munir's questions

I use TP-Link (TL-WN723N, ver:2.2) usb adapter to connect to a wifi internet using Windows 7. Its WEP encryption type network and using a security key i can connect to internet. But in Ubuntu 12.10 i can see the wifi network is available in the Network manager but every time i try to connect to it, it keeps asking for the security key over and over again. I am using the correct security key but it won't connect to the network !

Do i have to install the correct driver for it in Ubuntu? If it is how?

Its kind of confusing because the system shows that there is a wireless network available, configures the network as a WEP type so it seems like the adapter is working. But it wont connect to the internet.

I just installed 12.04 Alternate for the first time to give it a try using a USB stick burned with UnetBootIn.

It installed without a problem. But it booted into a tty1 console without booting into a GUI.

After logging into the tty1 console, I typed unity. It appeared that the system doesn't have unity desktop. How can it be solved? My installation didn't show any error.

Something worth mentioning:

1. During installation, I had to choose an option saying 'customize the system to your needs' something like that I don't remember correctly with options 'SSH server','Mail Server', 'Ubuntu Desktop',.....,'Manual selection of packages' etc. I chose 'Ubuntu Desktop'. I haven't encountered something like this in 11.04.

2. To do an installation of Alternate iso using UnetBootIn, i used '12.04_Hdmedia' option of that software and had to change file extension of .ude to .udeb in /pool/main/l/linux that i found in Alternate ubuntu cdrom detect to go around with the cdrom detection problem.

3. I have a 945G intel graphics.

I have a dial-up connection for the internet which works perfectly well in GNOME using DSL settings in which i provide username, password, ip, gateway, netmask etc.

But in KDE i cannot do anything. After having provided the necessary information i don't see any available connection of DSL in the system tray. I have provided tow screenshot to show what is happening.

the wired connection is shown. But for DSL there is no such thing that i could click on to start using the web.

you can see that there is a connection under the DSL tab but it is not available at the tray.

is it this bug:Bug #447241 ??

It was reported in 2009. Now it is 2011. After several releases of kubuntu the bug should be fixed by now.

my question is how can i bring the DSL connection in the tray and solve the issue ?

/Please don't suggest to install other network management tool because to solve the issue of internet connection, i need an internet connection to install other package rendering me in a recursive loop. And please don't suggest pppoeconf . It makes the wired connection unavailabe. If CLI works then why this GUI./

By default apt-get installs packages in the drive that the ubuntu installation resides on. But can i install a package other than the ubuntu partition ? If i can, how to do it ?

Hello I do not have internet connection at my home. So i use "apt-get --print-uris" to list the http's and take it to other PC with internet connection and use wget to download them. I am facing difficulty about how to list the http's that amarok will download from for the extra functionality (like mp3 codecs). KDE deamon is showing me that these packages are needed for extra functionality of amarok but i don't know how to list their http's.

"apt-get --print-uris upgrade" does not list http's need for amarok/reqonk.

After installing Kubuntu 10.10 the look and feel was awesome. The fonts looked beautiful. But after having a reboot the font style changed and looked very ugly. After that i gave it another install. The fonts looked beautiful again. But after installing a Gnome program (synaptic packagemanager) the font style changed again. I have taken some screenshots system settings -> font before and after the font style chaged but there were no change in the settings. this is immediately after installing Kubuntu.

the fonts look very healthy here after installing a gnome application or a reboot fonts got very thin and ugly. just compare the line in konsole , words in menu. there is no change in the system settings.

also compare the letters of system settings page. same settings. but different style !! what's wrong ? How can i bring back the font style that was immediately after installation?

Numlock turned on on boot-up

i wanted to get the keyboard Numlock on when starting the computer. To accomplish this i went to system settings -> input devices -> keyboard and in the section "Numlock on when kde starts" checked "Turn on".

But that is not lighting up the NumLocK at startup.

what is the right place to accomplish this ?

I want my Kubuntu to auto mount my hard disks at login without the need for password. I tried it through System settings -> removable media and checked "Enable automount removable media". But at the moment i log in Kdesudo asks for password for all the hard drive at once.

I want it without any password. How can i do that ?

I have installed Kubuntu 10.10. when i click leave-> logout the system turns into a black screen just like a dos screen rather than a graphical screen. Once there keyboard does not work. I have logged out but i have no idea how to login. I have to press the power button to turn the PC off and start again.

Why on earth is this happening ?

After a fresh installation of Ubuntu 10.10 I tried to install build-essential from the Ubuntu installation CD. I put the cd in the cdrom and in the software repositories i checked the box install from cd(Ubuntu 10.10 release Maverick Meerkat).

Then I reloaded the software repositories. The synaptic manager then tried to download some repository related files but failed to do so as i didn't have internet connection. Then I open a terminal and wrote sudo apt-get install build-essential. It prompted me if I want to install build essential y/N. I typed y but the terminal showed some errors and was not installed. I also tried to add the CD in the software repositories.

I clicked add and it prompted me to insert a CD while the CD was still inside the cdrom. I clicked "ok" then and it showed it could not find any cd. What is wrong?

There is a tool in ubuntu system -> administration -> Network Tools.

What is the KDE equivalent for this?

I use Netscan softwar to search the available computers with the shared items in microsoft windows. I could give it an IP address range and it retured the available IP address.

In ubuntu is there such a way to scan the network ?

I have installed Kubuntu 10.10 alongside windows 7. In kubuntu 10.10 i tried to connect to internet using the DSL connection tab in the networkmanger on the taskbar -> manage connection -> DSL. i gave the username, password, ip address(manually) etc. checked the box of "connect automatically". The system connection checkbox was grayed out so i could not do anything to it. Then i clicked apply. But the connection that had just created didn't appear in the available connections. As there was no connection named that i created using DSL tab i could not connect to internet.

I used to connect to internet using the same method in Ubuntu 's networkmanager.

Is this some kind of bug in kde's network manager ? how can i solve it ?
