Hi there,
The latest snap came out for vscode, but I cannot seem to launch it at all (via menus, terminal, run command, snap run command, etc.).
I can run the code command with flags to get the version, help, etc.
code -v
1.31.0
7c66f58312b48ed8ca4e387ebd9ffe9605332caa
x64
But if I run code . - no instance launches. Same with the menu, etc.
I was reading the man page for the snap command hoping to get some additional output as currently snap run vscode returns nothing at all. I have also re-installed the snap, rebooted, etc. as well.
Note that I am testing on 19.04.
cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=19.04
DISTRIB_CODENAME=disco
DISTRIB_DESCRIPTION="Ubuntu Disco Dingo (development branch)"
Any suggestions? Anyone else having similar issues
Thank you.
Interesting, I am using the code-insiders snap on Disco Dingo and working just fine.
For vscode it might be good to involve @lucyllewy or @wimpress
Yeah, I tested on another machine and it worked. 
I’m just trying to find a way to get more info).
Off to look through logs and debug commands.
I am just appending some debugging output for more info.

You are trying to start vscode as a super user which is not recommended. If you really want to, you must specify an alternate user data directory using the --user-data-dir argument.

This seems odd to me:

====
EDIT
- if I run the app with
sudo code --user-data-dir ~/tmp/vscode/ ., it will launch.
- reset permissions on my home dir; still no launch
- This is a test machine, considering nuking it. (stumped and wasting time. Would like to see if I can reproduce.)
EDIT2
- Created a new user (same install), the issue disappeared.
- Deleted original user.
- Then had the realization that it was likely extensions. (Wish I had tested)
- use settings sync, so wondering if my issue will return.
- Pretty obvious this is an issue on my specific machine/setup, so I think this thread should be considered closed/solved (per se) since there is nothing wrong with the snap.
EDIT3 (15:48 PST) - Came back on a FRESH install of 19.04. Just this snap. Nuked ~/snap/vscode, ~/.config/Code and ~/.vscode. Still the same behavior. Swap users, things come back for a time. 
sniff
EDIT4 - Purged all folders as described above. Uninstalled snap. Rebooted. Install snap. Now the snap launches again. 
OK, I am calling this out on it’s own.
This was a rough one.
So when it was working, and i was syncing down my cfg (settings sync), I caught this flying by:

Now as you can see, my disk is NOT full:
$ df -h

Turns out the fix is:
echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
(which will persist on reboot).
OW!
Just putting this in here in case anyone else comes across this.
