Fluxbox menu -> starting matlab

CerebrosuS · 2016-08-19 11:58:52

Hey guys,

I try to start matlab from the fluxbox menu. The entry in .fluxbox/menu is:

[exec] (MATLAB 2016a) {matlab -desktop}

Typing 'matlab' directly into a urxvt instance of bash works.

After pressing the menu item, the splash screen of matlab pops up, but it goes away without displaying the application. (Like using 'matlab' without the '-desktop' option)

Any suggestions?

Greetings

What happens if you run 'matlab -desktop' in urxvt? Any error messages?

Just an information from OpenJDK8 that maxMem ist not supported and will be ignored. That happens since I switched to OpenJDK instead of the matlab oracle jdk. But the problem has also been there before I switched to OpenJDK, so I don't think that this is the problem.

Any other information needed?

Greetings

How about

[exec] (MATLAB 2016a) {urxvt -e matlab -desktop}

Thx teckk, that worked. But it always opens a additional konsole. Also, I want to understand why the problem occurs.

I haven't been using matlab. It looks like matlab needs the shell to stay open for it to run.

urxvt -e matlab -desktop opens an instance of urxvt and the -e switch opens an executable in it. Look at man urxvt

You can run anything that you want from fluxbox's menu that way.

Examples:

[exec] (Sleep) {sudo systemctl suspend}
[exec] (TCPdump) {xterm -T TCPdump +sb -g 80x45 -e sudo tcpdump -q -t -n -i any}
[exec] (Inox) {inox --disable-gpu --disable-infobars}
[exec] (MyBrowser Gtk WebKit) {~/mybrowser_Gtk.py}
[exec] (Clear Firefox cache) {~/.cache/mozilla/clear}
[exec] (Rox as Root) {sudo -E rox -n}
[exec] (USB drive FAT Mount) {sudo mount -t vfat /dev/sdb1 ~/usb}
[exec] (Capture Audio to mp3) {ffmpeg -f alsa -i hw:1,1 -c:a libmp3lame -b:a 32k -vn capture.mp3}
[exec] (Edit Menu) {geany ~/.fluxbox/menu}

No experience w/ matlab, but you could try

[exec] (MATLAB 2016a) {nohup matlab -desktop > /dev/null & disown %1}

Thx seth,

as your solution removes the terminal. I still don't understand why it doesn't work with matlab -desktop only, but that is enough for me now.

Thx to everyone who helped me in solving this problem.

Hey,

is there a way to mark the Thread as [SOLVED]? Or is there no need for documentation?

See eg. http://unix.stackexchange.com/questions … disown-and

Notice" that nohup + disown will make the entire thing very "aggressive" about staying alive.
matlab won't implicitly close on a logout - unless it's (I assume) a graphical process and dies when loosing the X11 server connecetion.
