Hello, To add, I found gksudo might be helpful.
I found issue mentioned here: https://bugs.launchpad.net/ubuntu/+source/ubuntu-themes/+bug/1723422 and work around https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1724078/comments/4 after that, I found the following issue: https://ubuntuforums.org/showthread.php?t=1803102 but now if I do "gksudo ./a.out" it is just exiting without any message or log. If I use "gksudo gdb ./a.out" and try to run, cursor is just blinking and nothing is showing up.
