XFCE screen rotate only choice normal

Please advice me with the XFCE settings. I have installed linuxcnc 2.7. Since I have a monitor placed "upside down" i need rotate the screen.
Unfortunately, in the monitor settings is only a possibility: normal. I also tried to screen rotate in the command line using xrandr. Not successfully.
jaro@CNC:~$ xrandr
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 480, current 1600 x 900, maximum 1600 x 900
default connected 1600x900+0+0 0mm x 0mm
1600x900 0.0*
1024x768 0.0
800x600 0.0
640x480 0.0
jaro@CNC:~$

jaro@CNC:~$ xrandr --output default --rotate inverted
xrandr: output default cannot use rotation "inverted" reflection "none"
jaro@CNC:~$

Connection VGA, Intel® HD Graphics, Intel® Celeron® Processor J1900

Thanks

Doesgives the same result?

Which distibution/vesrion are you running? (Debian Wheezy?)

I have installed Live/Install Image 2.7.3.

jaro@CNC:~$ xrandr --rotate left
usage: xrandr [options]
where options are:
-display <display> or -d <display>
-help
-o <normal,inverted,left,right,0,1,2,3>
or --orientation <normal,inverted,left,right,0,1,2,3>
-q or --query
-s <size>/<width>x<height> or --size <size>/<width>x<height>
-r <rate> or --rate <rate> or --refresh <rate>
-v or --version
-x (reflect in x)
-y (reflect in y)

etc.

That would be debian Wheezy then...

Correct syntax should be

I can try tomorrow on a wheezy box...

jaro@CNC:~$ xrandr -o left
X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 149 (RANDR)
Minor opcode of failed request: 2 (RRSetScreenConfig)
Serial number of failed request: 14
Current serial number in output stream: 14

Actually, the problem is that most probably the driver does not support rotation...

If you do:
These J1900 boards are newer than Wheezy, so the drivers are a bit outdated.
It might work on Jessie (with the latest rtai kernel ), but there is no ready-to-use install CD for this...

It is this problem only for non-free driver, or both drivers free and non-free?

AFAIK the Intel drivers are open source, there is no 'non-free' version

Thank you for your responses. I decided to buy an inexpensive card from NVIDIA and this solve the problem.

If I were you, I would first try with Debian Jessie to see if it is solved there -- it takes 10 minutes

You can download a Debian 'Live CD' from here (choose 'debian-live-8.3.0-i386-mate-desktop.iso' from the list). This will allow you to test without touching what you already have.

Choose 'Live (686-pae)' from the menu.


If it works, then it is probably worth going for it.
(LinuxCNC uses the RTAI kernel, not the one from Debian, but the version are about the same)

Going to NVIDIA might be a solution as well, but it also may screw up your latency -- from what I have read in this forum, NVIDIA cards are not always good candidates for low latency.
