Hi I've found at all Xfree86 versions that I could install the same error : Fatal error : Negative sized edge ??? When the server crashed, after I start any application window, like konqueror, mozilla, etc .... The X works fine ....clean and the mouse works ..... I've been used a Savage4 16 Mb AGP and the agp device works fine at linux ....the version are from 3.3.6 until 4.1.**( I don't remember !!!) Will be nice if anyone that had this problem can make it clean to me ... thanks in advance .. -- Celso Providelo cprov@iris.sel.eesc.sc.usp.br Linux user #166906 LAMI-Laboratories of Microprocessors Department of Electrical Engineering University of Sao Paulo (USP - Sao Carlos)
