Application to read current clocks of ATi Radeon cards (xf86-video-ati and fglrx)
C++ QMake

Simple application to read current clocks of ATi Radeon cards (xf86-video-ati and fglrx).

xf86-video-ati driver

Install and run radeon-profile-daemon ( for using this app as normal user. Otherwise app need to be run with root privilages for read clocks and changing profiles. You can add username ALL = NOPASSWD: /usr/bin/radeon-profile to your /etc/sudoers. Here is tip for run app as normal user but involves change permissions to system files:

Can be forced by --driver xorg parameter.

fglrx driver

Normal user can run it. Data is read from ati-config output. No support for power settings.

Can be forced by --driver fglrx parameter.



  • Qt4 or Qt5 (see build below)
  • libxrandr
  • radeon card

For full functionality:

  • glxinfo - info about OpenGL, mesa
  • xdriinfo - driver info
  • xrandr - connected displays
  • lm_sensors - temperature (no need if hwmon for card is present in sysfs and if catalyst is installed)



Qt4: qmake-qt4 && make in source directory.

Qt5: qmake && make in source directory.


  • "no values": Check /sys/kernel/debug. If it's empty, try # mount -t debugfs none /sys/kernel/debug
