portrait mode displays
« on: January 01, 2012, 03:32:42 PM »
Hi,

I am sure that this issue has come up before, but I do not know where to look.
Can anyone tell me the easiest way to get a screen working in portrait mode with TinyCore?

Peter.

Using Xorg you can rotate, flip, ... screen. Setting can be change with lxrandr for example.

Thanks.

Can this be achieved using the display utilities tools in the control panel somehow or is there some xorg command I need to run at command level?

Hi Tuftec
Try this:
Install  lxrandr.tcz
Open a terminal and type  lxrandr --help

Installed lxrandr. --help option appears not to work. Just starts the GUI interface as normal.
There is no obvious option in the GUI interface to rotate the screen. I just have a limited range of oprions to change the screen resolution.

Do I need to add something to the xorg.conf file?

I tried xrandr -o left.
That just gave errors. BadMatch (invalid parameter attributes).

Sorry, lxrandr was a typo before instead of xrandr.

xrandr -o left

put my notebook to portrait mode. Type

xrandr -o normal

to go back to original or type

xrandr -o right

to get portrait mode in the other direction.

Hi Tuftec
Take a look through the xorg.log file and see what it says about xrandr (or randr). I read that your
driver has to support rotation in order for it to work.

Try rotating just one --output
This works for me.

I tried xrandr -o left earlier and it did not work. Just gave errors.

The h/w I am running on is very simple (eBox) so does not have a very sopgisticated video chip.

Hiro, not sure what you mean by your comment. Where do I add the --output line? Is this in xorg.conf?

Are there other details to add?

Peter.

xrandr --output LVDS1 --rotate left works here (see xrandr --help)

I have tried the various suggestions.

I think the problem I have is that the display hardware is very simple.

Can the display be rotated when using the basic built in???? video drivers?

I use arandr http://christian.amsuess.com/tools/arandr/ , dependencies are Xorg-7.x-bin.tcz and pygtk-2.7.tcz, but they serve only temporarily.
Start ./arandr, setup your screen (output-->your_monitor->orientation->left), test with apply,  and if all goes well save setting (layout-->Save as), this creates a script that started returns monitor as you set (with xrandr command).

If xrandr doesn't work arandr won't either.
Someone already said you should look into Xorg.log and at least post the error you get when running xrandr.
