Lilo vga modes?
 
I have just installed new kernel 2.4.24, but I've lost the nice resolution on the character console. Now it boots at 80x25 text screen. What options should I give to lilo.conf in order to have the nice booting screen characters with the small penguin on the upper left side??

Try vga=769 or vga=788. 'vga=ask' will give you a list of choices.

"What options should I give to lilo.conf in order to have the nice booting screen characters with the small penguin on the upper left side??"

Set the vga= parameter to the VESA resolution that you want. The following vga numbers are all 256 colors which is plenty for the boot screen.

640x480 vga=769
800x600 vga=771
1024x768 vga=773
1280x1024 vga=775
1600x1200 vga=796

do u know where i can find all these settings? If i want to change the refresh rate in the console? Is that possible/?

"do u know where i can find all these settings?"


Here is the entire table. The reply script messed up the spacing a little but it is still readable.

The vga modes are:
hex:
| 640x480 800x600 1024x768 1280x1024
----+-------------------------------------
256 | 0x101 0x103 0x105 0x107
32k | 0x110 0x113 0x116 0x119
64k | 0x111 0x114 0x117 0x11A
16M | 0x112 0x115 0x118 0x11B

dec:
| 640x480 800x600 1024x768 1280x1024
----+-------------------------------------
256 | 257 259 261 263
32k | 272 275 278 281
64k | 273 276 279 282
16M | 274 277 280 283

VESA:
Colors (depth) 640x480 800x600 1024x768 1280x1024 1600x1200
---------------+-------+-------+--------+---------+---------
256 ( 8 bit)| 769 771 773 775 796
32,768 (15 bit)| 784 787 790 793 797
65,536 (16 bit)| 785 788 791 794 798
16.8M (24 bit)| 786 789 792 795 799

"If i want to change the refresh rate in the console? Is that possible/?"

You can change the refresh rate in X Window by changing /etc/XF86Config. I do not know if you can change the refresh rate for the command line other than the vga= parameter at boot.

How about: grep "|" /usr/src/linux/Documentation/fb/vesafb.txt

Akhran 11-13-2005 04:58 PM

I don't have vesafb.txt anywhere on my system.

You need the kernel source for that file. Did you try the svgamodes command?

Akhran 11-14-2005 07:02 AM

I don't have the svgamodes command anywhere in my system either...

Oops, sorry. The svgamodes comes from knoppix-kudzu on my kanotix sid install. Guess it's easiest to google the table unless you install a kernel source.
Anyway, here's what the first command returns:
~# grep "|" /usr/src/linux/Documentation/fb/vesafb.txt

does this work for grub too?

aaa 03-19-2006 10:57 PM

Yeah. It's a kernel thing, independent of the bootloader. As long as the bootloader can pass parameters to the kernel it should work.

vimalkumar.s 08-01-2006 07:07 AM

I to had the same problem and I solved it by adding vga = 769 in grub.config file
