Description Vadim V. Galitsyn 2005-10-18 23:56:19 UTC 
Most recent kernel where this bug did not occur: 2.6.13.3
Distribution: Slackware 10.2
Hardware Environment: Matrox Millenium G200
Problem Description:

Matrox framebuffer failed to start.

Module insert in rc.modules script:
 /sbin/modprobe matroxfb_base xres=800 yres=600 upper=21 lower=1 vslen=3 left=160 right=16 
hslen=80 pixclock=20203 depth=24
 /sbin/modprobe fbcon
 /sbin/modprobe mga

Logs looks like ok, but framebuffer console failed to display anything. This works ok with 2.6.13.3 
kernel, but fails in 2.6.13.4
Comment 1 Antonino Daplas 2005-10-19 03:47:39 UTC 
No changes in the framebuffer layer from 2.6.14.3 to 2.6.14.4.

Anyway, can you post your dmesg, cat /proc/fb, and fbset -i?

cat cat_proc_fb:

There is no bug. I've just forget to compile framebuffer console support.
