Suddenly lost Display2 in 2 screen-setup

Hi!
I’ve been using OpenSUSE 13.1 64bits since it came out in release.
I use a HP Elitebook docked with 2 external monitors;

  • Display1(Right monitor) DisplayPort
  • Display2(Left monitor) DVI

Gfx:

  • AMD Radeon HD 7500M/7600M Series
  • Driver: AMD v14.301.1001-140915a-176098C
  • 2D: v14.30.4
  • Catalyst™ Control Center Versjon: v2.21
  • RandR-versjon: v1.3

Suddenly i lost Display1.
When i turn on power, both screen is working until login-screen, then Display1 is shutting down to Power-saver…
It seems like the system detect the monitor, but no gfx-signal is sendt to it.
If i choose to Shut down, the shut-down screen shows on both monitors, so there is no HW-fault in Display1.

Has AMD relased a new driver that has been updated during System-update, that cause this problem?
