Comment 344 for bug 415023

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.
