Your log shows the following: (II) ATI: Shared PCI Mach64 in slot 0:20:0 with sparse PIO base 0x02EC etected. (II) ATI: VGA Wonder at I/O port 0x01CE detected. (II) ATI: Shared PCI Mach64 in slot 0:20:0 assigned to active "Device" section "ATI Mach64". [snip] (WW) Registering the following despite conflicts with estimated resources: [0] 0 0x000001ce - 0x0000f3fe IS[S] It appears you have multiple video adaptors in your system, possibly conflicting. Do you have a PCI card, and also an ISA or onboard video? or even a VLB card? Also, how much RAM is on the card? Interesting. The motherboard is a SuperMicro SBA370, with no on-board video. It has an AGP slot, but it's unused. I have a WinTV card in the system, but it's an input-only device. No Vesa-Local bus on the motherboard. No ISA video. There is only the single VGA connector coming out of my ATI Card. For the record it's a "Graphics Pro Turbo" card. I see in the manual that it has two video port addressing modes: Fixed I/O and relocatable I/O. I believe the card offered a maximum of 4 Mb of VRAM, and that's how much I have. Resolution I've gotten from this card in the past is consistent with having 4 Mb: 1280x1024x16, and under Windos 1280x1024x24. (The XFree86 version 3 Mach64 did not support packed byte mode so it couldn't do 1280x1024x24. I dimly remember experimenting with 1024x768x32 and deciding to configure consistently on both the win95 boot and the Linux boot at 1280x1024. 16bpp under Linux and 24bpp under windows. If I were to guess, I'd say the X Server is either double detecting the card because of some inadvertent fall-through in the code, or that the Fixed and Relocatable I/O is screwing us up. If it is the latter, then I suggest the driver be changed to use Relocatable I/O and to not try and find the fixed locations after that. According to the manual, the Fixed I/O video ports include 0x2e8-0x2ef which are normally used by COM4. The Relocatable I/O eliminates conflicts with COM4. Is there more I can do to help move this bug to resolution? Is trying 4.1.0 recommended? I can't reproduce this problem on any of 4 Mach64 cards I have tried, so it almost certainly is specific to your exact hardware combination. If you havent already, I recommend upgrading to 4.1.0-15 that we have released as erratum. All my Mach64 hardware works fine in current rawhide. I've tested it with a variety of resolutions. There are also new Mach64 bugfix patches present in rawhide. |
