I am running Jaunty 64bit (Thinkpad T500 with GMA 4500 integrated intel grpahics) which I installed during the testing period last year. Since then something happened to my intel xorg drivers and, basically, they don't work (garbled screen, regardless of xorg.conf settings) and I am stuck using the vesa drivers. Everything works from a live usb, including 3d acceleration, but I don't want to have to reinstall!
How can I perform a complete reconfiguration of xorg so that it completely resets its files and drivers to default? Which packages must I remove/reinstall to achieve this?
Thanks very much in advance.
