After an update, Krita does not show menu bar. I'm using Ubuntu 18.04. GNOME desktop.
I deleted the kritacr file and reopened Krita...same. I uninstalled Krita and searched for and deleted all left-behind files with the name Krita. Reinstalled Krita from http://ppa.launchpad.net/kritalime/ppa/ubuntu. Open Krita...same. Opened Kritac and found an entry: MenuBar=Disabled. I changed it to be =Enabled and saved Kritac. Opened Krita...same. Opened Kritacr and found the entry MenuBar and found it was again =Disabled
I uninstalled Krita. Found the 'left-behind' file of Kritacr, opened and reset MenuBar to Enabled. Reinstalled Krita. Before opening, I checked Kritacr and found the MenuBar=Enabled. Opened Krita and ...same. Opened Kritacr and found the MenuBar=Disabled. It had reset to default. I'm lost.

I'm running the Krita 4.0.1 Linux appimage and my ~/.config/kritarc file doesn't have a 'MenuBar=' entry. I added a 'MenuBar=Disabled' line and Krita ran with the menu bar showing. (I've also tried it with the Krita 4.0.3 appimage.) This is strange.

Can you download and run the appimage instead? It's at: https://download.kde.org/stable/krita/4 ... 4.appimage
(Remember to make it executable.)

Also, could you try deleting the 'MenuBar=' line from your ~/.config/kritarc file, as an experiment?

I first tried deleting the MenuBar=Deleted entry from Kritarc. No help. I purged all files with 'Krita' in the name. Downloaded ...appimage and made executable, ran and Krita opened. Same result. The new Kritarc has, once again, this entry:
[krita]
MenuBar=Disabled
Maybe I'm asking for the wrong thing. There used to be a panel with text/dropdowns. Like 'select' or 'image,' or 'filters.' I'm calling that a 'menu bar.' Maybe I still have a 'menu bar.' The only thing on it is a few icons representing 'open,' 'save,' 'undo' etc. I'm looking for the drop-down menus.

I don't use Krita but the normal keyboard shortcut to toggle menu bars is CTRL + M

HTH!

You're correct in that you don't have a Menu(bar) (File, Edit, View, Image, etc) but your Toolbar (some configurable icons) is there. The only way I know to get rid of the Menu is to select it for hiding in the Canvas Only mode (which is toggled by the Tab key) by ticking it in Settings -> Configure Krita -> Canvas Only settings (but you can't see Settings because you don't have a Menu.) The default, as installed, settings do not usually hide the Menu though.

As a long shot, have you tried pressing the Tab key to toggle Canvas Only mode? Apart from that it's very puzzling and would need advice from a developer.

You say this happened after an update. Can you say which version it was when it used to work and what the update was?

Note: Cntrl+M doesn't toggle the menu in Krita, it calls up the Colour Adjustment filter window.

IT HEALED ITSELF!
Following your suggestions, I opened a file and tried the tab to open full screen. That worked. I tried cntr+M and as posted, it opens color mixer. While In full-screen mode, I closed the image file, leaving Krita with an empty full screen. I closed Krita.
Then restarted Krita and it opens with a menu bar! Since I have no idea what I'm doing, just trial and error, I can only assume that Krita got tired of this game and healed itself!
Thanks for all the great responses!

I'm glad you've got the Menu back but I don't think you're 'safe' yet. After a bit of experimenting, I now have the 'MenuBar=Disabled' item in my kritarc file and you probably do too. It's related to the Canvas-only screen settings.

Go to Settings -> Configure Krita and click Canvas-Only settings in the left sub-pane. I think you'll find that the Menu item is ticked. This means that your Menu will be hidden when you press the Tab key (Canvas-only mode toggle). A more usual arrangement would be to have Menu unticked and the Toolbars, Toolbox and Statusbar items ticked, or whatever you want to be hidden in Canvas-only mode. As long as you're aware of what's happening and that the Tab key will toggle between two modes of screen content presentation, as determined by those tick marks.

This raises the question of how the Menu item got ticked but that's for you to figure out

Got it, thanks!
I explored the 'canvas only' settings and personalized it.
The 'settings' menu is new to me. Previously, I just used Krita as-is. I'll make it more my own as time goes by.
As to how the setting gets configured, after all my uninstall, purge, reinstall from different sources, I'm convinced it is the default for 4.03. Maybe it is linked to Ubuntu 18.04, but that doesn't seem logical

I am not sure if purge removes the kritarc from .config...

maybe I used the wrong term. I did a file search for anything named 'krita' or having 'krita' in the name. I sent them all to the trash.

Today, I'm back where I started.
No menu bar and no tab to toggle full screen.
I have Ubuntu 18.04 and I am using the Ubuntu software updater. On start-up, it automatically updated several items. Later in the morning I opened Krita and found it reverted to whatever settings cause my issue.
I uninstalled Krita and removed Krita files. I installed Krita app-image. I changed the Kritarc to show 'menubar=Enabled' and saved the file. I then opened Krita.
Same issue. Unable to toggle tab-full screen. Unable to see the menu bar.
Have I run across a bug? is it worth trying to submit a bug report? I've never done that and I'm a little unsure of how.

... Isn't ubuntu using gnome? Doesn't that have the menubar in the top-topbar?

There is a title bar at the top. "There used to be a Krita panel with text/dropdowns. Like 'select' or 'image,' or 'filters.' I'm calling that a 'menu bar.' Maybe I still have a 'menu bar.'

Yes, that's the menu, and ubuntu likes to take the ubuntu out of the window and display it somewhere else. I guess they've got a bug with that... They changed technologies in 18.04, and bugs like these are not unlikely to happen. I would use the Plasma desktop provided by Kubuntu instead.

Oh, the lengths I will go to, just to use Krita.
I managed to get KDE Plasma working on the Ubuntu OS. But it seemed kinda' unstable for daily use, I had to open the settings and select KDE on start-up, then in use, it just didn't feel right. So my, already high frustration, built even higher. So I reasoned that the KDE Plasma I was seeing wasn't really what I have used before, it was KDE imposed on Ubuntu, not integrated with Kubuntu.
So, only having used Ubuntu for a week or so and not keeping much 'down here' - most of my stuff is actually 'out there'- I, on another machine, downloaded a Kubuntu 18.04 ISO and created a Live disk. Then wiped and installed Kubuntu instead of Ubuntu.
So, now I use Kubuntu 18.04 LTS.
Krita works as expected.
Oh, the lengths I will go to, just to use Krita.
Thanks, everyone for your patience with me. (I still think there is a bug in the Krita install package intended for Ubuntu 18.04)
