I've recently installed Ubuntu 12.04 and I love it. However I have one problem- I am unable to shutdown or reboot properly.
When I shutdown my laptop (Acer Aspire 5560) it hangs on the 5 dots and stays there.
When I reboot my laptop it does shutdown but when it boots back up it stay's on the Purple screen (no logo what so ever)
Thing's I've I'd to stop this:
sudo service network-manager stop
before shutdown - nothingAdding some lines the the GRUB file - nothing
- installed other Ubuntu versions - nothing
sudo shutdown -h now
- nothing
and some more.
At the moment I see a black screen in front of me with the text
Asking all remaining processes to terminate [OK]
And the 5 dots with only the last one orange.
On other tries I got this thing:
modem-manager:could not get the system bus......
I first had Ubuntu dual boot Windows. And then it worked fine. However after a fresh install of Ubuntu alone I got this.
I had a similar problem with a Dell XPS 15z which I resolved by adding
acpi=noirq
to the kernel arguments:set
then
Note that previously I had been using
acpi=off
, which permitted me to boot, but not shutdown. Without any acpi flag, I was not able to boot.You may try to these commands into terminal
For shutdown:
For shutdown:
For restart:
For shutdown:
For hibernate:
I got a hack from this link -- http://www.pbehnke.com/main/node/11, for some reason if the usb controls are set to
auto
, the shutdown-reboot loop starts. The solution was to make themon
forcefully.I have added a function in the
/etc/init.d/halt
script like this --and I call it before
do_stop
incase $1
stop
switch --Now the machine shuts down.
The only thing that I needed to do was to press Ctrl+Alt+T to open the terminal. When it opens, run the command below
and now it's working fine.
Same issue with spurious hangs "on the 5 dots". I've read somewhere (cannot remember where) to first "Log Out" (top right corner menu) and then shutdown. I've been doing this for more than one month now with no more issue.
I'm no expert but i loaded BARTpe to get to a command promt and reinstalled bios it booted straight to the hard drive guess it couldnt see it just try to load default in your bios might not have to update
I realize this is a super old post, but I found the REAL answer for this model. It's not Ubuntu, it's the Aspire.
From the ubuntu bug registry: (link)
A user on TomsGuide confirms this is the case even when installing Windows:
Again from the bugs page a workaround: (link)
Lot's of work to fix such a small thing. Some users have suggested that a BIOS update my help.
DISCLAIMER: I cannot confirm any of this outside that the error occurs, and that windows does indeed experience the same issues when installed with gpt. If I do decide to follow the workaround (very risky) or update the BIOS (even more risky) and get some further results I'll update.
