Configure RedHat Linux Beta Severn for the TC1000

• Note that the beta kernel loads very slowly and will appear to hang during and after "Finding module dependencies."

ACPI: Make sure to install the acpi rpm from the iso, it is not installed by default. ACPI is compiled in modules that do not load by default, and must be explicitly loaded using modprobe. The myxinit script loads the modules ac, processor, button, battery and longrun. The ac and battery modules must be loaded to use the gnome battery monitor panel applet - it will crash if these are not loaded. Redhat did not compile the longrun module, but a compiled longrun.o is in the zip file. See here for how is was compiled without rebuilding the entire kernel. Install it by copying to /lib/modules/2.4.21-20.1.2024.2.1.nptl/kernel/arch/i386/kernel.  Make sure the user/group are both root, and set permissions to 722 then run /sbin/depmod.

• Using >echo 1>/proc/acpi/sleep only works if the longrun module is loaded. It wakes up when you jog the power button, but the system will be frozen until then. Unfortunately when the system wake up, the side buttons and jog dial do not. You will probably need to restart the wifi after sleeping.
• The default script in /etc/acpi/events shuts the system down if you jog the power button. You will probably want to remove this if you are planning on putting the system do sleep: when you use the power button to wake up the system, you will also be shutting it down. Do man acpid for information in writing scripts.
• Various methods of turning the screen off blank the screen but do not turn off the backlight.
• There is a longrun utility that can be installed from an iso rpm. This should be able to change the system from "economy" to "performance" mode. In addition to loading the longrun modules, you will also need to load the cpuid and msr modules. However, the longrun utility still does not work giving the error message "longrun: error reading /dev/cpu/0/cpuid: Invalid argument." Possibly the kernel needs to be compiled explicitly for crusoe for this utility to work. Certainly using the other arch/i386/kernel modules compiled with longrun.o does not help.

Wifi: Unpack the directory atmelwlandriver and make the module. Since the module is already compiled, you should be able to do make install as root. Copy ifcfg-eth1 to /etc/sysconfig/network-scripts and edit it to provide the wireless and tcpip options relevant to your setup. The driver works fine with WEP. Do not load eth1 during boot, since the wlan driver isn't yet loaded. If you /sbin/modprobe pcifvnet this will load the driver and bring up eth1. The script radioon does this, and is suitable for adding to toolbars.

• The atmel driver builds and loads, but apparently doesn't work with the 2.4.20 kernel.
• This is the 5-17-2003 version of the driver, because it was reported to work with the TC1000. Likely more recent versions do to. If you download a different version, make sure to change depmod in the Makefile to /sbin/depmod.
• >/sbin/ifdown eth1; /sbin/rmmod pcifvnet removes the pcifvnet module - but the radio light on the front panel remains on, so it probably doesn't turn the radio off.
  

• For obscure reasons if you create a script file #!/bin/bash; exec xvkbd and run the script (with &) from Xsetup_0 you will get the keyboard during login, but it will be gone when gnome is finished initializing.

1. Make sure you know how to use grub to boot into run level 3 in case you make a mistake.
2. Unpack the directory fpi2002-0.1 and make the module. This program is from Michael Rolig. Since the module is already compiled, you should be able to do make install as root.
3. Copy XFConfig.land, XFConfig.port, XFConfig.dual to /etc/X11.
4. Copy myxinit to /etc/init.d and make a symbolic link to it named S30myxinit in /etc/rc5.d. This makes it possible to choose the video mode at bootup by setting kernel parameters myorient=xvesa for the xvesa driver, myorient=port for the nv driver in portrait (sideways) orientation, myorient=dual to clone the lcd screen to the vga connection using the vesa driver. The default is to use XFConfig.land, which uses the nv driver in landscape mode. The myxinit script also loads the fpi2002 module, configures the serial port used by the pen, and loads the needed the acpi modules.
5. Make sure in /boot/grub/grub.conf to set the kernel parameter nogui or the pen won't work. You can look at the included grub.conf for a sample of how to set up grub properly.
6. Copy Xmodmap to .Xmodmap in your home directory. I have it set so the scroll wheel does page up and page down; you may wish to change this, and set other options found in Michael Rolig's xmodmaprc file. Note that the pen works differently than under Windows XP - under XP holding down the pen for a short time is equivalent to the right mouse button; under Linux, holding down the pen and clicking the pen button is equivalent to the right mouse button.
7. Copy tck1_drv.o to /usr/X11R6/lib/modules/input. This program is from Michael Rolig.
8. Copy Xvesa and runXvesa to /usr/X11R6/bin. The Xvesa file is from Matthew Allum, the scripts adapted from Jamey Hicks
9. For both files chown root:root, chmod 711, chmod u+s 
10. mv XFree86 to XFree86.sve
11. The script tab-switch-screen, which must be run as root (for example using sudo) will switch between portrait and landscape modes. If you are using the xvesa driver the switch is immediate. If you are using the nv drivers it will bring up the gnome logout screen. If you logout and log backin, the orientation will be switched. I suggest creating a button for it on a toolbar. If you are courageous, you can use the autologin feature and /usr/sbin/gdm-restart. This will speed things up and switch orientation without having to intervene. It will also kill any data you are working on if you forget to save first.

• The fpi2002 Makefile had to be tweaked a bit to get it to work on RH.
• I haven't been able to build the nvidia driver, and I cannot get the nv driver to support two heads. However, the vesa and Xvesa drivers nicely clone the lcd display to the vga - and the pen works fine in this mode.
• If you do not set the kernel parameter nogui Severn will by default load an Xwindows startup screen in the boot process before fpi2002 has loaded. This makes it impossible to configure /dev/ttyS0 later. If you want to keep the graphical boot, it should be possible to modify the script /etc/rc.init/rc.sysinit to load fpi2002 prior to the beginning of the graphical boot.
• If you are using xvesa you may switch modes by using the command line utility xrandr or the gnome applet grandr to switch video modes. Or you may use the provided script.
• Don't copy Rolig's XFConfig files - they do not work with RedHat installations. 
• In rolling your own configuration files to use with the nv drivers - make sure in portrait mode you turn off the xrandr extensions explicitly, and make sure that you puta reference to the pen driver in the ServerLayout section.
• Xvesa does not generate any events for any of the side-buttons or the scroll wheel, except that depressing the scroll wheel is equivalent to the enter key. Running xev shows that the three "pen" buttons generate from left to right the keydown/keyup events 121, 122 and 125. The CVS version of Xvesa may now support the mouse wheel, but this has not been tested.
• Also from xev, using nv/vesa with the tc1k driver scroll wheel left 134, right 135, down 36 (enter), escape button 133, tab button 132, Q button 131, "schedule" button 130, red ctrl-alt-del 107 (ctrl-alt-del), the three "pen" buttons do not generate any events, regardless of how the "KeyEvent" driver option is specified.
  
• Calibrating the pen in the BIOS has no effect whatsoever on the pen in Linux.
• The Xvesa driver is reported to be slow, but I haven't noticed this.
  

• The setup.h file needed some fixing to compile under Severn; the backend.c file was modified to support annotation, and the command line convention changed.
• There are two other gesture recognition programs, xstroke and xscribble, but I couldn't manage to build either of them.
