=== ATI Mobility Radeon X1400 ===
This is an ATI video adapter.

=== Features ===
* Chipset: ATI M54
* PCI ID: 1002:7145
* PCI Express x16
* 128MB GDDR1 video memory

==== ThinkPad LCD ====
Display on the internal LCD works as long as you set the monitor settings correct.

=== Proprietary ATI driver ===
Proprietary [[fglrx]] driver version 8.24.8 adds support for the x1400 chipset (according to ATI changelog). It works, including dualhead, 3d and video (XV) acceleration, when using the fglrx kernel module. (Without it, you get screen corruption including underlined mouse pointers.)

Sample "Device" section for xorg.conf:

Section "Device"
Identifier "ATI Graphics Adapter 0"
Driver "fglrx"
Option "ForceMonitors" "lvds,crt1"
Option "Centermode" "off"
Option "VideoOverlay" "on"
Option "OpenGLOverlay" "off"
Option "OverlayOnCRTC2" "0"
Option "PseudoColorVisuals" "off"
Option "HSync2" "31-64"
Option "VRefresh2" "56-75"
Option "UseFastTLS" "off"
Option "Mode2" "1280x1024,1024x768,800x600,640x480"
BusID "PCI:1:0:0"
EndSection

The kernel module doesn't work out of the box with the 2.6.16 kernel, you get undefined symbols such as module_get_request when inserting the module. The following patch to firegl_public.c fixes it (from http://www.stanchina.net/~flavio/debian/fglrx-archive/msg01158.html ):

XVideo support using the VideoOverlay option may not work with recent drivers. With version 8.29.6 of the fglrx driver, you can instead use

Option "TexturedVideo" "on"

Use the '''xvinfo''' utility to verify if XVideo support is available.

=== Linux kernel Framebuffer driver ===
Works with the VESA driver at 1280x1024 (you have to append {{bootparm|vga|794}} to the kernel boot parameters)

=== ThinkPads this chip may be found in ===

PS/2 Port

The PS/2 port is a 6-pin Female Mini-DIN connector, named after the IBM PS/2 (Personal System/2) computers that first featured it.

There are 3 different versions of the port found on ThinkPads and the Docks and Port Replicators:
* PS/2 Mouse
* PS/2 Keyboard
* PS/2 Mouse with PS/2 Keyboard (requires a PS/2 splitter cable for the keyboard)

Older ThinkPads typically feature the combined PS/2 port, meaning you need the special PS/2 splitter cable to directly attach a PS/2 Keyboard.<br>
On Docks and Port replicators you can either find the combined port, or two individual ports for Keyboard and Mouse.

Current ThinkPads no longer have a physical PS/2 port, but still have the logic integrated, all that is required is to attach the ThinkPad to a supported Dock or Port Replicator with a PS/2 port.

Problem with lm-sensors

2007-01-28T00:11:01Z

1169942176:

Information about the problem of lm_sensors corrupting the eeprom of Thinkpads.

==Problem description==
lm_sensors prior to 2.6.5 caused the corruption of the Thinkpad's [[AT24RF08]] EEPROM, leading to the Thinkpad not being bootable anymore.
The common error on the affected models was:
POST ERROR 188 - EEPROM CRC ERROR
or for the Thinkpad {{240}}:
0188: Invalid RFID Serialization Area

Also affected is glms (GNOME LM-Sensors).

{{NOTE|lm_sensors doesn't work with ThinkPads at all - even if this problem wouldn't occur. So just don't care about lm_sensors and use [[ibm-acpi]] if possible.}}

==Affected Models==

*Thinkpad {{570E}}
*Thinkpad {{600E}}, {{600X}}
*Thinkpad {{770X}}, {{770Z}}
*Thinkpad {{240}}
*Thinkpad {{X20}}
*probably more

==Affected Operating Systems==

*Linux, all flavours

==Status==
It is known that the corruption was caused during the execution of sensors-detect and it is also known that it is the specific Atmel [[AT24RF08|24RF08]] eeprom that is affected.

Hence the developers of lm_sensors included a Thinkpad detection routine into the software starting from 2.6.5 and published [http://www2.lm-sensors.nu/~lm78/cvs/browse.cgi/lm_sensors2/README.thinkpad this readme]. If you try to run sensors-detect on a Thinkpad it just quits with an error message, protecting your Thinkpads eeprom.

However, even though even the inner workings that cause the eeprom to get corrupted seem to be known, it seems impossible to avoid it and make lm_sensors work at the same time.

Currently it is unclear if newer Thinkpad models are affected or not.

==Solutions==

Use [[ibm-acpi]] to gather information about processor temperature and the like. All the interesting Thinkpad I2C buses are not accessible to the host CPU, anyway. The embedded controller takes care of them.

{{WARN|In any case, '''avoid lm_sensors and related software!'''}}
