Display settings reset on SLES 11 if screen is turned off

Hello,

I’ve got a problem with my display settings every time I turn my screen off.

My nvidia card is a Quadro NVS 295 from a [b]HP Z600 Workstation/b, using nVidia drivers 319.32-228.1 from ftp://download.nvidia.com/novell/sle11sp3/ . I’m using a screen Dell UltraSharp U3011 ( http://www.dell.com/ed/business/p/dell-u3011/pd ) with its display port and my graphic environnement is KDE on SLES 11 SP3.

Does anyone here know where the problem could be ? A person from SuSE told me it could be a problem with the drivers of nVidia.

Thank you.

Can you explain in detail? Please provide reproduction steps and nvidia-bug-report
