Software :: Su - From VNC Session Doesn't Work But Works Ok When At The Terminal
Nov 18, 2009
When I connect to my workstation via Real VNC Viewer 4 to Xvnc running on the workstation, and running "su -" I get authentication failure as follows:
So, effectively I cannot su when connected via VNC.
But if I'm at my workstation, I can su just fine:
Nov 18 16:24:30 localhost su: pam_unix(su-l:session): session opened for user root by xyz(uid=500)
Interestingly enough, I cannot su to my own userid over vnc, i.e. su xyz
In /var/log/secure I get:
I suspect it has something to do with PAM, but cannot figure it out.

I've got 9.04 and 9.10 both installed on the same machine. The /home directory is on a separate partition, so both OSes use the same /home.I can't get Compiz to work at all in 9.10, even though it's been perfectly fine in 9.04. Is there a backport of some sort that i should install?The fixes I've found all point to editing the xorg.conf file, but of course, Karmic doesn't have an xorg.conf file.I've tried reinstalling the Compiz files, reinstalled the open-source video drivers, installed/uninstalled fglrx drivers a few times, rebooted dozens of times.

I am using Ubuntu 9.10..My sound works fine unless I have headphones plugged in. I've tried 2 sets of headphones, and it doesn't work with either set, so it's not the headphones. The volume is not muted (it's at 100%) for the headphones either in alsamixer. How can I diagnose and fix this?

I've recently installed KDE 4.4.1 just to try on a Dell 1545 laptop with Ubuntu 9.10 previously installed.
My problem is that the wireless connection works just perfectly with nm-applet under Gnome, but when I login on KDE and ask KNetworkManager to connect to the same network as before, it can't finish the connection.
When I choose the connection the program asks for my passphrase, I type it and then it just sticks on "activating network" and nothing happens.
My experience with KDE is zero, so I don't even know where to start looking. I'd even tried to kill KNetworkManager and try to replace it with nm-applet, but I think there's a daemon that restarts it immediately.

Ive been having some troubles with wireless. Ethernet works but wirless (at first) doesn't work. However, when i plug the ethernet in, all the wireless networks it detects are populated and i can then connect until i shutdown my computer.My disable internet button on my computer also doesn't seem to work well. It is always blue, and when i press it and have internet connection estabsliehd, it erratically turns from blue to orange to blue and then stays on blue.
When i have shutdown and booted up and i haven't placed ethernet in (so wireless doesn't work) it wont even change color.Any solutions? I dont know what info to include so just let me know and when the wireless does it work, it is slow in opening a new tab and connecting to google.

I recently moved from Ubuntu Desktop to Ubuntu Server. I have a Dell D600 acting as a three prong firewall. I use a Netgear FA120 USB NIC for the third prong. After converting to Server, the NIC detects as Eth1. I'm able to configure an IP, but the NIC never sends or receives packets. The same NIC works great in Ubuntu Desktop. Dmesg never shows the NIC being ready.

Works fine when I have the laptop plugged into the mains and will happily switch from 3.5mm to speakers and back again.
But for some reason, when the laptop is on battery I don't get any sound and all, from the 3.5mm or the speakers.

I have a sony laptop VGN FS315M, i recently installed Ubuntu 11.04, and i really love the unity interface.
But i have a few issues as well:
1. Vaio FS315M has Nvidia graphics card, ubuntu suggested a video card driver which i installed but didn't work well so i switched to the another one and it worked generally well but that too has problems like if my computer goes to sleep upon closure of lid, it cannot wake up again. it shows only a white screen and only way to get out of it is to restart the computer by manually pressing start button.
2. Sound card works generally ok but mic doesn't work on startup but when i click sound preferences and mic selection from analog microphone to another one and then again to analog microphone, it works but not the first time. Sound output is low compared to windows.
3. Arabic/persian fonts generally are not shown well in firefox?
4. Computer seems to be slow in unity compared to 10.10, may be because of high demand on graphics or the graphics card is not optimized?
5. Skype won't start automatically and there's no option in this skype to do so and also it doesn't save password?
6 . Ubuntu doesn't connect to net connection unless i connect manually, i want it to connect automatically to internet
7. This issue is not related directly to ubuntu. My system is a dual boot system with windows xp as well. Before windows xp, i tried windows 7 beta and then later removed it but it left its bootloader at startup. since my CDROM drive is also out of order so i tweaked BIOS by installing PLOP to install ubuntu. Now i have 3 startup menus if i want to run windows xp, one for ubuntu, then windows 7 with option for earlier version, when i select earlier version then windows xp or PLOP installer. so its a mess. I want PLOP to appear at the beginning (so that i can have boot option from USB available), then ubuntu and if i select windows it should go directly to xp not thru others.

