SOLVED suddely black screen on 10.04 problem nvidia driver?

07-10-10
Solution till now?? !!

Followed the whole 'threat' /etc/X11/default-display-manager (in my case 'etc / sbin / gdm). Which stands for Gnome Display Manager gdm. That turned out to be 'disappeared'. Then booted into kernel (in my case 2.6.32.25) recovery mode. Then to root in terminal (last option in row). Xserver startup by entering 'startx', there are several ways possible. (read 'man-k xserver' and / or 'man xserver). I came into root in graphical interface. There I used "nvidia-settings" to change resolution etc., clicked
' apply ' and then 'save to X screen'. Obviously after looking whether the current version was available in the software. Used synaptic xserver to install 'gdm' again. Reboot and ........ since 6:30 this morning ........ I cannot complain Hope this is of some help to sombody.

06-10-10:
In the mean time I experienced, because I set the resolution through "save to xconfig file" instead of just using "apply" this xorg.conf:

Working on 1280 x 720 H 45Khz V: 60 Hz.

The machine stayed active for a few days, hibernated correctly, all fine. Then after a normal shut-down, no problems mentioned, monday morning: nothing at all not even through USB! All black. I remembered having an external HDD with an iso on it, I used that through USB; the system started as if it were on the HDD!! Nvidia intact, just wrong resolution. So restored old xorg.conf manually, lost "new beautiful" xorg.conf

Section "Module"
   Load "glx"
EndSection

Section "Device"
   Identifier "Default Device"
   Driver "nvidia"

EndSection

Changed to 1280 x 720 auto Hz and till now it works again. BUT before I have had occasions that only wanting to change users it all just falls back to 1280 x 1040 more then 60 Hz.

Maybe this is of some help.

Now: september 30, 2010

Update.
Xorg.conf now:
Section "Screen"
 Identifier "Default Screen"
 DefaultDepth 24
EndSection

Section "Module"
 Load "glx"
EndSection

Section "Device"
 Identifier "Default Device"
 Driver "nvidia"
 Option "NoLogo" "True"
EndSection

Nvidia Driver "current" is installed and working on latest updates of kernel and on Grub-pc 1.98-1Ubuntu7 Nvidia Common is installed as well.

X.Org X server -- evdev input driver 1:2.3.2-5ubuntu1
Screen now 1280x720 auto HZ

Still screen changes for no reason I can see to 1280 x1040.
In "Nvidia X server settings", I can't work with "save to X server conf file", because with start up I'll get a black screen again and can start all over again. So I only use "Apply".

See further info below

Hello:

So after a lot of problems upgrading to 10.04, eventually a clean install. First in 8.04, 9.10 and now as said in 10.04 for the second time, problems with the screen. It starts, gets a bit grey, then I see the GNU without touching keys, I choose the one at the top, Get's black again, Then some orange shows very short and I can log in, but not in any interface. Just as root in terminal. That's as far as I get.

The machine:
PC1(wired)10.04; ASRock N68; Dual AMD 64 Athlon(tm) II X2 240; RAM: 2048 DDR2; ATA Disk WD320Gb; Atheros AR5001X + W'less Sitecom 300N ; VGA compatible controller C61 [Nvidia GeForce 7025 / nForce 630a]; screen Acer 19'' V193HQ 1280x720 max.

Tried this:
https://help.ubuntu.com/community/BinaryDriverHowto/Nvidia

Installed this one
http://www.webupd8.org/2010/06/how-to-install-nvidia-25635-display.html
Worked great for 2 weeks and is now gone with the wind. Nowhere to find. Strange.....

This hereunder is what's on it, I can imagine it will conflict, but what can I get rid of and what not. And how, I can only work from USB-Stick.

This is the Xorg.conf on the moment:
Xorg.conf:
Section "Screen"
   Identifier "Acer HQ19"
   DefaultDepth 24
EndSection

Section "Module"
   Load "glx"
EndSection

Section "Device"
   Identifier "Default Device"
   Driver "nvidia"
   Option "NoLogo" "True"
EndSection

#default screen I removed and put in the screen name , but doesn' t work.

___________________________________________________________

Till a few days ago I worked with this xorg.conf:

Section "Screen"
   Identifier "Default Screen"
   DefaultDepth 24
EndSection

Section "Module"
   Load "glx"
EndSection

Section "Device"
   Identifier "Default Device"
   Driver "nvidia"
   Option "NoLogo" "True"
EndSection

Last time I changed the xorg.conf with the failsafe file and it worked again, now it does not.

I now also edited the kernel, removing quite splash with " nomodeset" . Nothing!
Kernel is the newest as well, ends at .24

The story:
Two days ago, in the evening just a normal shut down. In the morning the machine didn't start; black screen. The recovery mode even does not work. Everything I tried last times, I did it all again and more, nothing works, The grub is the newest, 1.98 1Ubuntu7

There are a few weird things I think:

    * The Nvidia seems to been gone. only the common-directory is left.
    * The nvidia is gone but Nouveau is back! I did not and do not understand .....

Now using a Live USB, I am able to enter, and changed the following:

    * I have removed video Nouveau
    * The Veza is off
    * Current Nvidia installled
    *But once I reboot everything is as it was earlier on. All changes DISAPPEAR again.

Then I looked at the grub, which looks ok to me. I have the 1.98 1Ubuntu7

    * The terminal now does NOT operate from the USB stick, the command: mount/dev/sda1/mnt sudo "does not exist"
    * Similarly, sudo grub-install / dev / sda - root-directory = / mnt "says" unknown command "

What happens durign START-UP: : start, pause, image fade equally, without keys, I then see Grub here and am able to choose a kernel mode (the latest), and sometimes even heavy the Ununtu logo, then flash comes by with an orange ubuntu color and then everything stops, flashing in root (in black, BUT so I can login. Not in a nice interface though. Any way. Ladies and gentlemen, thank you for the help to come.
Another important issue might be; someone earlier suggested doing an update, to remove 2.6.32.21 kernel, so that's not on the system no more. Can that be the problem? To be sure, the usb stick is made on Sept. 14.

Hans

Sept 15: 17:35 hours approximately
An "update": when I boot from the USB stick the firtst time, then everything runs as desired that way. When I don' t remove the USB portable memory, and reboot the PC through the stick! then the second time that even does not function. It acts the same as if it tried to boot from the hdd (Bios changed!). Very strange.

Right now I experience that I can't use the Icons nor on the panels as on the screen, when I remove the stick while working. Directories in Nautilus there the icons appear empty, no link behind it. That's probably because I've installed Nvidia current and uninstalled Vesa and Nouveau? After rebooting again; Current is gone and the other 2 are back. Like ghosts.

I just installed current again, is says it' s in action but after rebooting you have to start all over again.

Hope you can help me.

I answer more questions gladly.
