Notes and recipes

Suspend and hibernate

On Gutsy and Hardy, getting hibernation and suspend to work requires modifying /etc/default/acpi-support to have POST_VIDEO=false and SAVE_VBE_STATE=false. If proprietary NVIDIA drivers are in use, it additionally requires adding Option "NvAGP" "1" to xorg.conf in the Device section.

In Intrepid, I had some problems with the computer not coming back from hibernate. Sometimes it does and sometimes it doesn't - I haven't identified the cause yet.

Graphics

NVIDIA binary drivers version 96 is required to enable hardware acceleration, external monitor output and Compiz effects. On Gutsy and Hardy it had to be installed using Envy to get the recent version, on Intrepid it works after installing with Hardware Drivers. External screen works whe configured in xorg.conf i Gutsy and Hardy, not tested in Intrepid.

Beginning with Intrepid, the backlight is only turned off on battery. I think there should be some way to specify the DPMS blanking method.

Tablet buttons

In Gutsy and Hardy, keyboard configuration requires a lot of fumbling with xorg.conf to get the keymaps right for the tablet buttons and the external keyboard. Sometimes the mouse buttons on the detachable keyboard had wrong mapping (1 and 2 instead of 1 and 3). On Intrepid everything works correctly without any config.

There are 3 stylus-activated buttons which are reported through the digitizer's serial port as special packets of the form C0 0n 00 00 00 00 00 00 00, where n may be 1, 2 or 4. There's a patch (written by me) for wacom-tools on the LinuxQuestions wiki and on Linux Wacom Project's mailing list that turns those buttons into muse buttons 30, 31 and 32 which can then be mapped to arbitrary actions using xbindkeys.

ACPI features

The module tc1100-wmi provides backlight and wireless control. The command echo 1 > /sys/devices/platform/tc1100-wmi/wireless turns the wireless card on, the same with 0 turns it off. Theoretically, cat /sys/devices/platform/tc1100-wmi/wireless should print 0 if the WiFi is off and 1 if it's on, but this doesn't work - 0 is always printed.

Card reader

The card reader is integrated into the PCMCIA bridge and requires a firmware load to work. Texas Instruments has not provided any documentation on this part of the chipset. There are reports on the Gentoo Wiki of people enabling the reader using custom drivers, but I didn't succeed.

Connectivity

The infrared port is supported by nsc-ircc; it requires enabling in the BIOS setup, otherwise it won't work. I have successfully transferred a file from an infrared-equipped mobile phone. Wireless card is Intel IPW2200 but other configurations might have different cards, including IPW2100 and Atheros cards. All of them should work out of the box. Bluetooth works without any configuration and I can browse a Bluetooth-enabled mobile phone using it.

Docking station

Docking station for this tablet is purely hardware-based and doesn't need any software support.
