Graphics Resolution- Upgrade /Blank Screen after reboot

**bogan** · October 27th, 2011

Hi! MAFoElffen, Thanks!!
Short response:
!Eureka! It worked!! well 99% anyway!
Though the result, so far, does not seem to be much different from Linux 11.10 on 2.6.38-8, except that WiFi connects almost instantly.

Slightly longer response:
'sudo update' gives: update command not found: should it not be "sudo apt-get update"?.
Similarly, should " reconfigure light-dm" not be " reconfigure lightdm".?
I tried them both ways. The latter showed lightdm already selected as default.
The update gave a long list of errors and warnings about could not resolve http://Ftp.ticklers.org....ubuntu. Presumably, because WiFi was not connected.

Even longer report:
' sudo nVidia uninstall' gave:

Code:

"ERROR: File  '/usr/lib-xorg/modules/extensions/libglx.so' is not a symbolic link".  [OK].
  And: " unable to restore File 'usr/lib/mesa/libGL.so.1.2' ".  [OK].
 Then:  "uninstall 270.41.19 complete".

'Install nvidia-current' went OK.
' Sudo nvidia-config' gave four warnings about unable to find CorePointer and CoreKeyboard, and them not being specified.

I can now access gedit and the Xorg.x.log files.
The crucial bit of Xorg.5.log seems to be:

Code:

 (EE) Failed to  load module "nvidia" ( module-specific error, 0)
(EE) No drivers available.
fatal server error :
no screens found

If you want to see any more or other files please say.

Queries:
1. What is command to show nVidia driver version installed? Edit: Xorg.0.log shows: "NVIDIA dlloader X Driver 280.13". Is that Nvidia-current.??
2. Does 11.10 Unity no longer support Panels??
Clicking on Applications/Accessories/Panel gives a Launcher that pulses, but nothing changes, if I select it it goes away. ( sorry if that is off topic).

Chao! and thanks again miracle worker.
bogan.

Thanks, MAFoElffen.

On start up, if I allow normal (choose default kernel 3.0.0-12-generic with grub line set with "--verbose single") all boot messages are in 'white block' garbled unreadable fonts. Then a ssh access attempt complains

Code:

ssh: connect to host [local ip address] port 22: Connection refused

If I choose to boot the 3.0.0-12-generic (recovery mode), all boot messages are readable and I can ssh into machine. When asked, I choose to 'resume normal boot' and boot continues to present a command prompt displayed on my monitor. Now, I can get in machine via ssh through my desktop terminal, therefore I am not trying the suggestions on post 715.

Via ssh, I have updated and upgraded to most current packages as of this morning. (Updated xserver-common (2:1.10.4-1ubuntu4.2), xserver-xorg-core (2:1.10.4-1ubuntu4.2) and other stuff this morning.)

And finally, the Mythbuntu iso disk does the same style install as the alternate cd Ubuntu (Unity) desktop disk. And uhm, I don't think this install method really matters to what you are trying to help me with. I might be wrong, though.

Hi MaFoElffen

Sorry to see those error messages. I was helping someone with Kubuntu that was getting the same errors. He ended up having to reinstall to correct it. What we figured out, was that "something" either got corrupted or that files that were supposed to be removed left something orphaned...

For you- In 11.04, GDM was the Desktop Manager. For 11.10, GDM was replaced by lightdm. You shouldn't be having any meassages about GDM at all...

Try this from a command line:
Code:

sudo apt-get remove --purge gdm ligthdm
sudo apt-get install lightdm

Tell me how that goes...

I'm actually on 10.04 .... but I found instructions on installing lightdm on Lucid so will try that when I'm at home

Thank you
Paul

Code:

 sudo update
 sudo nvidia-installer --uninstall
 sudo apt-get remove nvidia-*
 sudo apt-get install nvidia-current  
 sudo nvidia-xconfig  
 sudo apt-get upgrade

That will install "your" drivers for your model NVidia card.

It should boot and be fine. Check this file- /etc/modprobe.d/blacklist.conf. Make sure it has these 2 lines in it:

Code:

blacklist nouveau 
blacklist lbm-nouveau

If not, add them.

Sidenote- I'm not recommending the newest nVidia binary (290.x). It doesn't work with unity. v285.05 works well though. If you want to use that instead... Its a bit more detailed and manual to install. I have a tutorial, if needed for that... (Post 280)

Please tell me how it goes.

