[Bug 27922] New: setting graphics mode for text console with video= instead of vga= does not work
https://bugzilla.kernel.org/show_bug.cgi?id=27922
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.

--- Comment #1 from Felix Miata mrmazda@earthlink.net 2011-03-08 00:16:11 --- 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.

--- Comment #2 from Elmar Stellnberger estellnb@gmail.com 2012-03-03 16:10:57 --- 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).

--- Comment #3 from Jérôme Glisse glisse@freedesktop.org 2012-03-05 16:56:01 --- 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.
