Re: [lcd4linux] Text Overlay Problem

[Michael R. <re...@eu...>]

Hi James, Hi List,

[I'm cc:ing this to the list again, because I'd need some help from 
other CrystalFontz users]

you had this problem:

I Asked you for your lcd4linux.conf, here it is:

> Row5 "CPU Temp: %s1c"

I had to modify it a bit to meet the needs of my MatrixOrbital. But the 
problem does not arise here. Maybe because I don't have your 
"uptime.pl". Could you please provide this script, too?

herp [author of the crystalfontz driver], anywhere out there? Your email 
adress is invalid...

If all doesn't help, I'm afraid I have to rewrite the crystalfontz 
driver. It's the only driver not using the "general bar" functions. And 
I have to admit that I don't really understand herp's code here :-(


bye, Michael
