Not sure how much it relates, but I've a trident 9382 + 12.1" TFT 800x600 and it worked with 3.3.1, no special parameter, not even Chipset definition, just the following modeline: ModeLine "800x600" 28.32 800 808 1024 1040 600 600 626 640 +hsync +vsync And an optimistic choice of: HorizSync 25-79 VertRefresh 20-76 When I switched to 3.3.2, it stopped working, the only ways to make it do somthing sensible were with Option "no_program_clocks" But this way it stopped working with 16bpp, as it only detected: (--) SVGA: clocks: 28.32 28.32 28.32 28.32 (--) SVGA: Effective pixel clocks available: (--) SVGA: pixel clocks: 14.16 14.16 14.16 14.16 Using a manual `Clocks' definition did not work either, as X refused to accept it. The other way was without `Option "no_program_clocks"', but the display/card entered in a not well configured state, so I just went in standby state, then back to normal, and X worked. Not very convenient procedure... b.t.w. it's a Thinkpad 560, old chipset. I eventually decided to use XF86_SVGA from the 3.3.1, wich seems to work fine with the rest of 3.3.2 stuff. cheers, Lorenzo Vicisano. P.S. any suggestion on how dealing with 3.3.2 is very welcome. *--------------------*----------------------------------------------* / Lorenzo Vicisano \ http://www.cs.ucl.ac.uk/staff/L.Vicisano / / Dept. of Computer Science \ E-mail L.Vicisano@cs.ucl.ac.uk / / University College London \ Tel +44 171 419 3670 / / Gower Street, London, WC1E 6BT, UK \ Fax +44 171 387 1397 / *----------------------------------------*--------------------------* To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
