 Posted: Sat May 14, 2005 4:11 pm Post subject: framebuffer refreshrate |
 |
|
Hello, i think i've tried almost about everything but still cant change the refresh rate of console framebuffer from 60hz.
Im running the system at 1280x1024 and im 100% sure that my monitor can handle 90hz in that resolution, but just to be sure im trying to make it run at 85hz.
My grub.conf
| Code: |
kernel /kernel-2.6.11-gentoo-r8 root=/dev/hda3 video=vesafb:ywrap,mtrr,1280x1024-32@85
|
Kernel is configured with "1280x1024@85" line at the framebuffer section.
The videocard is a Radeon 9800XT.
CPU: P4 3.0ghz
Any ideas? |

I had this problem too. I was able to work around it (cheating) by setting the refresh rate and resolution directly in the kernel config file:
Contents of .config:
| Code: |
#
# Graphics support
#
CONFIG_FB=y
CONFIG_FB_MODE_HELPERS=y
CONFIG_FB_TILEBLITTING=y
CONFIG_FB_VESA=y
CONFIG_FB_VESA_TNG=y
CONFIG_FB_VESA_DEFAULT_MODE="1024x768@85"

And this is what I have in grub.conf:
| Code: |
title=GentooLinux 2.6.11-r3
root (hd0,0)
kernel /kernel-2.6.11-gentoo-r3 root=/dev/ram0 init=/linuxrc ramdisk=8192 real_root=/dev/hdb3 udev
initrd /initrd-2.6.11-gentoo-r3
|
No vga mode passed to the kernel so it uses the default setting it was compiled with.
