[Intel-gfx] Intel 82Q35 problem

[Jos Vos]

Hi,

Via a Fedora mailing list I was redirected to this list to post my
problem.

I have a problem with an IBM point-of-sale system with an Intel 82Q35
graphics chipset that does not work in RHEL6/F13, but that does work
fine on SLED 11 (older software).  OpenSUSE 11.3 seems to face the
same problem.  My system has a 15" display attached and also a VGA
port for a second display (to which I have connected a monitor now,
to see what happens).

This is the dmesg output on F13 with my comment inserted:

[...]
usb 1-5.2: new full speed USB device using ehci_hcd and address 3
usb 1-5.2: New USB device found, idVendor=05ba, idProduct=000a
usb 1-5.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 1-5.2: Product: U.are.U® 4500 Fingerprint Reader
usb 1-5.2: Manufacturer: DigitalPersona, Inc.
usb 1-5.2: SerialNumber: {3740B292-0CE7-0C45-BFC2-5053D2C76391}
fbcon: inteldrmfb (fb0) is primary device
###### HERE THE CONSOLE SWITCHES FROM PRIMARY TO SECONDARY DISPLAY !!! ######

registered panic notifier
No ACPI video bus found
[drm] Initialized i915 1.6.0 20080730 for 0000:00:02.0 on minor 0
[...]

So, at the point of the comment, the primary display becomes black
and from then on all output is redirected to the secondary display,
including subsequent X sessions.

In the dmesg output I also see:

[drm] set up 7M of stolen space
[drm:intel_init_bios] *ERROR* VBT signature missing
[drm] failed to find VBIOS tables

I can avoid the video switcthing with the "nomodeset" kernel
parameter, but after that X can not be started at all.

Any help is appreciated.
