Raspberry Pi 'official' Display
 

I picked up one from our local MicroCenter and it works fine with Slackware using the SARPI install in case anyone wants to get one.

I do have a couple questions though. Can X/KDE still support screen rotation and/or scrolling?
Also what is a more lightweight window manager I could use?

Not sure about screen rotation. Xfce is a good window manager and not as resource-heavy as KDE.

KDE is supposed to be able to do screen rotation but when I go into the display settings there is only one option in the rotation drop down.

Problem I'm having is there are a few applications whose dialog boxes are bigger than the display so I need to rotate or scroll to see them.

Try using xrandr.

I would try explore the kernel command line parameters?

Xfce supports rotation.

Hi,

You could try LXDE. Look at;LXDE - Wikipedia

Hope this helps.
Have fun & enjoy!

Sorry to revive an old thread, shortly after this my son was in the hospital then we have the summer break from school so I'm finally getting back to it.

I tried the options in /boot/config.txt https://www.raspberrypi.org/document...g-txt/video.md

I tried xrandr https://askubuntu.com/questions/9581...-most-easy-way

I also get the message

So it appears I have to add a mode, I see how to add other resolutions but not the rotate option

/boot/config.txt lcd_rotate=2 does flip but 1 oe 3 doesn't do anything.

I did manage to get rotate working. I downloaded rasbian to test with and found that

in

works, then run a shell script to adjust the pointer input

I overwrote my Slackware install with rasbian by mistake so I installed slackware again on another microSD card and tested and it worked, not sure why it didn't before so it must have been a pebkac error.
