Description Ihar Hrachyshka 2011-03-04 10:22:16 UTC

I'd like to submit bug which I experience on one of the main Belarusian news sites when using their image switch function. Here is the link (in Belarusian): http://nn.by/?c=ar&i=51332

When you try to switch to another image by clicking into it, CPU becomes crazy (100% load) and firefox is hung for 0.5 min. With fglrx driver, there is no such problem, and images are switched smoothly and with graphic effect.

I don't know how to investigate the issue. If you need more info from me, just ask.

My system is latest Ubuntu 10.10.

xserver-xorg-video-radeon 1:6.13.1-1ubuntu5
xserver-xorg-video-ati 1:6.13.1-1ubuntu5

First of all, please attach your full Xorg.0.log and xorg.conf (if any) files and dmesg output, at least pertaining to DRM/AGP.

Then, it would be great if you could get a profile for the CPU usage using sysprof or oprofile.

Ihar Hrachyshka, Ubuntu 10.10 reached EOL on April 10, 2012. For more on this, please see https://wiki.ubuntu.com/Releases .

If this is still reproducible, it will help immensely if you filed a new report with Ubuntu by ensuring you have the package xdiagnose installed, and that you click the Yes button for attaching additional debugging information running the following from a terminal:
ubuntu-bug xorg
