glad you soved it, I should probably set /bin/bash instead of /bin/sh

I tried simply running 'xlaunch xterm' which launched full screen but didn't allow for any input. I had to Ctrl-alt-backspace to get out. (AIGLX on Ubuntu 6.10 (Edgy)). In any case, I have figured out that I can use beryl-manager to change my WM from Beryl to Metacity and back again when desired. Using this rather cumbersome method, I can launch any game I like sans xlaunch. I'll continue to play around with it and report back if I figure it out.
I appreciate your time. Thank you. |

I notice that the following is being used:
Code: |
if [ "$EUID" = "0" ] || [ "$USER" = "root" ] ; then
|
Don't do this -- at least, don't check for "$USER" being equal to root since anyone can change it:
Just check for the $EUID, this is a read-only environment variable.

You recommend the change in /etc/profile -- and whilst the initial check might not even be yours -- the use of checking $USER is completely unnecessary and dangerous.

oh, I use the $USER env variable in the script, but it is just ignore if you don't use the "XPLAYER" feature, and even if you do, I don't think there is anything dangerous, but I can be wrong. anyway, so what would you recommend to me, using $UID right? _________________ The End of the Internet! |

Yes, consider the following:
Code: |
[n6tadam@workstation ~]% echo "$USER"
n6tadam
|
Which is fine, but then:
Code: |
[n6tadam@workstation ~]% USER=root && echo "$USER"
root
|
Oops. It's not a reliable means of ascertaining if a user is root or not. Plus, if you then had commands thereafter to change one's PATH or what have you, that's just going to be bad all round.

Could you say exactly how you're using this option? I think you can use the -screen option as I described here(second part of the post) how to use the -config option.
I didn't know this option, but it looks like it's even better than the -config one _________________ The End of the Internet! |

there was a problem with xlaunch when the arg/options to the program had spaces in it.

Hey, very nice work here, truc. I'm having a strange issue running the script from within X though, maybe you or someone else here know what's wrong.
If I login to another text-mode tty (i.e. ctrl-alt-F2) and run a program with xlaunch, everything works fine. However, if I run xlaunch from an xterm or a graphical menu in X or whatnot, performance is much worse than it should be. The exact same parameters are used both times.
I'm using updated nvidia drivers, Xorg 6.9 on Slackware. I don't have any fancy composite WMs running.
As an aside, I thought I was having issues running the script in zsh, but it seems to work fine if I specify the path to xlaunch when running it.
Merci beaucoup! keep up the good work |

this is wierd :O
When your in X you should check if variables such as __GL_FSAA_MODE are set (used for antialiasing and things like that). this is the only thing I can think of, so check your env :/ _________________ The End of the Internet! |

Nope, definately not the problem. I'll keep experimenting and report back if I find a solution (or the cause of the problem at least ).
EDIT: Bah, nevermind, I must have just had some secret runaway processes or something... everything's working fine after a reboot. (What is this, Windows 98? )
Thanks for the help anyhow. |

very complex script with a lot of features in mind!
I just wonder how it would be to include (seperate) root access.
I know that root cannot use it by design for security reason but I am looking for a solution running seamonkey, firefox or thunderbird with root
access for installing several xpi plugins.
other tools like k3b sometimes also need more privileges (e.g. for testing device access)
how would it be if your script has something like an switch which gathers root privileges via su/sudo and then executes x based apps
for installation/maintaining purposes.
Suggestions or Alternatives??? _________________ Optimism is solely an absence of information. / Optimismus ist nur ein Mangel an Information.

I'm not sure I've understood exactly what you want you want to start an X session being root?
What's preventing you from running this script as root?
Also, if you edit your sudoers file you can even run this script as a normal user, and launch the different application as root (including the Xseesion), have a look at the "XPLAYER" feature, (I didn't find better for the name )
around line 316
Code: | case "$PROG_GROUP" in
games)
if [ -h "$0" ]; then
XLAUNCH_PATH=`readlink $0` || echo "Error: could not read the \"$0\" link"
fi
echo "Launching ${FULL_PROG_NAME##*/} as user: $XPLAYER"
sudo su - $XPLAYER -l -c "FULL_PROG_NAME=\"$FULL_PROG_NAME\" ${XLAUNCH_PATH:-$0} ${*// /\\ }"
exit $?;;
error)
echo "Could not determine group of ${FULL_PROG_NAME}. (Do you have 'stat' on your system?)"
echo "Launching $FULL_PROG_NAME on DISPLAY=$DISPLAY_TO_USE as user: $USER"
;;
*)
;;
esac
|
you can very easily create a script which will launch your different programs, chgrp it, then ass the case for this group in this loop, and either modify the XPLAYER value (set it to root) or even add your own new variable
I'm probably not very clear, but I explain a bit this on the first page, so you might wana have a look _________________ The End of the Internet! |

sorry for obfuscate my intention - sometimes i think/write too much in general terms.
when i can run this script also via sudo then everything is ok
thought the script path (and because of that access for root was denied) because of the line in /etc/profile
Quote: |
in /etc/profile, replace:
if [ "$EUID" = "0" ] || [ "$USER" = "root" ] ; then
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:${ROOTPATH}"
else
PATH="/usr/local/bin:/usr/bin:/bin:${PATH}"
fi
with the following:
if [ "$EUID" = "0" ] || [ "$USER" = "root" ] ; then
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:${ROOTPATH}"
else
PATH="/usr/local/bin:/usr/bin:/bin:/home/scripts:${PATH}"
fi
|
will have a deeper look in script now!

So I'm trying to use xlaunch to run another script of mine. The contents of the other script are:
wc3
Code: |
#! /bin/bash
setarch i386 -X wine ~/.wine/drive_c/Program\ Files/Warcraft\ III/Frozen\ Throne.exe -opengl
|
When I run $xlaunch wc3 it says:
Starting /home/scripts/wc3 on DISPLAY 1
It then prints out 50-ish line feeds,
then it prints xrdb: "XTerm*boldMode" on line 19 overrides entry on line 3,
followed by around 100 prompts (user@localhost ~ $).
Sometimes it will NOT have the line feeds or the prompts, other times it will, but the rest is always the same.
It seems to more frequently print them (last 5 or times I tried, as I was trying to find some sort of correlation(I didn't)), than not.
Thanks,
-Kevin |

I do also have sometimes the 100 prompts, and sometimes don't, I just don't know why
Anyway, so your script isn't working?

It's a step closer, instead of opening the new session and doing nothing, it now opens the session, shows the little box while loading, then the whole thing dies, session and all.
Heres the output (after removing hundreds of line feeds (what is with this, I see this using xlaunch with other things as well))
