Nothing new. I've got this problem since 177.82.

Default Re: black screen when switching to a virtual terminal with nvidia 180.50 x86

So, any news about this issue?
Looks like is a distribution independent problem but it affects many acer models with a GeForce9600GT...
Do nv developers have any chance of getting their hands on one of these models (ie acer 5930) so they could see the problem by themselves?

This issue is difficult to report because there's nothing that "fails" or crashes... Switching from X to any VT leads to a black screen... But console really works, commands can be "blindly" typed, just there's no visual feedback. Even switching again from VT to X works.

Question Re: black screen when switching to a virtual terminal with nvidia 180.50 x86

this problem is not acer related. I have a clevo notebook with a 9600M GT GPU and I'm experiencing the same problems. maybe it's BIOS related. what interests me is if that the black screen problem also cames along with the powermizer problem not clocking the GPU up unter load making opengl games slow as hell and vdpau 1080p playback impossible.

any word from the NVIDIA guys if and when we can expect a bugfix release?

Oh, so it's not acer-related... It's good to hear that (sort of)...
I didn't know about ogl apps performance and powermizer.

Anyway, since nvidia-bug-report doesn't contain any warning or error, i tried doing these steps:
  1. start X with logverbose 6 option
  2. save nvidia-bug-report
  3. switch to vt
  4. switch again to X
  5. save another nvidia-bug-report
  6. diff the two logs

Ignoring obvious differences that's what appeared in Xorg.log after switching again from a black vt:

Code:
(II) Open ACPI successful (/var/run/acpid.socket)
(II) NVIDIA(0): Setting mode "1280x800"
(II) NVIDIA(0): ACPI: AC state file path: /sys/class/power_supply/ADP1/online
(II) NVIDIA(0): ACPI: the system is running on AC power
(WW) NVIDIA(0): ACPI: invalid device ID in the file
(WW) NVIDIA(0):     /proc/acpi/video/VGA/DVI/info
(WW) NVIDIA(0): ACPI: the driver will respond to display change hotkey
(WW) NVIDIA(0):     switches by inferring the new display device combination,
(WW) NVIDIA(0):     rather than getting the new display device combination
(WW) NVIDIA(0):     from the ACPI subsystem.
(II) NVIDIA(0): ACPI display change hotkey events enabled: the X server is new
(II) NVIDIA(0):     enough to receive ACPI display change hotkey events.
(WW) NVIDIA(0): ACPI: failed to determine the system's docking state: Unable
(WW) NVIDIA(0):     to find /sys/devices/platform/dock.*/docked file. Kernel
(WW) NVIDIA(0):     version may be less than 2.6.20 or dock.ko driver may not
(WW) NVIDIA(0):     be present
Maybe this gives some hint?

edit: disabled sync to vblank, tested glxgears and q3 demo... powermizer doesn't let the card go beyond perf level 1 out of 4 (clock:275 mem:300MHz instead of 500-800MHz)...

I have the same problem with 8600GT and with 9600GSO 384mb too. The same problem with the beta 185.19, and with 180.51. Problem was appear then I was change my old (it was die) 7300 to 8600GT near year before now.
Motherboard ABIT KN9SLI, two Video cards (8600GT in 8x PCIe and 9600GSO 384m in 16X PCIe), FEDORA 9 - x86_64, AMD X2 4000+ CPU. So problem is not only at notebooks, the problem is common for all who use 8XXX and 9XXX NVIDIA GPU. You can find many bug reports here about this problem. And many "solutions", which was help to some peoples, but not all. Any of such solutions was not help to me also.
PS Only one difference I found between 185.19 and 180.51 - then I was use 185.19, I was have blank black console with blinking cursor, and with 180.51 now, I have nice black console without any blinking cursor - full excellent black console.

I don't understand why is it so difficult to fix this bug, VTs work with the nv and nouveau drivers.

In another thread I cannot trace back anymore someone from nvidia said that the only way for them to fix it is to send them the affected computers... but what can they do with my notebook that I cannot do myself if they tell me?

Please nvidia tell us any debugging you may need and fix this nasty bug at last!

Do any of you with the black screen vt issue also experience the powermizer issue not throttling up the GPU to full speed under load?

uuh...that makes two users already. anyone else? I get the bad feeling that we gonna have to wait a looong time for a fix - if we ever see one from nvidia. good thing that I have a MXM slot in my notebook so I can replace my 9600M with a Radeon 4xxx series card as soon as the open source driver matures.
