Sorry Andy, I forgot to report here. The problem is solved for me since yesterday (maybe it was on Tuesday).
1/ Display corruption. Solved with latest usplash packages I guess. 2/ "power off" issue. Not a kernel issue at all. Magic SysRq were working, I just typed them wrong (no need to press the Fn key to activate the SysRq key on my Lenovo T61)... Sorry. Solved with latest upstart or boot/shutdown related scripts/programs. -- Notebook HP HDX18-1080eg does not "power off" after shutdown since kernel 2.6.31-13 https://bugs.launchpad.net/bugs/450457 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
