Unfortunatelly it's not an option to change the distro or the video card, i have to use it :/ But I found the solution for that. There is an option for panel size: <div><br></div><div><meta http-equiv="content-type" content="text/html; charset=utf-8"><dt style="font-family: 'Times New Roman'; font-size: medium; "> <b>Option "PanelSize" "</b><i>width</i><b>x</b><i>height</i><b>"</b></dt><dd style="font-family: 'Times New Roman'; font-size: medium; ">Override LCD panel dimension autodetection.</dd><div><br> </div><div>found here:</div><div><meta http-equiv="content-type" content="text/html; charset=utf-8"><a href="http://www.x.org/archive/X11R7.5/doc/man/man4/siliconmotion.4.html">http://www.x.org/archive/X11R7.5/doc/man/man4/siliconmotion.4.html</a></div> <div><br></div><div>It fixed my problem, and now it works fine. But i got another problem, I need to replicate this multi-seat solution for this hardware, annd in every machine it gives me a different problem. In one of them its black-and-white and very wrong resolution, in the other there is no image, just a lot of colored stripes in the whole screen. They all have the same distro installed, the same moba and the same external video card. </div> <div><br></div><div>Fixing the DeviceInput section, shouldn't the same config files work for all of them ?</div><div><br></div><div>Thank you</div><div>[ ]'s</div><div><br><div class="gmail_quote">2011/11/30 Jeremy Huddleston <span dir="ltr"><<a href="mailto:jeremyhu@apple.com">jeremyhu@apple.com</a>></span><br> <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">You might have better luck with a better supported video card... that is to say that nobody has significantly touched the siliconmotion driver in a few years.<br> <br> You're also on an almost 2 year old distro and 2 year old X server release...<br> <div><div></div><div class="h5"><br> On Nov 29, 2011, at 6:41 AM, Caio Ricci wrote:<br> <br> > Hello,<br> ><br> > I am trying to set a multi-seat station under Kubuntu 10.04, so i'm<br> > starting from the basics, starting two separate X servers in a station<br> > with two videocards.
