Proprietary AMD graphics drivers for Linux

How do I start Catalyst Control Center (CCC) from bash

I created a demo user to test my X server config and ATI graphic driver. I run into a problem that my user didn't have relevant permissions to run commands with sudo. Every time I tried to lunch the Catalyst Control Centre I got a popup windows asking for password to perform administrative task.

Solution

1. The name of the program is displayed in the popup windows: amdcccle
2. If you didn't notice you can find this using these methods

$ dpkg -l | grep ati | egrep -iv 'configuration|application|automatic|compatible|compatibility|static|foomatic|ating|ation|ative' | grep ati
$ dpkg -l | grep amd

$ dpkg -L fglrx-amdcccle | grep bin
/usr/lib/fglrx/bin
/usr/lib/fglrx/bin/amdcccle
/usr/lib/fglrx/bin/amdxdg-su
/usr/lib/fglrx/bin/amdupdaterandrconfig

How do verify that my driver is loaded

More checks can be found in [1]. As a simple check you can run:

$ lsmod | grep fglrx
$ dmesg | grep fglrx

Execpt CCC what command can I used to list, print and change the graphic driver settings

You can use a command 'aticonfig'.  Example output can look like this:

$ aticonfig --lsa --odgc
* 0. 06:00.0 ATI Radeon HD 5700 Series

$ aticonfig --odgt
Default Adapter - ATI Radeon HD 5700 Series
                  Sensor 0: Temperature - 37.00 C

$ aticonfig --odgc
