Rotate the monitor-display and the screen-desktop in KDE


I have a monitor which I can rotate 90 degrees clockwise from landscape to portrait setting and vice versa. I'm looking for a setting (preferredly realized as a shortcut) to rotate the contents i.e. my (KDE) desktop along.

In Windows *cough* I use <ctrl><alt><arrow> to switch the up-direction of the display to where I want it. Something like that is what I'm looking for in KDE as well. (For my hardware setup look in my signature).

Yes, I know those. They are from the control center (I think system settings sub-menu ... or keyboard? Dunno, I' sitting in front of a windows box right now ). But they lack the desired rotation keys. How can I create them?

Krandr is an application that sits in the system tray and handles screen resolution and rotation for KDE. (Sorry can't find a link to it). Not sure if it supports shortcut keys as I'm not infront of my desktop at the moment.

I noted that there's some work toward automatic screen rotation (Google Search). At least one of those links mention a short Bash script bound to a shortcut key that might do what you want.

Let us know if you get it working.

Will do over the weekend and come back with the results.

This is part of my effort to create a multi user / multi seat setup in a congested space (more room when you can tilt the monitors ). Anybody with interest in this, feel free to support my feature request here: https://features.opensuse.org/310913. Thanks.

I thought the solution looked too easy/common.

@redgoblin Works like a charm. Thanks a load. I didn't find any possibility for a shortcut, though, same as you already mentioned. So, anybody who knows how to add that?

@GlennsPref You pulling my leg? Too easy/common? That's what the desktop linux user is drooling over . As to your first post: Do you know of a method to add to this list of shortcuts?

Thanks to both of you .

For rotation, write two scripts to do what you want (rotate and rotate back). When "krandr" doesn't qualify for this, have a look at "xrandr".

For shortcuts, have a look at "xbindkeys" and "xte" and at this text:
http://wiki.ubuntuusers.de/xbindkeys

For Ubuntu folks, there is a package tablet-screen-rotation-support that uses ACPI to detect the rotation and change the geometry.

I meant my attempted solution was too easy.

Besides they might be kde3.5 vintage/age.

Bluebox has a promising link, too bad my grade8 German fails me.

(it might not be German)

Using kde4 here, try this link. /home/$USER/.kde4/share/config/kglobalshortcutsrc

All the best, Glenn

ooops, I am sorry! Sometimes I'm simply not aware whether I'm just reading German or English.

Here's an even more detailed explanation of xbindkeys for the people with less specialized linguistic habits:
https://wiki.archlinux.org/index.php/Xbindkeys

And here is a very short explanation of xte:
http://bingnu.net/keybindings-with-linux/

xbindkeys is intended to run a command on a key press and should be the thing that is needed here.

xte can emulate complex X events on key presses, but I don't expect it to be necessary here.

Sorry to come back only this late. I had trouble with my setup which is only now resolved.

@ redgoblin & @ SaintDanBert: Automatic detection of a change of orientation would be nice. But the links are usually for netbooks / tablets and the like, I don't even know whether a "normal" monitor generates a signal when it is rotated (at least I found no pertinent information). So I'd settle for a manual setting. "Krandr" works with the mouse in a menu as posted, thanks.

@ GlennsPref & @ bluebox: openSuSE doesn't seem to know either "(x)bindkeys" or "xte" Are those two part of a package? Funny thing is, my installation doesn't know "Krandr" either, though it is there and works. I'm somewhat perplexed by this...

<edit> Btw. the second link of your last post times out, bluebox... </edit>

There's all types of Randr, krandr, xrandr

These pages are concerned with PC's

I've found the archlinux wiki to be very good.

Yes, I know. I still find it peculiar to have a working "*randr" on my system but YAST doesn't know about it. Now that you mention it, I didn't try xrandr from the command line, maybe it is there too.

Would you happen to know where I can find "(x)bindkeys" and "xte" or which packet they belong to?

Thanks for the links, I like the ArchWiki, too.
