gui does not open #7077

i tried clearing the data files i think there's still something on my computer but for some reason it opens but the gui does not

for some reason it opens

What is "it"?

Is there any message displayed on the screen?

no message on the screen but i can't use it because after it loads it does not work, and this was after i got bitcoins and i had it running a long time and the debug says it did not exit safely or something, but it does not work when i load it up

program opens but the gui does not appear i don't get why

Can you post what debug.log from the datadir says?

i cleared all the data but yet still says this everytime i reopen it

no error message except for exiting

It is possible that the GUI is outside the screen area. This usually happens when you had a second screen connected and disconnected it, or changed resolution.

I brought up this concern when this feature was first introduced: #2393 .

Unfortunately it saves the coordinates somewhere in the registry (in case of windows), so moving/deleting your data directory won't solve it.

See #3364 (comment) for workaround. Let us know if that worked.

Alternative for 0.12 release: If #7006 gets merged, you could pass -resetguisettings.

@laanwj i don't have two screens

Have you tried the workaround anyway? Possibly delete bitcoin-qt's entire registry key. It's virtually the only remaining source of problems once you've removed the datadir.

You could also try PR #7006 (https://bitcoin.jonasschnelli.ch/pulls/7006/) and see, if you can pass -resetguisettings. Would be good to here if this could solve your problem.

the workaround worked

The issue was very likely the problem mentioned by @laanwj (window position offset). Can be cured by #7006.

OK, good to hear
