[GeForce 9500 GT] X has black screen

[Sebastian Bengtsson]

Video Card: nVidia Corporation NV15DDR [GeForce2 Ti] [10de:0151]

Binary package hint: upstart

(Don't know whether to file this against upstart, linux, xsplash or xorg.)

Summary:
Live cd boot never gets to X, only blank screen. TTY screens also blank. System still responds.

ISO-image: ubuntu-9.10-beta-desktop-i386.iso

What I did:
Booting Karmic Beta desktop live cd.
Boot menu: Language=English, Keymap=Swedish. Boot to live cd environment.

Results:
Message flicker by with something like
"[ kerneltime] pci 0000:00:00.0 ...BAR ... Adress space collision"
(grey circle of friends/Ubuntu logo)
"Starting early crypto disks"
"Starting init crypto disks"
"Starting remaining crypto disks"
(blank screen)
Sound: drum intro (with some disjointed-wave-popping / clipping)
(still blank screen)
(cd drive spindown)

This leaves me with a blank screen.
Trying to switch to TTY with Ctrl-Alt-F2, still blank screen.
Hitting NumLock lights numlock led on keyboard.
Hitting Ctrl-Alt-F3 switches numlock led off.
Hitting Ctrl-Alt-F2 switches numlock led on again.

Hitting Ctrl-Alt-Delete brings up Ubuntu logo and ejects cd tray with "remove cd" message.

I repeated the process with "failsafe graphics" in the boot menu. This time an ncurses message flashed by (no time to see what it says) before screen blanks again, followed by the drum sound. This time the numlock/tty trick does not work, but Ctrl-Alt-Delete initiates the shutdown process.

"Check CD for defects" says cd is fine.

Caught the BAR-message on camera, it says:

[Sebastian Bengtsson (5ebastian)]

More readable lspci info.
Generated under Hardy. However, plain old lspci had no diff between my hardy-install and when I ran lspci under ash on the ubuntu-9.10-beta-server-i386.iso, so hope there is no diff for the verbose version either.

Reassigning to cryptsetup based on the last reported messages on screen

[Brian Murray (brian-murray)]

Thanks for taking the time to report this bug and helping to make Ubuntu better. I'm under the impression that the server iso boots fine is that correct? If it is then this is likely an xorg bug. Thanks in advance!

[Sebastian Bengtsson (5ebastian)]

Yes the server iso boots fine. I went through the first steps ofdebian-installer and bailed when I got to the partitioner. I would say it is likely an xorg problem, but it is an xorg problem that blocks any usage of the live cd or graphical installer. Thus it is a bug for the entire live-cd.
(If it booted and threw me into a dark and friendly tty where I could fix my xorg problems, then it would be a classical "xorg bug". )
Are there any other logs or data on my machine that is need to make the bug report more complete?

[Giuseppe Pennisi (giupenni78)]

I have the similar problem with Kubuntu Karmic Beta (downloaded 10 oct. 2009).
The LiveCD boot is very slow with a black screen, but when show the login the mouse and keyboard not works.

[Brian Murray (brian-murray)]

@giuseppe - while your problem may sound similar it is entirely different as the original reporter does not see the login screen at all.

[Kálmán, Ferenc (fkalman)]

I have the same problem. The LiveCD boots with a blank screen.
I upgraded my cloned Jaunty distribution with Karmic, and the booting is the same (only blank screen)
I have yet another error message:
ACPI: I/O resource piix4_smbus [0xb00-0xb07] conflicts with ACPI region SOR1 [0xb00-0xb0f]
I tried booting with acpi=off, but the same effect.

Have done some more testing and concluded that it actually boots all the way to the desktop.

After boot is finished and the cd spinns down I can hit Alt-F2, type sudo reboot, and the reboot is initated.
Tried with another monitor (TFT, previously only tried with CRT). Same results.
The TFT monitor complains about "scanning out of range" when I push it's auto-adjust button. The CRT did not say that (although it has the ability to do so).

[Kálmán, Ferenc (fkalman)]

I have donloaded the latest RC version, but this version also not boots. The boot process hangs with empty screen, and not responds to any key.
"We consider this release candidate to be complete, stable, and suitable for testing by any user."
:-) It is stable, but not working at all!

Hi I am affected from the same bug. Tested with an earlier alpha version and the current karmic RC with 32bit and 64bit. After the boot menu , the ubuntu logo flashes and it disappears showing a cursor blinking, no feedback no nothing. In jaunty it works perfectly.

CPU: Phenom II x3 720be
M/B: M4A79 deluxe
GPU: ATI 3850 512MB

The only similarity that I can find is the AMD platform.

