Linux Tablet FAQ

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"):

• RotateSideways.sh
• RotateNormal.sh

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/):

• rotate.sh

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?

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.

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.
