Ah.

Now it occurs to me to use UTF-8, so I shouldn't need the 8859 codes. Thus it becomes feasible to try removing the console-font service - thanks again. > In addition to setting vga=0x0133 for a normal 132x44 character console > (720x400 px), I /had/ been setting the consolefont to gr737c-8x6, giving > me an even higher resolution while still very readable, but I've disabled > that now, sticking with 132x44, so I can scrollback the entire boot when > necessary. I use vga=0x31A on this 19", 1600x1200 flat panel. If I run nvidia-drivers this gives me a screen of 160x 64, or if I use the nv kernel module I get 200x75. I find both of those legible, though the latter is getting a bit small - and of course all that screen redrawing takes time in a long emerge. -- Rgds Peter -- [email protected] mailing list
