Configuring

aticonfig

Since version 8.18.6 the fglrx driver includes the aticonfig tool which simplifies xorg.conf editing. Here are some useful commands this tool offers (for a complete list see aticonfig --help).

FIELD_MESSAGE_calamonel

Changes will not change the config file.

Print information about power states.

aticonfig --list-powerstates

Or, for us lazy folk, the shorter version is aticonfig --lsp

Set a power state to the lowest (battery friendly)

aticonfig --set-powerstate=1

• Note: check out available power states using aticonfig --list-powerstates
• Note: this option does not work when an external monitor is connected

Print information about connected and enabled monitors

aticonfig --query-monitor

Examples how to enable two monitors on the fly

• Assume you have two monitors already setup correctly (Dual monitor support at Ubuntuforums)
• This example enable laptop internal monitor (lvds) and external monitor (crt1)

aticonfig --enable-monitor=lvds,crt1 --effective=now

• Note: aticonfig --enable-monitor=STRING,STRING where STRING can be one of the following set, separated by commas: none,crt1,crt2,lvds,tv,tmds1,tmds2,auto.

Only 2 displays can be enabled at the same time. Any displays that are not on the list will be disabled.

• Note: check out connected and enabled monitors using aticonfig --query-monitor

Turn off the second monitor on the fly and start to use only laptop internal monitor (lvds)

aticonfig --enable-monitor=lvds --effective=now

Swap monitors on the fly when using big desktop mode

• Assume you have two monitors already setup correctly (Dual monitor support at Ubuntuforums)

aticonfig --swap-monitor --effective=now

• Note: This only works for big desktop setup. This will swap the contents on the two monitors.
