I have not figured out how to re-run configure to disable the need for
sudo. So instead I am doing "sudo make install" and then removing the
setuid bit from weston. This certainly does make things better.
I have also tried resetting the ownership of all the thing installed
back to me. This made no difference.
With the fixes to remove asking for EGL_DEPTH and turning off setuid, I
can run weston under X and I get a mostly-black window. It locks up X
for a few seconds after the window appears. The window shows a small 4x3
icon in the top-left corner with a ">" in it, which I suspect is an icon
to launch a terminal. The window also shows a moving cursor that is not
the hardware cursor (this can be seen if you move the mouse fast or out
of the window, the cursor remains). Pointing at the icon makes it "light
I can then run the various clients. Most of my tests have been with
weston-terminal. Running them also locks up X for a second or so. No
visible thing happens on the screen, but moving the cursor around
reveals that there is an invisible "window": drag events are reported by
the client inside it, and the cursor changes to show the edges. I have
typed a "touch foo" command into the terminal and determined that it ran
the command. I can resize these windows as well, but if I move too much
weston crashes and the client exits at the same time. I have attempted
to move the window so that it obscures the "icon" in the top-left, but I
have either not succeeded in moving it to that location or it does not
actually obscure it (ie it is invisible, not composited, or below the
icon). The "flower" client reveals the flower shape as the cursor
changes when you enter/exit the window.
Attempting to run weston outside of X exits immediately after locking up
the screen and keyboard. I have not attempted to do this while X really
is not running, however (for some reason Alt+F1 does not work to get
back to the terminal, but Alt+F7 does get me to X and *then* Alt+F1
works, so it looks like I need X running to avoid locking up my entire
Is there any chance my old graphics card is to blame? However nouveau
seems to work fine in this card, and OpenGL programs run. Also weston
certainly drew *some* graphics (that icon, it's glow, and the cursors).
Is the removal of EGL_DEPTH to blame for this?
Is it easy to fix the permission problems? I would like to do it
correctly, rather than just chmod +rw on all the files and sockets.
Another worthwhile idea would be to fix weston "make install" so that if
you are not root it detects this and does not bother trying to setuid.
