Ubuntu :: Disabling Nolisten Tcp In 11.04 Gdm/X?
May 10, 2011
I upgraded a working Ubuntu system that I'd previously configured to accept tcp connections for the X server, which it's magically gone and added back in again. I can't now figure out how to disable it.
I've edited /etc/gdm/gdm.schemas and changed DisallowTCP to false. I've edited /etc/X11/xinit/xserverrc and removed the nolisten tcp line, but it still comes up with it.
The System->Administration->Login Screen has no option for security (pretty sure that's how I fixed it last time).

I have the following problem with Xserver which I think can be solved by starting it without the -nolisten option:
Server - (say 192.168.1.1) has the X application installed
Client - (say 192.168.1.2) is a stock standard ubuntu 11.04 client machine with screen and xserver installed.
I need to be able to run the X application on the ubuntu client by exporting the display on the server as follows:
Code:
export DISPLAY=192.168.1.2:0.0
xeyes
I have run 'xhost +' on the ubuntu client to disable access control however I still get the error:
Code:
Error: Can't open display: 192.168.1.2:0.0
I believe this is because xserver is started with the -nolisten option:
Code:
ps -ef | grep listen
root 1020 989 1 18:21 tty7 00:00:27 /usr/bin/X :0 -nr -verbose -auth /var/run/gdm/auth-for-gdm-V9E9KA/database -nolisten tcp vt7
Both server and client are not connected to the outside world and are in a trusted environment so security is not a concern (I realise doing the above is a serious security issue)
I cannot use ssh tunneling for the xserver traffic as the proprietory program relies on the DISPLAY variable been set to the correct client ip. (Would be great if I could though!!)
I have searched the /etc directory for the -nolisten option and have found the following file: /etc/X11/xinit/xserverrc. I removed the -nolisten tcp option however the xserver still starts with the -nolisten tcp option.
I have been looking through the xserver manuals however cant find too much relating to this.
Does anyone have any pointers as to how i could start the xserver without the -nolisten option?

I just installed the netbook remix 10.10 on my laptop. I have been using Unity and I would much rather prefer a standard GNOME desktop. I know there was a way to change the netbook interface to a standard GNOME one on the 8.04 remix. Anyone know if there's a way to do it in 10.10?

I have a faulty touchpad on a laptop (asus 1001) and want to completely disable it (using the machine with a mouse) - how do I do it? I can see that you can disable the touchpad for a couple of seconds but I want to switch the whole thing off.

I have disabled the screensaver from locking the computer and asking for a password. I did this by unchecking the box in System > Preferences > Screensaver which says 'Lock screen when screensaver is active.'
However, the screensaver still locks the screen.
I'm running Ubuntu 10.10 64-bit on an HP Pavilion dv5.

I'm running into some weird behavior while using xinput to disable the keyboard that might be an underlying bug, and I'm wondering if anyone could reproduce it or provide any insight into what's causing it. I'm running Ubuntu desktop 10.10 64-bit in a VMware Workstation VM running on a Windows 7 64-bit host.First I use "xinput list" to find out which keyboards are present in the system. In my case there's only one with id=9. Next I execute "xinput set-prop 9 "Device Enabled" 0" to disable the keyboard at id=9. Now, if I type this into the terminal and hit enter, the keyboard gets disabled but at the same time the enter key becomes stuck. The system thinks the enter key is being held down.
However, if I make a script with the same command and execute it by clicking it in Nautilus, the keyboard gets disabled and no keys are stuck. It seems if the keyboard is disabled with a press of the keyboard, then whatever key was pressed to trigger the disabling of the keyboard becomes stuck.
You might ask why I would want to disable the keyboard in the first place. It's because I'm running Ubuntu in VMware Unity mode, where the system in the VM is integrated with the host desktop system, the VM's windows appear as individual windows on the host desktop,etc. In this mode, whenever I close a VM window by hitting a key on the keyboard (for example, hitting Ctrl+D while in gnome-terminal) and focus goes back to a host window, then that key becomes stuck the next time I open a VM window. If I close a VM window by clicking the mouse then there's no problem. I'm pretty sure now that this is caused by the above mentioned bug from disabling the keyboard. I think in Unity mode VMware workstation runs a script to disable the keyboard in the guest whenever VM windows lose focus, so key presses don't continue to be piped to the guest OS. However, if this action is triggered by a press of the keyboard, then that key becomes stuck in the guest OS.

I am having a problem using my laptop's special keys to toggle my touchpad on and off on my ASUS G73JH laptop, running Ubuntu 10.10 (2.6.35-28-generic-pae).
First, some preliminaries:
My touchpad works just fine, but it does not respond to my laptop's special key, Fn+F9.
In /etc/acpi/events I have the following script, "asus-touchpad":
Code:
# /etc/acpi/events/asus-touchpad
# This is called when the user presses the touchpad button and calls
# /etc/acpi/asus-touchpad.sh for further processing.
[Code].....

