OK, the way to look at this is to scan the log file for the resolution: $ grep 1280x1024 Xorg.0.log (II) TDFX(0): Not using default mode "1280x1024" (hsync out of range) (II) TDFX(0): Not using default mode "1280x1024" (hsync out of range) (II) TDFX(0): Not using default mode "1280x1024" (hsync out of range) (II) TDFX(0): Not using mode "1280x1024" (no mode of this name) (II) TDFX(0): 1280x1024@75Hz Those first three lines are pretty clear. But why? $ grep sync Xorg.0.log (II) TDFX(0): Monitor0: Using default hsync range of 28.00-33.00 kHz (II) TDFX(0): Not using default mode "640x350" (hsync out of range) (II) TDFX(0): Not using default mode "320x175" (hsync out of range) (many more) OK, a horizontal sync of 33 kHz is definitely far too low for that kind of resolution. Looking at the X config file, you have: > Section "Monitor" > #DisplaySize 370 300 # mm > Identifier "Monitor0" > VendorName "HIQ" > ModelName "L90D+ D-SUB" > ### Uncomment if you don't want to default to DDC: > # HorizSync 31.0 - 83.0 > # VertRefresh 56.0 - 0.0 > Option "DPMS" > EndSection That's funny, because X should recognize the commented-out values, but it looks as if it can't find any information about the monitor by itself. Try uncommenting the two lines. Greg -- When replying to this message, please copy the original recipients. If you don't, I may ignore the reply or reply to the original recipients.
