Using an old mx200 128Mb AGP card. Log in ok. Sometimes the top and bottom bars do not appear, sometimes one sometimes both sometimes none. The menus on firefox/thunderbird and others disappear when I move the pointer from the menu heading to the menu itself. I can't play you tube videos, nor pacman, so the world has ended as I know it.

If I type sudo metacity --replace in a terminal the window manager seems to work fine. But I don't know how to make this permanent. One option was: System menu>>preferences>>sessions>> In the sessions tab make sure that "automatically save changes to session" is checked. I don't have a sessions option in the preferences menu. So...? Must be a line of code in a terminal I can use to get round this.

I have not upgraded to Ubuntu 11... because the graphics card is so old that I cannot get any decent screen resolutions when I do. On 10.04 I disable the Nvidia driver for the same reason and use 1024x768. Ta