I've just upgraded to 11.04, but Unity is unfortunately not my cup of tea. I use the classic desktop but I cannot find a way to disable a certain graphical desktop effect... I'm thinking of how the current workspace quickly slides into the next when I choose a different workspace.
If my recollection is correct, you could turn effects like that off in 10.10. This makes me dizzy, does any of know how to turn this off?

I can't figure out how to prevent Zend Server starting at boot up. My temporary solution is to issue the following after boot-up:
Code:
sudo /usr/local/zend/bin/zendctl.sh stop
I'd like to:
1. Prevent it from starting during boot
2. Create two launcher icons to Start and Stop Zend Server

For now I have just been unselecting it when I update everything else but I know myself and one day I will forgot to uncheck it and then I will be recompiling my kernel again.

This is the Linux version of my Disabling mouse acceleration in Mac OS X question. Hopefully I'll get an answer this time.I am tired of mouse acceleration and want to have a completely linear mouse response. This is easily achievable through any of the 5 or so methods (some subtly implied) on the X.Org wiki page on pointer acceleration. However, they also disable velocity scaling.I don't want a 1:1 mapping between device and screen coordinates. I want a 1:N mapping where N is a constant.

I have a headless Ubuntu computer which is primarily use as a server but which has Ubuntu desktop edition installed. I use X forwarding through SSH occasionally to use GUI programs so I am not looking to remove them. However, I would like to disable any GUI elements that would be started automatically when the computer is booted. Is the graphical login screen the only thing that would be run? or is nautilus, gnome-session etc. started as well? How would I go about removing the necessary entries from the init scripts?

I enabled auto-login on my netbook without considering that my /home partition is encrypted, so now I can't log in. Is there any way I can disable auto-login without using the GUI?EDIT:I was able to get around this by going to a TTY, logging in, then killing X and starting GDM again. Still, this is not acceptable. Subscribe to the bug here, if you agree with me.

It is extremely load and aggravating. My version 9.10. I am have no other issues with the internal speaker besides the low power beep. I have tried: blacklist pcspkr in /etc/modprobe.d/blacklist.conf (actually was already done in 9.10) in gconf-editor gone to apps gnome-power manager, unchecked low power notification
gone to sound preferences muted alert volume. If this was a desktop i would just physically disable the internal speaker, but i don't want to open up my laptop do to possible difficulty of reassembly.

I administer a desktop computer with ubuntu 8.04 in an university library. Since it works almost all night, to enable students to study, after some time I noticed some misuses of the computer during the evening, when there isn't many students. My goal was to disable users from accessing internet from 7pm to 7am, but also enable it if certain user was logged in (I use that user for torrent, and I seed on that computers from time to time). So I created a script that's being called by root's crontab, and here is the script's code:
Code:
#!/bin/bash
NUM=`who|grep myuser|wc -l`
#echo $NUM
if [ $NUM -le 0 ]; then
/sbin/ifconfig eth0 down
else
/sbin/ifconfig eth0 up
fi
Since I created the script, I actually never seeded anything, so I'm wondering now if that's going to work at all, and (also) is there a better solution for this.

I have an external WD hard drive on which I have created several partitions to facilitate data arrangement. Whenever I plug it in, all partitions are mounted. That is okay. I want it to automount all partitions. But the annoying thing is all partitions opening and popping up and cluttering my desktop (which I, very dearly, keep very arranged and clean...)
I hate it and want to edit the settings so the folders will not automatically open and pop up into my face..

I am trying to install Ubuntu 10.04 in text mode on a VIA EPIA-M motherboard with VT8623 VGA that gives a distorted screen when using the framebuffer. I used to be able to disable the framebuffer during installation by passing debian-installer/framebuffer=false to the kernel, and the screen would be fine. However, with Ubuntu 10.04, I still get a distorted screen even with debian-installer/framebuffer=false.

I installed the PinguyOS version of Maverick, but even after disabling all the repositories that came with it I still couldn't get this to work. Therefore this must be a problem with Ubuntu 10.10 itself, however if this problem does exist is Ubuntu, I'm surprised these forums are flooded with complaints. I've searched them up and down and I found nothing. Anyway, the problem is that I can't install digikam, this is the error I get: The following packages have unmet dependencies.
digikam : Depends: kdebase-runtime but it is not going to be installed
Depends: kdepim-runtime but it is not going to be installed
Depends: libkde3support4 (>= 4:4.4.4) but it is not going to be installed
Depends: libqt4-qt3support (>= 4:4.5.3) but it is not going to be installed
Recommends: kipi-plugins but it is not going to be installed
E: Broken packages
The problem here seems to be that the kde libraries that come with ubuntu are version 4.5 for everything. And it seems digikam 1.4 is built against kde 4.4.

I have used many other distros and just recently started using the Debian based distro Ubuntu. I am used to disabling services using chkconfig. I read this article on how to disable services using
PHP Code:
update-rc.d -f proftpd remove
to disable features but how does one list the services that are running via the CLI like with my CentOS box I run chkconfig --list |grep n and that will show me all that is running on all services so how does one do this with Debian or Ubuntu?
