Not sure if mine is exactly the same issue: Maverick 64 bit, ATI graphics card
Suspend and hibernate worked on 10.04. Following upgrade (clean install) failed to resume from suspend and hibernate. pm-log indicated success, computer powers up, but display is blank. Could successfully suspend/hibernate and resume from recovery console using pm-suspend/hibernate. Adding radeon.modeset=0 meant that suspend and resume now work.... But this messed up my dual monitor configuration and had to create xorg.conf file. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/434956 Title: screen backlight off after resume-from-suspend when using ATI KMS -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
