Hi zdenek.zikan,

This bug was reported against an earlier version of Ubuntu, can you
test if it still occurs on Lucid?

Please note we also provide technical support for older versions of
Ubuntu, but not in the bug tracker. Instead, to raise the issue through
normal support channels, please see:

    http://www.ubuntu.com/support

If you are the original reporter and can still reproduce the issue on
Lucid, please run the following command to refresh the report:

  apport-collect 455592

If you are not the original reporter, please file a new bug report, so
we can work with you as the original reporter instead (you can reference
bug 455592 in your report if you think it may be related):

  ubuntu-bug xorg

If by chance you can no longer reproduce the issue on Lucid or if you
feel it is no longer relevant, please mark the bug report 'Fix Released'
or 'Invalid' as appropriate, at the following URL:

It was bug that didn't happen every time, so it was difficult (or impossible) for me to reproduce it on Karmic. On Lucid Lynx, it's definitely impossible to test it, because there suspen-to-ram doesn't work for me any more. :-(
(I need to file a new bug when I gather necessary information about it.)