I've been using ubuntu for months now and it was really frustrating dealing with hardware issues. Just when I thought everything's going ok, today, when I boot up, I am greeted by the following error: "Ubuntu is running in low-graphics mode your screen, graphics card, and input device settings could not be detected correctly, you will need to configure these yourself."
Selecting "run in low graphics mode for one session" doesn't work. It looks like it's loading something but nothing. I tried various options like "reconfigure X" and none of them works. I can login the console find though. I have a backup from a month ago but I've changed a lot since then.

I've been using Slackware for awhile now on my laptop without a single issue (well except that I can't get the screen brightness to change, but that's a separate issue).
I logged in today and went to the terminal and when I type the letter 'e' it is not shown or recognized. It works when I 'su -' and enter my root password which contains the letter 'e' twice, but otherwise is not recognized.
I have no idea where to even start with this problem. I've logged out and back in. I've restarted twice now, but the problem is not going away. Obviously, my keyboard is working properly as I am typing this message with the letter 'e', but in the Terminal it is not recognized.

I'm using 10.04, and gnome-terminal GNOME Terminal 2.30.2 . I have irssi running on screen session on remote host. And I've been struggling for quite many days to configure it to produce either visual feedback or ring terminal's bell when I receive a private message or one of those that are highlighted.
My compiz settings window in General tab has 'Audible bell' checked.
My GNOME terminal has 'Terminal bell' checked.
I also added 'set bell-style audible' to my ~/.inputrc
And I also tried to manually load pcspkr module into my kernel.
No of the above helped or at least I haven't been able to notice any difference.
I also used some commands for irssi to produce bell sign.

I am very new to this and tried searching for this problem in the forums but have not find anything. When I installed ubuntu (formatted HD), the installer gave an error but then seemed to proceed as normal and everything installed (from CD). However, when I boot up from Live CD all my wireless works fine (it detects networks, connects, etc.) When I boot up without the CD it says networking disabled and gives me no other options.

I installed freenx-0.7.3-i486-1alien.tgz on the server (with Slack 12.1), all according to instructions. I installed the no machine nxclient 3.4.0-7 on the client (with Slack 12.2). I ran setup and configured. I used the default no-machine keys, not custom ones. Since authentication failed at the beginning, I enabled DBauthentication, and added my user and password, which seemed to allow authentication to occur.
Here is my node.conf:
# node.conf
#
# This file is provided by FreeNX. It should be placed either into
# /etc/nxserver/node.conf (FreeNX style) or /usr/NX/etc/node.conf
# (NoMachine NX style).....

I installed nautilus-open-terminal, and now the option "Open in Terminal" does show up in the context menu for me in Nautilus, and clicking it does open a terminal. But it just opens to the home directory, every time, same as if I'd opened a terminal in the ordinary way. I've tried to look for solutions to this, but I can't find anyone that even has the same problem. Other people complaining about it all seem to be saying that a terminal doesn't even open for them, which is not the case for me.

System: Debian 7 Wheezy amd64 - Gnome classic - gdm3
I'm trying to create a new gdm session in tty8, so I can switch between tty7 and tty8 running simultaneously.
How can I accomplish this? I found some website suggesting to run startx and also startx gnome-session -- :1 vt8 Both result in a black screen, blocking the overall system, not allowing me to go to tty1 nor any tty. I have to run REINSUB to restart the system.
# I don't know if tty is the exact term to refer to the CTRL+ALT+Fx virtual terminals.

I need to close my session but the exit button is no longer here. I can restart the computer (ctrl+alt_del), but not only the session. I opened a session with the gnome desktop but everytime is messed up and I want to come back to the UNE desktop. How can I do that from a terminal?

when i did that, I turned it back on, and well I had this huge huge problem, i've made a few threads about it. So I had to go through a manual FSCK. I did all that and I do have the cd, although when I try to boot off of the live cd, it gives me a bunch of buffer errors, I have a thread or two about that problem too. So i can't boot off a live cd and fix it through that.
Now i've gotton to the point where I can get to the login screen, it looks normal and everything but when I log into a normal session it greets me with this Your session only lasted less than 10 seconds. If you have not logged out yourself, this could mean that there is some installation problem or that you may be out of diskspace. Try logging in with one of the failsafe sessions to see if you can fix this problem. View details (~/.xsession-errors file)
Code: /etc/gdm/Xsession: Beginning session setup... Setting IM through im-switch for locale=en_US. Start IM through /etc/X11/xinit/xinput.d/all_ALL linked to /etc/X11/xinit/xinput.d/default. mkdtemp: private socket dir: Permission denied
So i have no idea what that all means but i did understand failsafe terminal. So when I go to the failsafe terminal to try and fix things, I'm completely lost. I don't know what to type at all. I'm a windows user most of the time.

Is there a way (In the terminal or script file) to change the session during login? The login screen I have in Ubuntu 10-10 only allows for name and password, no other options. Is there a way to change the login screen? I downloaded some new login screens but don't know how to change the current gnome.desktop session to something else and I DON'T want to get stuck in another login "Twilight Zone"
