Ubuntu :: Gksudo And Gksu Stop Working?
Jan 20, 2010
I am running a file server on Jaunty. It was a fresh install about a month ago and I have been having problems ever since. I connect external drives to the machine to do nightly backups. Lately, I have been using GParted (Gnome Partition Editor) to format the drives before using them as backups, as I keep a backup for every day of the week.
After using GParted a couple of times, it will stop working and I can't open it or any other application that needs root privileges. I can't use Gnome to mount drives anymore. I have to open Terminal and use the mount command to mount drives. Trying to start gparted or any other application, including nautilus from the Terminal using gksudo or gksu, I get the following error message:
Code:
gksudo nautilus
(nautilus:25353): nautilus-extension-gnome-mount-WARNING **: Cannot connect to system bus: org.freedesktop.DBus.Error.LimitsExceeded : The maximum number of active connections for UID 0 has been reached
(nautilus:25353): nautilus-extension-gnome-mount-WARNING **: Could not initialize hal context
[Code].....
Once the machine is rebooted, everything works fine until I run a few more privileged applications, then the applications stop working again and this whole process starts all over. The only way to fix the problem so far is to reboot the machine, which is completely unacceptable.

This comes at some point after installing GNS3 and Dynamips, which require administrator access as GUI's. Although, the first couple times I tried to run GNS3 as administrator, it worked fine. I do still receive the password prompt, whether running from the command line or the context menu. Note that GNS3 is the first application for which I've needed to run gksudo, so this may have been an issue before the above were installed, although I've always been able to run "Open as Administrator" in Nautilus and "Synaptic Package Manager," which now will not run either.
Running Ubuntu 10.10.

I installed lubuntu 10.10 from a minimal netinstall. For some reason, the main menu entry for synaptic package manager uses gksu instead of gksudo at the beginning of the command, as revealed by right-clicking the entry, then clicking "properties". This, of course, precludes the ability to access the program unless you're among the few who have activated the root user account. That's a problem in and of itself, but it's been recognized elsewhere. However, after I fixed the command and clicked "ok", nothing changed. I opened up the little properties menu again and it was gksu, as though I hadn't fixed the command.
The properties window is a mysterious little program called lxshortcut. I suspect that if I run lxshortcut using sudo, then the changes I make will actually stick. Problem is, I don't know how to find the actual location of the main menu's SPM shortcut/launcher-thingy. Nor are there any clear instructions on how to use lxshortcut in terminal. I flailed about with my best interpretation of vague instructions, but to no avail.
I downloaded alacarte (which is, of course, intended for gnome), and I got the software sources entry to show up in the list, but nothing else in the program responded when I clicked. The whole experience in alacarte was weird and unhelpful and somehow I've outright removed the menu entry for synaptic. And that's fine, I barely use it anyway, but Software Sources also has the same gksu problem, and I actually use that one. So how do I change the command associated with one of the preferences in the lxde/lubuntu main menu?

I can enter my password just fine to log into the system, and using sudo from a terminal also works, but "gksu" does not. It tells me my password is incorrect. That means Synaptic doesn't work unless I "sudo synaptic" from the terminal. Anyone else happen to encounter this yet, or is it just me? I started with a clean install of Kubuntu 10.10, which I later installed ubuntu-desktop over and then removed. Would that possibly make a difference here?

I've been having a problem with administrative apps all the way from last years' distros, and in 10.04-x64 it's still here.
When i launch an application that needs gksu, it simply hangs waiting for a gksu window that never shows up.
If i launch another administrative app, it hangs as well.
When i look at the process list, i get a lot of gksu instances, all sleeping.
if i kill those processes, the mentioned apps resume with an authentication error
But if i use a terminal and type sudo <app>, it hangs for a few seconds, then prompts for password and it works fine.
I don't know why it works so badly, but it needs to be fixed soon, many new users will surely find this very frustrating.
I run ubuntu 10.04-64bit on a AMD-Athlon-x2

When I try to open Transmission I get a message: "Couldn't open "/home/shai/.config/transmission/lock": Permission denied", and the only way to open it is by using gksudo.
I read on another thread that I need to delete that file, but the file doesn't exist.
What should I do?

gksudo nautilus sets the background to default (Because nautilus is rendering the desktop) I set the gconf key to stop it rendering the desktop, but this only affects the icons. How can I get it to give me back my background? Edit: Fixed the desktop (--no-desktop option on nautilus command) - need to find how to kill the nautilus process automatically when I close it.

On Linux Mint, there is this theme called WildMint, looks somewhat like an older Ubuntu Studio theme. Anyway, I have been trying to find how to get it to work on Ubuntu instead of Mint. It is nowhere to be found on Gnome-Look and I've tried to search everywhere for it. Also, I've tried just copying the folder from /usr/share/themes but I just get errors even when running Nautilus under gksudo.

This occurred sometime in the past couple of days, perhaps because of an update that I just blindly accepted or due to some tinkering of my own. But for some reason, my gksudo never remembers the password I put in there anymore. When I sudo in a terminal it remembers no problem, and my sudo-via-terminal also responds to the "timestamp_timeout=x" variable in /etc/sudoers as it should. But does gksudo have it's own "/etc/sudoers" file where you can override the caching period for the password or does it reference the regular /etc/sudoers also?

