If I boot he laptop with a CRT connected and run X windows everything works. The x windows log reports its using a refresh rate code of 12 Compile atyfb without generic LCD support. If I load atyfb the screen is almost there but lots of the text is messed up. Line spacing seems correct but the actual text is unreadable. Like a clock is off or something If I now load the X windows driver (Still using ATI driver and not FB) the same type issues apears on the graphics. It's almost there but some pixels appear to be mssing or in the wrong spot. The X log now is pretty much identical but says that its useing a refresh rate code of 7. XCLK and reference clocks are the same. If I boot under the LCD and run X I get refresh rate of 12 When I load atyfb the LCD blanks out. But if I "modprobe atyfb;startx" I get the same wiggy screen as under an CRT and again a refresh code of 7. If I enable the Generic LCD support and load atyfb the LCD now displays data but has the same problem as the CRT and againg a refresh rate code of 7 if I run X and similar issues as the CRT setup yet the wiggyness is different. Still mostly recognizeable though. Where does atyfb calculate what it need to to set the refresh rate code and any idea why it might be doing it incorrectly on this laptop? Its my understanding that the atyfb tree in 2.4 currently has the best M1 support and not 2.6.x. If not then can someone point me to where I can find the latest patch for 2.6 ------------------------------------------------------- This SF.Net email is sponsored by Sleepycat Software Learn developer strategies Cisco, Motorola, Ericsson & Lucent use to deliver higher performing products faster, at low TCO. http://www.sleepycat.com/telcomwpreg.php?From=osdnemail3
