    Exclamation uStudio 12.04 64 bit on Lenovo L420

    I recently installed Ubuntu Studio 12.04 64 bit on my laptop, installed all the updates, and started using it for basic stuff prior to using it for media production. Several issues have presented themselves, and I don't know what to do to proceed. Additional note: some of the problems mentioned below also happened when I tried to install regular Ubuntu 12.04 64bit.

    Sometimes when starting up, the boot hangs on the Ubuntu loading screen, never gets to the login screen.

    While using the computer, I have had several instances in which the computer completely freezes up. No keyboard or mouse input, including trying to switch to a TTY session (ctrl shift F1-6). I haven't tried it recently, but I think one time it locked up, I tried to connect to it via SSH, and it wouldn't respond.

    I cannot put the computer to sleep. Or more accurately, I can put it to sleep, but upon trying to wake it up, the speakers pop and the system restarts.

    When I try to restart the system, sometimes it will hang then, too. For instance, after I installed the updates, Ubuntu requested I restart the computer. I had to hard reboot it, because it got stuck.

    I very much miss Ubuntu/Linux, and I suspect Lenovo is to blame for a lot of my problems in the past year or so, but until I can get things stable, I can't use it.

    OK, wait, you can't just blame Lenovo for that.

    I think maybe your installation is corrupted. Or maybe even your installation media IS corrupted. Don't forget to verify the MD5 checksum of the ISO image. Use unetbootin to burn the image to your USB. Then install it again and see if it still has these problems.

    Also, you DID use the 12.04.1 images didn't you? Don't use the old 12.04 one.

    If then there is still the problem maybe it then WILL be Lenovo to blame for the hardware.

    I appreciate the prompt response.

    I checked the MD5 checksum of the ISO against the checksum listed online, and used LinuxLive to copy the image to my flash drive.

    The problems happened with Ubuntu 12.04 standard as well as with Ubuntu Studio, and obviously they share a lot of the same core system stuff, so having many of the same issues seems to point to issues with Ubuntu 12.04 [all variants] correctly interfacing with my hardware.

    As to which image I used, not quite sure, I grabbed it from the main site. Reviewing my downloads folder, it appears neither the standard or studio versions include ".1" in the version.
    By installing all the updates, should that take care of it, or should I re-install by using the updated iso?

    Ubuntu studio is ubuntu. There are no differences on system level, only on software selection (including the DE).

    I agree on that.

    You're wrong there. Ubuntu Studio uses a different kernel from Ubuntu Desktop. Ubuntu Desktop uses a generic kernel, whilst Ubuntu Studio uses a lowlatency kernel to enable rt.

    Re: uStudio 12.04 64 bit on Lenovo L420

    My purpose in mentioning both installs is:
    *I used two different ISO images
    *I installed Ubuntu twice
    To have a corrupt ISO and/or install twice in a row seems unlikely.

    By the way, for what it's worth, Ubuntu standard was installed with online access so it could grab updates, while uStudio was installed offline, with updates obtained after installation.

    Smartboyhw, after downloading all updates available, would my install be considered 12.04.1, or do I need to reinstall with a newly obtained ISO?

    I mention the Power Manager because of this:
    While using the computer, I have had several instances in which the computer completely freezes up. No keyboard or mouse input, including trying to switch to a TTY session (ctrl shift F1-6). I haven't tried it recently, but I think one time it locked up, I tried to connect to it via SSH, and it wouldn't respond.

    I cannot put the computer to sleep. Or more accurately, I can put it to sleep, but upon trying to wake it up, the speakers pop and the system restarts.
    From what I've read/heard, laptops and the Power Manager have had issues. To see what the PM does go to:

    AppMenu > Settings > Settings Manager > Power Manager

    If you want to disable it, from where you are in Settings go to the Applications Autostart tab and uncheck the box for Power Manager. Then to try it without rebooting at first, go to the Session tab and quit the PM there.

    Because you're on a laptop, I'm guessing you'll want to be aware of your battery level, and that's what the PM will display for you, so obviously you'll lose that function while you try this.

    Again, not being guru enlightened or anything, that's just what I would try
