Hi,

I have noticed that when I log out of Mandriva, and then end Current session, my monitor enters sleep mode and my base unit stays switched on. I try coming out of sleep mode by moving mouse, touching keyboard, even pressing power button to kick it back to life, but nothing, i have to hold down the power button on the unit to turn my machine off.

Any ideas what could be causing this? This has only happened since i did a clean install of Mandriva last week. Mandriva One is the only OS on my system. any help would be appreciated.

Hi Barry - as no-one has replied to your question (probably because we don't know the answer!) I'll have a go. What make is your monitor? This could actually be a bug, because I haven't heard of this problem before.

I wonder if this could relate to your power management settings?

Add the line to /boot/grub/menu.lst:

acpi=force

where the 'kernel' line ends at. Give a space first!

So that your line which looked like this:

kernel          /boot/vmlinuz-2.6.22-14-generic root=UUID=878f5580-5217-4cbf-81df-a9ced38b88ed ro quiet splash

now looks like this:

kernel          /boot/vmlinuz-2.6.22-14-generic root=UUID=878f5580-5217-4cbf-81df-a9ced38b88ed ro quiet splash acpi=force

hi guys, sorry i never got back to you sooner. It seems the issue has resolved itself for the time being. I havent had a problem with the last couple of shutdowns. However I will keep the post open for now incase it re-appears. If it does i will give your advice a go.

I will try the ACPI thing to see if it works, but my problem is that I have a laptop (HP Pavillion tx 1410) and when I restart (and possibly also when I shut down) it hangs just before it shuts off. I tried hitting escape for verbose, but the computer was frozen. I tried doing it sooner, but I got the same problem. i'll try it immediately this time to see where it hangs. Is there a log I can look at to help figure out why my computer is getting confused?

I had a common bug in Ubuntu and each time I install it, the first modification is the GRUB file only. To get a log, run these commands and post their output:

------------------------
lspci -vv > lspci-vv.log
lspci -vvn > lspci-vvn.log
dmesg > dmesg.log
lshal > lshal.log
-----------------

Don't panic if these don't work, try 'su'. If still not, remember I have blindly copied them from:

https://bugs.launchpad.net/ubuntu/+s....15/+bug/43961

where there is a long long thread for the same issue.

............And before you do anything I was blathering about, try this page:

It says it is not a fault of Ubuntu team (nor Mandriva as in your case).
