Graphics fail in fresh install (Compaq EVO N150)

[Duncan Lithgow]

Binary package hint: xorg

Ubuntu 8.10 alpha 3

Installation runs without any reported issues, but the screen is dead (no indication of power) after the startup progress bar, graphical login and everything from there fails to display. If I assume it's working and log in as if it is then there is some hard drive activity suggesting that the installation is working, but the display system is dead.

I have tried to drop to a terminal with CTRL+ALT+F1 and F4, but that doesn't work either.

I can log in to a root terminal if I select the rescue option in GRUB.

Please let me know what information I can provide to progress on this bug. My laptop is also listed here: https://wiki.ubuntu.com/LaptopTestingTeam/CompaqEvoN150

I have not yet gone through the whole of https://help.ubuntu.com/community/DebuggingXAutoconfiguration I will do this as I get time.

It's been a month already.. how about attaching /var/log/Xorg.0.log for starters?

This might be a bit late, however I guess my problem is similar to the one above:

When Ubuntu boots after the startup progress bar, the screen goes black and nothing happens. Even Ctrl+Alt+Fn and Ctrl+Alt+Back doesn't work.

I observed that behavior __ONLY__ when the NVidia Driver is installed and activated (at the time its newest version is 177 and I haven't tried with the older one). If without the NVidia Driver, everything works, however there is no 3D support...

I googled a bit and found that:

Perhaps the ABI has changed.

Enclosed to this post you will find my Xorg.20.log.

Same problem on the same laptop model : Compaq EVO N150.
Black screen after a fresh install ....

@Clement: are you able to provide some of the debugging information mentioned above? I don't have easy access to that laptop just now.

[Clement Quaquin (clement-quaquin)]

Ok, you can find it in attachment.

Workaround :

/etc/X11/xorg.conf.

# Add HorizSync and VertRefresh settings to the end of the "Monitor" section:

Section "Monitor"
   Identifier "Configured Monitor"
   HorizSync 31-60
   VertRefresh 50-75
EndSection

# And in the "screen" section :

Section "Screen"
  Identifier "Default Screen"
  Monitor "Configured Monitor"
  Device "Configured Video Driver"
  Subsection "Display"
     Modes "1024x768"
  EndSubsection
EndSection

Can you please let me know how this workaround can be implemented, as I have this exact issue using 8.10 general release?

[Clement Quaquin (clement-quaquin)]

@SK
Start ubuntu in recover mode, open a root session in command line mode, then edit the file /etc/X11/xorg.conf with vi editor and add the lines I wrote earlier.
Then restart your computer.

Tks Clement, I have a problem.

My Ubuntu VM that I created via the LiveCD has the X11 dir, however, I have just installed Ubuntu onto my N150 via a Netboot install, and it doesn't have the X11 dir after running ls within the /etc folder via root????
