I use exwm as my window manager. Since commit 483c5e9, my session starts
up as a blank screen (emacs responds to keyboard shortcuts, though). I
have heard user reports (at [0]) that switching virtual desktops on
xmonad also leads to a blank screen, and I believe this is another
instance of the same bug.
The problem happens without native compilation enabled. I have verified
that reverting commit 483c5e9 fixes the problem.
Best,
Mauricio

It still responds to (at least) some keyboard shortcuts (I can close with C-x C-x) and if the menu bar or the toolbar are active they also respond to some mouse clicks. Interestingly, the problem does not show up if I launch Emacs in an XMonad session inside XMonad using xephyr. Best, Ramon ^ permalink raw reply [flat|nested] 12+ messages in thread

I'm a bit too dense to understand what you are doing and what does not work for you. Is the behavior of Xmonad showing an Emacs frame OK as long as you do not switch to a different virtual desktop? Are tool and menu bar shown in the blank screen case? Does a blank screen blank out other things besides Emacs. Does it work when Emacs is not supposed to be shown on that "different virtual desktop"? In either case please try to identify the commit that broke this - I have my slight doubts that it is 483c5e9. Could it be already a190b4c? As soon as you have done that, I would like to give you a few instructions to make the code that broke this a NOOP and, in the worst case, make its execution optional on tiling WMs. Thanks, martin ^ permalink raw reply [flat|nested] 12+ messages in thread

Could it be already a190b4c? Bisected the following behaviour on Xmonad to 483c5e9. In the screenshots below a red or black border indicates which frame Xmonad thinks is selected or unselected, respectively. Similarly a filled or hollow box cursor shows which frame Emacs thinks is selected or unselected, respectively. 0. emacs -Q [-- Attachment #2: 0.png --] [-- Type: image/png, Size: 13880 bytes --] [-- Attachment #3: Type: text/plain, Size: 142 bytes --] 1. C-x 5 2 [Ignore the missing scroll bar for now.] 2. (visible-frame-list) C-j C-m 3. (mapcar #'frame-visible-p (frame-list)) C-j C-m [-- Attachment #4: 3.png --] [-- Type: image/png, Size: 28052 bytes --] [-- Attachment #5: Type: text/plain, Size: 413 bytes --] 4. Switch to another workspace. At this point Emacs thinks neither frame is visible (I'm guessing they're all iconified). I know this because in my customised compilation-finish-functions I do a notifications-notify for long-running compilations, but only if the compilation BUF does not satisfy (get-buffer-window BUF 'visible). 5. Switch back to the workspace with Emacs. 6. Repeat steps 2-3. [-- Attachment #6: 6.png --] [-- Type: image/png, Size: 18502 bytes --] [-- Attachment #7: Type: text/plain, Size: 295 bytes --] Note that the unselected frame is still iconified and lacks a toolbar. Switching to that frame using Xmonad bindings would deiconify it. 7. C-x 5 o [Nothing changes.] 8. (select-frame (next-frame)) C-x C-e C-m [Nothing changes.] 9. (select-frame-set-input-focus (next-frame)) C-x C-e [-- Attachment #8: 9.png --] [-- Type: image/png, Size: 27986 bytes --] [-- Attachment #9: Type: text/plain, Size: 184 bytes --] This deiconifies the frame on the right, which now receives input, but Xmonad still thinks the frame on the left is selected. 10. C-s focus RET C-e C-x C-e [AKA repeat step 9.] [-- Attachment #10: 10.png --] [-- Type: image/png, Size: 22696 bytes --] [-- Attachment #11: Type: text/plain, Size: 96 bytes --] Back to where we started, with both frames deiconified. 11. C-x C-e [AKA repeat step 9.] [-- Attachment #12: 11.png --] [-- Type: image/png, Size: 22899 bytes --] [-- Attachment #13: Type: text/plain, Size: 1899 bytes --] So to me it looks like some state/hint either on Xmonad's or Emacs' side isn't refreshed or heeded when switching workspace. I actually kind of like that Emacs frames on workspaces other than the current one are considered invisible now, because of course they're not visible :). But switching back to that workspace should ideally make all frames visible again. I'm certain that there are both Xmonad and Emacs hooks that allow the user to program this, but previously this wasn't needed. BTW, I forgot to include in the recipe above that (mapc #'make-frame-visible (frame-list)) also changes nothing. It seems that the only thing that deiconifies frames is giving them input focus. [ P.S. Let me know if fullscreen inline screenshots are annoying, and what to do instead. I passed the images through pngquant so that at least their size is small. ] > As soon as you have done that, I would like to give you a few > instructions to make the code that broke this a NOOP and, in the worst > case, make its execution optional on tiling WMs. Thanks, -- Basil In GNU Emacs 28.0.50 (build 1, x86_64-pc-linux-gnu, X toolkit, cairo version 1.16.0, Xaw3d scroll bars) of 2021-05-13 built on tia Repository revision: 43701a84367b76ccc93ad46f89110486988eec10 Repository branch: master Windowing system distributor 'The X.Org Foundation', version 11.0.12011000 System Description: Debian GNU/Linux bullseye/sid Configured using: 'configure 'CC=ccache gcc' 'CFLAGS=-O2 -march=native' --config-cache --prefix=/home/blc/.local --enable-checking=structs --with-x-toolkit=lucid --with-file-notification=yes --with-x' Configured features: ACL CAIRO DBUS FREETYPE GIF GLIB GMP GNUTLS GPM GSETTINGS HARFBUZZ JPEG JSON LCMS2 LIBOTF LIBSELINUX LIBSYSTEMD LIBXML2 M17N_FLT MODULES NOTIFY INOTIFY PDUMPER PNG RSVG SECCOMP SOUND THREADS TIFF TOOLKIT_SCROLL_BARS X11 XAW3D XDBE XIM XPM LUCID ZLIB ^ permalink raw reply [flat|nested] 12+ messages in thread
