[Bug 773437] Re: Scaling display goes bright/white

 

I have just re-installed using ATI Proprietary driver and it actually
seems to be working now. Perhaps it was an issue with AMD's driver.

I am now using:

Catalyst: 11.9
Driver packaging version: 8.892-110914m-125703C-ATI
2D Driver version: 8.89.4
Catalyst Control Center Version: 2.13
RandR version: 1.3

I will confirm tomorrow with the same test I did initially so I can
check the same setup but with updated drivers.

Title:
  Scaling display goes bright/white

Status in “vinagre” package in Ubuntu:
  Incomplete

Bug description:
  I have a Sony VGN-FW31J laptop. Has ATI Radeon Mobility HD 3400 graphics card and I am using proprietary drivers:
  Catalyst: 11.3
  Driver packaging version: 8.723.1-100408a-098580C-ATI
  2D Driver version: 8.83.6
  Catalyst Control Center Version: 2.13
  RandR version: 1.3

  I am on Ubuntu 10.04.2 LTS and have Compiz enabled. I am using Remote
  Desktop Viewer 2.30.2 and I am using GNOME.

  The issue is that I can connect, view, and control a remote computer
  without any problem. However I am trying to connect to a computer with
  a larger resolution than my screen. I used to have the default
  proprietary ATI drivers (that came bundled with Ubuntu, sorry but I
  don't know versions etc.) and it worked fine. Since I updated to the
  above versions, when I switch on "Scaling" it displays odd. Most of
  the display is white and much of the colour is very brightened and
  looks like it is very distorted - I can't make out the actual image at
  all.

  I have tried turning off Compiz, and changing a few settings that I
  don't know what are for (like Vertical Sync) in the ATI CCC, but
  nothing seems to fix it.

  The only thing that works is if I do "vinagre reset" in a command line
  window, but as soon as the screen changes (e.g. I move my mouse
  around) the screen gets lighter and lighter again until it is white,
  and that also displays an error message saying: "Connection to host
  /reset/ was closed".

  Hope someone can help and find a more permanent solution! Thanks. Let
  me know if you need any more detail.
