Question Does anyone know the HorizSync + VertRefresh values for Acer Aspire One D255?


I don't know if it makes any difference but my exact model is:
Quote:
Acer Aspire One AOD255-N55DQkk
I'm trying to configure X without the help of HAL and message bus. In other words, I'm configuring X in the good old fashion way by using xorg.conf.

With hal and messagebus turned off, X just freezes - keyboard, touchpad - everything. The screen looks ok in fact, but to write an xorg.conf file to fix the problem I will need the H+V values.

Looking at other distros installed on Acer Aspire One D255 netbooks WITH hald doesn't help - they don't use xorg.conf.

If you know where Windows7 stores this data, then I could try and look there.

Needless to say I've looked on the Acer site - useless.

found this marketing hype...

ref. http://cache.inkuiri.com/stores/sado...py-linux-resmi
Code:
Display 10.1" SD 1024 x 600 (WSVGA) pixel resolution, 
high-brightness (200-nit) LED-backlit TFT LCD

Graphics Intel® Graphics Media Accelerator 3150 (Intel® GMA 3150), 
with 64 MB of dedicated system memory, supporting Microsoft® DirectX® 9

Dual independent display support 16.7 million colors 
External resolution / refresh rate:
VGA port up to 1600 x 900: 60 Hz
1600 x 900: 60

for example, refresh ranges /etc/X11/xorg.conf
Code:
HorizSync 31.5 - 64.3  #kiloHz
VertRefresh 50.0 - 70.0 #Hz

I wonder if this might help?

edit,
also this fine article has some more tricks to find the res...
Code:
To see if your display size and DPI are detected/calculated correctly:

$ xdpyinfo | grep dimensions
$ xdpyinfo | grep "dots per inch"
ref. https://wiki.archlinux.org/index.php...nitor_settings

the next couple of paragraphs describe how to workout different aspect ratios.

Cheers

Thanks alot, GlennsPref

I was only thinking I could only get the info from Acer etc. instead of looking on the netbook itself for the info - I was doing too much searching and not enough thinking

Those links have been really useful.

Thanks again.
