Bug ID: 98149
Summary: EDID doesn't detect resolution 1440x900 correctly NV34
FX5200Go
Product: xorg
Version: unspecified
Hardware: x86 (IA32)
OS: Linux (All)

Dmesg log
I have an older laptop Toshiba P25-S609 which has NV34 based graphics (NVIDIA
FX5200Go). With 4.2 kernel and lower (and possibly 4.3) native resolution
1440x900 is detected properly. With 4.4 kernel and newer (e.g. Xubuntu 16.04.1
and newer) image on screen is displayed really weird. It is split in 4 parts,
and then it is shown from right to left (inverted). With xrandr --newmode and
cvt 1440 900 I can set the resolution, but then tty is still messed up.
I have tried to get the bug with options drm.debug=0x1e nouveau.debug=debug,
and vbios.rom from /sys/kernel/debug/dri/0/ and it is here:
http://filebin.ca/2xexyy0VGT9L/vbios.rom
Here is the image of what it does look like:

Dmesg log is attached below.

Looks like the included EDID in the VBIOS is:
00000000 00 ff ff ff ff ff ff 00 2e 0d 00 00 00 00 00 00 |................|
00000010 04 09 01 02 80 00 00 00 e2 00 00 00 00 00 00 00 |................|

*
00000070 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ff |................|
Which decodes to
Checksum Correct
Section "Monitor"
Identifier ""
ModelName ""
VendorName "KPM"
# Monitor Manufactured week 4 of 1999
# EDID version 1.2
# Digital Display
# Display Physical Size not given. Normal for projectors.
Gamma 1.00
Option "DPMS" "true"
Modeline "Mode 0" -hsync -vsync
EndSection
Which is obviously crap - no modelines are given, that's why we pick the
default 1024x768 & co modelines. Investigating further about how this used to
work. (Also manufactured in early 1999 seems surprising given that this is a
probably 2004 or so laptop...) But the checksum checks out, so we happily use
it.
Would you be so kind as include a dmesg with drm.debug=0x1e nouveau.debug=debug
from a working kernel?

Thanks for your kind reply. Here is the dmesg log and vbios.rom from the
working kernel 4.2.8. I am aware of that this is an old laptop, I am just
curious to find out what is the cause of this bug.

Right, so as I expected, the working version has
[ 2.538445] nouveau [ DRM] BIOS FP mode: 1440x900 (96210kHz pixel
clock)
So we messed something up, since we no longer follow down that path in
nouveau_bios.c. Perhaps ->is_mobile is no longer getting set to true? Or some
other reason...
