Thread: Task-switching always slow after reboot

hi there,

i'm absolutely new ubuntu. i've had experience various linux distros before, far administrative work i'm pretty absolute beginner.

installed natty via cd. pretty standard stuff. found task switching excruciatingly slow, 2 seconds alt+tab, or min/max window.

searched around , found it's common problem , did find, tweaking relevant ccsm settings (e.g. manually set monitor refresh rate, uncheck sync vblank, remove delay on static application switcher, other things i've forgotten). none of seemed work. kept playing , problem seemed resolve magically - doesn't persist.

solution i've found enable metacity compositing, reboot, , disable metacity compositing. via command line, looks this:

code:

gconftool-2 -s '/apps/metacity/general/compositing_manager' --type bool true gconftool-2 -s '/apps/metacity/general/compositing_manager' --type bool false

then, alt+tab near instantaneous. thing i've found work, problem returns if reboot machine. if enable , disable compositing manager without rebooting again inbetween, stays slow. if reboot, slow until disable manager. it's bizarre.

question two-fold:

1. why , sequence of steps work? i'd understand.
2. there can make fix permanent? don't plan on rebooting machine often, still annoying.

help!

edit: i've found isn't rebooting causes - logging in , out same. logging in , out between enabling , disabling metacity compositing manager fixes issue (temporarily, original case).

edit again: should add using classic, not unity isn't supported hardware.

1. reason compositing turning on every time login.

2. @ least temporary fix create script commands , add autostart.

script, disable_compositing.sh

code:

#!/bin/bash    gconftool-2 -s '/apps/metacity/general/compositing_manager' --type bool true  gconftool-2 -s '/apps/metacity/general/compositing_manager' --type bool false

then navigate wherever saved , make executable:

code:

chmod +x disable_compositing.sh

then add autostart (i believe in system->preferences->session don't use gnome, may have search little bit location.)
