I am experiencing instability which seems to be related to my video drivers. I have an HD 6970 video card and am using Ubuntu 13.10.

  • If I use the open source (radeon) driver, the card runs hot (>70C idle) and the fan is very loud.
  • I tried enabling DPM with the radeon driver, and it helps somewhat with the heat/fan issue (still not as good as the proprietary drivers though), but the system becomes instable during use, for example I could be browsing the web and the screen turns black/dark blue and I need to reboot.
  • When using fglrx/fglrx-updates, I have an issue where sometimes after my monitor goes off and I wake it up, the screen is black except a thin streak of white at the top of the screen. I can then only hard reboot.
  • I tried installing the drivers directly from AMD, but had the same issue as with fglrx (problems getting the monitor on after it shuts off)

I dual boot with Windows 7, and have had no problems with stability when using that OS.

I'm not sure what else to try. Any suggestions would be greatly appreciated!
