netbook-launcher is confused about the location of the pointer

[Paganini]

Binary package hint: netbook-launcher

After upgrading to Jaunty yesterday, netbook-launcher is no longer usable on my Thinkpad X40.

I see lots of posts about slow / erratic pointer movement. However, my pointer *movement* is fine; netbook launcher just doesn't seem to know where the pointer *is.*

Expected behaviour: When floating the pointer over a launcher icon, the icon highlights. clicking the launcher icon starts the associated program.

Observed behavior: Lots of icons highlight erratically as the pointer moves. These icons are not the icons that are under the pointer, but are far away from it. Clicking an icon frequently does nothing, or even launches the wrong program, because netbook-launcher thinks the pointer is someplace else.

Can confirm the same behaviour on an Asus S52. Screen resolution is 1024x768. On my Thinkpad T43p it is working fine.

I downgraded the Intel driver to the version used in intrepid using the guide at https://wiki.ubuntu.com/ReinhardTartler/X/RevertingIntelDriverTo2.4, and that resolves the issue.

Thanks Harald! This workaround helped me.

Good, I am glad it help.

I think it is related to the performance of the video card driver
though, because my laptop is still not very responsive and xorg is using
a lot of cpu. How is it working on your machine. I believe you might
have the same video card, Intel 855GM. Do you have the same kind of
problems on your system?

If so, some possible solutions can be found at

I don't have time tonight, but I will hopefully get to try some of these
solutions tomorrow. (The problem is on my wife's laptop).

Hi Harald,

My thinkpad X40 does indeed have an Intel 82852/855G graphics adapter. I thought I had included that information here, but I guess I forgot. After reverting to 2.4 drivers things do seem a little sluggish, but I did not notice a major performance hit. However, I didn't try to do anything too intensive. Later this evening I will try watching a video on it and see how it does.
