The graphics adapter's resolution is set by selecting an option in BIOS but I would like to override it. Can kernel or Xorg do this? There are two modes "almost" right for an 800x600 16bit LVDS screen I have. The first one is 800x600 but in 24bit LVDS mode, so colors are mangled. The second one is 800x480 16bit -- colors are right, but the screen cuts the image at line 480. I've tried video=, overwriting modes via patched 915resolution, vga= and Xorg modesetting driver. Nothing works. Does anyone know if it's possible to override the mode? -- Marcin Szewczyk http://wodny.org mailto:Marcin.Szewczyk@wodny.borg <- remove b / usuĊ„ b xmpp:wodny@ubuntu.pl xmpp:wodny@jabster.pl -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
