Hello,
How can i install arandr in slitaz?
I need this tool to configure the display and for multi screen/desktop support in slitaz.
It is really related to lxrandr which is already included in slitaz but is not enought to properly manage the multi screen/desktop.
I used tazpkg to convert the debian package, but not good result, is installed i got the icon but the tool does not start.
I beg anyone is able to install arandr in slitaz to help! Thanks

I found the solution by myself !
I did not know that is possible to write a simple script to change resolution of many screens, but is possible and i did it.
If this can help someone else.. just paste into a new file with leafpad and save it with .desktop extension (for example save as 1024x600.desktop) than just click it to change resolution or device on fly.
1) Single screen 1024x600
[Desktop Entry]
Type=Application
Icon=display
Name=1024x600
Comment=1024x600
Exec=xrandr --output VGA1 --off --output LVDS1 --mode 1024x600 --rate 60.0
2) Single screen 1440x900 external
[Desktop Entry]
Type=Application
Icon=display
Name=1440x900
Comment=Start xrandr with settings done in LXRandR
Exec=xrandr --output VGA1 --mode 1440x900 --rate 60.0 --output LVDS1 --off
OnlyShowIn=LXDE
3)And now the best i did.. Dual display with extended desktop! First display below (netbook) and second display (external) on top so i can move windows, browser or file manager up or down the screens
[Desktop Entry]
Type=Application
Name=Dual
Icon=display
Comment=Start xrandr with settings done in LXRandR
Exec=xrandr --output LVDS1 --mode 1024x600 --pos 0x900 --rotate normal --output VGA1 --mode 1440x900 --pos 0x0 --rotate normal
OnlyShowIn=LXDE
That's all, this is just an example because is what i need but you can change the resolution the rate or the screen position if you need different settings.
The only thing i need to fix is the desktop wallpaper (that is still not stretched correctly) and icons behaviour, maybe because openbox consider the desktop smaller than what really is.
I fixed the desktop wallpaper problem by using a bigger wallpaper and by changing the desktop wallpaper settings, this is a nice trick and work but is not the correct solution.
If someone knows how to solve the desktop and icons behaviour i appreciate it.

Well done!
I want to collect same tricks and add them to TazPanel.
This is very first time I see multi screen desktop in my SliTaz, and its worked! At left side my netbook's screen 1024×600, at right side — 17" monitor 1024×768, and my code is:
xrandr --output LVDS1 --mode 1024x600 --pos 0x0 --rotate normal --output VGA1 --mode 1024x768 --pos 1024x0 --rotate normal
We have PCManFM managed desktop wallpaper & icons, and there is no solution for icons placing (always in top left corner on top left monitor), and only your tricky solution for wallpaper — using large picture and select "Mode: Tile the image to fill the entire screen".

I am very happy to share Aleksej and happy that is worked for you too.
Now we have to hope that someone can help us to fix the desktop and icons placing by suggesting a solution, but so far is ok we have multi screen in slitaz.
Would be nice if arandr be ported to slitaz package list too, to make multiscreen easy for everybody.
If somebody experienced problem with the panels it can be fixed with easy steps..
Just by using primary (or secondary) screen pixels dimension in panel settings, assuming that your screen is 1024 pixel large and located to the left, you can set the panel dimension to 1024 pixel to have the panel only shown in one screen alligned to the left for example or you can change it the way you like just take care of position to keep it visible!
It's nice to have multiscreen in slitaz !

@ arandr: You're the greatest in the world!!!!
I have just made a search for this topic (multi-screen in slitaz) and your post came first.
I immediately went to our system and reconfigured it for good!
I just have to discover how those changes are made permanent, surviving power-cycling the system, apart from editing [c].profile[/c]...
Thank you so much!

Hi there two years later! 
Now I confirm that old trick no more works for me.
On the external monitor I see a copy of my desktop, stretched or cropped depending of SliTaz version — tried my current upgraded SliTaz with many packages installed, and frugal installation of SliTaz Rolling @ 210914.
«Monitor Settings» from Applications menu shows only one monitor.
And here terminal output of xrandr:
[c]tux@slitaz:~$ xrandr --output VGA1 --mode 1360x768 --pos 0x0 --rotate normal --o
utput LVDS1 --mode 1024x600 --pos 1360x0 --rotate normal
xrandr: Failed to get size of gamma for output default
warning: output VGA1 not found; ignoring
warning: output LVDS1 not found; ignoring
tux@slitaz:~$ xrandr
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1024 x 600, current 1024 x 600, maximum 1024 x 600
default connected 1024x600+0+0 0mm x 0mm
1024x600 0.0*
tux@slitaz:~$[/c]
Now I used external TV/Monitor with resolution 1360×768 and my old netbook with 1024×600.
——
Seems like it old bug somewhere in the X.Org packages. If memory serves it was in the SliTaz 4.0 too, but later it was fixed.
Multi-monitor configuration... Mmm... Xinerama extensions?..

I've had a lot of occasions where a working external screen resolution would have come in handy.
is there any solution or workaround for this?
Offline
I've used this to get slitaz to output to two monitors successfully.

You have to install it yourself though.

@nitrogen_widget: on desktop, when i plug in my external screen i get a copy of my laptop screen.
with arandr from the site i can only detect my default laptop screen. very similar to slitaz's monitor settings tool.
does it have something to do with running a frugal install?
Offline
It probably has something to do with your video chipset & the driver you have installed.
I was using older hardware with an older agp card with the opensource drivers.
Offline
@nitrogen_widget: i have the same problem on two different laptops.
my main one has an intel onboard graphics chip.
which slitaz version are you using?
