Hello, Sorry to answer so late. I tried on Lucid and the problem continues to be present, even if it is not so persistent as in previous releases. I made a little video in youtube, so you can see what I mean. At the moment I've uninstalled Lucid and come back to Hardy (which supports proprietary driver fglrx for ATI Radeon X1600 and does not present the problem). In Hardy with proprietary driver, the image is fine and stable.
Here is the video: http://www.youtube.com/watch?v=0rnvc5UElNU If you need to know also which is the monitor, here what it is written on the sticker: HP w22, HSTND-2241-T, product number RG556AA, assembled "January 2007, 434000-001, CTM003". But I think the problem is in the open source driver for radeon. I tested again with a live cd of Lucid Kubuntu and it seems to me that some applications give more troubles than other ones. In particular, I got almost any trouble with konquerror or firefox, but it is impossible to work, if I have xchat maximised (the size of the window seems also affect the problem). I used a live disto because I wouldn't like have to reformat the partition to downgrade twince. Btw, I typed "apport-collect 498736" in a terminal to update it in Lucid. Yours Sincerely.
