HI
I'm with Benedict on this one. I have a Matrox G400 Dualhead, which always
makes X throw a wobbler ("no screens found") if I allow the Framebuffer
stuff during the xserver configuration during setup. I have found running
dpkg-reconfigure xserver-xfree86 after installation and responding no to
Frambuffering has given me back my screens (Im using 2.4.18-bf2.4 and
running unstable and kde3.2).
The only other times it has happened has when there has literally been no
screens ie: none usable, although that was on a laptop so defualt colour
depth, screen size etc are a lot more important.
Also, not sure if you've already spotted/tried this but it does mention
about older kernels needing to be set to Vesa rather than i810
http://support.intel.com/support/graphics/linux/graphics.htm#5 eg:
++++++++++++++++++++++
Section "Device"
#no known options
Identifier "Intel 810"
Driver "vesa"
VendorName "Intel 810"
BoardName "Intel 810"
VideoRam 16384
#BusID
EndSection

Yep, all xfree86 related packages are installed.

Ok ... I've gone through my config this way, looking for any obvious
badnesses ... I'm using the i810 driver as per the instructions on Intel's
site for the 845GE graphics chip ... so i810 looks like what I should be
using.

The only (EE) message happens at the very end (full output attached if it's
possibly more revealing):
(II) I810: Driver for Intel i810 chipset: i810, i810-dc100, i810e, i815
(II) Primary Device is: PCI 00:02:0
(--) Assigning device section with no busID to primary device
(EE) No devices detected.
Fatal server error:
no screens found
When reporting a problem related to a server crash, please send the full
server output, not just the last messages. This can be found in the log file
"/var/log/XFree86.0.log". Please report problems to [EMAIL PROTECTED]

Here's the Device section:
Section "Device"
Identifier "Intel Extreme Graphics"
Driver "i810"
VideoRam 16384
EndSection
And the Screen section:
Section "Screen"
Identifier "Default Screen"
Device "Intel Extreme Graphics"
Monitor "View Sonic VA520"
DefaultDepth 24
SubSection "Display"
Depth 1
Modes "1024x768" "800x600" "640x480"
EndSubSection
[ .. snipped 1-16 .. ]
SubSection "Display"
Depth 24
Modes "1024x768" "800x600" "640x480"
EndSubSection
EndSection
... also I tried upgrading the kernel to 2.4.24, as the Intel docs implied
that the i810 driver required a kernel >= 2.4.11, but to no avail. The doc
is at http://support.intel.com/support/graphics/linux/graphics.htm
