Problem with recent 190.40 driver on Acer Aspire 5739G laptop.
The first problem was with invalid EDID response:
Code:
(--) Nov 10 17:37:02 NVIDIA(0): --- EDID for AUO (DFP-0) ---
snip
(--) Nov 10 17:37:02 NVIDIA(0): Detailed Timings:
(--) Nov 10 17:37:02 NVIDIA(0): 1366 x 768 @ 60 Hz
(--) Nov 10 17:37:02 NVIDIA(0): Pixel Clock : 69.50 MHz
(--) Nov 10 17:37:02 NVIDIA(0): HRes, HSyncStart : 1366, 1414
(--) Nov 10 17:37:02 NVIDIA(0): HSyncEnd, HTotal : 1446, 1437
(--) Nov 10 17:37:02 NVIDIA(0): VRes, VSyncStart : 768, 771
(--) Nov 10 17:37:02 NVIDIA(0): VSyncEnd, VTotal : 775, 806
(--) Nov 10 17:37:02 NVIDIA(0): H/V Polarity : -/-
For which the driver complains:
Code:
WW) Nov 10 17:37:02 NVIDIA(0): Mode is rejected: This mode's horizontal sync end (1446)
(WW) Nov 10 17:37:02 NVIDIA(0): exceeds the horizontal total size (1437).
After some googling I managed to force it works with following xorg config:
Code:
Section "Monitor"
Identifier "DFP-0"
VendorName "AUO"
ModelName "AUO"
DisplaySize 340 190
HorizSync 48.4 - 48.4
VertRefresh 60.0 - 60.0
Option "DPMS"
Modeline "1366x768_60.00" 69.5 1366 1414 1446 1447 768 771 775 806 -HSync +Vsync
EndSection
Section "Device"
Identifier "GT 240M"
VendorName "nvidia"
Driver "nvidia"
BusID "PCI:1:0:0"
Option "ModeValidation" "NoDFPNativeResolutionCheck"
Option "ExactModeTimingsDVI" "true"
EndSection
Section "Screen"
Identifier "Screen0"
Device "GT 240M"
Monitor "DFP-0"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1366x768_60"
EndSubSection
EndSection
The second problem is that after quitting xorg the black screen appears and whole system hangs. I don't know how to fix or debug it, maybe the driver bug?
nvidia-bug-report.log is attached.
