I am not able to use the shortcut key in Blender, although in Preferences > Input there is normal.
For example, I can't use key G for move , S for scale, R, X, Y, Z or Shift + D for duplication, but I can use Ctrl + A and various keys preceded by either Ctrl or Alt..
I have tried many times and more than one time I have to re-install Linux.
How do I solve this issue?
