Update, with additional info: Summary: SaX2 detects the correct hardware, but won't give me more than 1024x768 at a punishing 60Hz refresh rate. Windows on the same machine does far, far better, so I know it's not hardware limitations. In my /etc/X11/XF86Config file, I have many Modelines for 1152x864. In the "Section 'Monitor'", I have: (among other things) HorizSync 15-121 VertRefresh 30-160 In the "Section 'Screen'", I have: DefaultDepth 16 Subsection "Display" Depth 15 Modes "1152x864" "1024x768" "800x600" etc. EndSubSection Subsection "Display" Depth 16 Modes "1152x864" "1024x768" "800x600" etc. EndSubSection Subsection "Display" Depth 24 Modes "1152x864" "1024x768" "800x600" etc. EndSubSection In the "Section 'DRI'", I have: Group "video" Mode 0660 EndSection Of course, there are many more subsections, with variations for the other resolutions. And, of course, none of them say "etc.", I just truncated for readability. Does anybody have any suggestions as to what I can (or should) do to: a) get higher resolution (on the same laptop, connected to the same monitors, Windows has gone as high as 1600x1200, and there was no smoke or funny noise, but I prefer 1280x1024 at a higher refresh rate); b) get a refresh rate of at least 75Hz to nullify the flicker from the overhead fluorescents; c) or both... since bloody Windows from 1996 can do it without breaking a sweat. I haven't seen where SaX2 would let me modify its own very conservative offerings, so I'm willing to edit files directly if somebody can suggest what needs editing. Point to a good faq for the those with limited experience... and a big headache from staring at a 60Hz screen all day? Thanks for your time. /kevin
