I've just upgraded from potato to woody, including X from 3.3 to 4.1. As a result, I've lost the 1280x1024 mode that I've been using for years.
I have an ATI Graphics Pro Turbo card (Mach64 chip). In its printed manual, a 1280x1024 mode is documented with a refresh rate of 60Hz, a horizontal frequency of 63.9kHz and a pixel clock of 110MHz. In X 3.3, the output of startx would say (--) Mach64: PCI: Mach64 GX rev 1, Aperture @ 0xf0000000, Sparse I/O @ 0x02ec (--) Mach64: Card type: PCI (--) Mach64: Memory type: 6 (--) Mach64: Clock type: ATI18818-1/ICS2595 (--) Mach64: Maximum allowed dot-clock: 135.000 MHz (**) Mach64: Mode "1280x1024": mode clock = 110.000 In X 4.1, it says (II) ATI(0): Clock range: 9.00 to 80.00 MHz (II) ATI(0): Not using mode "1280x1024" (bad mode clock/interlace/doublescan) Does anybody know how can I convince X to use the mode I've been using for a long time?
