I'm very new to Ubuntu and this site as well. I've grown up on Windows and felt like trying something new. So here is my problem: I have a DELL Inspiron m5030 that got a virus so i reformatted and re-installed Windows but I guess the virus may have still been in there because my laptop still ran very slow and I ran a malware scan and it found some things even right after a factory reset.
So I decided to download Ubuntu 12.04 LTS, install it via DVD and chose the option to fully replace Windows. Everything seemed to work fine, no errors popped up and wile it was loading I could connect to my wifi and set up my user name and password. Once it was finished I tried logging in and it would just freeze when I hit enter after entering my password at the log in screen. I could still move my cursor around but no buttons or clicking did anything. I've tried re-installing and the same thing happened. So I've tried installing again but this time I've selected the option to auto-login. Then when I would reboot or power on it would just leave me at a blank screen.
I searched around on the web to find a solution and I found something that said when booting up hold the Shift key (getting to GRUB?), hit E, replace where it says something like
quiet splash with
acpi=off and then hit Ctrl+X.
That seemed to work and that is where I am typing this now. BUT now I have no little battery icon at the top left and no way of checking my battery status or charge. I also must replace the
quiet splash with
acpi=off everytime I reboot or power on. Also when I power down it gets stuck at a screen with some text and the last thing it says is
3168.221823 system halted. So then I must manually hold the power button to power off.
I'm sorry this is so lengthy but I tried to be as descriptive as possible so maybe I can find a solution.
