Hi,

i followed the fbsplash-tutorial on gentoo-wiki.com and everything is working fine for 1024x768 themes. but I have a 19" LCD here and i want fbsplash to work in the native resolution of the display, which is 1280x1024. my monitor gives me an error-message that runs like:

signal error:
fH: 46.4 kHz
fV: 43.4Hz (this number is red and constantly blinking)

x is working fine on 1280x1024, it's just the fbsplash'd console, that somehow sets the monitor to the wrong settings.

i tried different combinations on depth and frequency in the grub-configuration (1280x1024-16@75, 1280x1024-24@60, etc ...) - nothing works. as soon as kdm is taking over, i see the login-screen and everything is fine. switching consoles with ctrl-alt-Fx shows the same problem again. X fine, console bad. :(

does someone have an idea on what to look out for?

thanks in advance.

this is what lspci has to say on my vga-controller:
ATI Technologies Inc Rage 128 Pro Ultra TF (prog-if 00 [VGA])
Subsystem: ATI Technologies Inc Rage Fury Pro/Xpert 2000 Pro

*edit*
as you can guess, that old card doesn't have a DVI connector. i use an analogue cable.

Which framebuffer driver are you using? I use vesa-tng and it has parameters that you can pass to it to set the max frequencies and pixelclock. Here are the options I use as an example:
Code:
video=vesafb:1024x768-16@75,mtrr:3,noedid,maxhf:69,maxvf:85,maxclk:350

That is one of the options on my kernel line in grub.conf by the way.

thanks for you input.

i do use vesa-tng, but unfortunately these options don't solve the problem. :(

this is the spec for my monitor:
http://www.eizo.com/products/lcd/s1931_21/spec.asp

so my grub line now contains:
Code:

... video=vesafb:1280x1024-16@75,mtrr:0,ywrap,maxhf:80,maxvf:75,maxclk:135 ...


and still my monitor shows me that fV: 43.4Hz error :(

i also tried mtrr:2 - no change ...
