[Bug 253504] Re: adding sudo before command in launcher in gnome panel freezes X session
When I click on the launcher, there is no response (none visible). Even issuing the following command on a terminal shows no output ps -e|grep sudo. This shall mean that it is not even running in the background (as earlier mentioned by Sebastien). I think this is a bug in itself (as there is no response to the command). ** Changed in: gnome-panel (Ubuntu) Status: New = In Progress -- adding sudo before command in launcher in gnome panel freezes X session https://bugs.launchpad.net/bugs/253504 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 253504] Re: adding sudo before command in launcher in gnome panel freezes X session
Hello, The old server I originally encountered this issue finally succumbed to age and is no more. Since then, I have built a new server. I tried to reproduce this issue on both my desktop and my server. The desktop is running a fresh install of 9.04 and I am not able to reproduce the issue there. The sudo process does not even appear in top or in gnome system monitor which is not the expected behavior (but is desirable I suppose). The desktop does not lock up. This is the same behavior I had on my desktop originally. Very surprisingly though, (or maybe not) I am still able to reproduce the issue on my server which is running Ubuntu Server 9.04 64-bit with X and gnome installed. The original problem was also on the server version of Ubuntu. Maybe that is why people recommend not running X on a server? :) It's a little different now in that I am able to switch to a VT via CTRL+ALT+Fn, login, kill the process, etc. whereas before this did not work. Other than that, the session is frozen just like before. -- adding sudo before command in launcher in gnome panel freezes X session https://bugs.launchpad.net/bugs/253504 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Sebastien, what is the expected behavior in this situation?

[Bug 253504] Re: adding sudo before command in launcher in gnome panel freezes X session
I tried it on a different computer running 8.04.1 Desktop (as opposed to 8.04.1 Server with X and Gnome installed). I was unable to reproduce the issue. The launcher did not open the application and I also saw that sudo was not even running after clicking the launcher. However, the machine did not lock up. Is this the expected behavior? On the original computer having the problem, I get the issue every time assuming the sudo ticket is not already available. I am unable to switch to a VT after getting the bug. I must SSH to the machine and kill the rogue processes. Maybe it's a video card driver issue? The computer where I am able to reproduce the issue has a ATI Radeon 9600 XT and the one that is not having the issue is a NVIDIA GeForce 8800 GTS. -- adding sudo before command in launcher in gnome panel freezes X session https://bugs.launchpad.net/bugs/253504 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

thank you for your bug report, I just tried on my intrepid installation and can't confirm the issue. was the cursor stucked in busy mode when you had the session frozen? did you look to /var/log/messages and /var/log/syslog after the reboot? was there any useful message there? if ctrl-alt-fn was not working that's not likely a gnome bug ** Changed in: gnome-panel (Ubuntu) Importance: Undecided = Medium Assignee: (unassigned) = Ubuntu Desktop Bugs (desktop-bugs) Status: New = Incomplete -- adding sudo before command in launcher in gnome panel freezes X session https://bugs.launchpad.net/bugs/253504 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 253504] Re: adding sudo before command in launcher in gnome panel freezes X session
Thanks for the fast response, Sebastien. The cursor was not stuck, it remained an arrow. However, the default animation that plays when clicking a launcher (icon gets bigger and bigger while fades) was stuck. The icon appeared large and transparent when the screen froze and the keyboard became unresponsive. I looked in /var/log/messages and only saw entries for when I pushed buttons on my KMV switch (for disconnecting and connecting USB devices). /var/log/syslog only had some info about cron jobs which I did not create so they must be setup default. If the mouse was still moving, but the keyboard and screen were not working, could it be a bug in X or compiz? I will try to reproduce the issue and report back. -- adding sudo before command in launcher in gnome panel freezes X session https://bugs.launchpad.net/bugs/253504 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 253504] Re: adding sudo before command in launcher in gnome panel freezes X session
I was able to reproduce the issue by adding sudo before my gnome- terminal launcher as well. I was actually hoping I would not be able to reproduce the issue :) The animation did not get stuck this time but the keyboard became unresponsive again. When I SSHed into the machine the sudo process was occupying 100% of the CPU according to top. I wasn't expecting that. Killing the sudo process did not make the keyboard start working again. I had to kill xinit at which point I plopped back to a terminal and everything was fine again. Second time I tried it, I killed sudo, killed xinit and all the gnome panels and desktop icons disappeared but I could still see my desktop background image. At this point CTRL+ALT+Backspace worked and I was back the terminal. This seems strange. The only thing I have noticed in the logs that seems out of the ordinary was this line in syslog which appears after I type startx: Jul 31 22:41:25 machine_name console-kit-daemon[6278]: WARNING: Unable to activate console: No such device or address Maybe that is normal.

[Bug 253504] Re: adding sudo before command in launcher in gnome panel freezes X session
Well, I saw the notification in the panel that some updates were available. I noticed one of them was for gnome-panel (and other packages). I thought why not? and installed them. I then tried to reproduce the issue. Having a sudo before the command in a launcher is no longer locking up the X session! Instead, it opens the tool with root access. I was surprised. However, it never prompted me for a password. Is this because I had already specified it when I ran the Update Manager tool? I tried logging out and back in to see if that would reset it, but I still was not prompted by the launcher. However, attempting to execute the same command from the terminal did prompt me to enter my password. I was able to execute sudo gnome-terminal from a launcher on my panel, it opened a terminal with root@machine name and I indeed had root access (tried to write some files in other users' home directories). I am completely confused now. Is this the expected behavior? Should the user not be prompted for a password when running a command prefixed by sudo from a launcher in a panel or is this working by chance because I performed a system update right before the test? -- adding sudo before command in launcher in gnome panel freezes X session https://bugs.launchpad.net/bugs/253504 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
