Hi all
I have been googling over newsgroups and places trying to work out why I can't start X on an Alpha. I have little progress but have made some interesting observations.
Posts by people with the same problem as me were caused by them 1. using the wrong driver or 2. needing to specify the PCI:bus:slot:function. In my case I have the right driver and the right PCI slot (from lspci and /proc).
Now in XFree86.0.log file (--) stands for a probed value. Comparing an XFree86.0.log file from now PowerBook I have this....
log$ grep '(--)' XFree86.0.log Markers: (--) probed, (**) from config file, (==) default setting, (--) using VT number 7 (--) PCI:*(0:16:0) ATI Technologies Inc Radeon Mobility M7 LW [Radeon Mobility 7500] (--) Assigning device section with no busID to primary device (--) Chipset ATI Radeon Mobility M7 LW (AGP) found (**) RADEON(0): Depth 24, (--) framebuffer bpp 32 (--) RADEON(0): Chipset: "ATI Radeon Mobility M7 LW (AGP)" (ChipID = 0x4c57) (--) RADEON(0): Linear framebuffer at 0xb8000000 (--) RADEON(0): BIOS at 0xb0020000 (--) RADEON(0): VideoRAM: 32768 kByte (128 bit DDR SDRAM) (--) RADEON(0): Virtual size is 1280x854 (pitch 1280) (--) Depth 24 pixmap format is 32 bpp ...... snipped (II) Primary Device is: PCI 00:10:0
Now looking at the XFree86.0.log file fom the Alpha there is NO probing of the PCI bus. I addition there is the line: (II) Primary device is: ISA
To me this seems strange. Why isnt X probing? Why is the primary device ISA when the video card is in a PCI slot?

Last week I was asking if anyone had a graphics card I could use as mine failed. After a reboot I kept getting a "(EE) No devices detected." when starting X..... snipped...
Information:
XFree86.0.log says ...... (II) MGA: driver for Matrox chipsets: mga2064w, mga1064sg, mga2164w, mga2164w AGP, mgag100, mgag100 PCI, mgag200, mgag200 PCI, mgag400, mgag550 (II) Primary Device is: ISA (EE) No devices detected.
Fatal server error: no screens found
I have configured XF86Config-4 using dpkg-reconfigure.
lspci says 0000:00:05.0 VGA compatible controller: Matrox Graphics, Inc. MGA 2064W [Millennium] (rev 01)
/proc/pci says
PCI devices found:
Bus 0, device 5, function 0:
VGA compatible controller: Matrox Millennium (rev 1).
Medium devsel. Fast back-to-back capable. IRQ 18. Non-prefetchable 32 bit memory at 0x9000000 [0x9000000].
Non-prefetchable 32 bit memory at 0x9800000 [0x9800000].
So according to the above I have a video device detected at boot time.
The XF86Config-4 file has:
Section "Device" Identifier "Matrox Millenium" Driver "mga" BusID "PCI:0:5:0" EndSection
