I recently removed the nVidia drivers, and apparently that means that DISPLAY=:0 and not :1 😓

FYI: if there is only one X11 server running, just omit the display number and the xpra server should be able figure it out.

The commit above should try to handle the missing display more gracefully than with an assert.

Well, idk why nvidia drivers start :1 😅 Maybe it has something to do with gdm lockscreen + user display?

totaam commented 6 months ago

It depends on your distro, drivers, version, etc In some cases, having the nvidia drivers forces you to use X11, in which case the display manager (gdm or whatever) may spawn a new display after login. On other cases (ie: not nvidia, some other display managers, etc) the DM hands over the existing display to the window manager.
