High CPU usage by Xorg process when scrolling in firefox or adobe reader or in any other application

[Ankit Bansal]

Binary package hint: xorg

When i start firefox or adobe reader to read some file or URL, the Xorg process usage goes as high as 100 % and the scrolling makes the screen to flicker. The /var/log/Xorg.0.log.old shows the stack trace. glxinfo command also does not work.

output of glxinfo from command line is as follows:
ankit@ankit-laptop:~$ glxinfo
name of display: :0.0
X Error of failed request: BadRequest (invalid request code or no such operation)
  Major opcode of failed request: 155 (GLX)
  Minor opcode of failed request: 19 (X_GLXQueryServerString)
  Serial number of failed request: 15
  Current serial number in output stream: 15

Hi Robert,

Can you make the 713643 as the parent and the other as the child. The reason
is because the first one contains lot more information about the bug.

Also, after installing the latest ATI driver for my graphics card from ATI website, the driver is not working.

Following error comes when i try to activate the ati driver from system->admin->hardware drivers.

sorry, the installation of this driver failed.
please have a look at the log files for details: /var/log/jockey.log

I am attaching the jockey.log file.

I have a similar--possibly the same--problem, worst with Firefox but also with other programs: Thunderbird, Rhythmbox, Chromium, Update-Manager. Whenever I open a new tab, do a task, or anything (scrolling just so happens to be a good way to trigger it as well) the CPU usage of the program and xorg (and any other processes connected to what I am doing) shoot way up above what they are normally at. This problem just started in the last half week, so I am inclined to believe that it is a regression from a recent update. If you think it might be the same bug I can post more information.
