[Bug 415023] Re: brightness is broken on MSI WIND U100

[Kychot]

Long time I did not upgrade from Ubuntu 10.10 because of the workaround
of this bug I used was simple: To click on "Applications" icon in the
Gnome panel when the screen flickering occurs. But this workaround does
not work on the Ubuntu 11.04 or higher. But the reliable Ubuntu 10.10 is
not supported now so the upgrade is necessary.

So now when upgrading to Ubuntu 12.04 the flickering continues and I
didn't find another workaround to fix it. Even if I choose the old Gnome
environment and not Unity.

I have the Czech netbook "Mivvy m310" which is the clone (branch) of the
MSI Wind U100 but its HW and also BIOS is not fully identical to the
original MSI netbook and the manufacturer of the Mivvy  strongly not
recomends the BIOS upgrade using the original MSI BIOS.

What should I do? Most workarounds in this thread are obsolete and not
working for Ubuntu 12.04. So from my point of view this bug is not fixed
yet.

Probably this bug occurs now not in the gnome-power-manager but in
gnome-settings-daemon. The only workaround I found is to find the ID of
this process and kill it:

ps aux | grep  /usr/lib/gnome-settings-daemon/gnome-settings-daemon
kill -HUP id

The flickering vanishes, the daemon restarts itself but sometimes some
other parts of the GNOME environment are injured (for example some icons
on the panel, the background color etc.) But in all cases there is no
way to control the brightness of the LCD – it remains the same i.e. low.
So the netbook is usable in the darkness only.

I attach the screenshot: see the flickered brightness icon on the right
upper corner. The icon on the top of the left panel shows that the load
of processor goes to the maximum. And the icon of the CPU1 frequency
(the 3-rd from the top on the left panel) vanishes.

I think this bug should be again reopened.

Bug description:
  Binary package hint: gnome-power-manager

  Versions : karmic up to date (08-17-09) with gnome-power-manager
  version 2.27.5-0ubuntu2

  What should happen : brightness should not flash.

  What happens :

  Brightness changing seems broken on my MSI wind U 100.

  First in GDM it starts flashing for a good 30 seconds and then the
  same problem happened when the Gnome session begins.

  Whenever I try to  manually change the brightness  a bit too fast
  (using the sliders or the keyboard) it start flashing again.
