Anyway, is it possible to get it working? I see that something is overwriting
LCD diagnostic info while loading Linux.
My Kernel is compiled with
CONFIG_CHASSIS_LCD_LED=y
Sure you know it. :-)
BR,

Depends on which gfx card you have driving the LCD. Of the few people that do have K-class, I doubt many have a gfx port. grant ^ permalink raw reply [flat|nested] 7+ messages in thread

I think Mihails talks about the small panel LCD display on the front of the chassis, which e.g. shows "Linux Version 2.5.xx" after boot. Or do I misunderstand something here ?

You're right, it's better to call it LCD panel. :-) I ask people having D, K, J classes if LCD panels should work. I see that panel normal is being overwritten with black rectangles while loading Linux. I hope my question is clear now. BR, Mihails P.S.

There you'll find a few "workarounds" for Kittyhawk machines and some explanation, why it maybe doesn't work. =46rom one of the comments: ** KittyHawk machines have often a buggy PDC, so that ** we explicitly check for those machines here. Maybe you try to change some coding there, else I'll try and continue=20 to figure out next week....

The Hardware-ID of your system might be interesting to figure out, why it doesn't work. Helge ^ permalink raw reply [flat|nested] 7+ messages in thread
