Hi,
I'm trying to run dual PCIE cards framebuffered. The aim of is to get 1 VGA
display for console and a 2nd one for the VGA/LCD of my HTPC case.
/dev/fb0 exists, but what about /dev/fb1 ? I look for docs nearly everywhere
but could no get infos on it.
Here what dmesg gives :
nvidiafb_probe START
nvidiafb: Device ID: 10de01df
nvidia #0: Test OK
nvidia #1: Test OK
nvidia #2: bus seems to be busy
nvidiafb 0000:03:00.0: Failed to register I2C bus nvidia #2.
nvidiafb: CRTC0 analog found
nvidiafb: CRTC1 analog not found
nvidiafb: EDID found from BUS1
nvidiafb: CRTC 0 appears to have a CRT attached
nvidiafb: Using CRT on CRTC 0
nvidiafb: MTRR set to ON
nvidia_set_fbinfo START
nvidia_set_fbinfo END
nvidiafb_check_var START
nvidiafb_check_var END
nvidia_save_vga START
nvidia_save_vga END
nvidiafb: PCI nVidia NV1d framebuffer (64MB @ 0xB0000000)
nvidiafb_probe END
nvidiafb_probe START
nvidiafb: Device ID: 10de016a
nvidia #0: Test OK
nvidia #1: Test OK
nvidia #2: SDA stuck low!
nvidiafb 0000:06:00.0: Failed to register I2C bus nvidia #2.
nvidiafb: CRTC0 analog found
nvidiafb: CRTC1 analog found
nvidiafb: EDID found from BUS1
nvidiafb: CRTC 0 appears to have a CRT attached
nvidiafb: Using CRT on CRTC 0
nvidiafb: cannot ioremap FB base
Any help will be really appreciated. I'm loosing my hair .
Regards
Pierre
