Linux Tablet FAQ
How do I change my password under Linux?
In order to change your password under Linux you should open up a console window and type
sudo su passwd student
and follow the directions (make sure to place "student" after passwd so you do not change the root password). It is recommended that you change your password, failure to do so may result in an inability to restore your session if the display gets locked. The display will lock if you close the tablet while Linux is running in Gnome so you will need to change your password before this happens.
How do I connect to the VPN?
Click the network manager icon in the system tray (in the upper right hand corner). Go to VPN Connections -> Configure VPN. Click the CSM VPN, and click edit. Go to the optional tab, and make sure that the "Override user name" is selected, put in your AC&N username (your email without the @mines.edu at the end). Click apply, and again click the network manager icon. Go to VPN Connections -> CSM, the group password is "CSMRocks", and the normal password is your AC&N password. Then you can launch Mathematica without getting the license error.
Kile can't use spellcheck, help!?
We apologize that we did not get this into the existing build. You can add spell-check capabilities by installing the packages for spelling, this can be done from the command line by executing the following commands:
sudo su apt-get install aspell apt-get install aspell-en apt-get install ispell apt-get install myspell-en-us
Adding these libraries will also add spell-check capabilities to OpenOffice.org.
The tc4200 powers off very easily, is there a way to fix that?
YES! You can download a quick little script that (when installed) will ask you before powering down the system:
 Download Power Down Confirmation Script (Version 0.1)
|
Once you have downloaded the above file you should extract it and run the script "install.sh" contained in the folder powerbtn, this can be done from the command line by executing:
tar -xzf powerbtn.tgz cd powerbtn.sh ./install.sh
Mathematica crashes the GNOME panel when I launch it - how do I fix that?
Try running mathematica without the splash screen, you can do this by executing
mathematica -noSplashScreen &
at the command prompt.
How do I rotate the screen on the tc1100?
At a console (not as root), enter
xsetwacom set "stylus" Rotate CCW xrandr -o left
to rotate the screen side-ways and enter
xsetwacom set "stylus" Rotate None xrandr -o normal
to rotate the screen back. Once we've got the tablet hotkey buttons working these commands will be integrated into a script for you. Until then you can take advantage of these handy-dandy scripts by downloading them and adding them to your GNOME/KDE panel (please right click and use "Save File As"):
If you have downloaded the Modified Wacom Pen Driver then you can take advantage of the following script to automatically rotate the display on the tc1100 (place in /usr/custom/bin/):
I'm having trouble making first-time connections to wireless networks under Linux, what should I do?
There appears to be a problem with the wifi-radar software in that it cannot connect to wireless networks that you have not connected to before. While the wifi-radar software is in the "working" stage open up a console and type
sudo su ifdown eth1 ifup eth1 kill `ps -A | grep wifi-radar`
in order to reset the wireless network connection. If you continue to have problems please leave a message on the Forum.
How can I setup my tablet to connect to a WPA-enabled network under Linux?
Preferred Method
This method requires that Ubuntu Dapper be installed and updated
The experimental version of NetworkManager can be used to support WPA and WPA2 networks under Linux. In order to do this you must add the address for the experimental NetworkManager to your package list, this can be done by adding the following lines to /etc/apt/sources.list:
# NetworkManager Sources deb http://kubuntu.no-ip.org/kubuntu dapper main deb-src http://kubuntu.no-ip.org/kubuntu dapper main
Once you've added those lines you need to update the local package list and install the new NetworkManager, this can be done by executing the following lines from the command prompt:
sudo sux wget -q -O- http://kubuntu.no-ip.org/AnthonyMercatante.gpg | sudo apt-key add - apt-get update apt-get install network-manager nm-applet
Please understand that this will place your NetworkManager into a state where it will be more difficult to update in the future, in order to update you will likely need to remove the lines that were added to /etc/apt/sources.list and you may need to completely remove the "network-manager" and "nm-applet" packages and re-install them in order to bring your installation back in-line with the experimental tree.
See Dapper NetworkManager for details.
Universal Method
You need to edit the "/etc/wpa_supplicant.conf" file to contain:
ctrl_interface=/var/run/wpa_supplicant
network={
ssid="<your_network_name>"
scan_ssid=1
proto=WPA
key_mgmt=WPA-PSK
psk="<your_secret_key>"
}
See Amilo 1425 Linux for details.