I am running 9.10 (Karmic) on a Compaq Presario CQ60 laptop with Nvidia graphics. I have installed the -185 driver which has solved most problems. However every so often the system seems to lose track of the mouse button state. The first symptom of this is that all mouse movements on text are treated as if the left button is being held down: mouse movement selects text rather than just moving the graphics cursor. I am using a M$ optical mouse.
I have tried:unplugging and replugging the mouse using Ctl-Alt-F1 to go into a console and Ctl-Alt-F7 to go back to the GUI I am able to shut down all of the open windows normally using the keyboard, but the only way I have so far found to get the GUI working again is to reboot the system.

I recently did a clean install of ubuntu 10.4 and finally got everything working. All of a sudden my sound stop working and i can seem to tell whats wrong. The strange thing is though when i first turn on the computer i can here the drums at the login screen but after logging in there is no sound anywhere. I checked all the sound preferences and everything looks alright, nothing was muted. I am pretty much stumped..

I was having a problem with the mouse and keyboard randomly failing to work after upgrading to version 10.04. I tried both the 32 and 64 bit versions. The problem went away after I edited the file /etc/default/grub and changed the following line:
from
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash noapic nolapic"
If you are unable to open a terminal window, try doing the following
Ctrl+Alt+F1
Log into you account.
sudo nano /etc/default/grub
After saving your changes and exiting nano you can reboot by using the halt command.(FYI Ctrl+Alt+F7 gets you back into X server -- but you need to reboot for the change to take effect) Update: problem recurred. I had to do Ctrl+Alt+F1 to log into a console. I executed 'ps aux | more' to find the PID for X.Using the PID I restart X with 'sudo kill -S SIGTERM <PID>'.Once it started up again it was fine.

Until yesterday, I used the scroll key, middle click, to open/close tabs at Firfox and chrome, today for some reason is not working any more.
I can roll pages up and down, but at Firefox and chrome i cant open/close the tabs with scroll/middle click.
I checked online and the only fix I found was the safe mode solution, which I don't know how to do this on Ubuntu.
I reinstall Firefox and chrome but same thing happens.
I think its something at about:config. I mess around with it, tried all combination, seems nothing happened there for me, no reaction at any changes.
Kinda noob at Linux so if you could explain any solution like talking to 5yo kid would be appreciated.
Ubuntu 10.04 and Firefox fully updated.

I recently bought a Shuttle XS-35 Mini-Barebone-PC and filled it with a 2GB Corsair RAM and a 1 TB WD Scorpion Blue Drive.After assembling all the parts I simply wanted to install Ubuntu but it simply doesn't work. However then I had the idea it would be good to kinda get the drive to a completely clean state and used the tools to safely wipe the whole HDD (by writing zeros everywhere as the tool tells me). The tool ran good for around 30 minutes but suddenly the write speed showing in the console window would go down to 0B/s (meaning basically nothing at all I suppose). I tried it 2 more times and it always came to a halt at the 10-20GB mark.
So this lead me to belief that that is also the problem while installing, that my drive doesn't want to wark anymore but rather just sleep a bit.What could be the problem? Is it a hardware error? Is there some linux system setting that could whip my HDD whenever it gets lazy? Did I do something else wrong?

I just installed Ubuntu 10.10. Everything works fine, except wireless. Wireless works fine for a while (I am right now using it) but then it loses all networks and I have to shutdown and then start Ubuntu again to get wireless network again.

my wireless will simply stop working after each new webpage loads. Whats strange is that it will not disconnect me, and the wireless icon in the top right will continue to show that I am connected to the internet. I am currently tethered to my phone and the internet is working fine. Once If I switch to my regular wireless internet and disonnect and reconnect to my home router then the webpage will load fine only once then after that it will not work again until I disconncet and reconnect again.
This is not a problem for anyone else in my house who all use macs (needless to say they are all very smug about this). Also when I connect to my schools wireless internet there is not a problem. Also restarting my modem and router at home does nothing to solve the problem. Like I said before this just started up about 3 days ago and has baffled me since.

I am trying to use sudo but it prompts that the password is wrong.
When I try to use gksudo everything is fine. I also can use su - without a problem.
I tried to add my user to sudoers and it seemed to work as you can see here:
Code: Select allronel : sudo root adm cdrom floppy audio dip video plugdev users netdev lpadmin
but it did not change the situation.

I'd like to be able to run gksu (i.e. the default windowed authentication) without a password. I tried to find this on the wiki and here on the forums but wasn't able to find anything. I've allowed 'sudo' to run without a password:
Code:
<username> ALL=NOPASSWD: ALL
for my username but this has no effect on 'gksu'. As I am the only user on my machine and I have to enter a password on login

System was running fine under 8.04 but decided to update. The live CD works fine but after install, the Mouse and Keyboard stop working under 9.10. Even the keyboard power button is off. Disconnecting and reconnecting the keyboard or the mouse does not . AMD Athlon 64 X2 3800+ PS/2 Keyboard and PS/2 mouse
Everything else seems OK but how would I know without the keyboard or mouse. The keyboard turns off right before the first Ubuntu screen. The Numlock will go off and then nothing. Tried to run dpkg - fix broken packages after booting to repair. All I get is fail to fetch http: (whatever )Could not resolve us.archive.ubuntu.com. Update: Alt-F3 ... then Booting to terminal mode does not disable the keyboard.

I have been working with Ubuntu for the last 6 months. Overall, I am all behind linux and open source. However, what I cannot figure out is why [in Ubuntu] or how can an app work for a while, then stop working within the same distro? My iPod was working great with HiPO, Banshee, and Rhythmbox and now, after the latest upgrade, it's not working.
