Replacing the panel suffices (no need to replace chasis). You might need a
new inverter as well that provides sufficient power to power on the screen.
Unfortunately:
sudo i2cdump -y 5 0x50

IPS is a technology for panels which provides good viewing angles and high
quality color reproduction:
https://en.wikipedia.org/wiki/IPS_panel
The following official 15" T60 panels are supported by Libreboot and are also
IPS:
LG-Philips LP150E05-A2K1 (1400x1050)
BOE-Hydis HV150UX1-100
Unfortunately I didn't keep the note on which panel I installed
Yeah, that's because I took it from the wrong computer! I'm reinstalling
Triquel on my T60 now. When it's done, I'll try again. (need weekend)
On my T60 it says LTN141P4-L02
It's a 14.1" and 1400x1050 pixels produced by Samsung
Nothing special, I assume?
Thanks.
Is it actually easier?
I am not sure about what and where the inverter is. Is it physically placed
in the chasis of the display or is it in the 'main chasis'?
Thanks.
I was just lucky to find one on a site for buying and selling used stuff. I
was double lucky as I was permitted to borrow the display to check its
compatibility. What I did was to open the chassis and check the maker and
product number and compare to the ones listed by libreboot.
I got hold on a T60 for installing Libreboot. It has a non-compatible display
but I have retrieved a compatible one.
Would it make the most sense to replace only the panel or the whole display,
including the frame/chassis (or what it is called)?
And most important: It works with libreboot, so I'm happy :-)
I don't know what an ISP panel is, but the one I have is probably rather
average. Nothing special. Except of course, it works with libreboot :-)
Thanks a lot. I might need that.
The inverter is the small board connected to the screen which provides
battery/wireless/sleep indicators.
If you managed to obtain an IPS panel you probably have one of the best
panels compatible with libreboot. This is only relevant for 15" T60.
Yeah it's the regular TN panel with poor viewing angles (colors are probably
pretty bad if you view it from the side). On the bright side, at least the
resolution is respectable.
I did it. After some consideration I decided to change the whole chubang. It
was very easy when first I figured out which screws to take out.
Thanks for your inputs.
It seems your monitor is LTD121EWVB. According to this website
http://www.thinkwiki.org/wiki/TFT_display
your monitor is a 12" X200 panel produced by TMD-Toshiba.
Her we go:
sudo i2cdump -y 2 0x50No size specified (using byte-data access)
0 1 2 3 4 5 6 7 8 9 a b c d e f0123456789abcdef

Incidentally, you can also get a panel upgrade for the X200 (AFFS/PVA
technology similar to IPS), see e.g. here:
https://github.com/bibanon/Coreboot-ThinkPads/wiki/ThinkPad-X200
Try to replace 5 by another number (for me 2 worked) such as these:
$ sudo i2cdump -y 0 0x50
$ sudo i2cdump -y 1 0x50
$ sudo i2cdump -y 2 0x50
$ sudo i2cdump -y 3 0x50
$ sudo i2cdump -y 4 0x50
To find out which panel you have without opening the laptop just install the
package i2c-tools then run:
$ sudo modprobe i2c-dev
$ sudo i2cdump -y 2 0x50
If it doesn't produce valid output replace 2 with some other number (this is
based on the guide which appears at the Libreboot website
Great! If I many enquire where did you get a compatible display from?
maybe if I post someone wise will help you.
that is basically why I am posting here.