[Pere Toran (petovi)]

I am affected too. What I did is install ubuntu from the alternate cd and then I started ubuntu from recovery mode. A prompt appeared asking for the user/pass and, after installing the nvidia drivers, I typed "sudo nvidia-xconfig" (which writes a valid xorg.conf under /etc/X11/ path). Restarted the PC and all loaded fine.

I know it doesn't solve this bug but its a workaround...

[Thomas Schöpfer (t-schoepfer)]

Hi I have a similar problem. I used current Kubuntu beta live CD (64bit).
It boots to a black screen with just a cursor visible.
On console 2 it stays at "cryptsetup".

Can you please try to get an X.org log from this box? It seems that the X.org driver (nv on the live system) used on this system does not work.

For this, you need a second computer, both of which are on a common network. The one which fails needs ethernet connection since you won't have a chance to enter wifi passphrases.

Please do the following:

 - Boot the live CD
 - select the language in the boot menu
 - press F6, Esc, then enter "text", then press Enter. This will boot the live system without starting X.org. Wait until the bouncing ubuntu logo goes away and you get into a text console.
 - sudo apt-get install openssh-server
 - "passwd" and enter a real password for the ubuntu user.
 - "ifconfig eth0" and note the IP address ("inet addr: xxx.xxx.xxx.xxx").
 - From the second computer, log into the live system with "ssh <email address hidden>", using the IP address from above, and the password you just set when it asks you.
 - On the live system, now do "sudo gdm-binary". This will start X and presumably cause a black screen. (If not, reproduction failed..)
 - From the second computer, fetch the logs:

    scp <email address hidden>:/var/log/kern.log /tmp/
    scp <email address hidden>:/var/log/Xorg.0.log /tmp/

Attach /tmp/kern.log and /tmp/Xorg.0.log here. Thanks!

(II) NV(0): Output DVI0 using initial mode 1680x1050
(II) NV(0): Output DVI1 using initial mode 1680x1050
(--) NV(0): Virtual size is 1680x1680 (pitch 1792)

Do you actually have two DVI monitors attached? Does this resolution look alright to you?

Nothing DRMish in kern.log (not surprisingly, since this is the nv driver), and X log looks normal. Bryce, any idea what to further check here?

[Kálmán, Ferenc (fkalman)]

Yes, I have two DVI monitors (1680x1050 each).
If I disconnect one of them, then the boot process is correct (no black screen).

[Kálmán, Ferenc (fkalman)]

After upgrade to Karmic the system doesn't boot, too.
I attach my xorg.conf-s (before and after upgrading).
There is no relevant difference between them.

[Brian Murray (brian-murray)]

This might be a duplicate of bug 43710.

[Sebastian Bengtsson (5ebastian)]

This is not specific to GeForce 9500 GT. I have a much older GeForce2 on this machine. And that card definitely does not have a DVI-I output.

[Trevor Owen (t-owen)]

I have a similar problem with Karmic Kubuntu on a Dell Inspiron with an integrated Intel 82845G/GL video card. Boot is completely normal up to the point the splash screen that shows the icons for hardware, desktop, settings, network, and KDE appearing in succession (I may have the order wrong, but the process finished with the big KDE logo icon). The screen then goes blank, except for the mouse cursor. I can bring up the "Run" dialog box by Alt-F2, and using it have been able to bring up all of the programs I expected to be installed, except the program window appears in a very minimalized form in the upper left corner. By dragging a corner I can make the window a normal size. Programs work normally, but when I minimize the window they disappear. To shutdown I run Alt-F2 "Shutdown", and am able to log out. Ubuntu-desktop and Xbuntu-desktop have been installed and work normally.

[Jens Janssen (jayjay)]

I'm also affected using GeForce 9500GT (2x DVI) with 1680x1050 screens.

To start LiveCD I have to switch to 1280x1024 screen.

[Bryce Harrington (bryce)]

Thank you for reporting this issue about xserver-xorg-video-nv. Starting
with Lucid, Ubuntu is transitioning to using the -nouveau video driver
by default instead of -nv. The reason for this change is because
upstream development for the -nv driver has been quite slow. We are
quite pleased with the upstream development speed for -nouveau, and hope
this will translate into swifter bug fixes as well.

Because of this, I'm closing this bug report at this time. I'm marking
it wontfix because what you describe is probably a valid issue, but we
do not have further plans to work on it in Ubuntu. If you would still like
to see this issue investigated, I would encourage you to file it
upstream at http://bugs.freedesktop.org/.
