Aloha - of course this could be a sublime text issue, but here goes the issue just in case someone can point me in the right direction.
I have been using Sublime 3 on Ubuntu without issue. Yesterday my computer froze up and I had to hard reboot. Sublime text was running when I had to do the hard boot. Then when computer reloaded, I could not open sublime text, the icon shows in the left sidebar as sublime text is running when I open it, and when I use "alt + tab" to rotate through open applications it is there as an icon. However the application is just not actually opening for me to use it, the GUI is just not showing. If I "alt+tab" to it, nothing.
I uninstalled and reinstalled Sublime Text 3 also, but still the same issue.
