No protocol specified Failed to open display about dwmblocks HOT 5 OPEN

The error you're getting suggests that dwmblocks can't talk to the X server. Most likely sometimes opening the X display failed for you but before this commit there wasn't proper error handling so it never crashed for you. I was already working on changing it so that it only opens the X display once rather than every time the root window name is changed. I just pushed this change so try it out and see if it helps.

@torrinfail, thanks. I'll give it a go and will report back after running for a while.

No crash so far. However, coming back after the screensaver had kicked in, the process is still running but nothing is showing from dwmblocks, instead I see the standard 'dwm-6.2' text.

Interesting. What screensaver utility do you use?(or do you just mean when X automatically makes the screen go black after a little while?) I tried to reproduce with xscreensaver and it worked no problem.

Sorry, I meant when X automatically makes the screen go black.
