[Bug 756818] Re: Unity Live session nvidia display unuseable

 

The Sansui monitor trial reminded me that there are other outcomes
beside the freezing and repeating pattern of dots.  This trial set
ALMOST worked from the trials of the LIVE disks of Unity, GNOME, KDE
Plasma, and Cinnamon desktops, but random patterns made the display
still unusable.  The graphics did not freeze, and the nVidia proprietary
driver may have worked, did not try in this set of trials.  The other
outcome which happened on Unity, GNOME/GNOME Classic and Cinnamon was to
have yellow and white on white background for the screen text and other
graphic elements, rendering most text onscreen unusable.  BTW, the
Sansui SLED2900I model was capable of 1280x1024.

I tried Ubuntu 14.04 for Unity.  Xubuntu 14.04 & 14.10 worked fine, as
is PCLinuxOS LXDE.

Next test would be to check using the nVidia proprietary driver and/or
installed system.

Bug description:
  E-Machines T5212 Intel Pentium D805 2G/nVidia GeForce 6200TX 256M PCI-e add-on display card/Etronix 1701B 17" 1280x1024 LCD display
  Natty beta download from 6 April 2011
  Presently operating on same boot CD after checked for errors in disk,  using the motherboard ATI Radeon Express 200 display driver.
  I have had problems in the past because the Etronix display card doesn't correctly report an EDID.

  When I tried to boot with my 'normal' nVidia display card in the
  system on the Natty beta CD burned from a download from Ubuntu.com,
  everything seemed to operate normally until I got to the desktop
  display.  I just used the defaults, did not try to download
  proprietary drivers, indeed didn't touch the keyboard after beginning
  the boot from the CD.

  At the desktop, the display would show for a second, then go black for
  a second, cycling endlessly.  The only variation was that the display
  when showing the background of the desktop would sometimes show the
  Unity menu, sometimes the top bar, sometimes just the background, in
  no sequence that I could determine, although I left it running for
  about 30 seconds to see if it would stabilize.  USB keyboard and mouse
  had no effect.  I got out by turning off the power.

  Any further information which I can supply?
