Tested with ALT Linux Ark 5.0 and Debian Squeeze (testing).
Average time of work without plugged power adapter - 5.5 hours with middle brightness of screen and WiFi on.
For touchscreen can be used both X11 evdev driver and eGalax official binary drivers. If you cant use evdev driver (for example - you cannot remove deprecated HAL and use xorg.conf.d) you should use binary driver eGalax:
Drivers from eGalax includes some tools such as calibration. Installator is script and need /etc/X11/xorg.conf file.
This file can be generated by command:
Xorg -configure
This command will make configuration file for current hardware and will show full path to this file. This file must be moved to /etc/X11/xorg.conf After this operation install script for eGalax driver and tools can be runned. End step - comment strings in evdev configuration file in xorg.cond.d directory that makes tablet and touchscreen work with evdev driver for normal work of touchscreen (without fast click at up-left part of screen by touching to screen).
Also in case of eGalax driver need to comment section “evdev tablet catchhall” in /usr/share/X11/xorg.conf.d/10-evdev.conf or cursor will move to left-top corner automatically. For working touchscreen section “evdev touchscreen catchhall” must be active.
Very good tablet PC. But need to find good desktop environment for use this computer as tablet - for example need configuration for fast screen rotation and call screen keyboard. Debian GNU/Linux is best choice for this tablet PC. Also Windows 7 Satrter (pre-installed OS) is very bad for tablet PCs - too slow and have no good tools for using in tablet mode.
