=== Ubuntu 7.10 /8.04 === You can Install Ubuntu in different Ways. Either use the CDRom in the docking Station or install from USB. As it's USB 1.1 it will take about 1,5h to complete. Use the alternate Disk. This cannot be stressed enough since 256MB are not enough to run the graphical installer. As default X-Server Ubuntu will use the Intel driver for X.org. This Driver fails with the Tablet and produces a white Screen, the i810 Driver works fine. ==== USB Install Instructions ==== Although it does not seem so, the tablet can boot from USB. You need to select "Boot from Optical Drive". Installing from USB is kind of tricky, as booting and installing did not work out of the box. I will add some instructions later, in general you need to use the "Install from ISO Image" Option in debian-installer. ==== Configuring X ==== ===== 4120P ===== After a lot of fiddling to get the touchscreen up and running this is my [[UbuntuHelp:attachment:xorg.conf|attachment:xorg.conf]], which is good for the 4120P I have. This is the source of the fpit driver which works for me. Download [[UbuntuHelp:attachment:xf86Fpit.c|attachment:xf86Fpit.c]], do a ''apt-get build-dep xserver-xorg-input-fpit && apt-get source xserver-xorg-input-fpit'' copy the downloaded source into the folder where the original source sits. Then do a ''configure && make'' and cross your fingers you should find the compiled '''fpit_drv.so''' in ''xserver-xorg-input-fpit-1.1.0/src/.libs'' copy it to ''/usr/lib/xorg/modules/input/'' I know this is really not nice but since this is such a niche driver I am happy it just works! Make sure to add the following line to ''/etc/serial.conf'' /dev/ttyS0 uart 16550A port 0x0220 irq 4 baud_base 115200 spd_normal skip_test ===== 4120W ===== The 4120W also has a serial touchscreen interface but manufactured by Wacom instead. The touchscreen works great under Hardy including right click. There is no need to create or edit /etc/serial.conf or recompile anything, but you do need to edit/replace your /etc/X11/xorg.conf to get both video and the touchscreen working. For the touchscreen you need to add XInput descriptors for the stylus, eraser, cursor, touch, and pad devices as detailed in the Linux Wacom docs: http://linuxwacom.sourceforge.net/index.php/howto/inputdev ==== Configuring WLan ==== As some devices contain a Prism2.5 WLan, you need to take the following steps to get WPA-PSK Working: '''''Attention: These steps make you flash your Wlan Hardware. I do not take any resposibility if it does not work. Use your brain from this point on!''''' The wireless chipset is a well known Intersil Prism 2.5. It supports WPA and WPA2 in Windows. However the hostap driver supports WPA/WPA2 on it only with a firmware update. [http://linux.junsun.net/intersil-prism/] is an excellent reference for this. Use hostap_diag wlan0, the firmware version is: NICID: id=0x8013 v1.0.0 (PRISM II (2.5) Mini-PCI (SST parallel flash)) PRIID: id=0x0015 v1.1.0 STAID: id=0x001f v1.4.1 (station firmware) Read the release ID table carefully in the hardware model information. I picked the stable firmware from Jun Sun's firmware collection: pk010101.hex rf010704.hex Flashing is done via the program '''prism2_srec''' The new firmware works like a charm and its version is: NICID: id=0x8013 v1.0.0 (PRISM II (2.5) Mini-PCI (SST parallel flash)) PRIID: id=0x0015 v1.1.1 STAID: id=0x001f v1.7.4 (station firmware) For the wpa_supplicant.conf, I followed this HowTo: [http://ubuntuforums.org/showthread.php?t=263136]. When in doubt, you can run the wpa_supplicant command manually and enable verbose output: sudo wpa_supplicant -Dwext -i wlan0 -c/etc/wpa_supplicant.conf Steps taken from: [http://offtopic.org/twiki/bin/view/Main/GadgetTabletST4110]
