Public bug reported: Binary package hint: xorg
this is a two graphic cards, three monitors setup. I've been using this now for many years with ubuntu. After the update to ubuntu 11.04 the entire GUI experience is extremely slow and lags. This behaviour even occurs with the 'ubuntu standard no effects' desktop session! very annoying. If I drag a round a gedit window for example, the xorg process (as visible in 'top') will use up to 99% of my CPU power. Anyway, since the standard desktop was just working fine with the previous ubuntu versions, I would expect the latest one to work just fine too.
