I was using locales to give me ISO-8859-1 and -15 character sets, but glibc |
17 |
is buggy in this area and I've had to keep recreating the locales with |
18 |
localedef. Now it occurs to me to use UTF-8, so I shouldn't need the 8859 |
19 |
codes. Thus it becomes feasible to try removing the console-font service - |

thanks again. |

I use vga=0x31A on this 19", 1600x1200 flat panel. If I run nvidia-drivers |
29 |
this gives me a screen of 160x 64, or if I use the nv kernel module I get |
30 |
200x75. I find both of those legible, though the latter is getting a bit |
31 |
small - and of course all that screen redrawing takes time in a long |
32 |
emerge. |
