Nios 2 EDS not starting

Hi there,

i'm trying to get EDS to run on my Ubuntu 22.04. After following the README whichs content is duplicated here: https://www.intel.com/content/www/us/en/support/programmable/articles/000086893.html

I get several error messages when running ./eclipse-nios2.

The first one was:

xkbcommon: ERROR: failed to add default include path /tools/qt/5.15.6/1/linux64/rel/share/X11/xkb

My solution was to just create this path. After that i got:

xkbcommon: ERROR: 1 include paths could not be added:
xkbcommon: ERROR: /home/matthias/.xkb
xkbcommon: ERROR: Couldn't look up rules 'evdev', model 'pc105', layout 'us', variant '', options ''

to solve the path error i again just created it. But this "config" (?) file is missing.

Can someone help me out? What did i do wrong installing eclipse? How can i fix this?

Thanks in advance!

Matthias
