I just dist-upgraded my Debian machine from jessie to stretch and now my mouse pointer in fvwm (v2.6.7) sometimes disappear.
The pointer is visible as long as it is located over an xterm window (icon is a vertical line, with small curly things at the top and bottom).
But as soon as I move it up to the window’s title or hoover above any border, it disappears.
Same thing on the root background.
Same thing above the entire window of some windows, e.g. Emacs.
Same thing above fvwm menus.
If i click somewhere on the background, the fvwm menu appear, and I can move the invisible mouse pointer to select items.
This is annoying.
If I run ‘xsetroot’, the background color becomes black and the cursor becomes visible, as long as I hoover above the background.
The cursor becomes the big “X-windows cross” (a big X). So now I have a working mouse pointer over the root background.
But when I hoover the mouse over a window title or border, it still disappears.
When above the textbody of an xterm window it is still visible.
Since the mouse is working, and some pointer icons work, I suspect this is a fvwm issue, showing the wrong icon when above window titles/borders/etc.
I’m using the Nouveau Xorg-driver (for my really old Nvidia Geforce4 MX 4000 gfx card).
I’ve tried forcing HW mouse off and SW mouse on - same results.
I’ve removed all my own .fvwm and .xinitrc settings.
With the default fvwm setup, the standard mouse pointer is still missing.
Can somebody help?
