1280x720 refuses to work now
 
1 Attachment(s)
Ok, I'm baffled. I used to be able to use 1280x720 resolution, but I upgrade my Debian distro to the latest and now it refuses to use the 1280x720 resolution. Yet when I run startx -- -verbose 5 -logverbose 6 I see the following:

(II) NVIDIA(0): Validating Mode "1280x720":
(II) NVIDIA(0): 1280 x 720 @ 60 Hz
(II) NVIDIA(0): For use as DFP backend.
(II) NVIDIA(0): Mode Source: EDID
(II) NVIDIA(0): Pixel Clock : 74.25 MHz
(II) NVIDIA(0): HRes, HSyncStart : 1280, 1500
(II) NVIDIA(0): HSyncEnd, HTotal : 1540, 1650
(II) NVIDIA(0): VRes, VSyncStart : 720, 740
(II) NVIDIA(0): VSyncEnd, VTotal : 745, 750
(II) NVIDIA(0): H/V Polarity : +/+
(II) NVIDIA(0): Mode is valid.

but then later in the log i see:

(II) NVIDIA(0): --- Modes in ModePool for LG 37LC2D-UD (DFP-0) ---
(II) NVIDIA(0): "nvidia-auto-select" : 1024 x 768 @ 60.0 Hz (from: X Server, VESA, EDID)

(II) NVIDIA(0): "640x480_60" : 640 x 480 @ 60.0 Hz (from: VESA, EDID)
(II) NVIDIA(0): --- End of ModePool for LG 37LC2D-UD (DFP-0): ---


What happen to my 1280x720 mode???? Of course X11 won't start up in that mode now!:(

I tried using the older driver 8774 which I believe is the one that used to work, but now I get compile errors when I try to use it.

Attached is my complete xorg.log file.

Re: 1280x720 refuses to work now
 
In your log, I see:
(WW) NVIDIA(0): Mode is rejected: Mode (1280 x 720) is too large for DFP
(WW) NVIDIA(0): Native Resolution (Max: 1024 x 768).

You should try adding the ExactModeTimingsDVI driver option, and/or the ModeValidation option. See the driver README for more information. If you need further assistance, please generate and provide an nvidia-bug-report.log.

Thanks,
Lonni

Hey man,

Look further down inside the log:

Code:

(II) NVIDIA(0): Native backend timings for LG 37LC2D-UD (DFP-0):
 ...
 ... 
 ...
(II) NVIDIA(0):  Validating Mode "1280x720":
(II) NVIDIA(0):    1280 x 720 @ 60 Hz
(II) NVIDIA(0):    Mode Source: EDID
(II) NVIDIA(0):      Pixel Clock      : 74.25 MHz
(II) NVIDIA(0):      HRes, HSyncStart : 1280, 1500
(II) NVIDIA(0):      HSyncEnd, HTotal : 1540, 1650
(II) NVIDIA(0):      VRes, VSyncStart :  720,  740
(II) NVIDIA(0):      VSyncEnd, VTotal :  745,  750
(II) NVIDIA(0):      H/V Polarity    : +/+
(WW) NVIDIA(0):    Mode is rejected: Mode (1280 x 720) is too large for DFP
(WW) NVIDIA(0):    Native Resolution (Max: 1024 x 768).

Add these options to the DEVICE section in /etc/X11/xorg.conf

Code:

Option "ExactModeTimingsDVI" "true"
Option "ModeValidation" "NoDFPNativeResolutionCheck"

:D BINGO!!! That did it....many many many thanks. I'm usually pretty good about figuring this stuff out, but this one was throwing me for a loop since it worked with an older driver at one time.
