Description Evgeni Golov 2008-03-28 16:14:36 UTC 
Latest working kernel version: none
Earliest failing kernel version: 2.6.25-rc6
Distribution: Debian Sid
Hardware Environment: ThinkPad Z61m, ATI Mobility Radeon X1400, 15.2" 1680x1050 LCD
Problem Description:

I'm trying to get the native resolution (1680x1050) of my LCD running in the console. However, the maximum I can get is 1400x1050 (that is the maximum displayed by `hwinfo --vbe` and in /sys/devices/platform/uvesafb.0/vbe_modes). As the LCD supports 1680x1050 
(hwinfo says:
     Resolution: 1680x1050
     Horizontal: 1680 1712 1776 1904 (+32 +96 +224) -hsync
       Vertical: 1050 1051 1054 1066 (+1 +4 +16) -vsync
    Frequencies: 101.67 MHz, 53.40 kHz, 50.09 Hz
)
and I can get this resolution in Xorg, I wonder how one could get this in the console too.

Not a bug. uvesafb is limited to vesa modes, and 1680x1050 isn't a vesa mode. It'll need a native framebuffer driver to handle the full screen resolution.
