I did mean something else with "startup" - when kernel boots. I have thing, that in future xrandr will be obsolete and kernel takes the mode/dualhed setting job. Also e.g. how to set the graph. mode (like with vga=791 in past) with KMS ? BTW - I have try set mode on "text" console with fbset -v 640x480-60, but the screen was damaged and after try to switch to X console, the system (or maybe just keyboard/screen) hang. Is there some another tool to ask kernel to change video mode ? Or old procedures (like vga=..., fbset, xrandr, ...) have just new "internals" - calling kernel KMS routines ? -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ xorg-driver-ati mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-driver-ati
