I have also had this problem for quite some time. What seems to happen is that I select suspend or hibernate and the system will not go to sleep – the fans continue to whirr. I have actually gone back and tried some old Ubuntu Live CDs and it seems that up to Ubuntu 7.04 it used to be possible to send the system to sleep so that the fans were off.
(However, I have not been able to wake those live-CD systems from their sleep, but this may be another issue and may have more to do with the fact that I only tried this with live CDs, and sometimes, when suspend/hibernate commands were unavailable on the Live CD menus, I have used the `pmi action sleep` or `pmi action hibernate` or `pmi action suspend` commands to see if I could put the system to sleep there – so I wouldn't focus too much for the moment on the fact that I was unable to wake the old Live CD systems and focus on the fact that I was able to send them to sleep.) Again, up to 7.04, I could send the Asus P5N-E SLI system to sleep, but from 7.10 right up to the present I can't. I then did a `locate asus` on the 7.04 and 7.10 live CDs to check for differences (see attachment). I think the keyboard-related thing and pegasus things in there can be disregarded, but I did notice two interesting things: 1. *Both* systems still have the asus_acpi.ko module which is absent in 10.04 LTS and newer versions (and probably some other older versions too). The removal of asus_acpi.ko, apparently –I'm guessing here– in favour of the newer asus-laptop.ko had long been my prime suspect, and I had been intending to try to reinstall the old asus_acpi.ko on a newer system, but apparently that's not the problem, given that suspend does not work on 7.10 either, even though that version has asus_acpi.ko. 2. What 7.04 does NOT have but that 7.10 does have is this file: /usr/share/hal/fdi/information/10freedesktop/20-video-quirk-pm-asus.fdi The ASUS P5N-E SLI is not mentioned in that file, but I'm wondering if that file plays a role? I even tried editing the file (as root, natch) and introducing sections for the P5N-E SLI, but IF indeed this is the issue and IF it is a matter of just getting the right combination of parameters set in there, then I have not been able to figure out what the correct parameters are. I have run dmidecode, but I'm having some difficulty translating the dmidecode output into the syntax used in the .fdi file. I do not really know what I'm doing. Help from someone who knows about .fdi files etc. would be very appreciated. ** Attachment added: "locate asus on 7.04 and 7.10" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/980083/+attachment/3155345/+files/locate%20asus%20comparison%207.04%207.10 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/980083 Title: Suspend Fails on P5N-E SLI To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/980083/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
