>== How can I use the viafb framebuffer drivder? ==

When activating it, the screen fades to white and is completely unusuable. I managed with some options to just black out.

How can I actually get it to work? -- Svenska 10:05, 4 September 2009 (UTC)

How to have different resolutions on VGA & LCD ???

Did anybody get different resolutions (ex. LCD=800x480 and VGA-output=1280x1024) on the A110 ?

Please provide the xorg.conf file and what tool is used to modify the resolutions !

800x480

well done! :-) First time I see the wiki in 800x480 :-) --Andreas 17:16, 4 June 2008 (UTC)

DisplayHardwareLayout

The only option needed for experiments is: 

Option "DisplayHardwareLayout" "TTLLCD"

So far, so well. There are a lot of issues (eg. problems with Ctrl-Alt-F1 or for example Konsole will have too small fonts), so I dont have recommendations at the moment. --Helmar Wodtke 15:39, 4 June 2008 (UTC)

Thank You very much! Now I'm nearly happy with the A110. :-)
There is one thing I like to try: making a virtuell XGA 1024x768 screen on an WVGA 800x480 Display. --Sven 15:47, 4 June 2008 (UTC)
1024x768 has some problems here. Amazingly 1280x1024 works ;) Try to attach an external monitor... That is a DDC related problem. --Helmar Wodtke 16:42, 4 June 2008 (UTC)
1024x768 works with Modifikation the xorg.conf Section Screen - change "virtual 800 480" to "virtual 1024 768" - after that Modifikation several Resolutions are available. If you login as user root you will see a nice clean desktop with 1024x768. - eik.s

xorg.conf

Could someone post the complete xorg.conf please? --Yorn 16:13, 4 June 2008 (UTC)

I've added my xorg.conf but it is very ugly.
BTW: there is a 800x480 pixel display similar to the original, with a 4-wire resistive touchpad. I is aroung 100,- Euros per piece. From 100 pcs. up, we could get a discount of approx 20%. --Sven 16:52, 4 June 2008 (UTC)
The Display thing sounds interessting, but I dont think, that there are enough interessted A110-users

Fn+F3

Is the Fn+F3 working? It used to work for me (lost the xorg.conf), using the xorg.conf from the wiki it is not working any more. Any ideas? --Yorn 15:00, 6 June 2008 (UTC)

Fn+F3 works with the xorg.conf from the LCD page if you install the driver as described on the page and change the line 
Option "FnHotkey" "LCD, CRT"
to 
Option "FnHotkey"
Switching to an external Monitor with Fn+F3 works like a charm. Change 
SubSection "Display"
   Modes    "800x600"
EndSubSection
to 
SubSection "Display"
   Modes    "1024x768"
EndSubSection
