Thread: System unusable after 8.10 -> 9.04 upgrade

-

i upgraded laptop 8.10 9.04 last week, , system unusable in kubuntu now. mouse response poor , system lags terribly when try anything. can log in applications unstable least. firefox , konqueror crash regularly , render pages unreadable due horrible video flicker. konsole window takes 10 seconds come , has absurd delays of own.

when run 'top' see xorg taking vast majority of cpu - 95% or more. leaving system running overnight not improve. tried 'sudo apt-get update plasma' thinking perhaps fact plasma not showing on top might telling me something; did not help. tried 'sudo apt-get update xorg' , did nothing.

there way either re-install or un-install 9.04 upgrade? system fine in 8.10 after seeing improvements of 9.04 upgrade on desktop thought worthwhile upgrade on laptop.

laptop in question has 1.6ghz p4m 2gb of ram, , radeon mobility video card.

i have noticed response normal on ssh connection in laptop; unusable when using directly...
