[SOLVED] Xcompmgr in autostart.sh makes keyboard/mouse unusable
  • ms3811ms3811 July 2010
    I'm using an intel card (945GM chipset). If I enable the shadow effects after login by right-clicking the desktop, Desktop Effects, Activate Shadow, everything works fine and the shadow effects are activated.

    But if I add the line "xcompmgr -cC -t-3 -l-5 -r5" to autostart.sh, the screen freezes after login. The desktop renders, but the mouse cursor is unavailable and the keyboard is not responsive either. This is not a hard freeze, CTRL+ALT+BACKSPACE does kill the window manager and text only works fine. I can also startx as root and it works fine (root does not have xcompmgr activated).

    This is not critical and I can live without the eye candy. But if anyone already knows of a workaround or solution, it would be helpful. The theme I'm using has the same color for lxpanel as for the status bar in many applications, so the shadow is useful in creating a distinction.

    Try sleep 5 && xcompmgr -cC -t-3 -l-5 -r5 to slow down execution.

    Sleep just delays the inevitable by specified time.

    I looked at Xorg.0.log with and without and this is what I see:

    without the line in autostart.sh:

    However, with the line in autoexec.sh, this is what it has:

    ....end excerpt....

    If you notice, the modules for "mouse" and "kbd" are unloaded when xcompmgr is activated in autoexec.sh. Any ideas why that would happen? I tried to tail /var/log/messages when running the xcompmgr command manually, and it doesn't do anything. I mean, the effects load correctly and nothing posts to /var/log/messages.

    I think I must be one of the people with the least attention to detail!!!

    Not sure what causes the "UnloadModule: mouse" and "UnloadModule: kbd" in Xorg.0.log or why that's related to this issue, but the problem turned out to be a missing "&" in the autoexec.sh to make xcompmgr to run as a background process.

    Sorry for wasting everyone's time.
