The X VESA servers use the BIOS for video mode control. I don't think that Linux's S3 wakeup code would take such a mode-change into account though, right? It looks like saved_video_mode gets latched on bootup and is never subsequently changed. As you say, it looks like the right thing to do in most cases is not touch the video bios at all on wakeup. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
