Number of bugs in Ubuntu 13.04

[Gabor Toth]

I have been running 12.10 and it was very stable for me.  Then recently
upgraded to 13.04 and while the upgrade went well and I like the new
stuff and changes (not a lot, but still nice) there a number of bugs
which I was a bit startled about and did not know what bug report to
file or how to go about reporting it.  I have some time I could spend
helping on the fixing of these and thus please feel free to shoot at me
things that I should do to provide more data or test things and so on. 
As a general data I am running UBUNTU 13.04 on a Dell Inspirion 17R with
4 Gb RAM.  I also have an external screen, an LG small flat screen TV
connected through HDMI.  Here is the list:

 1. Since installation the system froze up entirely 3 times.  The last
    time I had Google Chrome, GIMP, Libreoffice Writer open and I was
    just talking on Skype.  The whole system froze but I could still
    continue speak on Skype - it was weird.  Nothing worked from there. 
    The mouse moved, but no response to clicks.  Tried Ctrl+Alt+F1 - no
    response, beside some hard disk activity, but no change on the
    screen.  Then tried Ctrl+Alt+Del a number of times and beside some
    hard disk activity, no change - or actually the mouse cursor have
    disappeared.  Had to do a total hard shutdown with the power button
    kept in for 5 sec.  The system started up normal after.
 2. Not sure if related to the above, but two times I had a problem with
    shutting the system down.  I clicked on shut down however during the
    shut down sequence the system froze or at least did not continue. 
    The "dots" kept moving like something is still happening, but no
    hard disk activity, nor anything for a long time.  Once by pressing
    Ctrl+Alt+Del I managed to get the system to restart and then could
    shut it down properly but the other time I had to use the power
    button to power off.  Weird.
 3. Once I had a problem to start the system up.  The graphical screen
    disappeared and only some text was left on the screen, seemingly
    frozen.  Then I switched to text mode with Ctrl+Alt+F1, that worked
    and immediately back to graphical (F7) and I got the graphical login
    screen and all went fine.
 4. There seems to be a bug with the sound system.  Originally it worked
    fine except the fact that I could not direct the sound to the
    external screen through the HDMI cable.  Seemingly the sound did not
    recognize that it is there.  Then sometimes after powering the
    system up I only gout a "Dummy Output" and no sound at all.  I
    Googled it and found a solution of re-installing the Alsa sound
    system and that stabilized the sound, it works all the time now, but
    still no way to use the HDMI output.  I am getting a scratchy sound
    when Skype starts but later on the call sound quality is perfect and
    also playback sound from all sources (Youtube, Banshee, etc.) are good.


These are the stuff that came with the upgrade to 13.04.  Previously on
12.04 and 12.10 the system was working fine and stably and would like to
put some work into making it again that stable - need some directions
though.  I can file bug reports or attach files or anything needed and
help out on the testing just need some directions.

Thanks a lot.

Best,

Gabor
