Screen resolution problem

[gfs]

Starting 3.9 with screen-1280x1024 has a problem.
The startup screen shows that mode 1280x1024 is recognized but the Control Center Dsiplay shows that the max resolution is set to 1154x864.
In other linux versions I could solve this by using kconfig but that program is not included on this knoppix.
Anyone have a solution???

Problem solved.
I was typing kconfig instead of kxconfig.
