Here is what I try to do : I got to modify the standard colors used by setterm, the reason being my preference for using text consoles rather than xterms. I also prefer the fg green bg black setup. I can acheave that just by simply issuing a "setterm -foreground green -store". Now my problem is that the green I get is too dark on my screeen (even if I set the display luminosity to max). If I could modify the color used by setterm I could get a bit brighter green, but I'm not sure where/how to do that... I've been looking in the kernel sources in the "console.c" and I think spotted the place where the colours are set but it seems to me that a more appropiate place to do such things would be the terminfo db. Any hints ? I'm using radeonfb under Suse/amd64 if that makes any difference... Rgds Thomas ^ permalink raw reply [flat|nested] 7+ messages in thread

However, there's one major flaw - programs recently (and by that I mean FC2-like recently) have started to do complete console resets, which result in the users settings being completely wiped out. For instance, I have: if [ "$TERM" = "linux" ]; then echo -ne '\e]P3aaaa00' fi in the bash login scripts. Run mutt 1.4 and that gets wiped out. Previous version of mutt (1.2?) didn't do this. So, in essence, this is a completely useless solution. I think we need a separate escape sequence to modify the system default so that peoples preferences do not get inadvertently wiped out by programs.

Why not add an escape sequence to lock/unlock the palette ?

I prefer "purified" colors, i.e. {0x00,0x00,0xFF} instead of {0x55,0x55,0xFF} for brightblue. :D >> However, there's one major flaw - programs recently (and by that I mean >> FC2-like recently) have started to do complete console resets, which >> result in the users settings being completely wiped out. >> So, in essence, this is a completely useless solution.

Yep, I've seen those problems too. OTOH probably its userland programs that should be fixed not to reset terminals? Pavel -- Thanks, Sharp! ^ permalink raw reply [flat|nested] 7+ messages in thread
