create aaa.nb file using vi editor i can open it with Mathematica front end and save it. but cannot do "save as option" and also cannot open edit-> preferences menu.

Can't seem to open certain things. For example Synaptic Package manger. It just shows "starting" etc and then nothing. Same thing with partition edd root terminal.Terminal runs fine (and i can su root from there) as do other things such as firefox,em monitor,update manager add/remove applications. apt-get still works fine. Just want to mention i have 500 megs of ram. Any ideas? Are there logs dumped somewhere for this kind of thing? Synaptic package manager still runs using dpkg from the terminal.
