Title:
Desktop brightness minimal after upgrade 12.04 -> 12.10 on Acer Aspire
One D270
Status in “xorg-server” package in Ubuntu:
Expired
Bug description:
Hello,
On Acer Aspire One D270 netbook (please see full hardware
configuration here http://h-node.org/notebooks/view/en/536/Aspire-
One-D270--ZE7-/1/1/undef/undef/undef/undef/undef/undef/undef/D270),
desktop brightness is reduced to minimum after upgrading from 12.04 to
12.10.
Netbook's video card is this: http://h-node.org/videocards/view/en/538
/Intel-Corporation-Cedarview-Integrated-Graphics-Controller--rev-09-
The function keys for brightness (Fn + horizontal arrows) APPARENTLY
work: they DO present a brightness slider when pressed, but brightness
is not decreased/increased when sliding left-right.
The upgrade was done in an automatic way (via GUI update manager, who
offers a new version of Ubuntu).
After some Google searches, the fix presented here, comment no. 9
(adding some parameters to the kernel line while booting) applied,
solving the problem: http://askubuntu.com/questions/3841/desktop-
doesnt-remember-brightness-settings-after-a-reboot
This seems to be an old bug, still unsolved.
However, the correct video configuration should be automagically
detected at boot, WITHOUT manual user intervention and hacking (this
may be a serious stop for non-technical users buying an Ubuntu netbook
from consumer stores, especially since Acer is pretty popular).
Best regards,
Răzvan
