I have an ASUS L7300 laptop with an SMI Lynx 910 vga card. I installed Piglet on this laptop (BTW, the graphical installation did not work). I configured the XF86_SVGA server as recommended. If I try to startx KDE (or login via GDM), the display will go blank and the keyboard does no longer react to any input. I can still login remotely and everything seems quite normal. The XServer and all KDE parts are up and running. I can stop and restart them but display and keyboard will stay dead. There are no problems when I use the XF86_FB server instead.
Another cosmetic problem I just noticed: All icons in netscape are in black and white when I use the XF86_SVGA server. (This does not happen with the XF86_FB server).
use the FB server instead, that laptop is not officially supported.
