CxOrg Posted March 19, 2012 Report Share Posted March 19, 2012 (edited) Most things work nicely on this little laptop with the AMD brazos e450 processor/GPU. The thing which has always proved troublesome is suspend to ram. Suspend works but it would never wake up requiring the battery to be removed to get it going again. Suspend to disk always worked fine. Hoping that updates from AMD/ATI for the video driver or new kernels would eventually solve it. I now have a MIB sourced kernel http://mib.pianetalinux.org/MIB/2011.0/32/projects/kernels/3.1.6/ and the latest ATI driver http://www2.ati.com/drivers/linux/amd-driver-installer-12-2-x86.x86_64.run which work really well making for a pretty reasonable video and desktop performance with all the KDE plasma effects and animations. However suspend/resume still did not want to play? I tried re-compiling the kernel which for a brief moment seemed to allow suspend/resume having read this solved someone's resume problem from one source. Finding a comprehensive guide for Suse linux which explains all you need to know about pm-utils and s2ram - http://en.opensuse.org/SDB:Suspend_to_RAM and here http://old-en.opensuse.org/Pm-utils Testing to find the best parameters to use with the Asus 1215B and ATI video driver I settled for s2ram -f -a 2 To make it work with the keyboard and power saving system I added this file /etc/pm/config.d/modules containing a single config line: S2RAM_OPTS="-f -a 2" set the permissions to 755 So far this works OK. I'll have to test against some other kernel(s) and use suspend to ram daily to see if it breaks? Edited March 19, 2012 by CxOrg Quote Link to comment Share on other sites More sharing options...
