Hi list I use a script to switch between my graphic cards on startup and shutdown. there are a atu Radeon HD 5650 and an intel integrated card, because of heating problems that made my gpu fan stuck, i always switch off that radeon card on start up, but due to some problems that other people reports about highspeed fan in boot time, i always use the script to bring the radeon card back on when i shot down my laptop. i don't know what i explained above is relevant but every time i boot up again after power off the system with the script i get this error in my screen: [drm:ironlake_update_pch_refclk] *ERROR* enabling SSC on PCH if i don't use script to shut down, I get a clean boot up. what does it mean? some serious problem exists when i boot up to my windows box with intel card (it shows BDOS after two or tree minutes) that makes it almost impossible to run windows on battery power for me because it automatically uses intel graphic card and eventually get to BDOS state. is it a hardware problem or just a driver fault? (I like to mention that my Radeon GPU fan doesn't work at all but with radeon card being off i don't have any heating problems) -- Shahab Shahsavari Alavidjeh ----------------------------------------- شهاب شهسواری علویجه ـــــــــــــــــــــــــــــــــــــــــــــــــــــ Weblog: http://piamak.wordpress.com Twitter: http://twitter.com/zzgraph ==================== -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
