637 * implementing the latest modesetting framework like done in the Intel
638 * driver is more than a few lines of patch, the randr-1.2 branch in its
639 * current form cannot the mode switching in a perfect way right now.
641 * As there are effors to bring modesetting into the kernel, controlled
642 * thru the drm module, of which nouveu currently requires its own version,
643 * one could even try to go one step further and try to bring the nouveau
644 * modesetting into the nouveau kernel module.c (as a first step which does
645 * not require a kernel patch), which would increase the chances that the
646 * text console is properly restored after X dies as the kernel can simply
647 * restore the text console when the process which has changed modes thru
648 * /dev/drm has been disconnected from the device.
650 * The current implementation simply tries to set each crtc to the mode
651 * for which the application asks for, hoping that one of them gives a
652 * usable monitor display (no error handling implemented), and sets
653 * the viewport of each crtc to (0,0), which means essentially clone
654 * mode with all monitors which managed to switch to the mode showing
655 * top left area of the framebuffer memory if the application's window
656 * is there. This is essentially what the Intel driver did in earlyer
657 * versions. To restore a LeftOf/RightOf layout, you two randr calls
658 * seem to be neccessary, one which sets the reversed layout, followed
659 * by one which sets the desired layout:
661 * xrandr --output Digital-1 --left-of Digital-0
662 * xrandr --output Digital-0 --left-of Digital-1
664 * FIXME: This could be fixed by getting the current viewports for the
665 * CRTCs and use these during mode settings, or (preferably) by getting
666 * the current screen layout and adapting the new viewports so that
667 * a new, continuos screen layout with the same monitor arrangement,
668 * but in the new mode is set up.