Thanks so much for the reply!

Here's how it went:

Code:

sudo update

I got an error "command not found," so I ran:

Code:

sudo apt-get update

The command:

Code:

sudo nvidia-installer --uninstall

also gave me a "command not found."

Code:

sudo apt-get remove nvidia-*

removed two files, nvidia-common and nvidia-desktop. When I ran:

Code:

sudo apt-get install nvidia-current

it looked like it installed 280.13.

Code:

sudo nvidia-xconfig

gave me "Warning: unable to locate/open X configuration file. New X configuration file written to '/etc/X11/xorg.conf.'

Code:

sudo apt-get upgrade

updated a whole slew of files.

When I rebooted, I got through to the encryption password-entry page, which is very low-resolution--maybe 640 x 480?--just like it used to be in 11.04 with the proprietary nvidia drivers before I used this workaround.

Once I entered my encryption passphrase and got to the actual Ubuntu login screen, everything looked great, and I'm writing this reply from the problem machine.

I have added the two lines for blacklisting the nouveau driver, which were not in my /etc/modprobe.d/blacklist.conf file.

Thanks again for the help. I was really stuck.

I'm thinking of reinstalling with just home folder encryption instead of whole-disk encryption to get around the nasty graphics at the encryption screen, which has been an issue since 10.04. Just have to research how much loss in security that will entail.

Hi, Bobwdn, a suggestion from bogan:
You posted:

And finally, I cannot collect any info from /var/log/xorg.0.log as I am running in recovery mode. I think, if I remember correctly that x does not run in recovery mode. Code:
cat /var/log/xorg.0.log cat: /var/log/xorg.0.log: No such file or directory

I had similar difficulties with no such file as /var/log/xorg.0.log responses.
Try "Xorg.0.log". The 'X' has to be uppercase, and the 'O' is a nought!
I got caught by both.
Chao!

**TexasPedi** · October 27th, 2011

Tried it---then rebooted--the computer goes to Stopping System V runlevel compatibility withj [ok] on the the right corner.

**Tronnie Dobbs** · October 27th, 2011

Hey MAFoElffen,

I tried your suggestion and got the following results...

code

sudo update

came back with 'command not found'

code

sudo nvidia-installer --uninstall

also came back 'command not found'

code

sudo apt-get remove nvidia-*

gave me 'E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem'

Also, of the many choices of versions to attempt to edit from the GRUB menu, I assume that I'm looking for 2.XX.XX for the kernel, not the first listed 3.XX.XX? Is that correct? Since I just reinstalled 11.10 to run alongside the auto-updated 11.10, I assume that I'm looking for the slightly older one...

Any thoughts?

bogan.

yes- was my typo's... too many long hours with no sleep. (Dr's are checking into that.)

I beleive either 280.13 or 285.05 is nvidia current now. In xorg logs ) is current, 5 is 5 times past tense. If not 285 yet it will be soon. On the panel problem, if you keep with current, it will automatically update itself to whatever is current in the Ubuntu updates. (Unlike the binary that you have to tell it to update. When it gets to the 285, the panel problem should go away. 280 has some slight problems with unity, but only for some people with older hardware.

What your previous workaround's script did is in about midway in post 1...
- Open /etc/default/grub with preveleges...

Code:

gksudo gedit /etc/default/grub

Say you want the grub menu and all before the graphics boot to be 1025x798 24bit...You would look for the line that said

Code:

#GFXMODE=640x480

Uncommented it and change the resolution and depth (the depth is optional) to

Code:

GFXMODE=1024x768x24

The rest of that script installs and configures ubsafb (and x86d). It worked with 10.04 and 10.10 in replacement of the driver's framebuffer.... I believe when you are dealing with the newer Nvidia and ATI drivers, that has some holes in it.

ubsafb is an old and limited driver with limited support of reslotions and absolutely no acceleration at all.

Starting with 11.04, 11.10 and now 12.04 (I'm testing now)... Might as well say since GNU Grub 1.99~RC1 and newer- The graphics mode Grub passed via grub through kms seems to take care of take just fine without anything additional. ...At least in my tests.

Okay, so putting "=verbose single" there is going to make it permanent (until changed back) that it will boot to a TTY Text Console. Wasn't my instaruction to do that temporarily in Grub on-the-fly?

xorg.0.log should be Xorg.0.log with a capitol X...
From a tty text console it booted okay with no errors into a text console?
