[Bug 19976] New: RadeonHD: high HD3650 power usage
http://bugs.freedesktop.org/show_bug.cgi?id=19976 Summary: RadeonHD: high HD3650 power usage Product: xorg Version: 7.4 Platform: x86 (IA32) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Driver/radeonhd AssignedTo: lverhaegen@suse.de ReportedBy: niella@telkomsa.net QAContact: xorg-team@lists.x.org Created an attachment (id=22623) --> (http://bugs.freedesktop.org/attachment.cgi?id=22623) lspci Hi, I have a Lenovo W500 thinkpad. When I use fglrx in Xorg my laptop only consumes 15-16W, but fglrx is so unstable that it crashes on logout, and I despise using it. When I use the OPENSUSE 11.1 radeonhd driver, I have much improved stability (although no acceleration), but power usage also jumps to 35W! I have tried xorg-x11-driver-video-radeonhd-1.2.4_121202_4e89726-1.5 and even the latest xf86-video-radeonhd git version but they all behave the same. Interestingly, when I'm not in X I also have high power usage, whether or not fglrx or radeon modules are loaded or not. I suppose the graphics card is not running in low power modes without fglrx. The only way I can get low power usage is through using fglrx in an Xorg session... I have even tried the radeontool tip mentioned here - http://www.phoronix.com/forums/showthread.php?t=6522 - but it made no difference. Any ideas would be appreciated! cheers Niel -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug. _______________________________________________ xorg-team mailing list xorg-team@lists.x.org http://lists.x.org/mailman/listinfo/xorg-team -- To unsubscribe, e-mail: radeonhd+unsubscribe@opensuse.org For additional commands, e-mail: radeonhd+help@opensuse.org

No powermanagement yet. Depending on your hardware, the fan might run at full speed. This turned out to be really tricky.

Power-management is one thing, but initializing an adapter so that is actually usable should be another, right? It's not just the fan I think, I think the clock-speed is running at max too. I guess I'm hoping someone has had a look at the specs ATI published and will be able to recommend something... cheers Niel -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug. _______________________________________________ xorg-team mailing list xorg-team@lists.x.org http://lists.x.org/mailman/listinfo/xorg-team -- To unsubscribe, e-mail: radeonhd+unsubscribe@opensuse.org For additional commands, e-mail: radeonhd+help@opensuse.org
