I think that the "nice high resolution" you see with GRML is presented by the |
| 36 |
framebuffer. You only get this once the kernel starts to load. Until then |
| 37 |
you get a very basic VGA screen, which the GRML may not show at all (in other |
| 38 |
words the first visual impression of a LiveCD may be the framebuffer console). |
| 39 |
|
| 40 |
With the latest versions CDs which use KMS (e.g. SystemrescueCD) the two |
| 41 |
stages VGA-->framebuffer are visible if I recall correctly. |
| 42 |
|
| 43 |
With regards to your own kernel, are you using KMS? If so, once the kernel |
| 44 |
starts loading the KMS will dictate what resolution you get. If this is too |
| 45 |
small to read (I think it will render the highest resolution possible) or you |
| 46 |
want to set some custom resolution for whatever reason, then add nomodeset to |
| 47 |
the kernel line in your grub.conf and also restore the vga=XXX line you had |
| 48 |
there previously. |
