Re: Blank virtual terminals
I have exactly the same problem with DVI only - VGA works fine even with vesafb. When switching to virtual terminal, monitor just displays out of sync message with values 86.7 kHz / 81 Hz, which seems to be same as the upper limit in monitor specs.
Both DVI and VGA work correctly with open source nv-driver, so it must be a bug in Nvidia's driver.
Linux Kernel 2.6.23
Nvidia driver x86-100.14.19
Monitor is LG L204WT and connected to DVI port of XFX FX5200 128 MB.
Nvidia's driver uses native resolution 1680x1050 @ 60 Hz with VGA without touching any config files. But when using DVI, I must explicitly enable correct modelines and
Option "ModeValidation" "DFP-0: NoMaxPClkCheck".
Without the option above Nvidia's driver cannot make native resolution work on my GPU/DFP combination. But virtual terminals work as they should...
I found couple interesting lines doing startx -- -logverbose 5, which are
(--) NVIDIA(0): Connected display device(s) on GeForce FX 5200 at PCI:1:0:0:
(--) NVIDIA(0): LG L204WT (DFP-0)
(--) NVIDIA(0): LG L204WT (DFP-0): 135.0 MHz maximum pixel clock
(--) NVIDIA(0): --- EDID for LG L204WT (DFP-0) ---
(--) NVIDIA(0): EDID maximum pixel clock : 150.0 MHz
Could someone from Nvidia say why this driver doesn't use the same maximum pixel clock that EDID tells?
