Is that the case here? I don't know what exactly is a hybrid graphics... Do you mean that there are two graphic cards? It the case as far I can see: lspci -vnnn | perl -lne 'print if /^\d+\:.+(\[\S+\:\S+\])/' | grep VGA returns: 00:02.0 VGA compatible controller [0300]: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller [8086:0416] (rev 06) (prog-if 00 [VGA controller]) 01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Mars XTX [Radeon HD 8790M] [1002:6606] (rev ff) (prog-if ff) So, I can see that the integrated graphic card is in use, not the ATI card. I have two questions: 1- How to activate the ATI graphic card? This card is supported by linux for I bought that computer from Dell with ubuntu installed to be sure that the hardware is linux compatible and the ATI graphic was configured. 2- Why, as the ATI card is not in use, the radeon module is loaded by the kernel? -- François Patte UFR de mathématiques et informatique Laboratoire CNRS MAP5, UMR 8145 Université Paris Descartes 45, rue des Saints Pères F-75270 Paris Cedex 06 Tél. +33 (0)1 8394 5849 http://www.math-info.univ-paris5.fr/~patte
