           Summary: setting graphics mode for text console with video=
                    instead of vga= does not work
           Product: Drivers
           Version: 2.5
    Kernel Version: 2.6.38-0.0.7
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
        AssignedTo: drivers_video-dri@kernel-bugs.osdl.org
        ReportedBy: estellnb@gmail.com
        Regression: No


I have stated "video=1920x1200-24@60" on my kernel command line. Instead it
initializes a 80x25 text console with a low resolution of sth. like 640x480 or
so.

  The video kernel command line is said to be the future replacement of vga=
modes by the Xorg development team (vga= is said to be no more compatible with
Xorg`s video mode initialization). 

Is it already implemented?
If yes a fallback to a similar Vesa graphics mode with Vesa safe/restore mode
on vt-switch may be an additional opportunity.

occurs with and without kernel modesetting.

With radeon rv380 and a P275 Trinitron CRT, video=1024x768 on cmdline instead
of vga=0xwhatever or vga=7whatever works for me with default modesetting state
and Kulow/openSUSE kernel-desktop-2.6.37.2-3 and GA kernel-default-2.6.37.1-1.2
to produce same result on tty[1-6] as vga=791/vga=0x305/vga=0x317/vga=0x318 did
before KMS implementation.

  As far as I have tested it on my machine the radeon module needs to be loaded
with KMS enabled (no radeon.modeset=0 parameter) to get the video
kernel-cmdline option interpreted (/proc/cmdline). If you f.i. need to use
uvesafb instead give the following option: uvesafb.mode_option=1600x1200-24@60
(1920x1200 is no Vesa mode). The same parameters can be given on modeprobe
leaving the module name (radeon., uvesafb.) out
(/usr/src/linux-ver/Documentation/fb).

This is not a bug, video= command line is only interpreted with kernel
modesetting enabled. We don't support anymore non kernel modesetting case for
radeon.
